=1. Introduction=

SBS-modified roofing membranes, often referred to as "SBS roofing" or simply as "SBS", are relative new-comers to the world of modified bituminous roofing products.  SBS-modified roofing membranes comprise a substantial portion of the flexible membrane market, which has largely replaced traditional built-up roofing felts. While offering the higher performance and versatility of a flexible membrane, SBS-modified roofing membranes are also generally compatible with asphalt products, and are therefore useful for re-roofing. 

SBS-modified roofing membranes are just one type of modified bituminous roofing.  They are flexible membranes manufactured in rolls and are thermoplastic in nature but display variable elastomeric properties, primarily because of the modifiers blended with the bitumen. These membranes are generally manufactured using three materials: (1) modified bitumen, (2) reinforcement fibers, commonly woven as a sheet and embedded within the membrane (these fibers may be glass, polyester, or a blend of the two), and (3) a surface coating, such as stone or ceramic granules. The performance of these membranes (for example, their flexibility or ability to retain their shape under higher temperatures) may be compromised by subtle, seemingly inconsequential changes in composition. 

The formulation of the bitumen is critical, particularly when its physical properties are modified by the addition of polymers. Bitumen is most commonly modified with styrene butadiene styrene (SBS) or atactic polypropylene (APP; see separate section in this Manual). The manufacturer must ensure that a suitable degree of compatibility exists between the bitumen and the polymer and that a thorough mix has been obtained. The careful selection and combination of bitumen and polymer (the type of modifier, the percentage of polymer used, etc.) determines the physical properties and long term performance of the modified bituminous “binder” ('''''the meaning of this sentence is unclear; what exactly is the 'binder' and how is it related to the bitumen and polymer used to modify the bitumen? - isn't the "binder" the same as the polymer such as SBS or APP, or is it something else?  The structure of this sentence suggests that the polymer and the binder are actually two different things'''''). The binder provides the membrane with its waterproofing capability and may impart the following properties: 

* low temperature flexibility 
* elasticity 
* high temperature resistance to flow 
* resistance to aging 

The bitumen utilized for oxidized bituminous membranes has been “blown” (clarify), similar to roofing asphalt (see Section 3.9.1). This produces a higher softening point and, therefore, a more useful temperature range. ('''''This means what?  That the membrane can be applied using a wider spectrum of temperatures?  That it retains its shape under higher temperatures?   If so, then let's say that, i.e.  "Injecting oxygen into the bitumen results in a higher softening point, which makes installation easier and means the membrane will retain its shape under higher temperatures".''''')

The physical properties of the binder are further enhanced by applying it to or embedding it in a carrier or reinforcing mat, most commonly a textile such as:
 
* non-woven spun-bonded polyester 
* woven polyester scrim 
* fibreglass mats 
* woven fibreglass cloth 
* combinations of the above 

The type of reinforcing selected depends on the end use and desired physical properties of the finished products. The weight, quality, tension during manufacturing, and method of saturation and coating of the reinforcing are some of the factors governing the final product's performance. Some polyester modified membrane manufacturers use oxidized bitumen to saturate the reinforcement, particularly when “heavyweight” material is used. 

Membranes are usually surface treated with a parting agent so they do not stick in the roll. Surfaces that will be hot asphalt applied are usually sanded while torch-applied surfaces use polyethylene or other thermofusible films (materials that can be bonded with heat). Exposed surfaces may be embedded with mineral granules (usually ceramic chips or slate flakes) or laminated with metal foil for ultra-violet protection. As an alternative on roofs with minimal slopes, a pour coat and gravel surfacing may be installed over some membranes, although this makes the quality of application difficult to inspect and may lead to problems with membrane slippage due to the weight of the cap sheet and surfacing. ('''''Is this still done?  If not, we should remove this information as it is extraneous.''''')

=2. Definitions and Terminology=

===2.1 COMPOSITION===
Bituminous and modified bituminous flexible membrane systems are composite sheet membranes which are thermoplastic in nature but display variable elastomeric properties when modified.  These sheets generally consist of bitumen (oxidized or modified), reinforcement, and surfacing materials.  The performance of these membranes may be compromised by subtle, seemingly inconsequential changes in composition.

The formulation of the bitumen is critical, particularly when its physical properties are modified by the addition of polymers.  Bitumen is most commonly modified with styrene butadiene styrene (SBS) or atactic polypropylene (APP).  The manufacturer must ensure that a suitable degree of compatibility exists between the bitumen and the polymer and that a thorough mix has been obtained.  The careful selection and combination of bitumen and polymer (the type of modifier, the percentage of polymer used, etc.) determines the physical properties and long term performance of the modified bituminous &#8220;binder&#8221;.  The binder provides the membrane with its waterproofing capability and may impart the following properties:

*low temperature flexibility
*elasticity
*high temperature resistance to flow
*resistance to aging

The bitumen utilized for oxidized bituminous membranes has been &#8220;blown&#8221;, similar to roofing asphalt (see Section '''''Reference needed''''').  This produces a higher softening point and, therefore, a more useful temperature range.

The physical properties of the binder are further enhanced by the imposition by saturation or coating onto a carrier or reinforcing mat, most commonly a textile such as:

* non-woven spun-bonded polyester
* woven polyester scrim
* fibreglass mats
* woven fibreglass cloth
* combinations of the above

(Some polyester modified membrane manufacturers use oxidized bitumen to saturate the reinforcing, particularly when &#8220;heavyweight&#8221; reinforcing is used.). The type of reinforcing selected depends on the end use and desired physical properties of the finished products. The weight, quality, tension during manufacturer, and method of saturation and coating of the reinforcing are some of the factors governing the final product's performance.

Membranes are usually surface treated with a parting agent so they do not stick in the roll. Surfaces that will be hot asphalt applied are usually sanded while torch-applied surfaces use polyethylene or other thermofusible films. Exposed surfaces may be embedded with mineral granules (usually ceramic chips or slate flakes) or laminated with metal foil for ultra-violet protection. As an alternative on roofs with minimal slopes, a pour coat and gravel surfacing may be installed over some membranes, although this makes the quality of application difficult to inspect and may lead to problems with membrane slippage due to the weight of the cap sheet and surfacing.

The <b>thickness</b> of the membrane should be suited to the method of application.  Torchable membranes must be thick enough to allow the underside to be melted without burning through to the reinforcing and thin enough to be manageable in winter conditions.  Hot asphalt applied (mopped) membranes should be of sufficient thickness to perform adequately but should not act as a &#8220;heat sink&#8221;, lowering the temperature of the asphalt before a sufficient bond is achieved.  Manufacturers often refer to membrane thickness in one of two ways.  &#8220;<b>Nominal Thickness&#8221;</b> usually refers to the thickness <b>including any granular finishes</b>.  <i>As the granular surfaces do not contribute to the performance of the membrane (except as ultra violet protection and appearance), thickness measured &#8220;at the selvage edge&#8221; usually gives a more accurate indication of the physical properties of the membrane related to thickness.</i>

===2.2 PERFORMANCE===
The physical properties of the membranes available today vary greatly. Each membrane manufacturer &#8220;tackles&#8221; the problems of roofing technology differently, based on individual design criteria. The design authority, in consultation with the manufacturers, must identify the properties most important for the performance of the roof system on <b>an individual project basis</b>.

As a precaution, RGC has accepted the following performance limitations, based on the lowest expected in-service temperatures of the membrane:

* Temperatures warmer than -10&#176;C (+14&#176;F) require membranes with a minimum tensile strength of 150 N/50 mm.
* Temperatures warmer than -18&#176;C (0&#176;F) up to -10&#176;C (+14&#176;F) require a base sheet or cap sheet with  a minimum tensile strength of 294 N/50 mm (CGSB 37-GP-56M Grade 1).
* Temperatures colder than -18&#176;C (0&#176;F) require a base sheet or cap sheet with a minimum tensile strength of 785 N/50 mm (CGSB 37-GP-56M Grade 2).

The design of a roof membrane system is contingent upon many factors and is not solely a function of design temperatures. Consult the membrane manufacturer for assistance with design considerations and membrane selection.


<u>RIDGING & WRINKLING OF MODIFIED BITUMEN MEMBRANES</u> ==
Reprint of CRCA Technical Bulletin, Volume 43, published October 1995:
   
Can roofs be &#8220;perfectly&#8221; constructed&#8204;  Under most circumstances, the answer to that question would be &#8216;No&#8217;.  Minor aesthetic imperfections, that have no bearing on performance, will always develop due to the materials used and the conditions under which they are installed.
   
Modified bitumen membranes, with their relatively thin protective surfacing (primarily ceramic granules or metal foils), can be particularly susceptible to the occurrence of these blemishes.  Unlike traditional built-up roofs, these membranes are not &#8220;hidden from view&#8221; by a heavy top pour of asphalt and gravel.  The reflective properties of their protective surfacing will allow many minor anomalies, such as deck or insulation unevenness, to readily telescope through to the roof surface.  Over time, due to natural weathering and aging, these aesthetic imperfections will become increasingly visible.  There are, however, distinct benefits to this aspect of modified bitumen membranes.  Some manufacturing defects, such as poor surfacing embedment and uneven or insufficient backside coating, may be detected through an inspection of the rolls prior to installation.  Serious errors in application will be apparent almost immediately allowing timely remedial action to take place.
   
The decision to repair a modified bitumen roof should, as with every type of roofing system, be made only after careful thought and should be based primarily on performance consequences.  Open seams, fishmouths at laps, large unbonded areas of the membrane and areas where overheating has resulted in distortion to the reinforcing should be corrected as soon as possible.  Trivial anomalies, on the other hand, such as minor wrinkling and ridging are to be expected as a function of the physical characteristics of these materials and their required application methods.  Patching a minor blister or a small wrinkle because of visual impact alone is not justified and, in most cases, the repairs will look far worse than the blemish they were intended to correct.
   
As contractors have become more experienced with modified bitumen membrane installation, application techniques have evolved that have proven to reduce the occurrence and severity of these &#8220;blemishes&#8221;.  These techniques, however, will not eliminate these minor anomalies entirely.  In addition, it should be realized that they may significantly increase the cost of a roofing project due to added labour costs and lengthened construction schedules, with only marginal benefits for the owner and no meaningful increase in performance value.
   
Modified bitumen membranes have proven to provide satisfactory performance in most regions of our country.  As with any product, however, they have their limitations.  One should not forget that their primary purpose is to be a barrier to moisture.  Although they are available in a variety of coloured surfaces and textures, their inherent physical properties make an absolute flawless appearance impossible under most circumstances.  A reasonable level of expectation is required by those who specify these membranes together with a reasonable level of care and skill in their application.

=== 3.2 GENERAL ===

==== 3.2.1 Application ====
<jstdiv group="ref">As with all flexible membranes, the quality of the installation is critical to the performance of bituminous and modified bituminous membranes.  Although some of the application techniques for these membranes can be similar to those employed in built-up roofing, and the materials can be &#8220;familiar&#8221;, the differences are critical.</jstdiv> <jstdiv group="rec">It is important that the specifications, details, and installation techniques all conform to the membrane manufacturer's requirements.</jstdiv>

<jstdiv group="ref">One of the major concerns when applying these membranes with hot asphalt is to ensure the asphalt remains hot enough to fuse with the binder of the membrane.</jstdiv>   The asphalt temperature must conform to the membrane manufacturer's minimum application temperature and minimum +205&#176;C (+400&#176;F) as required by <i>RGC Guarantee Standards</i>.  Asphalt should not be mopped more than 1 m (3') preceding the roll as it has been demonstrated that the temperature of mopped asphalt drops sharply once mopped out (see Section 3.9.1.2).  <jstdiv group="rec">In addition to asphalt temperature, particular attention should be paid to slope limitations, fastening requirements, type of asphalt, the amount of asphalt used, and membrane flashing requirements when using hot asphalt.</jstdiv>  <jstdiv group="ref">Some manufacturers may require &#8220;torched&#8221; membrane flashings to ensure a proper bond and prevent problems with slippage or asphalt running down the vertical and collecting at the cant.  Slippage can also be a problem when an excessive amount of asphalt is used.  Only enough asphalt to meet the adhesive requirements is needed.  The mopping asphalt has a lower softening point than the bitumen in the membrane and may result in asphalt running and slippage problems.</jstdiv> 

<jstdiv group="rec">The major concern when installing &#8220;torch-on&#8221; membranes is an obvious one:  SAFETY.  This is discussed in detail in Section 5.0.1 <i>Safety Precautions - Torching</i>.  In addition to safety, it is essential that the membrane be fully and evenly bonded to the substrate.  As the roll is installed, the roofer must ensure the full width of the roll is melted and the preceding roll's side lap is preheated.  A small &#8220;wave&#8221; or &#8220;bead&#8221; of melted bitumen in front of the roll usually indicates sufficient heat.  Special attention to seams is required.</jstdiv>

<jstdiv group="ref">The polyester fabric used as reinforcing in many thermofusible (&#8220;torch on&#8221;) membranes is subject to dimensional changes at high temperatures.  Care must be exercised by the applicator not to over-torch or over-heat membranes.  Membranes must be designed and manufactured specifically for torch applications.</jstdiv><jstdiv group="rec">It is <b>recommended</b> that the cap sheet installation immediately follow base sheet installation in all cases.  However, when it may be necessary to delay the installation of the cap sheet due to weather, project scheduling or the like, then the following criteria must be considered:

* <b>ANY</b> delay in the installation of a cap sheet will result in the requirement for a special inspection and thorough cleaning of the base sheet.  The inspection is for mechanical damage from traffic or trades and cleaning is necessary to ensure good adhesion; this must be done to the satisfaction of the roofing contractor.
* Sanded base sheets should have a thin squeegee glaze coat of asphalt applied immediately after application of base sheet <b>if any delay for cap installation is anticipated.</b>
* Base sheets which are either sanded, glaze coated or thermofusible can be exposed for up to six months.  It must be recognized that an exposed base sheet is vulnerable to mechanical damage and construction dirt.  The base sheet should be well protected by carefully placed and maintained protection panels (plywood for example).  This protection would be supplied, installed and removed by someone other than the roofing contractor.
   
Consult manufacturer(s) for specific construction details and specifications.</jstdiv>

===== 3.2.1.1 APPLICATION CAUTION =====

====== MODIFIED BITUMEN MEMBRANES IN HOT MOPPED ASPHALT ======
# The design authority should recognize that the appearance of wrinkling and ridging in modified bitumen cap sheets applied in hot asphalt <u>may</u> be generic to certain manufacturers of this system, and particularly when attempted in cooler temperatures.  Although some manufacturers' literature suggests application may take place in temperatures as low as -25&#176;C (-13&#176;F), there are many subsequent limitations, the variables of which may result occasionally in severe wrinkling or ridging of the cap sheet as well as potentially poor adhesion.# RGC <b>recommends</b> that, in order to minimize the potential for wrinkling and ridging, the use of <b>mopped</b> cap sheets <b>not be considered</b> or specified when ambient temperatures (including wind chill) may go below +5&#176;C (+41&#176;F).
# Many factors affect the behaviour of the finished prefabricated sheets including:
#* The quality of the binder (waterproofing agent).
#* The choice of carrier including suppliers of fibreglass, polyester, or a combination of the two.
#* Saturation of the carrier.
#* Engineering of the sheet (composition and placement of the components within the sheet).
#* Quality control of the manufacturer.
#* Expertise of the manufacturer's personnel (including field representation).
#* Recommendations as to what is required for a completed system and the recommended application procedure.
#* Installation in the field by a <b>competent</b> contractor.
#* The designer's role in choosing the product(s) which satisfy each previous item described.
# The wrinkles or ridges are usually considered an aesthetic problem only, but may occasionally result in fishmouthing and intermittent bonding of the cap sheet.  Both of these deficiencies affect the performance of the membrane.
# RGC <b>recommends</b> the use of <b>torch applied</b> thermofusible cap sheets in 2-ply modified bitumen systems <b>in all cases</b>, but particularly if roofing must be carried out in cool or cold weather.  Appropriate safety precautions regarding torching must be addressed.
# Occasionally some mopped systems, particularly with heavy cap sheets, have exhibited a propensity for membrane slippage, frequently on insulated systems where there is a combination of slope, heavy inter-ply mopping and lack of mechanical fastening (back nailing) of sheets.  (See Section 2.1.3, C5.3 for mechanical fastening requirements and slope limitations).
# It is also common for <b>mopped</b> systems to exhibit some asphalt bleed-out at the seams.  Minimal or reasonable bleed-out is to be expected and is an aesthetic problem which may be minimized by the embedment of matching granules.  Bleed-out which oxidizes and alligators with time does not normally affect the waterproofing efficiency of the roof.

====== APP MODIFIED BITUMEN MEMBRANES ======
# Cold Weather Application:
#:Designers and contractors should recognize that APP modified bitumen membranes can be extremely difficult to work with in colder temperatures, and that even attempting to unroll the material in very cold temperatures may result in cracking of the sheet or other problems.
#:<br>
#:Some manufacturers make different grades of material for application at different times of the year.  Most manufacturers recommend an application temperature <b>lower limit</b> of approximately 5&#176;C (40&#176;F). <b>DO NOT ATTEMPT</b> to install APP modified bitumen membranes below these recommended temperatures.

==== 3.2.2 Roof Slope ====
On all reroofs without positive slope to drain and all protected or modified protected membrane roofing, only non-organic felts or membranes may be used.

Positive slope to drain is an absolute requirement for organic felts. All new construction roofs must have positive slope to drain. Definition of roof slope is provided in Section (reference here).  Where required, crickets and saddles should be provided to assist drainage.

<jstdiv group="policies">For single-ply roof systems, a minimum slope 1:15 (3/4" in 12")is required. Any roof areas less than 1:15 (3/4" in 12") require 2 ply membrane assemblies.</jstdiv>

<jstdiv group="rec">A minimum slope of 1:50 (l/4" in 12") is strongly recommended, and should provide positive slope to drain [required for a Five (5) or Ten (10) year RoofStar Guarantee for new construction and for organic felt membrane systems when re-reroofing]. Positive slope to drain is attained when no standing water remains on the deck within a reasonable amount of time after rainfall stops during days with conditions that permit evaporation.

Slope can be provided by sloping the deck, or using tapered insulation boards of insulating fill (insulating fill is rarely used in B.C.). A minimum slope of 1:50 (1/4” in 12”) is strongly recommended. The exception is often drain wells that are designed to collect water and provide a flat surface for the installation of roof drains. Therefore standing water may remain in drain wells for a longer period after a rainfall stops.

Crickets and saddles should be employed between drains where the design slope of the roof is less than 1:50 (1/4" in 12"), where the roof deck is uneven and ponding may occur, or simply to assist the movement of water to drains.

In re-roof applications, when utilizing 2 ply modified asphalt membranes, there is no requirement for slope to drain. However, slope is strongly recommended.</jstdiv>

====== SUGGESTED REVISION ======

All newly constructed roofs must have positive slope to drain.

<jstdiv group="rec">In re-roof applications, when utilizing 2 ply modified asphalt membranes, there is no requirement for slope to drain. However, a minimum slope of 1:50 (l/4" in 12") is strongly recommended for any low-slope roof, and should provide positive slope to drains.</jstdiv>

For single-ply roof systems, a minimum slope 1:15 (3/4" in 12") is required. Any roof areas sloped less than 1:15 (3/4" in 12") require 2 ply membrane assemblies.

<jstdiv group="ref">''Positive slope'' in this Manual means a slope that drains water sufficiently so that no standing water remains on the deck within a reasonable amount of time after rainfall stops, during days with conditions that permit evaporation.  A roof is said to have ''positive slope'' even if standing water remains in drain wells for a longer period after a rainfall stops; drain wells are designed to collect water and provide a flat surface for the installation of roof drains.

Slope can be provided by sloping the deck, or using tapered insulation boards of insulating fill (insulating fill is rarely used in B.C.).</jstdiv>

<jstdiv group="rec">Crickets and saddles should be employed between drains where the design slope of the roof is less than 1:50 (1/4" in 12"), where the roof deck is uneven and ponding may occur, or simply to assist the movement of water to drains.</jstdiv>

==== 3.2.3 Re-Roofing ====
<jstdiv group="policies">Re-roofing over existing membrane is only permitted in specific circumstances and only when approved in writing by RGC and the membrane manufacturer.</jstdiv>

==== 3.2.4 Tying Into Existing Roofing ====
Where a new roof is tied-in to an existing roof, the two areas must be isolated and separated by a curb joint properly attached to the structure and properly flashed. If job conditions do not allow for a curb joint, written permission from RGC to eliminate curb joints must be obtained and a positive water cut-off must be installed to the deck to isolate the existing roof from the new roof.

==== 3.2.5 Wall Sheathing: Perimeter Requirements (EDITED for format and content) ====
<jstdiv group="policies">Regardless of the substrate to which roof membranes are applied, installation of roof membrane to the surface must be governed by the membrane manufacturer's requirements for that substrate.</jstdiv>

====== GYPSUM SUBSTRATES ======
Gypsum boards on vertical surfaces must be RGC Accepted overlay boards with water resistant properties.

<jstdiv group="ref">On steel framed walls, it is acceptable to use gypsum overlay boards accepted for the Guarantee Program, provided the gypsum board has a minimum thickness of 12mm (1/2") or fibre-mat reinforced cement boards with a minimum thickness of 9.5 mm (3/8") that conform to ASTM C1325-04.</jstdiv>

<jstdiv group="policies"></jstdiv>

====== DECK SUPPORTED BY WALL ======
In combustible construction, or where permitted by the Building Code in non-combustible construction, all concrete or masonry parapets or walls which do not provide a smooth, clean, dry surface for membrane adhesion or are to be applied with oxidized asphalt as the adhesive must be sheathed with a minimum 15.9 mm (5/8") treated plywood, or 9.5 mm (3/8") reinforced cement board that conforms to ASTM C1325-04 mechanically attached to the wall. The plywood is to extend either a minimum of 200 mm (8") above membrane surfacing, to the bottom of the reglet, or, if required by the type of membrane, to the full height of the parapet.

====== DECK NOT SUPPORTED BY WALL ======
Where permitted by the Building Code, all concrete or masonry parapets or walls to which roofing is to be applied must be sheathed with minimum 15.9 mm (5/8") plywood or 9.5 mm (3/8") reinforced cement board that conforms to ASTM C1325-04 solidly attached to the roof deck with adequately treated blocking. Compressible insulation is to be installed between the sheathing and the wall. Coping and / or counter flashing is to be installed. See construction details Sections 10.3.1 and 10.3.3. The plywood is to extend either a minimum of 200 mm (8") above membrane surfacing or, if required by the type of membrane, to the full height of the parapet or wall. This item is supplied and installed by others unless specified otherwise.

All wood decks shall be properly fastened to B.C.Building Code requirements. With the exception of standard insulated roof systems, all knots or cracks shall be covered with metal prior to acceptance of deck surface.This work is to be done by others.  <jstdiv group="policies">Non-veneer (O.S.B. or wafer board) panels are acceptable sheathing for decks with low-slope roofing applications, provided the roofing membrane is not fully adhered directly to the panels.</jstdiv>  The minimum plywood or non-veneer (O.S.B or wafer board) deck thickness for low-slope roofing (i.e., membrane roofing) shall be a minimum 12.7 mm (1/2")and as indicated in the applicable Building Code.

An RGC approved separation sheet, minimum#40 asphalt coated fibre glass base sheet conforming to CAN/ CSA A123.16 - M88 (R1996), Type II or manufacturer’s accepted base sheet of equal or greater weight and reinforcement, or RGC accepted rigid insulation / overlay board mechanically attached or semi-adhered membrane (spot or strips) is required over non-veneer panels before fully adhered roofing membrane is applied.

<jstdiv group="policies">Direct torch (open flame) membrane applications to wood decks and wood surfaces is NOT permitted. For further development of this policy, refer to SBS Application & Safety: Best Practices.</jstdiv> 

Differential edge movements or deflection in excess of1/360 of the span in plywood or non-veneer decks in low slope roofing must be prevented by: 
* solid blocking under non-supported edges, and /or 
* use of tongue-and-groove plywood with non-grooved edges supported by joists or solid blocking, and / or

==== 3.3.3 Separation Layers ====
Pre-cast panels, post-stressed beams, or “T” and cavity decks shall have a separation layer such as fibre board, gypsum board, plywood, proprietary overlay board etc. applied over the deck prior to the application of the roof membrane. Where a difference exists in the levels of adjacent surfaces, the general contractor or others shall install grouting. This grouting shall be feathered on the lower surface a minimum distance of twelve times the amount of the vertical differential.

==== 3.3.4 Electrical Conduit ====
Conduit, EMT, cable and/or piping applied on the top of roof deck surfaces shall not be acceptable on new construction projects. <jstdiv group="policies">If conduit is present on decks in re-roofing projects, the deck must be made smooth and even to the satisfaction of the accepted roof inspection firm. The upper layer of insulation must cover the conduit, EMT, able and/or piping.</jstdiv>

=== 3.4 VAPOUR RETARDERS ===
<jstdiv group="policies">The decision to use and the selection of, a vapour retarder is the responsibility of the design authority.  Neither RGC nor the roofing contractor will accept any responsibility for damage to, or failure of, the roof system caused by the use or absence of a vapour retarder.</jstdiv>

=== 3.5 INSULATION ===

==== 3.5.1 General ====
Only RGC Accepted insulations, specifically listed by membrane manufacturers in the RPM as acceptable for use with their modified bituminous loose laid, or mechanically attached base sheets, may be used without an overlay board in the RGC Guarantee Program. 

==== 3.5.2 Layering ====
Multi Layering: All square edge flat format insulation boards greater than 67.5mm (2.7”) in thickness shall be installed in multiple layers. Multi layering of plastic foam insulation is required for all adhered, mechanically attached, and ballasted low slope roof assemblies. In addition, all slope format plastic foam insulation boards greater than 150mm (6”) in thickness shall be installed in multiple staggered layers or alternatively, be installed under two (2)offset/staggered layers of RGC accepted insulation overlay boards. 

Insulation board joints are to be offset or staggered 300 mm (12") from adjacent layers and rows.

<jstdiv group="policies">A minus offset tolerance of 50 mm (2") maximum will be permitted to compensate for variance in manufactured tolerance of differing insulation board widths and lengths. The exception is sloped insulation boards that are generally installed soldiered fashion to adjacent rows; and the first layer of overlay board over heat sensitive insulation to facilitate joint taping.</jstdiv>

==== 3.5.3 Nailing Strips ====
Required on Slopes exceeding 1:12 [1" in 12"]) 
Where the total insulation thickness on nailable decks exceeds 25 mm (1"), nailing strips shall be mandatory on all insulated exposed membrane roofs utilizing bitumen as an adhesive and / or waterproofing medium (BUR, single or multi-ply modified bitumen or oxidized asphalt sheet systems (mop or torch applied base sheets,non-conventional felts, etc.) and will be supplied and installed by the roofing contractor.

==== 3.5.4 Mechanical Fastening ====
When conventionally adhered roof assemblies are installed, (adhered, hot asphalt mopped, torched, etc.), all insulation must be mechanically fastened to all nailable decks including steel, with exceptions as per (reference here).  <jstdiv group="ref">The upper layer or overlay in a multiple-layer insulation application does not require mechanical fastening.</jstdiv>  The exception is for slopes exceeding 1:12 (1" in 12") or steeper - in those cases, the upper layer must be fastened.

When using multiple layers of plastic foam insulation the layers shall be mechanically fastened, whenever possible, as if they are a single layer. Alternately, when the use of mechanical fasteners is not feasible, or multiple layered assemblies require mechanical fastening of the base layer only, or decks are constructed of non-nailable materials (concrete,) polyurethane foam adhesives may be utilized to adhere insulation layers to one another, to other insulations, or substrates. Only polyurethane foam adhesives that are specifically listed as acceptable by the insulation manufacturer may be used. Extruded polystyrene insulation must have planed faces (removal of smooth surface) when adhered with polyurethane foam adhesive.

<jstdiv group="ref">The roof area is divided into three areas (zones). The perimeter area is defined as 10% of the building width or 40% of the building height, whichever is less. In no case will perimeter area be less than 2.0 m (7'). The field area is defined as the remaining area after the perimeter is calculated. When the roof height is:• greater than 18 m (60’) and low-slope (slope is 2:12 or less) or• less than 18 m (60’) and pitched (slope is greater than 2:12), Perimeter fastening along the entire eave will be enhanced to corner requirements. The corner area is defined by the perimeter in both directions at the corners.</jstdiv>  <jstdiv group="policies">In no case will the corner area be less than 2.0 m x 2.0 m (7’ x7’).</jstdiv>

<jstdiv group="ref">For corner enhancement of roofs in high wind locations (higher than 100 mph) or for roofs above 60’ refer to Section (reference here).

Mechanically attached insulated membrane systems may be fastened according to manufacturer’s tested specifications complying with CSA A123.21-10 or a FM 1-90 assembly wind rating and when accepted by RGC and conforming to A4.6. Factory Mutual adhered assemblies require the initial layer to be mechanically fastened over a steel deck.

The upper layer or overlay in a multiple-layer insulation application does not require mechanical fastening.</jstdiv>

If mechanical fastening to concrete decking is required proprietary concrete fasteners and plates must be used.

<jstdiv group="policies">New construction projects must follow proper sequencing. Where roof flashings overlap work by others (i.e. siding, stucco, etc.), this work must be complete prior to the installation of metal flashing or wood blocking must be installed to facilitate the future installation of the exterior wall finish under the cap flashing. When lapping under work by others (siding, stucco, etc.), the membrane and metal roof flashings must be installed prior to any wall coverings. Any variance to proper detail sequencing must be approved by the design authority in writing (see Section 10.3.3).

A reverse lap application method for base sheet and base sheet flashing (stripping), at roof up stand transitions, is permitted when self-adhered base sheet flashing is used as flame protection for wood surfaces. Use of the reverse lap method must be an acceptable application method to the membrane manufacturer.

If no published instructions are available, specific instructions in writing from the manufacturer must be obtained and filed with RGC before project start-up.

=== 3.10 PERIMETER FLASHINGS: METAL ===

==== 3.10.1 General ====

All roof protrusion and penetration flashings, vents, curbs, sleepers, pipes cable, drains, etc. shall NOT be installed LESS than 200mm (8") from the base of walls, cants, eaves and other roof equipment, protrusion and penetration flashings.

Metal base flashing shall be kept approximately 25 mm (1") above gravel to prevent immersion in water with the exception of protected and modified protected roof systems. (Question: is this relevant to SBS roof systems Standards?).  

<jstdiv group="policies">Gravel stop-type flashings may be used, provided manufacturer's printed instructions are followed (see Section reference, if required).</jstdiv><jstdiv group="ref">The exceptions are overflow drains and roof scuppers that are installed through walls. These items are to be located by others.

Sheet metal flashings are designed to divert water away from the membrane flashing termination, usually onto the roof. The metal flashing also protects the membrane from deterioration due to the elements and from mechanical damage. The metal flashing is not a waterproofing membrane, therefore the roofing membrane should be continuous under the metal (see details Section 10.3 and RGC Guarantee Standards for requirements). 

Metal flashing is essential to complete most waterproofing and roofing applications and attention to detail is critical. Some basic rules to observe when designing or installing metal flashings are: 
* only “S-lock” or “standing seams” are permitted (see Section 10.2.1) 
* metal counter flashings always go on top of the completed roof membrane 
* limit metal flashing lengths to 3.04 m (10' ) 
* extend base flashings down over membrane flashing at cants to minimum 25 mm (1") above roof membrane surface. (Not applicable to protected membrane roof assemblies.)

==== 3.10.3 Attachment ====

The use of concealed in-seam fasteners is required. Any fastening of metal flashings on the top of parapet surfaces is strongly discouraged and is not permitted as the only attachment method. 

If top-surface fastening must be used because of a specific job site condition, only appropriate screw-type fasteners with neoprene washers may be used. Nails are not acceptable. The outside and inside face of metal cap flashing must be attached with cladding fasteners (screws), and/or concealed clips. Continuous and discontinuous concealed clips and or cladding screw fasteners or a combination of these attachment methods are acceptable to secure metal cap flashing. No fastening of flashing is permitted within 87.7 mm (3-1/2") of the roof surface. Note: Cladding fasteners or concealed clips are not required on the inside face of roof edge cant strip details.
 
Cladding fasteners (screws) with gasketed washers, used as exposed fasteners for metal flashing, must be No. 8 or better, made of metal compatible with and corresponding in colour to, the flashing material being installed. Nails are not acceptable as exposed fasteners. The minimum number of cladding screws used to face fasten metal cap flashing shall be three (3) fasteners equally spaced (±10%) between seams of flashing formed from 3000 mm (10 ft.) metal stock and a minimum of two fasteners equally spaced (±10%) between flashing seams formed from 2400 mm (8 ft.) metal stock.

When cants are not used on curbs standard seaming practices (standing seams) shall be followed, with the exception of the vertical flashing portion that is lapped to fit under counter flashing or equipment flanges.

<jstdiv group="policies">For roof curb-flashing seams ( e.g. equipment, skylights, etc.), which do not exceed 300 mm (12") in height, lap-type seams may be used on the vertical portion provided standing seams are used in the cant area.</jstdiv>

The design authority shall choose and specify the seaming system.

==== 3.10.6 Cap Flashings, Base Flashings and Reglets ====

The top surface of walls (parapets, expansion joints, firewalls, roof dividers, etc.) wider than 100 mm (4" nominal) shall be constructed to provide positive slope to drain and be covered with metal cap flashing. Provide a reglet for all flashings terminating in concrete or masonry walls. When wall flashing terminates in a reglet, typically on high parapet walls, a coping flashing is required at the top of the parapet wall (See Metal Flashing Details; Section Reference needed). On new construction projects reglet and sloped wood blocking at top surface of concrete or masonry walls are to be installed by others (see Section 10.3.3).

<jstdiv group="policies">On flexible membrane conventional roofing systems, when metal wall or curb base flashings are not specified, RGC and manufacturer's approved wall or curb stripping membranes are acceptable when used with a secondary metal counter flashing placed a maximum of 250 mm (10") above the surface of the roof assembly. Stucco stops are not considered secondary metal counter flashings (see Section 10.3.3).</jstdiv>

Metal base flashings are required on all walls and curbs on roof systems that utilize gravel ballast filter mats. Metal base flashings on protected and modified protected membrane roofs must “kick out” minimum 50 mm (2") over insulation and filter fabric. (See note Section 10.1.1).

</tab>
<tab name="Information: Composite Board Insulation">
Composite board roof insulation products consist of an insulation bonded with another insulation and / or a variety of other products (typically fibreboard, perlite, membranes, etc.) to form a unified, multi-layered insulation board. The top and bottom surfaces of the board may be impregnated and / or coated with asphalt (or other binders), and covered with facing materials such as roofing felts, foils, kraft paper modified bituminous membranes, etc.

The properties and performance of composite board roof insulation varies with the components of the board. Generally, the boards are manufactured to provide some of the following properties and advantages:

* Compatible with asphalt,
* Resistant to thermal conductivity,
* Resistant to fire,
* Resistant to the effects of moisture,
* Resistant to cell deterioration (durable),
* Resistant to impact, and / or
* Unaffected by asphalt application temperatures (no overlay may be required).

The possible disadvantages and precautions involved in the use of composite board insulations include:

* Complexity of manufacture and dissimilar materials,
* Sometimes expensive, and
* Limited availability

</tab>
<tab name="Information: XPS Insulation">
(See also <i>Expanded Polystyrene Foam</i> and <i>Protected Membrane Roof Assemblies</i>)

Molten polystyrene and a blowing agent HCFC (142B) are mixed, under pressure, in an extruder. As this solution is extruded through an orifice into ambient temperature and controlled conditions, the blowing agent vapourizes causing the polystyrene to expand approximately 30 times its original size. The continuous extrusion process produces boards with a surface &#8220;skin&#8221; and closed cell structure and, for this reason, has been used extensively for protected membrane roof assemblies. The rigid insulation boards are expanded to a specific thickness during manufacture and have an approximate density of 32 kg / cu. m (2 lb / cu.ft).

Extruded expanded polystyrene foam roof insulation is combustible and, when used on steel decks or over a roof that is subject to fire exposure from below, a fire-rated underlayment or thermal barrier (such as gypsum board) may be required between the roof deck and the insulation (consult Building Code and insurance requirements).

Extruded expanded polystyrene roof insulation is manufactured to CAN / ULC-S701 standard and is currently available in three types (depending on physical properties) and in four forms, as follows:
* Type 4 for use on conventional or protected membrane roofing systems
* Type 4 with a factory-applied latex-modified concrete topping for protected membrane roofing systems
* Type 3 for use on conventional roof systems
* Type 2 for use on conventional roofing systems [density of 24 kg / cu.m (1.5 lb / cu.ft)]

Extruded polystyrene roof insulation provides the following properties and advantages:
* Compatible with asphalt
* Resistant to the effects of moisture
* Resistant to cell deterioration (durable)
* Resistant to impact
* Resistant to thermal conductivity
* Stable K-value

The possible disadvantages or precautions involved in the use of extruded polystyrene roof insulation include:
* Flammable (combustible)
* Affected by solvents (i.e. adhesives and cleaners used for single ply membranes)
* Heat sensitive [requires an insulation overlay, such as fibreboard, to prevent &#8220;melting&#8221; (burnouts) from hot asphalt]
* Will not retain nails (requires screws and plates)
* Dimensional instability may result from improper curing at the factory

<i>Product Group:</i> <b>CONCRETE TOPPED INSULATION ROOF PANELS FOR USE IN PROTECTED MEMBRANE ROOF ASSEMBLIES</b>

<i>Country of Origin:</i> CANADA<i>Country of Manufacture:</i> Canada, 1983

<u>DESCRIPTION</u>

The roofing assembly / material information published in the <b><i>RCABC Roofing Practices Manual</i></b> does NOT represent a complete set of the manufacturer's published data, nor does it represent a detailed specification. The preparation of a detailed specification is the responsibility of the design authority.

Tech-Crete&#8482; insulated roof panels are 600 mm (2 ft. X 4 ft) composite panels of extruded, expanded, Type 4 CAN/ULC-S701-97 / CGSB-51.20-M87 polystyrene foam, with a factory applied 9.5mm (3/8&#8221;) latex modified concrete topping. They are designed as lightweight, self-ballasted, interlocking insulated panels for loose application on top of well drained roof membranes in a low-slope, protected membrane roof assembly.

Tech-Crete panels are tongue and grooved on the longitudinal sides, with a butt edge on the lateral ends. Each board weighs minimum 16.3 kg (36 lb.) creating an insulated panel assembly of about 22 kg/m&#178; (4.5 lb/ft&#178;. Panels are available in standard thickness of 50 mm (2&#8221;) and 100 mm (4&#8221;). In addition, 75 mm (3&#8221;) thick panels are available as special order.

<u>BASE INSULATION</u>

The base insulation is Dow Roofmate*, a superior moisture resistant material (absorption less than 1%) with a high thermal resistance value of 0.88 (R 5.0 per inch.), and high compressive strength of 240 kPa (35 psi).

<u>CONCRETE TOPPING</u>
The latex modified concrete topping is available in two standard colours, both with a relatively smooth surface:
* CTI (Concrete Topped) Insulated Roof Panels are manufactured as a standard concrete grey colour.
* SRI (Solar Reflective) Insulated Roof Panels are manufactured with a full depth white concrete topping.

<u>PERFORMANCE</u>

Latex modified concrete is very durable and chemically resistant. It can be cut with a masonry saw.
* Concrete topped insulation roof panels can accept occasional maintenance foot traffic, however, they are not intended for use as a patio, plaza deck or construction platform.
* As with other cementitious products, concrete topped insulation roof panels can become stained by efflorescence if stored unprotected for extended periods. This efflorescence will not be so obvious on SRI panels, however, care in scheduling and handling is required to ensure the white topping remains clean.
* Concrete topped insulation roof panels are compatible with most commonly used membranes, however, in some cases a slip sheet between membrane and insulation is required to minimize cracking of the concrete topping.

<u>CERTIFICATIONS AND APPROVALS</u>

Complies with the following codes:
* CCMC - Evaluation Listing #04888-L
* CAN/ULC S107, Type 4 - standard for Thermal Insulation Polystyrene Boards.
* CAN/ULC S107-03 Methods of Fire Tests of Roof Coverings

(See also 3.6.5 <i>Expanded Extruded Polystyrene</i>)

<i> Third Party Certification</i>: RGC welcomes and accepts the industry recommendation presented by all EPS manufacturers currently active in the B.C. market to require third party certification of the EPS products meeting CAN / ULC-S701-97 / (CAN / CGSB-51.20-M87) requirements. It is understood that such a certification program requires annual inspections / recertification by an independent testing lab.

Molten polystyrene and a blowing agent are mixed and formed into uniform closed-cell structures (&#8220;beads&#8221;). These are later expanded up to 40 times by steam in a pre-expander. (The amount of expansion determines the density and, therefore, the thermal conductivity of the final product.) The expanded beads are stabilized in curing bins, fused into a billet in a block mold, and cut into the desired size, shape and thickness. This process produces rigid boards of interconnecting closed cells of densities varying from 16 to 48 kg / cu.m (1 to 3 lb / cu.ft). Expanded polystyrene insulation is commonly referred to as &#8220;beadboard&#8221; or &#8220;popcorn&#8221;.

Expanded polystyrene roof insulation is presently manufactured to the CAN / ULC-S701-97 / (CAN / CGSB-51.20-M87) standard and is available in four types, depending on the physical properties of the material. Basically, the strength (tensile, compressive, flexural, and shear) and thermal resistance properties increase, and the water vapour permeance and water absorption properties decrease from Type 1 to Type 4. (For Type 2 and Type 4 see also Section 3.6.5 <i>Extruded Expanded Polystyrene</i>). <b>Note:</b> Type 4 is usually, if not always, extruded.

Expanded polystyrene foam roof insulation is combustible and, when used on steel decks or over a roof that is subject to fire exposure from below, a fire-rated underlayment or thermal barrier (such as gypsum board) may be required between the roof deck and the insulation (consult Building Code and insurance requirements).

Expanded polystyrene foam roof insulation provides the following properties and advantages:
* Compatible with asphalt
* Resistant to the effects of moisture
* Resistant to cell deterioration (durable)
* Resistant to impact
* Resistant to thermal conductivity
* Stable K-value (the thermal conductivity does not change with aging)

The possible disadvantages or precautions involved in the use of expanded polystyrene roof insulation include:
* Flammable (combustible)
* Affected by solvents (i.e. adhesives and cleaners used for single-ply membranes)
* Heat sensitive [requires an insulation overlay (such as fibreboard) to prevent &#8220;burnouts&#8221; from hot asphalt]
* Will not retain nails (requires screws and plates)
* Dimensional instability may result from improper curing at the factory.

<u>PLASTISPAN SLOPED INSULATION</u>

The complete family of PlastiSpan insulation materials is available in both flat and sloped profiles. All roofing experts agree that adding a slope to the top surface of the roof assembly, however small, will provide positive drainage, eliminate pooled water, and can extend the life of the roof assembly. For sloped roofs, Plasti-Fab provides PlastiSpan insulation cut with a taper across the 1.2-rn (48") width. A predetermined layout of the tapered insulation boards is provided by Plasti-Fab in order to include a 1:50 (1/4" in 12") or 1:100 (1/8" in 12") positive slope to the drains.

Special sizes, &#8220;crickets&#8221;, and back slopes are available; custom computerized design of PlastiSpan sloped insulation boards layout is provided.

<tab name="Manufacturers and Products">

</tab>
<tab name="Information: Polyisocyanurate">
Polyisocyanurate is a closed-cell rigid foam material. The insulation boards are manufactured with asphalt-saturated felt, glass fibre or acrylic facer sheets on the top or bottom of the foam core. In some cases the foam core is reinforced with glass fibre or acrylic to provide additional fire resistance and greater dimensional stability.

Polyisocyanurate foamboard roof insulation is presently manufactured to two standards:

* <u>CAN / ULC S704-01 (CGSB 51-GP-21M)</u> applies to unfaced polyisocyanurate rigid insulation boards intended for applications where the continuous use surface temperature does not exceed +110&#176;C (+230&#176;F). This standard establishes one type (Type 4) and three classes (Class 1, 2 or 3) of polyisocyanurate insulation. The type is determined by the physical properties of the material and the class is determined by its surface burning characteristics.

* <u>CAN / ULC S704-01 (CAN / CGSB-51.26-M86)</u> applies to faced polyisocyanurate rigid insulation boards intended for applications where the continuous use temperature is within -60&#176;C to +80&#176;C (-76&#176;F to +176&#176;F). This standard establishes four types (Type 1, 2, 3, or 4), four facing categories (Facing 1, 2, 3, or 4), and two surface burning characteristic classifications (surface burning characteristic &#8220;a&#8221; or &#8220;b&#8221;). The type is determined by the physical properties of the material, the facing is determined by the product the insulation is foamed between, and the surface burning characteristic is derived from the final product's flame spread classification. <i>RGC Guarantee Standards</i> require that polyisocyanurate insulation manufacturers clearly identify the manufacturing date on product labels.

Polyisocyanurate insulation provides the following properties and advantages:
* Compatible with asphalt
* Compatible with roof system components
* Resistant to the effects of moisture
* Resistant to cell deterioration
* Resistant to impact
* Resistant to thermal conductivity
* Resistant to fire
* Resistant to thermal cycling (dimensionally stable)
* Unaffected by hot asphalt
* Retains mechanical fasteners

The possible disadvantages or precautions involved in the use of polyisocyanurate foam insulation include:
* Requires an insulation overlay (fibreboard or retrofit board) to prevent potential asphalt blistering
* Aged thermal resistance Long Term Thermal Resistance (LTTR) tested to CAN / ULC -S770 should be used for design calculations. Refer to RPM Section 3.6.1.1 quick reference chart for thermal resistance values.
* Felt skin may change dimensionally if exposed to weathering (provide protection prior to installation)
* Heavy equipment may compress insulation, causing deflections and de-bonding of the membrane
* Will not retain nails (requires screws and plates)

===== 4.3.5 Fibreboard Roof Insulation =====
<tabs>
<tab name="Manufacturers and Products">
Click on any one of the tabs to the right to find products by manufacturer
</tab>
<tab name="Information: Fibreboard Insulation">
Fibreboard insulation is composed of wood, cane, or other vegetable fibres and waterproofing binders. A water slurry containing the wood fibres and waterproofing binders is deposited onto a moving screen. The water drains through the screen and the remaining mass is heated in an oven or dryer to produce the finished product. Fibreboard roof insulation is produced in several forms:

* Plain
* Impregnated with asphalt or petroleum based paraffin
* Coated with asphalt

Fibreboard Roof Insulation that is adhered in a roof assembly with hot asphalt or asphaltic-based adhesives <u>must</u> have an asphalt coating on the top and bottom surfaces (minimum coated two sides) to meet RGC Guarantee Standards. Fibreboard for use as roofing insulation is manufactured to meet or exceed the requirements of CAN / ULC-S706 (Insulating Fibreboard), Type I (Roof Board).

Fibreboard roof insulation provides the following properties and advantages:
* Compatible with asphalt
* Compatible with most roof system components
* Resistant to thermal conductivity
* Resistant to cell deterioration (durable)
* Resistant to impact
* Resistant to thermal cycling (dimensionally stable)
* Unaffected by asphalt application temperatures (no overlay required)
* Stable K-value (the thermal conductivity does not change with aging)
* Retains roofing nails

The possible disadvantages or precautions involved in the use of fibreboard insulation include:
* Flammable (Combustible)
* Absorbs moisture (protect from the effects of weathering)
* Low thermal values
* Organic in nature and will rot on exposure to moisture.

===== 4.3.6 Perlitic =====
<tabs>
<tab name="Manufacturers and Products">
Click on the tab to the right to find products by the listed manufacturer
</tab>
<tab name="Information: Perlitic Insulation">
Perlite ore is a volcanic glass with a natural water content characteristic. When this ore is heated to approximately +930<sup>o</sup>C (+1700<sup>o</sup>F) the water vaporizes and the ore expands into glass spheroids. The expanded perlite ore may be mixed into a water slurry formulation containing cellulose fibre, a small amount of asphalt, and sometimes starch. The slurry is then dried into boards and cut to size. The top surface is usually treated to minimize bitumen absorption.

Perlitic roof insulation provides the following properties and advantages:
* Compatible with asphalt
* Compatible with most roof system components
* Resistant to thermal conductivity
* Resistant to fire
* Resistant to impact
* Resistant to thermal cycling (dimensionally stable)
* Unaffected by asphalt application temperatures
* Stable K-value
* Retains roofing nails

The possible disadvantages or precautions involved in the use of perlitic roof insulation include:
* Absorbs moisture (protect from the effects of weathering)
* Heavy equipment may compress boards causing possible debonding of the insulation from the deck
* Extremely friable (crushable); proper compounding and correct grading is important
* Relatively low thermal values.

<u>FESCO BOARD</u>

Fesco Board is a homogeneous board composed of expanded perlite, a volcanic ore, blended with selected binders and fibers. The perlite particles are subjected to intense heat, which causes them to expand approximately fifteen times their original size. The resulting glass-like beads contain air cells, which provide high insulating efficiency.

The top surface of Fesco Board is sealed with Top-Loc coating to ensure positive adhesion of a built-up or modified bitumen membrane. The minimum recycled content is 25% by weight.

Fesco Board has excellent fire resistance and is approved for use in Factory Mutual approved constructions. When applied over rigid decks, Fesco Board&#8217;s high laminar tensile strength resists damage from on-the-job and maintenance traffic, offers an excellent substrate for all roofing membranes, and effectively bridges flute openings in metal decks. Because of its perlite composition and low water absorption rates, Fesco Board is dimensionally stable.

<u>DESCRIPTION</u>

The roofing assembly / material information published in the <b>RCABC <i>Roofing Practices Manual</i></b> does NOT represent a complete set of the manufacturer&#8217;s data or specifications. The preparation of a detailed specification is the responsibility of the design authority.

NVS and Insulcel are composite systems that combine the unique properties of Lightweight insulating concrete (LWIC) and premium expanded polystyrene (EPS) foam insulation. The polystyrene insulation board can be installed in thicknesses necessary for high insulation values and in a stair stepped fashion, facilitating a positive slope to drain.

Poured 25 mm (1") for NVS and 50 mm (2") for Insulcel thickness over EPS insulation, these LWIC systems have been engineered for use over non-slotted or slotted galvanized corrugated metal decks (Insulcel), structural concrtete substrates and, where appropriate, over existing roofs in recover applications. These systems provide high performance solutions to industry concerns that include moisture resistance, high compressive strength, dimensional stability, fire and wind resistance, stable R-values and environmental safety. As a reusable resource LWIC also provides LEED values and is re-roofable.

<u>PRODUCTS</u>

NVS concrete is a 1:3.5 volume ratio of Portland cement to patented NVS Concrete Aggregate.

INSULCEL concrete is a mixture of Insulcel-PB pregenerated cellular foam and Portland cement / water slurry.

</tab>
<tab name="Information: Insulation Coverboards">
Insulation overlays are used to separate the roof membrane from the primary insulation, usually for one of two reasons:

* to prevent the insulation from affecting the performance of the roof membrane
* to prevent the roof membrane and / or the method of application from affecting the insulation

The insulation can affect the performance of the roof membrane in the following ways:
* the insulation may be incompatible with the membrane, resulting in a loss of physical properties
* different coefficients of thermal expansion may result in membrane splits / cracks.

The roof membrane and / or the method of application can affect the insulation in the following ways:
* the insulation may not be capable of withstanding asphalt application temperatures and may &#8220;burn-out&#8221;
* some insulations will not accommodate direct torch-applied membranes
* insulations that are too &#8220;soft&#8221; may result in delamination or damage to the membrane or insulation when exposed to heavy loads or traffic
* the solvents and adhesives used for flexible membranes may adversely affect the insulation.

<b>NOTE</b>: All hot asphalt-adhered asphaltic membranes (built-up roofing, modified bitumen, etc.) require an insulation overlay over heat sensitive insulations and heat insensitive foamed insulation. <i>RGC</i> <i>Guarantee Standards</i> for heat sensitive insulations<b> require</b> a two-layer overlay board for a five (5) or ten (10) year Guarantee. RGC <b>requires</b> the use of a two-layer overlay board over heat sensitive insulations in all cases, and also <b>requires</b> a single-layer overlay board application over heat insensitive insulations for all hot asphalt-adhered membranes. For single-ply, non-asphaltic membrane roofing systems, the membrane manufacturer should be consulted for proprietary options.

<tab name="Information: SBS Membranes">
Styrene butadiene styrene (SBS) polymer modifiers are &#8220;thermoplastic elastomers&#8221;. They are elastomers, which behave similar to both thermoplastics and thermosets (or &#8220;elastomerics&#8221;). Thermoplastics soften with heat and harden when cooled, no cross-linking (vulcanization) of molecules occurs, and they tend to exhibit &#8220;plastic&#8221; properties. Thermosets are materials in which cross-linking of the molecules occurs and they tend to exhibit &#8220;elastomeric&#8221; or rubber-like properties.

Simply stated, flexible polybutadiene &#8220;chains&#8221; interconnect with the glass-like polystyrene &#8220;blocks&#8221; and, when cooled, the resulting network behaves as if the molecules were cross-linked. The process is repetitive in that the networks may be disrupted by heat or solvents but will reform upon cooling or removal of the solvents.

Bitumens modified with SBS can display improved physical and mechanical properties. The improved properties are only possible if the SBS polymer is properly dispersed within a suitable bitumen. A well dispersed, homogeneous polymer mixture will form a continuous rubber network throughout the bitumen.

SBS modification of bitumens can impart the following changes in properties:
* increased softening point
* improved low temperature flexibility
* greater elasticity
* improved aging characteristics.

Product Group: <b>SBS MODIFIED BITUMINOUS MEMBRANES</b>

Country of Origin: U.S.A.

;Year First Installed: 
:BC: 1998
:Canada: 1993
:Foreign: 1993

<u>DESCRIPTION</u>

Firestone developed prefabricated sheet membranes in 1987 and introduced SBS Modified Bitumen&#8217;s in 1991, producing an elastomeric blend with exceptional elongation recovery characteristics. Reinforcing mats consisting of polyester, fibreglass and a combination thereof, are saturated and coated with SBS elastomer modified bitumen to produce roof membranes designed for use in a variety of roof systems. Firestone manufacturers a variety of membranes, each of which is designed to meet the requirements of a variety of roof constructions. The &#8220;SBS&#8221; and &#8220;SBS FR&#8221; membrane series are designed to meet the structural, climatic and design needs of a range of applications. These membranes are available with a variety of surfacing materials including; ceramic granules, polypropylene film or sand. Depending on the back surfacing, the membranes may be installed in hot asphalt, in asphalt cold process adhesive, by heat welding or peel and stick self-adhesive. Ceramic granules for cap sheets are available in several colours. If high reflectivity is required, UltraWhite membranes are covered with granules having an initial solar reflectance of 0.72 and an initial thermal emittance ranging from 0.84 to 0.92. The solar reflectance index (SRI) of the UltraWhite membranes range from 87 to 89 as per ASTM E 1980-01.

;<u>PART 1 - GENERAL</u>
:The roofing assembly / material information published by the <b>RCABC <i>Roofing Practices Manual</i></b> does NOT represent a complete set of the manufacturer&#8217;s published data, nor does it represent a detailed specification. The preparation of a detailed specification is the responsibility of the design authority.

;1.1 <u>SYSTEM DESCRIPTION</u>
:.1 Two-ply roof membranes: The first ply consists of a base sheet, which may be applied in hot asphalt, asphalt cold process adhesive, fully heat welded, mechanically attached or self-adhered with a heat welded cap sheet. The second ply consists of a cap sheet applied in hot asphalt, cold process adhesive or by heat welding.

;1.2 <u>COMPOSITION</u>
:.1 SBS Compound: When a compatible bitumen is modified by the addition of SBS polymer, the combination provides the desirable properties necessary to ensure the long term performance of the completed roof system. Compatibility of the components, proper mixing and finished product preparation are ensured by production quality control and follow-up testing which ensures long term performance. These properties may be obtained only with a suitable SBS / bitumen compatibility and proper preparation.

:The compound in a roofing sheet provides:
:* Waterproofing
:* Elasticity
:* Aging performance
:* Flexibility

:.2 Reinforcement: The reinforcement of an SBS modified sheet provides enhancement to the compound. Polyester mat provides puncture resistance, toughness and dimensional stability upon which an SBS roof system depends for performance. A roof system relies upon the combination of compound flexibility and reinforcement toughness to resist hail and foot traffic damage. Polyester allows the SBS membrane to flex and recover while retaining its strength and toughness.
:.3 Aging: The aging properties of an SBS modified sheet are dependent on SBS / bitumen blend and the chemistry of the system. All roof systems experience heat exposure. Quality SBS modified bitumen blends age much more slowly than conventional blown asphalt.
:.4 Thickness: The aging properties of an SBS modified sheet are influenced by thickness. Thicker sheets age more slowly. Heat welded membranes should have a minimum back coating thickness of 1 mm asphaltic compound.

;1.3 <u>DELIVERY, STORAGE AND HANDLING</u>
:.1 All materials must be stored out of the weather in a clean, dry area in the original packages with the manufacturer&#8217;s labels intact.
:.2 All materials must be stored on end at a minimum of 4&#186;C (40&#186;F) and a maximum of 60&#186;C (140&#186;F).
:.3 If materials are stored temporarily, they must be stored on end, elevated from the roof surface or the ground, on a pallet and covered by a light colored opaque tarp.
:.4 Materials stored on the roof must be stored in a safe matter not to exceed the allowable live load of the storage area.
:.5 Care must be taken when transporting and handling Firestone SBS rolls to avoid physical damage.
:.6 Isolate Firestone modified bitumen sheets from contact with waste products, petroleum products, grease, oil and animal fats.

;1.4 <u>SITE CONDITIONS</u>
:.1 Slope: Roof slopes which exceed &#189;" in 12" (4.2%) require the following:
::.1 The building owner or the design professional intending to specify back-nailing should consider geographic location, specific job conditions, accepted area application practices and the type and grade of materials specified when creating an actual specification for a project.
::.2 When the slope of the roof exceeds &#189;" in 12" (4.2%) and hot asphalt attachment is specified, Firestone requires Firestone SBES Mopping Asphalt or CSA A123.4, Type III (3) asphalt be used.
::.3 Contact Firestone Roof Systems Solutions Group for additional requirements regarding roof slopes over 3" in 12" (25%).
::.4 For roof slopes up to and including &#189;" in 12" (4.2%), the side laps can be installed parallel or perpendicular to the slope.
::.5 For roof slopes greater than &#189;" in 12" (4.2%), the membrane must run parallel to the slope and be back-nailed.
::.6 For non-nailable decks and nailable decks with insulation, the cap sheet must be cut to conform to the spacing of nailers. Using capped nails, nail the end lap across the width of the sheet, with the first nail spaced &#190;" (19 mm) from the leading edge of the sheet. The remaining nails are to be spaced approximately 3" (76.2 mm) on centre. The nails should be staggered across the width of the nailer. Firestone fasteners and plates may be used in lieu of cap nails. Four per end lap are required. 
::.7 For nailable decks with no insulation, the cap sheet must be cut to conform to nailer spacing. Using capped nails or Firestone fasteners and plates, nail the end lap across the width of the sheet, with the first nail spaced &#190;" (19 mm) from the leading edge of the sheet. The remaining nails are to be spaced approximately 3" (76.2 mm) on centre. The nails should be staggered across the width of the nailer. Firestone fasteners and plates may be used in lieu of cap nails. Four per end lap are required.
::.8 Cap nails must have 1" (25.4 mm) diameter heads with steel head only. The shank must be minimum 11 gauge (2.3 mm) annular ring or spiral shank and be FM approved.

The board should have a minimum 1.5" (38.1 mm) bearing on the steel deck flange. Cantilevering insulation boards over deck flutes can fracture insulation boards, reducing the support for the membrane, making it susceptible to puncture.
::.6 If present, it is required that phenolic insulation be removed. Once removed, a visual inspection of the deck condition and other components is required. It is the building owner or his design professional&#8217;s responsibility to determine the condition of the deck. All deteriorated components must be replaced as necessary.

;<u>PART 3 - EXECUTION</u>

;3.1 <u>PREPARATION</u>
:.1 Apply roofing materials over clean, dry surfaces in accordance with good roofing practices of the RGC.
:.2 Ensure that moisture and contaminates are completely removed from the substrate prior to membrane application.
:.3 Prime all metal flashings to be installed in the membrane and allow primer to dry prior to installation.
:.4 Use only compatible primers and adhesive, mastics or sealants.
:.5 Provide adequate protection against fire, particularly when using propane torch-applied membranes.
:.6 Torch base sheets to approved substrates only.

;3.2 <u>INSULATION</u>
:.1 Mechanically fasten insulation over nailable decks, in accordance with RGC Guarantee Standards.

;3.3 <u>APPLICATION INSTRUCTIONS FOR A TWO-PLY SYSTEM</u>
:.1 Beginning at the low point of the roof, apply the membrane base sheet to the substrate using a minimum side lap of 3" (76 mm) and an end lap of 6" (150 mm). Stagger end joints. Terminate the base sheet at the top of the cant strip. Do not adhere base sheet to cant strip.
:.2 Beginning at the low point of the roof, fully adhere the cap sheet to the base sheet. Side laps must be a minimum of 3" (76 mm) and end laps must be a minimum of 6" (150 mm). Position base sheet laps so that the distance between base sheet laps and cap sheet laps shall not be less than 12" (300 mm).
:.3 Stagger end laps from course to course so that at no end lap will be closer than 12" (300 mm) from the preceding and succeeding end lap.
:.4 Provide a smooth application, free of air pockets, wrinkles, fishmouths or tears.

;3.4 <u>JOB SITE CONSIDERATIONS</u>
:.1 During the construction process, the roofing contractor is responsible for ensuring that all components of the Firestone roof system, including the finished areas are protected from damage, including, but not limited to:
::1.1 Damage that may result from the continued construction process.
::1.2 Discharges such as petroleum products, greases, oils (mineral and vegetable), animal fats and other by-products.
::1.3 Direct contact with continuous steam or heat sources when the in-service temperature is in excess of 60&#186;C (140&#186;F).
:.2 All safety regulations required by agencies having jurisdiction must be followed.
:.3 Refer to the Firestone Technical Information Sheet "Recommended Guidelines for Working on an Occupied Building" for specific guidelines when installing adhesives or asphalt products on an occupied building.
:.4 Cold weather conditions:
::4.1 When the outside temperature is below 4.4&#186;C (40&#186;F), installation of the Firestone roof system may required additional application precautions:
::* For a minimum of 24 hours before installation, adhesives and sealants should remain in an environment between 15.5&#186;C (60&#186;F) and 26.6&#186;C (80&#186;F).
::* Materials should be used within four hours of removal from a heated storage area. If materials area not used within that time period, they should be returned to the heated storage area until the temperature of the material returns to the temperature of the heated storage are. Typically, this is 24 hours.
::* Certain products may be damaged when allowed to freeze. Do not use any products that have been frozen without written permission from Firestone.
::* Refer to the product Firestone Technical Information Sheet (TIS) for application and temperature restrictions.
::4.2 For additional information and guidelines, see the Firestone Asphalt Roofing Application Guide and the CRCA Roofing and Waterproofing Manual.

;3.5 <u>ASPHALT PRODUCTS</u>
:.1 Assure that all health and safety measures are followed when installing hot asphalt to protect the installers as well as the occupants of the building. Assure compliance to all building codes and safety regulations when using hot asphalt.
:.2 Asphalt for installing the flashings and / or the roof membrane base sheet, base plies and cap sheets must be Firestone SBES Mopping Asphalt or either CSA A123.4, Type III (3) or Type II (2). Asphalt selection must be suitable for roof slope. All asphalt must be tested in accordance with ASTM D 312 and be certified by the supplier that it meets the minimum requirements for the specific type.
::2.1 Mopping asphalt must never be heated above the flashpoint temperature.
::2.2 Mopping asphalt must never be heated above the finished blowing temperature for more than 4 hours.
:.3 Asphalt Primer: Asphalt primer must meet the requirements of ASTM D 41.
:.4 When hot asphalt is required, Firestone requires that Firestone SBES Mopping Asphalt or CSA A123.4, Type III (3) asphalt be used.
:* In all SBS systems.
:* Where the slope exceeds &#189;" in 12" (4.2%).
:.5 Asphalt properties may change when stored at high temperatures for long periods of time. Asphalt may become harder or may experience what is known as &#8220;fallback&#8221;. Fallback is the degradation of the asphalt to the point that its physical properties (i.e. softening point) deteriorate which could then cause roof slippage. To reduce the chances of fallback, the following recommendations should be implemented:
::5.1 Use higher softening point asphalt.
::5.2 Decrease the kettle temperature as much as possible, while maintaining the minimum application temperature.
::5.3 Use material as quickly as possible, thus reducing exposure time.
::5.4 Insulate all lines and equipment used to transport asphalt.

:.1 Two-ply roof membranes: the first ply consists of a base sheet; applied with hot asphalt, cold adhesive fully heat welded, with adhesives and heat welded seams, self-adhered with self-stick products; the second ply consists of a cap sheet applied with hot asphalt, cold adhesive or heat welding.

;1.2 <u>PROJECT CONDITIONS</u>
:.1 Do not apply roofing insulation or membrane to damp deck surface.
:.2 Do not expose materials subject to water or solar damage in quantities greater than can be weatherproofed during same day.
:.3 All slopes greater than 2:12 (17%) require back-nailing to prevent slippage of the ply sheets. Use ring or spiral-shank one (1) inch (25 mm) cap nails, or screws and plates at a rate of one (1) fastener per ply (including the membrane) at each insulation stop. Place insulation stops as per RGC Guarantee Standards (Section 2.1.1) On non-insulated systems, nail each ply directly into the deck at the rate specified above. When slope exceeds 2:12 (17%), install all plies parallel to the slope (strapping) to facilitate backnailing. Install four (4) additional fasteners at the upper edge of the membrane when strapping the plies.
 
;1.3 <u>MANUFACTURER&#8217;S SERVICES</u>
:.1 Applicator training: Garland membranes are applied by GARLAND APPROVED RCABC <u> MEMBER APPLICATOR ONLY.</u>
:.2 Technical service: technical representatives are available for consultation and field training; owners, architects, and engineers are assisted in the selection and proper use of Garland materials by technical representatives. 
:.3 Specification / Drawings: complete specifications and detail drawings are available upon request.

;<b>Part 3 &#8211; EXECUTION</b>
 
;3.1 <u>PREPARATION</u>
:.1 Ensure membrane substrate is rigid, dry, smooth, compatible, free of fins and sharp edges, and clean of all
:.2 Ensure all openings, walls, and projections through the roof are firmly affixed and cant strips, reglets and nailing strips are in place.
:.3 A thermal barrier may be required between the roof deck and some insulations. Building code and insurance requirements to be identified by design authority.
 
;3.2 <u>PRIMER</u>
:.1 Prime wood, concrete, and metal surfaces to be directly adhered with bituminous membranes; allow to dry.
 
;3.3 <u>APPLICATION INSTRUCTION FOR A TWO SYSTEM </u>
:.1 <u>BASE SHEET INSTALATION (TWO PLY SYSTEM) HOT OR COLD</u>
::A) Base sheet: Install one (1) SBS base sheet in twenty five (25) lbs (11.3kg) per square of bitumen of cold adhesives shingled uniformly over the entire prepared substrate. Shingle in direction of slope of roof to shed water on each area of roof. Do not step on rolls until asphalt has cooled, fish mouths should be cut and patched.
::B) Lap ply sheet ends eight (8) inches (203mm).
::C) Lightly broom in base plies to assure complete adhesion.
::D) Extend plies two (2) inches (50mm) beyond top edges of cants at wall and roof projections and equipment bases.
::E) Install base flashing ply to all perimeter and projection details after membrane application.
:.2 <u>MODIFIED MEMBRANE INSTALATION HOT OR COLD</u>
::A) Solidly bond the modified membrane to the base layers with specified asphalt or cold adhesives at the rate of twenty five (25) to thirty (30) lbs. (11-13kg) per 100 square feet.
::B) The modified membrane roll must push a puddle of asphalt in front of it with asphalt or cold adhesives slightly visible at all side laps. Exercise care during application to eliminate air entrapment under the membrane.
::C) Apply pressure to all seams to ensure that the laps are solidly bonded to substrate.
::D) Install subsequent rolls of modified membrane across the roof as above with a minimum of four (4) inch (101mm) side laps and eight (8) inch (203mm) end laps. Stagger the end laps. Apply the modified membrane in the same direction as the previous layers but stagger the laps so they do not coincide with the laps of the base layers.
::E) Apply asphalt or cold adhesives no more than five (5) feet (1.5m) ahead of each roll being embedded.
:.4 <u>FLASHING MEMBRANE INSTALATION</u>
::A) Seal all curb, wall and parapet flashings with an application of mastic and mesh on a daily basis. Do not permit conditions to exist that will allow moisture to enter behind, around or under the roof or flashing membrane.
::B) Prepare all walls, penetrations, expansion joints [and where shown on the drawings] to be flashed with asphalt primer at the rate of one hundred (100) square feet per gallon (2.1square m per litre). Allow primer to dry tack free.
::C) Use the modified membrane as the flashing membrane. Adhere to the underlying base flashing ply with specified asphalt unless otherwise noted in these specifications. Nail off at a minimum of eight (8) inches (203mm) o.c. from the finished roof at all vertical surfaces.
::D) Solidly adhere the entire sheet of flashing membrane to the substrate.
::E) Seal all vertical laps of flashing membrane with a three-course application of trowel-grade mastic and fiberglass mesh.
::F) Coordinate counter flashing, cap flashings, expansion joints, and similar work with modified bitumen roofing work.
::G) Coordinate roof accessories, miscellaneous sheet metal accessory items, including piping vents and other devices with the roofing system work.
 
;3.4 <u>APPLICATION INSTRUCTION FOR A TWO PLY SYSTEM &#8211; HOT WELDED</u>
:.1 <u>BASE SHEET INSTALATION (TWO OR THREE PLY SYSTEM)</u>
::A) Install one layer of SBS Torch Base Sheet to a properly prepared substrate. Shingle in proper direction to shed water on each area of roofing.
::B) To a suitable substrate, lay out the roll in the course to be followed and unroll six (6) feet (1.8m).
::C) Using a roofing torch, heat the surface of the coiled portion until the burn-off backer melts away. At this point, the material is hot enough to lay into the substrate. Progressively unroll the sheet while heating and press down with your foot to insure a proper bond.
::D) After the major portion of the roll is bonded, re-roll the first six (6) feet (1.8m) and bond it in a similar fashion.
::E) Repeat this operation with subsequent rolls with side laps of four (4) inches (101mm) and end laps of eight inches.
::F) Give each lap a finishing touch by passing the torch along the joint and spreading the melted bitumen evenly with a rounded trowel to insure a smooth, tight seal.
::G) Extend underlayment two (2) inches (50mm) beyond top edges of cants at wall and projection bases.
::H) Install base flashing ply to all perimeter and projections details.
:.2 <u>MODIFIED MEMBRANE APPLICATION</u>
::A) Install HPR torch-on membrane as described below.
::B) Over the SBS Torch Base Sheet underlayment(s), lay out the roll in the course to be followed and unroll six (6) feet (1.8m). Seams for the top layer of modified membrane will be staggered over the SBS Torch Base Sheet seams.
::C) Using a roofing torch, heat the surface of the coiled portion until the burn-off backer melts away. At this point, the material is hot enough to lay into the substrate. Progressively unroll the sheet while heating and press down with your foot to insure a proper bond.
::D) After the major portion of the roll is bonded, re-roll the first six (6) feet (1.8m) and bond it in a similar fashion.
::E) Repeat this operation with subsequent rolls with side laps of four (4) inches (101mm) and end laps of eight (8) inches (203mm).
::F) Give each lap a finishing touch by passing the torch along the joint and spreading the melted bitumen evenly with a rounded trowel to insure a smooth, tight seal.
:.3 <u>FLASHING MEMBRANE INSTALATION</u>
::A) Seal all curb, wall and parapet flashings with an application of mastic and mesh on a daily basis. Do not permit conditions to exist that will allow moisture to enter behind, around or under the roof or flashing membrane.
::B) Prepare all walls, penetrations, expansion joints [, and where shown on the drawings] to be flashed with asphalt primer at the rate of one hundred (100) square feet per gallon (2.1 square m per litre). Allow primer to dry tack free.
::C) Use the modified membrane as the flashing membrane. Adhere to the underlying base flashing ply with specified asphalt unless otherwise noted in these specifications. Nail off at a minimum of eight (8) inches (203mm) o.c. from the finished roof at all vertical surfaces.
::D) Solidly adhere the entire sheet of flashing membrane to the substrate. Tops of all flashings that are not run up and over curb shall be secured through termination bar 6 inches (152mm) and sealed at top
::E) Seal all vertical laps of flashing membrane with a three-course application of trowel-grade mastic and fiberglass mesh.
::F) Coordinate counter flashing, cap flashings, expansion joints, and similar work with modified bitumen roofing work.
::G) Coordinate roof accessories, miscellaneous sheet metal accessory items, including piping vents and other devices with the roofing system work [as specified in other sections].

;3.5 <u>APPLICATION INSTRUCTION FOR SELF ADHERING SYSTEM</u>
:.1 <u>BASE PLY INSTALATION (TWO OR THREE PLY SYSTEM)</u>
::A) Fiberglass Plies: Install one (1) ply HPR SA Base Sheets shingled uniformly over the entire prepared substrate. Shingle in direction of slope of roof to shed water on each area of roof.
::B) Fiberglass Plies: Install two (2) plies HPR SA Base Sheets shingled uniformly to achieve two plies over the entire prepared substrate. Shingle in direction of slope of roof to shed water on each area of roof.
::C) Lap ply sheet ends eight (8) inches (203mm). Stagger end laps twelve (12) inches (305mm) minimum.
::D) Extend plies two (2) inches (51mm) beyond top edges of cants at wall and roof projections and equipment bases.
::E) Install base flashing ply to all perimeter and projection details.
:.2 <u>MODIFIED MEMBRANE INSTALATION</u>
::A) The modified membrane shall then by solidly adhered to the base layers.
::B) Starting at the low point, unroll the StressPly SA FR Mineral in the desired position. Fold the membrane back onto itself, remove the split back release film from the exposed side and gradually push the membrane into place. Apply even pressure along the entire length of the membrane from center to outer edges to avoid air pockets or wrinkles. Care should be taken to eliminate air entrapment under the membrane.
::C) Repeat for the other side. After the rolls are in place, apply uniform pressure to the entire roll area using a long handle weighted roller.
::D) Install subsequent rolls of modified membrane across the roof as above with a minimum of four (4) inch (102 mm) side laps and eight (8) inch (203 mm) end laps. Stagger the end laps. Apply the modified membrane in the same direction as the previous layers but stagger the laps so they do not coincide with the laps of the base layers.
::E) Where a lap is to be made to the granular surface, vigorously brush loose granules from the surface to be mated and carefully apply Flashing Bond to the granular surface. And allow 5-10 minutes to flash. Join the two surfaces and using a small metal roller or other suitable roller, firmly press into place. Roll edges firmly to ensure positive adhesion.
:.3 <u>FLASHING MEMBRANE APPLICATION</u>
::A) Seal all curb, wall and parapet flashings with an application of mastic and mesh on a daily basis. Do not permit conditions to exist that will allow moisture to enter behind, around or under the roof or flashing membrane.

<u>DESCRIPTION</u>

Hal Industries Inc. has been manufacturing asphalt roofing products for the flat roofing industry since 1974.

Asphalt available from B.C. refineries has been shown to have excellent compatibility with SBS polymers. Hal Industries Inc. uses a high-shear mixing process to blend raw asphalt with linear and branched SBS polymers. Limestone filler is then added as a thickener and conditioner and other minor ingredients are added as performance enhancers. This blend is used to saturate and coat non-woven polyester or fibreglass mat to produce a very flexible, high-quality membrane.

Cap sheets are surfaced with either mineral granules or aluminum foil on the top side and either sand or thermofusible polypropylene film on the underside. Base sheets are surfaced with sand or thermofusible polypropylene film, or a combination of these. Membranes may be installed either by the torch method or by embedment in hot asphalt.

Product designations are as follows:
# Therm-a-ply P180 series (Polyester-reinforced, moppable, torchable)
# Therm-a-ply G100 series (Fibreglass-reinforced, moppable, torchable)
# Alumatac P180 or Alumatac G100 (Aluminum foil-surfaced, moppable, torchable)
# Polymax 180 GS (Mineral-surfaced cap sheet, moppable)

;3.5 <u>BASE SHEET APPLICATION</u>
:.1 On slopes up to 1:12 (1" in 12"), install base sheet at right angles to slope, beginning at low point of roof.
:.2 On slopes exceeding 1:12 (1" in 12"), install base sheet parallel to slope, and nail upper edge at 200 mm (8") o/c with minimum 25 mm (1") headed roofing nails.
:.3 Unroll and align membrane, lap sides 75 mm (3") and ends 150 mm (6"). Always keep several rolls laid out on the roof deck ahead of the installation to permit relaxation and acclimatization to take place.
:.4 Install each aligned sheet by re-rolling approximately halfway and adhering each half alternately.
:.5 Asphalt-adhered sheet (sanded side down) (<b>Use Type 3 or Type 4 asphalt only</b>):
:* Apply hot asphalt to the roof deck surface at its equiviscous temperature [minimum 205&#176;C (400&#176;F)] at a rate of 1.2 kg / m&#178; (25 lb / 100 sq ft).Maintain a puddle just ahead of the advancing roll at all times, allowing a positive bleed-out to occur at each edge of the sheet.<b>Never mop more than one metre ahead of roll.</b>
:* Press the membrane into the hot asphalt.
:* Slit any fishmouths and press in while asphalt is still hot.Apply a patch to cover any slits by embedding the patch into hot asphalt.
:* Use a roofer's torch to melt polyfilm and prepare a selvedge under each end lap.
:.6 Torch-adhered sheet (polyfilm-surfaced side down):
:* Using a trigger-handled roofer's torch, heat the roll surface evenly until the polyfilm surfacing melts and a slight flow of coating occurs.Apply heat to selvedge edge of previous sheet while at the same time advancing the roll with a hooked bar.A slight bead of coating should squeeze out at the lap.

;3.6 <u>CAP SHEET APPLICATION</u>
:.1 Install cap sheet in the same direction as the base sheet, starting at low point and staggering all laps.Offset the side laps from base sheet side laps by a minimum of 300 mm (12") and end laps by a minimum of 1 m (39"). Overlap at sides must be no less than 75 mm (3"), and at ends no less than 150 mm (6").
:.2 Keep several rolls laid out on the roof deck ahead of the installation to permit relaxation and acclimatization to take place.
:.3 Install each aligned sheet by re-rolling approximately halfway and adhering each half alternately.
:.4 Asphalt-adhered sheet (to sanded base sheet only):
:* Apply hot asphalt to the base sheet surface at its equiviscous temperature [minimum 205&#176;C (400&#176;F)] at a rate of 1.2 kg / m&#178; (25 lb / 100 sq ft).Maintain a puddle just ahead of the advancing roll at all times, allowing a positive bleed-out to occur at each edge of the sheet.<b>Never mop more than one metre ahead of the roll.</b>
:* Roll out and press the membrane into the hot asphalt, eliminating any trapped air pockets.Avoid walking on newly-placed cap sheet until it cools.
:.5 Torch-adhered sheet:
:* Using a trigger-handled roofer's torch, evenly heat the underside of the cap sheet roll and the top side of the base sheet, creating a liquid sheen on both surfaces.Advance the roll with a hooked bar, ensuring that a minimum 8 mm (3/8") bead of melted coating exudes at the lap edge.Maintain a puddle of melted coating ahead of the roll.

;3.7 <u>MEMBRANE FLASHING</u>
:.1 Cut flashing membrane into suitably-sized pieces one metre wide.Allow for minimum 75 mm (3") side lap, 150 mm (6") lap onto roof deck, and 200 mm (8") up vertical surface.
:.2 Asphalt-adhered flashing: apply a full mopping of hot asphalt to the roof surface and press in each flashing sheet ensuring good adhesion.Use a hand trowel to aid in the process.
:.3 Torch-applied flashing: use a detailing torch to heat the underside of each flashing sheet and the roof surface.Press each sheet into position with the aid of a hand trowel.
:.4 Wherever practical, we recommend flashing be torch-applied rather than asphalt-adhered wherever practical.

;3.8 <u>PRECAUTIONS</u>
:.1 When a torch-applied sheet is to be lapped over a granulated surface (such as end laps), <u>always</u> embed granules on the lower sheet with a heated hand trowel prior to making the lap.
:.2 When a mop-applied sheet is to be lapped over a polyfilmed surface (such as end laps), <u>always</u> torch the film on the lower sheet prior to making the lap.
:.3 Never install membranes over a surface which contains moisture.Moisture trapped between plies will cause blistering in the future.
::If a base sheet has been installed and subsequently rained-on prior to cap sheet installation, moisture may become trapped under the polyfilm surfacing.As a precaution against entrapping this moisture during cap sheet installation, torch all polyfilm surfaces at least one hour prior to installing the cap sheets.

<u>DESCRIPTION</u>

The main components of the roofing and waterproofing systems are bitumen modified with SBS (Styrene Butadiene Styrene) and either fibreglass or polyester reinforcement.

The system normally consists of two plies of membrane. The membrane is produced in 1 m (39") wide rolls and varies in thickness from 2 mm (0.08") to 5 mm (0.2") depending on use and reinforcement.

The membrane is constructed by coating either a fibreglass or polyester fabric, on both the top and bottom, with high performance modified bitumen. The lower surface is either sanded or receives a poly surface while the top surface is covered with granules or sand.

The system is constructed in the field by either mopping with hot asphalt, torch welding, self-adhering, mechanically fastening or cold applied adhesive. In protected membrane roofing, granule-surfaced cap sheets are normally required on flashings only, with sanded surface cap sheets on field of roof.

<i>Product Group:</i> <b>SBS MODIFIED BITUMINOUS MEMBRANES</b>

<i>Country of Origin:</i> Canada

<i>Country of Manufacture:</i> Canada, USA, Belgium, France

;Year First Installed:
:B.C.: 1985
:Canada: 1985

<u>DESCRIPTION</u>

The main components of the roofing and waterproofing systems are the TORCHFLEX and MODIFLEX membranes: tough, flexible, SBS polymer modified bitumen prefabricated sheets, appropriately reinforced and surface-finished for specific applications.

The highest quality raw materials are utilized in a manufacturing process which saturates and coats non-woven glass or polyester fabric with SBS polymer modified bitumen.

The membranes are installed on the job site by hot asphalt or propane torch welding, bonding the adjacent sheets and flashing plies to form an integral roofing / waterproofing system.

PART 1 - GENERAL

#:The roofing assembly / material information published in the <b>RGC<i> Roofing Practices Manual</i></b> does NOT represent a complete set of the manufacturer's published data, nor does it represent a detailed specification. The preparation of a detailed specification is the responsibility of the design authority.

## <u>RANGE OF APPLICATION</u>
### For use over roof decks in commercial, institutional, and industrial applications, wherever built-up roofing is presently used.

## <u>ANCILLARY PRODUCTS</u>
### Asphalt: roofing asphalt conforming to CSA A123.4-M Type 3.
### Nails: 12 gauge Simplex nails (minimum size: 1-1/2").
#PART 3 - EXECUTION
## <u>LIMITATIONS / CAUTIONS</u>
### Apply roofing materials over clean, dry surfaces in accordance with RGC good roofing practices.
### Use only compatible primers and adhesives, mastics, or sealants.
### Provide adequate protection against fire, particularly when using propane torch-applied membranes.
### Torch base sheets to suitable substrates only; many rigid insulations require suitable overlay. Wood fibreboard and fibrecants are not acceptable.
## <u>PREPARATION</u>
### Surfaces to receive membranes must be clean, dry, and primed with compatible primer as required.
## <u>INSULATION</u>
### Mechanically fasten insulation over nailable decks, in accordance with <i>RGC Guarantee Standards.</i>
### Embed insulation in a 1.5 kg / m&#178; (30 lb / square) mopping of hot asphalt over non-nailable deck.
### Install 11 mm (7/16") asphalt-impregnated fiberboard as an insulation overlay <b>where required</b> by <i>RGC Guarantee Standards.</i>
### Install wood nailing strips on slopes exceeding 1:12 (1" in 12").
### Protectoboard is an accepted insulation overlay. In applications requiring two layers of overlay (i.e. over heat sensitive insulations), protected board is accepted as the second layer.
###Fasten Protectoboard overlay using nine fasteners per board, as shown, or alternately adhere Protectoboard with hot asphalt, according to <i>RGC Guarantee Standards</i>.
###:[[File:5.1.2.1.jpg]]
## <u>ROOF MEMBRANE APPLICATION</u>
### Asphalt-adhered: apply asphalt to substrate at a rate of 1.2 to 1.5 kg / m&#178; (25 to 30 lb / square), at minimum 205&#176;C (400&#176;F) and maximum 260&#176;C (500&#176;F) at point of application; mop no further than 1 m (3') ahead of unrolling material; lap sides 75 mm (3") and ends 150 mm (6") unless specified otherwise.
### Torch-adhered: torch on to suitable substrates or base sheets; lap sides 75 mm (3") and ends 150 mm (6").
### Adhesive-applied: install IKO's adhesives and membranes according to IKO's printed instructions.
### Use of cant strips is recommended. Where used, install base to the cant. Where not used, install base ply to the base of vertical surfaces.
### Start at low point and, where slopes are 1:15 (3/4" in 12") or less, start at right angles to the slope; on slopes greater than 1:15 (3/4" in 12") install parallel to the slope.
### Stagger end laps minimum 300 mm (12").
### Install base sheet stripping, starting at the outer edge of parapet, across top face, down inside vertical surface, over base sheet on cant strip (if present), and out a minimum of 150 mm (6") onto &#8220;flat&#8221; portion of roof, fully bonded throughout (unless specified otherwise); apply base sheet stripping over primed flanges of installed metal accessories.
### Install membrane cap sheet parallel to base sheet, with laps of cap sheet being offset a minimum of 300 mm (12") from those of base sheet, using same side and end laps as base sheet; embed granules (do not remove) prior to bonding onto granular surfaces.
### Limit asphalt / bitumen &#8220;bleed-out&#8221; at laps on granular surfaces to a maximum of 10 mm (3/8") width.
### Extend cap sheet stripping a minimum of 150 mm (6") onto &#8220;flat&#8221; portion of roof.
### Check laps with round-nosed roofing trowel as work proceeds; reseal unbonded areas and voids; repair punctures or tears with patches of similar materials torch-welded to surface.
### Consult IKO Industries Ltd. Technical Department for recommendations on fastener type, rates and pattern for mechanically attached membranes.

<i>Manufacturer:</i> <b><h2>MALARKEY ROOFING COMPANY</h2></b>

<i>Contact Address:</i> See Membership List Section 1
 
<i>Product Group:</i> <b>SBS MODIFIED BITUMINOUS MEMBRANES</b>

<i>Country of Origin:</i> United States 

<i>Country of Manufacture:</i> U.S.A.

;Year First Installed:
:U.S.: 1978
:Canada: 1979
 
<u>DESCRIPTION</u>

Malarkey Roofing has been manufacturing bituminous roofing products since 1956 and introduced SBS Modified Bituminous membranes in 1978. Only the highest quality raw materials are utilized in a manufacturing process which impregnates and coats fibreglass or Polyglass reinforced mats with SBS modified bitumen.

Malarkey manufactures a wide variety of membranes designed to satisfy the demands of varied roof and climatic conditions. These membranes are available with ceramic granules, metal foil or sanded finishes designed to be installed with hot asphalt, propane torch or cold-process adhesives in all types of roofing / waterproofing systems.

;PART I - GENERAL

:The roofing assembly / material information published in the <b>RGC <i>Roofing Practices Manual</i> </b>does NOT represent a complete set of the manufacturer's published data, nor does it represent a detailed specification. The preparation of a detailed specification is the responsibility of the design authority.

;1.1 <u>RANGE OF APPLICATION</u>
:.1 For use over roof decks in commercial, institutional and industrial applications, wherever built-up roofing is presently used.
:.2 As a fully adhered 2-ply (or more) system on flat, curved or domed roofs over most types of insulation.
:.3 As a roofing membrane over existing roofs in recover or replacement applications.

;1.2 <u>DELIVERY. STORAGE AND HANDLING</u>
:.1 Deliver and store materials in original containers showing product and manufacturer's name and date of manufacturer.
:.2 Store rolls on end only, selvage edge up, elevated from contact with ground and moisture. Cover with plastic tarpaulin or place in weatherproof shelters so as to keep materials dry at all times.
:.3 Distribute materials on roof to avoid concentrated loading, having first discarded rolls which may have been flattened, creased or otherwise damaged.

;1.3 <u>SITE CONDITIONS</u>
:.1 Slope range: from dead level up to and including vertical. The choice of membrane combination and its suitability for a particular slope is governed by the type of deck, insulation used, fastening capability, application method, type of finished surface of membrane and potential for stress on the membrane. Please consult Malarkey for assistance in identifying these factors and in determining the correct choice of materials.
:.2 <b>Slope Limitations</b>:
::Minimum recommended slope 1:50 (1/4" in 12")
::Mechanically fastened over 1:8 (1-1/2" in 12")
:.3 Minimum ambient application temperatures:
::Hot asphalt applied -7&#176;C (+20&#176;F)
::Torch applied determined by tolerance of applicator
::Cold process applied +4&#176;C (+40&#176;F)
:.4 Chemical incompatibility: incompatible with coat tar pitch. Not resistant to oil or most petroleum products. Consult Malarkey for specific requirements.

;1.4 <u>STANDARDS AND APPROVALS</u> (for specific membranes or assemblies consult manufacturer)
:.1 CAN / ULC Class A or B.
:.2 Underwriters Laboratories Class A or B
:.3 Factory Mutual meets or exceeds 190 test for wind uplift.
:.4 Canadian General Standards Board conforms to CGSB 37-GP-56M.
:.5 Warnock Hersey Listed

;1.5 <u>MANUFACTURER'S SERVICES</u>
:.1 Applicator training: warranted Malarkey Roofing Systems are applied by approved roofing contractors.
:.2 Technical Services: a Local Malarkey representative is available for consultation and field training.
:.3 Specifications / drawings available from specifications manual.
:.4 Seminars presented upon request.
;1.6 <u>EQUIPMENT</u>
:.1 Torches: use only torches designed for torching roofing material.

;PART 3 - EXECUTION

;3.1 <u>LIMITATIONS / CAUTIONS</u>
:.1 Apply roofing materials over clean, dry surfaces in accordance with RGC good roofing practices.
:.2 Ensure roof has adequate slope to drain.
:.3 Use only compatible adhesives / mastics / sealants.
:.4 Provide adequate protection against fire, particularly when using propane torches.
:.5 Apply base sheets with hot asphalt or cold process adhesive only to adequately prepared primed substrate.
:.6 Ensure moisture, in any form, is completely removed from substrate prior to membrane application.

;3.2 <u>PRIMER</u>
:.1 Prime concrete, masonry, wood and metal surfaces to be directly bonded with bituminous membranes.

;3.3 <u>INSULATION</u>
:.1 Mechanically fasten insulation over nailable decks, in accordance with <i>RGC Guarantee Standards.</i>
:.2 Embed insulation in a 1.5 kg / m&#178; (30 lb / square) mopping of hot asphalt over non-nailable deck.
:.3 Install 11 mm (7/16") asphalt impregnated fibreboard as an insulation overlay where required by <i>RGC Guarantee Standards</i>.
:.4 Install wood nailing strips on slopes exceeding 1:8 (1-1/2" in 12").
 
;3.4 <u>MALARKEY BASE SHEET</u>
:.1 Start at low point and apply at right-angles to slope. Where slope exceed 1:6 (2" in 12") install parallel to slope.
:.2 Asphalt-adhered: apply asphalt to substrate at a rate of 1.2 kg / m&#178; (25 lb / square), at minimum 205&#176;C. (400&#176;F) for Type I asphalt up to 230&#176;C (450&#176;F) for Type 4 and SEBS asphalt, at point of application. Mop no further than 1.5 m (5') ahead of unrolling roll of material. Lap sides 50 mm (2") and ends 150 mm (6") unless otherwise specified.
:.3 Cold-process adhered: apply to substrate at a rate of 0.8 L / m&#178; (2 gal / sq.), at a minimum ambient temperature of 4&#176;C (40&#176;F). Lap sides 50 mm (2") and ends 150 mm (6"), unless otherwise specified.
:.4 Backnail base sheet at 225 mm (9") o/c on slopes exceeding 1:8 (1-1/2" in 12"), into nailing strips if required.
:.5 Carry base sheet to 50 mm (2") above top of cant unless otherwise specified.

;3.5 <u>MALARKEY CAP SHEET</u>
:.1 Starting at low point, in same direction as base sheet, unroll and align cap sheet. Cut into maximum 5.03m (16.5') lengths. Stagger end laps a minimum of 900 mm (3'). End laps and side laps to be a minimum of 450 mm (18") from laps in base sheet.
:.2 Asphalt adhered: embed cap sheet in a full mopping of 1.2 kg / m&#178; (25 lb / square) asphalt at minimum 205&#176;C (400&#176;F) for Type I asphalt up to 230&#176;C (450&#176;F) for Type 4 and SEBS asphalt at point of application. Mop no further than 1.5 m (5') ahead of unrolling material. Broom sheets to ensure smooth wrinkle-free application. Ensure bleed-out of asphalt at all seams to obtain 100% adhesion. Embed Loose granules in bleed-out.
:.3 Cold-process applied: embed cap sheet in cold-process adhesive at a rate of 0.8 L / m&#178; (2 gal / square). Broom sheets to ensure smooth wrinkle-free application. Ensure bleed-out of cement at all seams to ensure 100% adhesion. Embed loose granules in bleed-out.
:.4 Torch adhered: torch onto suitable base sheet only. Ensure membrane is fully bonded as cap sheet is unrolled.
:.5 Back-nail cap sheet at 225 mm (9") o/c on slopes exceeding 1:8 (1-1/2" in 12").
:.6 Carry cap sheet 100 mm (4") above top of cant, and at least 150 mm (6") above finished roof system unless otherwise specified.

;3.6 <u>MALARKEY BASE AND CAP FLASHINGS</u>
:.1 Install Malarkey base and cap flashings to extend a minimum of 150 mm (6") onto roof from base of cant and at least 200 mm (8") above finished roof system, unless otherwise specified.

<u>DESCRIPTION</u>
The main components of the roofing and waterproofing systems are the &#8220;Traditional&#8221;, &#8220;Sopralene&#8221; and &#8220;Elastophene&#8221; membranes, and the High Performance Composite systems, all tough, flexible SBS polymer modified bitumen prefabricated sheets, appropriately reinforced and surface finished for specific application.

The highest quality raw materials are utilized in a manufacturing process which saturates and coats non-woven glass, composite, or polyester fabric with SBS polymer modified bitumen.

The membranes are installed on the job site by hot asphalt, propane torch welding and cold and self adhesive techniques, bonding adjacent sheets and flashing plies to form an integral roofing/waterproofing system.

## <u>ANCILLARY PRODUCTS</u>

### Asphalt: roofing asphalt conforming to CSA A123.4M Type 3
### SEBS Modified Asphalt: roofing asphalt conforming to ASTM D6125

#<b><u>PART 3 - EXECUTION</u></b>

## <u>LIMITATIONS / CAUTIONS</u>

### Apply roofing materials over clean, dry surfaces in accordance with RGC good roofing practices.
### Use only compatible primers and adhesives / mastics / sealants.
### Do not torch direct to flammable substrates.
### Provide adequate protection against fire, particularly when using propane torch applied membranes.
### Torch base sheets to suitable substrates only; many rigid insulations require a suitable overlay; wood fibreboard and fibrecants are not acceptable.
## <u>PREPARATION</u>
### Surfaces to receive membranes must be clean, dry, and primed with compatible primer as required.
## <u>INSULATION</u>
### Mechanically fasten insulation over nailable decks, in accordance with <i>RGC Guarantee Standards.</i>
### Embed insulation in a 1.5 kg / m&#178; (30 lb / square) mopping of hot asphalt over non-nailable deck or adhere with Coltack or Duotack adhesive, or other approved adhesives.
### Install 11 mm (7/16") asphalt-impregnated fibreboard, 4.5mm Sopraboard, 12mm Xpress Board, Xpress EPS, Xpress ISO, or 12mm SoprabaseFR as an insulation overlay <b>where required</b> by <i>RGC Guarantee Standards.</i>
### Install wood nailing strips on slopes exceeding 1:12 (1" in 12"), or as required.
## <u>ROOF MEMBRANE APPLICATION</u>
### Asphalt-adhered: apply asphalt to substrate at a rate of 1.2 to 1.5 kg / m&#178; (25 to 30 lb / square), at minimum 205&#176;C (400&#176;F) and maximum 230&#176;C (450&#176;F) at point of application; mop no further than 1 m (3' ) ahead of unrolling roll of material; lap sides 75 mm (3") and ends 150 mm (6") unless specified otherwise. Soprasphalte M is recommended for all <b>interply </b>mopping of membranes. Contact manufacturer for application recommendations using SEBS Modified Soprasphalte M.
### Torch-adhered: torch onto suitable substrates or base sheets, fully bond membrane; lap sides 75 mm (3") and ends 150 mm (6") or as required by the applicable system assembly.
### Adhesive-applied: install Colply Adhesive Brush / Trowel and membranes according to Soprema's printed instructions.
### Self-adhered: Membranes used in base/cap field or stripping plies in 2 ply assemblies require substrate priming with Elastocol Stick, Elastocol 350, or Elastocol Stick H2O in almost all applications. Contact manufacturer for possible exceptions.
### Use of cant strips is optional; where used, install base sheet to bottom or top of cant; where not used, install base sheet to the base of vertical surfaces. Fiberboard Cant is not acceptable except in hot mopped asphalt applications.
### Start at low point and where slopes are 1:15 (3/4" in 12") or less at right angles to the slope; on slopes greater than 1:15 (3/4" in 12") install parallel to the slope.
### Stagger end laps minimum 300 mm (12") except in systems when soldiering and seam overlays are recommended.
### Consult Soprema Inc. for membrane flashing details; where gravel stop details are utilized, mastic under the gravel stop flange is required.
### Install base sheet stripping, starting at the outer edge of parapet, across top face, down inside vertical surface, over base sheet on cant strip (if present), and out minimum of 100 mm (4") onto field portion of roof. Apply base sheet stripping over primed flanges of installed metal accessories.
### Install membrane cap sheet parallel to base sheet, with laps of cap sheet being offset minimum of 300 mm (12") from those of base sheet, using same side and end lap widths as base sheet; embed granules (do not remove) prior to bonding onto granular surfaces.
### Limit asphalt / bitumen "bleed-out" at laps on granular surfaces to a maximum of 6 mm (1/4") width; conceal excess "bleed-out" and repair damaged granular finishes with matching loose granules from manufacturer.
### Extend cap sheet stripping minimum of 150 mm (6") onto field portion of roof, extend to top inside corner of parapets, or terminate 25 mm (1") higher than base stripping on walls.
### Check laps with round-nosed roofing trowel as work proceeds; reseal unbonded areas and voids; repair punctures or tears with patches of similar materials torch-welded to surface.
### Consult Soprema Inc. for recommendations on fastener type and pattern for mechanically fastened membranes.
### Consult Soprema Inc. for specific application and use for adhesive applied systems.

=5. SBS Application and Safety: Best Practices=

Modified bitumen roofing membranes represent the latest in the evolution of bituminous roofing systems.  However, some systems require that applicators use a propane-fuelled open flame torch to adhere the membrane.  When working with an open flame on the construction site, applicators must use extreme caution to prevent accidents.  Carelessness could lead to loss of property or life.

This section contains precautions for applying modified bitumen roofing.  The applicator will find proper procedures for working with equipment on the jobsite, and dealing with personnel.<b>NOTE:  If a fire occurs for any reason, call the fire department immediately, even if you put out the flames.  Some material may smoulder for hours before bursting into flames, and could be smouldering in places where the layman may not think to look.   Let the fire fighters do their job.  Safety is no accident.</b>

=== 5.1 EQUIPMENT ===
Applicators use an open flame to soften the bitumen on the underside of the membrane to make it adhere to the roofing substrate.  At a temperature of 1100<sup>o</sup>C (2000<sup>o</sup>F), the flame produced by liquid propane gas does an excellent melting job.  But used incorrectly or carelessly, the flame could damage the roof or the building and seriously injure the applicator.

Applicators should receive training in proper application, maintenance and safety procedures when handling torching equipment.

Operators should handle their equipment carefully.  Protect the soft brass valve of the gas cylinder.  It is easy to crack or break it.  A broken valve could turn the cylinder into a projectile. Check all cylinders before refilling.  Never overfill a cylinder. It could explode.

All applicators of modified bitumen should participate in the safety and training program.

==== 5.1.1 General ====
* Use well-built durable products that feature safety devices and are listed by Underwriters Laboratories of Canada (ULC).
* Follow the manufacturer's safety and operating instructions provided with the torch system.
* Check all equipment for wear. Remove and replace as necessary.
* Use soap solution to test for gas leaks before lighting, then check for proper operation of the torch.
* Check all fittings and other equipment on the applications equipment for leakage.
* Be sure that torching equipment is in good working order and that the cylinder valves are clean.
* Stop work and shut off flame if propane odour is detected.
* Stop work, investigate and make corrections if a leak occurs.* Keep non-applicators at least 3 m (10') from the flame.
* Protect your equipment: store it in a toolbox.
* Do not use matches or a cigarette lighter to test for gas leaks.
* Containers which hold or may have held flammable material must be kept clear of the torch or other heat sources.
* Do not use equipment that has been damaged or that is in need of repair.

==== 5.1.2 Tanks ====
* Protect cylinder valves; where possible use cylinders that have valve protection welded to the cylinder.
* Propane tanks are pressurized &#8211; do not puncture or subject to extreme heat.
* Secure propane tanks in an upright position and place them at least 3 m (10') from the open flame.
* Increase the size of the tank to keep frosting from occurring.
* Close the propane tank valve first and let the remaining gas burn out of the hose before closing the torch valve when shutting off the torch.
* Plug the valve with a plastic plug when cylinder is not in use.
* Do not turn a vapour draw tank on its side to increase pressure - liquid could escape.
* Do not heat a tank to increase pressure.
* Do not fill a propane tank that is in need of repair.
* Do not over tighten the brass fittings.

==== 5.1.3 Regulators ====
* Use an adjustable ULC listed regulator with the torch.
* Make sure flow of gas through the regulator is in the proper direction. Directional flow is stamped on regulator.
* Keep vent in pressure regulator clear at all times.
* Do not use an adjustable regulator with a higher pressure range than the one that came with the torch.
* Do not operate any pressure gauge beyond the top of its scale or near excessive heat (above 65&#176;C) or where there is excessive vibration.* Do not use equipment without a properly operating regulator.

==== 5.1.4  Hoses ====
* Check hoses for wear and tear.
* Use only hoses listed for propane gas by the Canadian Gas Association as applicable for the device.
* Use no more than 15 m (50') of hose at one time.

==== 5.1.5 Torches ====
* Use an adjustable pilot light with a complete shut-off.
* Only use a torch stand to direct flame upward when not in use. Do not use a trowel as a torch stand.
* Use only torch machines equipped with the same safety features as described for torches. They should also have individually adjustable torches. Use only torch trolleys and multiple head machines with approved safety valves.
* Ignite burner with a flint or electronic lighter. Matches or disposable lighters are unsafe substitutes.
* Do not play with a torch.  Treat the torch as if it is always burning.  A flame can be hard to see on a bright day and can burn skin or clothing instantly.  When working around mechanical equipment, it can be difficult to hear the torch operating.
*  Be very careful when working with torches in areas where you can not see.  Pull material away, heat it, and then apply it to the surface.
*  Do not leave lighted torch unattended.
*  Do not lay operating torch over the edge of a roof.
*  Do not lay an operating torch to rest on a propane tank.  If there is a gas leak, a fire could be ignited.

==== 5.1.6 Extinguishers ====
* Have at least one Class ABC fire extinguisher within 6 m (20' ) of each worker using a torch.
* Train each torch operator in the proper use of fire extinguishers.
* Direct the stream from a dry chemical-type fire extinguisher at the base of the fire from a distance of at least 3 m (10'). Sweep the fire away from you, starting at its nearest point and moving the chemical stream toward the farthest point.
* Do not try to put out a propane tank fire if it cannot be done without shutting off the cylinder valve OR tipping the cylinder. Let it burn and call the fire department.
* Do not place fire extinguisher too close to liquid propane gas equipment.  If fire results, you may not be able to get at fire extinguisher to put out the fire.

IF STILL IN DOUBT  &#8211;  DON'T USE IT.</b></center>

=== 5.2 BUILDINGS ===
Each building is different from every other building, and each roof design presents a new set of challenges to the roofing contractor.  The applicator of modified bitumen systems must adapt his standard safety procedures to meet the special requirements of the current job.  However, roofers should follow the basic rules presented in these pages.

The supervisor must conduct a fire risk assessment before any Torch Applied hot-work is started and complete their company's Hot-Works assessment form work.

The job supervisor should take extra care when working on a torch applied modified bitumen roofing project.  A responsible person should conduct a fire watch over the work area a minimum of one hour after all torches have been extinguished and record the findings of the fire watch on their company's fire watch form.  The delay will help guard against a smouldering fire going undetected at the end of the work day.  Check for potential "hot spots" with an infra-red scanner, especially at upstands, eg wall transitions, around penetrations such as vent pipes, intake vents and skylights etc.   <i>If accessible (new construction projects) check and scan the underside of the deck before ending your fire watch, or walk back through the building interior before concluding the fire watch.</i>

Applicators must take special care when torching at flashings, corners, or voids in the roof deck.  Never torch directly at these locations.  Always use self adhered or cold applied materials at these fire sensitive locations.

==== 5.2.1 General ====
* Use protective shielding when using torch application near any upstands.
* Shut down air conditioning units, exhaust fans and air intake fans in the work area at the roof control.  This must be coordinated with the owner or building maintenance staff.
* Do not work in an enclosed area where gas can accumulate.

==== 5.2.2 Substrates ====
* Use perlite, fibreglass, or concrete cant strips if cant strips are required.
* Use a protective base sheet on all wood decks and over ignitable insulation, can strips or other flammable surfaces.
* Look for any void, hole or gap in the substrate and repair.
* Use a base ply over all ignitable insulation surfaces, edges and over all joints between rigid insulation boards.  The base ply provides a protective covering for underlying ignitable materials.
* Install a cover board or base ply, acceptable to the membrane manufacturer, to separate polyurethane or polyisocyanurate roof insulations from the modified sheet and the torch.
* Install a cover board or base ply over all ignitable surfaces. Be sure base ply fits tightly around all roof deck openings and turns up the wall, so the flame cannot flash down and start a fire underneath the deck.
* Do not torch to wood fibre insulation, cant strip, wood or any ignitable material.

==== 5.2.3 Torching Methods ====
* Follow manufacturer's recommendations on torching to insulation and recover board surface.
* Use a small torch when flashing near details.
* Shield air conditioning units and other protrusions with when using the torch around them.
* Heat the membrane away from air conditioning units, fans, soil pipes and all other protrusions. Care must be taken to avoid flame being pulled into the building interior.
* Feather seams around details with a hot trowel, not open flame.
* Use self adhered or cold adhesive membrane flashings at corners, or voids in the roof deck.  Never torch directly.
* Use caution when torching near pipes in the event there is suction present.
* Do not torch anything you cannot see such as under air conditioning units or behind counter flashing.
* Do not torch near gas lines or near electric wires (such as around roof top equipment, etc.).
* Do not torch around flammable vents or plastic projections.
* Do not point the torch under rooftop equipment.
* Do not point the torch down open roof penetrations.
* Do not point the torch into corners or roof edges where dried wood or fibre may ignite (such as wood blocking or cant strip).
* Do not point the torch at low flashings where there is an overhang and flame could get up under the counter flashing, such as around skylights or prefabricated curbs with fibreboard sidewall insulation.
* Do not apply modified bitumen products directly over exposed conduits or pipes lying on the roof deck.
* Avoid prolonged contact with heat sensitive metals such as lead, as overheating of these metals could ignite underlying flammable services.
* Do not lay an operating torch directly onto the membranes &#8211; there is a danger both of fire and of damaging the membrane.
* Do not lay an operating torch on an open penetration on the roof.  If the penetration is part of an air intake system, the flames could be sucked into the building.

===5.3 PERSONNEL ===
Many construction-industry tradesman use open flames or flame tools in their jobs.  Heating and air conditioning contractors, welders and plumbers all use open flame at the job site.  These professionals are responsible for the safe use of their tools, just as the roofing contractor is responsible for the safe application of modified bitumen roofing systems.

Contractors must not only train their own men in using open flame application, but must also make sure the general contractor and his superintendents are familiar with the necessary safety precautions for using torch application of roofing membrane.

Some of the safety precautions will be considered unpleasant, such as wearing long-sleeve shirts and long pants in the summer, but the results &#8211; a safe, injury-free job site &#8211; are worth the effort.

==== 5.3.1 General ====
* Wear proper clothing: non-synthetic fabrics, long-sleeve shirt, long pants, boots, gloves and proper eye protection.
* Keep non-applicators at least 3 m (10' ) from open flame.
* Train, instruct, and warn employees on the use of torching equipment.
* Use extra caution around edges of insulation board. Cover exposed edges with a fire guard base ply to prevent flame from coming in contact with any ignitable material. Contact for any length of time with lead or other materials affected by heat should be avoided.
* Do not take anything for granted.  Be on guard against lapses in on-the-job safety.

=== 5.4 FIRE DEPARTMENT ===
For years fire departments have been learning the proper safety precautions necessary to prevent fires. Their expertise and assistance should be utilized whenever possible to supplement a company's safety training program.  By making the local fire department a part of your team, you are giving notice that in all cases Safety Comes First.

==== 5.4.1   Fire Department Recommendations ====
* Strict compliance with local fire codes must be maintained.
* Give written notice to the local fire department where required, and obtain any necessary permits.
* One fire extinguisher for each torch operator shall be on the roof at all times.

Report ALL fires to the fire department  &#8211;  even those that are extinguished quickly  &#8211; there may still be fire and / or smouldering in areas where a layman may not think to look.
