Contents

(PLASTOMERIC)

Thermoplastic materials are defined as polymers which soften when heated and harden when cooled. This process is repetitive provided the material is not heated above the point at which decomposition occurs. No cross-linking or vulcanization occurs. In addition to heat welding, some materials can be solvent welded. These welds develop bonding strengths equalling or surpassing the strength of the base materials.

Thermoplastics materials used for roof membranes include:

  • PVC (Polyvinyl Chloride)
  • EIP (Ethylene Interpolymers)
  • ECB (Ethylene Copolymer Bitumen)
  • TPO (Thermoplastic Polyolefins)
  • EPR (Ethylene Propylene Rubber)


6.2.1 PVC (Polyvinyl Chloride)

PVC is a thermoplastic material produced through the polymerization of vinyl chloride, resulting in a relatively hard, resinous material. This material is then formulated with compounds, such as plasticizers and stabilizers, depending on the physical properties required for end use. PVC formulations have been developed to suit numerous commercial and industrial applications.

PVC roof systems are single-ply membranes available either non-reinforced or reinforced with polyester fabric or glass fibres, and in thicknesses usually ranging from 1.2 mm to 2.0 mm, depending on the manufacturer. Non-reinforced PVC membranes may typically exhibit excessive shrinkage characteristics, thus their use is often discouraged. The membrane may be applied loose-laid and ballasted, mechanically fastened, or fully adhered. Seams are heat or chemically welded (see manufacturer’s requirements).

PVC membrane should conform to CGSB 37-GP-54M 1979, “Roofing and Waterproofing Membrane, Sheet Applied, Flexible, Polyvinyl Chloride” which lists two types of membrane, according to manufacture:

  • Type 1
non-reinforced
  • Type 2
reinforced

and four classes, according to end use:

  • Class A
non-exposed roofing
  • Class B
exposed roofing
  • Class C
waterproofing
  • Class D
flashing membrane asphalt compatible

This standard covers requirements such as “thickness, lap joint strength, permeability, tensile strength, elongation at break, low temperature flexibility, water absorption, resistance to accelerated weathering, dimensional change after stress relaxation, and cone penetration”

PVC membranes should be applied in conformance with CGSB 37-GP-55M 1979, “Application of Sheet Applied Flexible Polyvinyl Chloride Roof Membrane” and the membrane manufacturer’s printed instructions.

DESCRIPTION

The main component of the roofing and waterproofing systems is the Sarnafil Membrane, a tough flexible polyvinyl chloride (PVC) sheet, appropriately reinforced and modified for specific applications. The highest quality raw materials are utilized in a manufacturing process which saturates and fuses a non-woven glass fibre or polyester fibre fabric reinforcement with a PVC Plastisol into a single homogeneous sheet. The sheets are joined on the job site by a hot air welding / fusion process to adjacent sheets or flashings to form an integral roofing system. Larger than standard or different shapes may be prefabricated to suit job requirements.

6.2.2 TPO (Thermoplastic Polyolefin)

TPO single-ply membranes are made of flexible polyolefin polymers. TPO polymers are formed by chemically linking up olefin molecules that soften when heated. This characteristic permits TPO membranes to be heat-welded for seaming of sheets and membrane flashings.

The polymers used to form TPO membranes vary between manufacturers, polypropylene, polyethylene and isobutylene, as well as their derivatives are used in the various manufacturing processes. TPO’s do not contain plasticizers.

TPO single-ply membranes are reinforced with polyester, fibreglass or a combination of both fabrics. Membrane reinforcement provides dimensional stability as well as strength to resist in service stresses. Membrane thicknesses range from 1.14 mm (45 mils) to 1.52 mm (60 mils), and approvals from Factory Mutual (FM), UL and ULC may be available depending on the manufacturer.

TPO membranes must be applied in conformance with RGC Guarantee Standards (Section 2.1.3C) and the membrane manufacturer’s printed instructions.

Country of Origin: U.S.A.

Country of Manufacture: U.S.A.

Year First Installed
B.C.: 2010
Canada: 1992
U.S.A.: 2005

DESCRIPTION

The primary component of the Mule-Hide TPO roofing systems is the Mule-Hide TPO (Thermoplastic Polyolefin) membrane. The TPO membrane is a polyester reinforced, 1.11 mm (.045”), 1.52 mm (.060”) or 2 mm (.080”) thick heat weldable membrane. High breaking strength, tear and puncture resistance is achieved by encapsulating a strong, woven, polyester fabric between the top and bottom plies. The TPO membrane is formulated to provide long term ultraviolet and ozone resistance. It is an environmentally friendly membrane as it is compounded without chlorine.

Mule-Hide TPO membranes are available in widths of 2.44 m (8’), 3.05 m (10’) and 3.66 m (12’). Standard roll lengths are 30.48 m (100’). The Mule-Hide TPO roofing systems may be installed ballasted, mechanically attached or fully adhered. Seaming of the TPO membrane is completed by hot air welding.

PART 1 - GENERAL
The roofing assembly / material information published in the RCABC Roofing Practices Manual 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 SYSTEM DESCRIPTIONS/RANGE OF APPLICATIONS
.1 Mule-Hide TPO Roofing Systems may be used on commercial, industrial and institutional projects for new construction, recover or reroofing applications.
.2 As a ballasted roofing system the TPO membrane is loose-laid over an acceptable substrate. The TPO membrane is secured to the roof substrate by the application of acceptable gravel ballast applied over the membrane. Mechanical attachment of the roof is only required at the perimeter edge, base of parapet walls, curbs and other vertical surfaces. Refer to the Mule-Hide published TPO details for securement of other various roof penetrations.
.3 As a fully-adhered roofing system the TPO membrane is adhered to an acceptable substrate with adhesive. Ballast is not used with a fully adhered system. Mechanical attachment of the roof is only required at the perimeter edge, base of parapet walls, curbs and other vertical surfaces. Refer to the Mule-Hide TPO details for securement of other various roof penetrations.
.4 As a mechanically attached roofing system the TPO membrane is secured to the roof deck by use of mechanical fasteners. Adhesives and ballast are not used with a mechanically attached roof system for attachment of the membrane to horizontal surfaces. Mechanical attachment of the roof is also required at the perimeter edge, base of parapet walls, curbs and other vertical surfaces. Refer to the Mule-Hide TPO details for securement around other various roof penetrations.
.5 Mechanically attached and fully adhered roof systems may be used on facilities which have roof configurations such as domes or barrels, or where the structure cannot carry the load of a ballasted system.
1.2 DELIVERY, STORAGE, HANDLING, PROTECTION
.1 Deliver and store materials in undamaged, original packages and containers with manufacturer's labels, seals intact and protected from damages due to weather or other causes.
.2 Store membrane rolls flat in dry protected areas. Store materials such as solvent-based adhesives and sealants in accordance with local requirements for storage of flammable materials. Other accessories should be stored in clean, dry areas on pallets protected from the elements.

PART 3 - EXECUTION
3.1 PREPARATION
.1 Ensure the proper decking for the substrate is provided for the roofing system selected.
.2 All substrate surfaces to receive the TPO membrane are clean, dry, smooth, and free of sharp edges, fins, loose or foreign materials, oil, grease, and other materials, which may damage the membrane.
.3 Ensure deck penetrations are installed prior to installing membrane.
.4 Ensure parapet substrates are suitable for adhering membrane flashings.
.5 Insulation must be compatible with roof membrane systems.
.6 When applying TPO directly over a wood deck ensure plywood substrates are secured with screws. If decks are nailed, an acceptable protection course must be provided over the deck.
3.2 MEMBRANE APPLICATION
.1 When installing TPO always install the sheets to avoid water from penetrating under the membrane.
.2 When seaming, all sheets must be shingled over the lower sheet to prevent backwater seams.
.3 Only install as much product as can be made watertight by the end of the working day.
.4 Fully-adhered:
.1 Position sheets to allow a minimum of a 50 mm (2”) overlap. Fold the membrane back evenly onto itself to expose half of underside; ensure the fold is smooth and the sheet lays without wrinkles.
.2 Apply TPO bonding adhesive evenly without globs or puddles, to both the exposed underside of the EPDM membrane and the substrate simultaneously. Use a standard 225mm (9") wide, solvent-resistant, short nap paint roller. DO NOT APPLY BONDING ADHESIVE TO SEAM AREA.
.3 Allow bonding adhesive to dry until tacky but not sticky or stringy at the touch of a clean, dry finger.
.4 Roll coated sheet of membrane into the coated substrate slowly and evenly avoiding wrinkles and air pockets. Brush down the mating surfaces with a stiff push broom to ensure proper contact.
.5 Fold back the remaining half of the sheet and repeat the process to adhere the remaining portion of the TPO sheet.
.6 Install the adjoin sheets in the same manner making sure not to create any backwater seams. Overlap adjoining edges of sheets a minimum of 50 mm (2”) for seaming.
.7 Follow procedures outlined in 3.3 for seaming and 3.4 for flashing.
.5 Ballasted System:
.1 Position sheets overlapping edges a minimum of 50 mm (2”) making sure that no backwater seams occur.
.2 Follow procedures outlined in 3.3 for seaming and 3.4 for flashing.
.3 Install smooth river washed gravel ASTM No.4 (D448 using C136 test method) at a rate adequate to provide proper protection against wind uplift; minimum 50 kg/meters squared (10 lb/sq ft).
.4 Alternative ballast: Concrete pavers 610 mm x 610 mm x 50 mm (minimum 2' x 2' x 2") may be installed over an acceptable protection mat as membrane ballast.
.5 Alternative ballast: Use an approved protection mat and crushed stone (same sizes as smooth, river washed stone).
.6 Mechanically Attached System:

DESCRIPTION

The main component of the roofing system is the Firestone Ultra-Ply TPO Membrane, a tough flexible membrane based on Polypropylene and Ethylene Propylene Rubber compounding. The sheet is constructed with a weft(woven)-inserted scrim that provides for superior tear propagation resistance. Dimensional stability and increased puncture resistance over similar thermo-fusible membranes make UltraPly TPO ideally suited for many commercial/industrial roofing applications. Subsequent Ultra-Ply TPO panels are heat welded together to form a continuous sheet.

PART 1 - GENERAL
The roofing assembly / material information published in the RGC Roofing Practices Manual does NOT represent a complete set of the manufacturers published data, nor does it represent a detailed specification. The preparation of a detailed specification is the responsibility of the design authority.
1.1 RANGE OF APPLICATIONS

.1 Firestone UltraPly TPO Systems are for use over all types of roof decks in commercial, institutional, industrial, low sloped roofing applications. System requirements may vary by deck. .2 As a loose-laid system, UltraPly TPO is laid over a free-floating insulation or separation layer, and held in place by gravel ballast. .3 A Fully Adhered System uses a mechanically attached substrate (insulation, separation layer, or pre-approved deck type) and adhesive to bond the membrane to it. The system is used on facilities where loose-laid systems would be considered inappropriate because of building height, location, or loading requirements. .4 A Mechanically Attached System uses a mechanically attached substrate (insulation, separation layer, or pre-approved deck type) and barbed disc and screws to secure the membrane at pre-determined rates. The system is used on facilities where loose-laid systems would be considered inappropriate because of building height, location, or loading requirements and where fully adhered systems would be considered inappropriate because of climatic conditions (cold weather application). .5 An Inductive Welded Mechanically Attached System uses TPO coated insulation fastener plates that the TPO membrane is welded to with an inductive process from the top side of the membrane.

1.2 DELIVERY, STORAGE AND HANDLING
.1 Deliver and store materials in undamaged, original containers with manufacturer’s label and seals intact. Follow manufacturer’s recommendations for site storage of materials.
.2 Store membrane rolls flat. Take precautions so as not to overload any area of the roof deck.
.3 Protect adhesives from freezing weather conditions. Protect insulation materials from rain.
1.3 SITE CONDITIONS
.1 Slope Limitations:
Minimum slope: Dead flat
Maximum sloped (Adhered): Vertical
Maximum slope (Ballasted): 2:12
Maximum slope (Mechanically Fastened): 6:12
.2 Application temperatures: (temperatures limited by handling of materials, particularly adhesives; special application techniques are need outside this range:
  • Minimum ambient temperature 4.4°C (40°F)
  • Maximum ambient temperature 40°C (104°F)
.3 Chemical incompatibilities
.1 Asphalt, coal tar base, oil based or plastic roof cement resaturated roof products are not to be used in direct contact with the UltraPly TPO System.
