Manufacturer: <b>HAL INDUSTRIES INC.</b>

Contact Address: See Membership List in Section 1.

Product Group: <b>POLYESTER FELTS, BUILT-UP ROOF</b>

Country of Origin: Canada of Manufacture: Canada, U.S.A.

Year First Installed: B.C.: 1984 

Canada: 1984

===Description===
POLYMAX felts consist of engineered polyester fabrics which have been saturated with roofing grade asphaltic bitumen. These felts are designed to provide long-term performance in most climatic conditions and are applied using conventional roofing equipment and methods.

POLYMAX polyester felts are available with either 180 g / meters squared or 250 g / meters squared spun bond polyester reinforcing mats. The polyester provides an inorganic mat with proven tensile strength and tear and puncture resistance.

====GENERAL====
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.
## <u>SYSTEM DESCRIPTIONS</u>
### Polymax System: install three plies of POLYMAX 180 or POLYMAX 250 felt in full moppings of hot asphalt; surface with pour coat and gravel to <i>RGC Guarantee Standards</i>; qualifies for an RGC five (5) or ten (10) year Guarantee (with compliance to <i>RGC Guarantee Standards</i>).
### Range of application: POLYMAX built-up roofing systems can be used wherever conventional built-up felt and asphalt roofing is presently used.
## <u>DELIVERY, STORAGE, AND HANDLING</u>
### Deliver and store materials in original packages and containers with manufacturer's seals and label intact.
### Keep roofing materials dry; protect from adverse weather conditions.
### Store rolls on end.
## <u>SITE CONDITIONS</u>
### Slope limitations:
####* minimum recommended slope 1:50 (1 / 4&quot; in 12&quot;)
####* backnail each felt on slopes over 1:12 (1&quot; in 12&quot;)
## <u>STANDARDS AND APPROVALS</u>
###Tested to <i>applicable portions only</i> of CGSB 37-GP-56M by Intertek Testing Services.
## <u>MANUFACTURER'S SERVICES</u>
### Applicator training: available

## <u>ANCILLARY PRODUCTS</u>
### Asphalt: conform to CSA A123.4M Type 3 asphalt.
### Base sheet: asphalt-coated base sheet conforming to CSA A123.2 Type CF; or Hal Industries Inc. No. 30 organic felt.
### Mineral surfaced roofing: 2 mm granulated SBS
### Gravel:  to<i> RGC Guarantee Standards</i>.
====EXECUTION====
## <u>PREPARATION</u>
### Prepare decks according to good roofing practices; decks should be clean, dry, and free of voids or cracks; ensure concrete decks are cured.
### Ensure wood blocking, curbs, and cant strips are solidly set and reglets and nailing strips are in place.
### Wood decks: ensure deck is tightly nailed; cover splits and knot holes with galvanized sheet metal, nailed securely.
## <u>INSULATION AND INSULATION OVERLAY</u>
### Mechanically fasten insulation over nailable decks according to <i>RGC Guarantee Standards</i>.
### Embed insulation in a 1.5 kg / m<sup>2</sup> (30 lb / square) mopping of hot asphalt over non-nailable decks.
### Install accepted insulation overlay board as an insulation overlay, <b>where required</b>, according to<i> RGC Guarantee Standards</i>.
### Tape insulation joints where an insulation overlay is not used.
### Install nailing strips on slopes over 1:12 (1&quot; in 12&quot;) at 600 mm (24&quot;) o / c.
## <u>POLYMAX 180 OR 250 THREE-PLY BUILT-UP ROOF MEMBRANE</u>
##: [qualifies for a Five (5) or Ten (10) year RoofStar Guarantee]
### Start at low point and at right angles to slope.
### <b>Ensure asphalt temperature does not exceed +237&deg;C (+470&deg;F) at point of application or severe deformation of the felt may occur.</b>
### Mop three plies POLYMAX 180 or 250 roofing felt in 1.5 to 1.7 kg / m<sup>2</sup> (30 to 35 lb / square) hot asphalt per ply; ensure a puddle of asphalt precedes the roll.
### Firmly broom or dry mop felt surface <b>while asphalt is hot</b>, eliminating voids and forcing membrane into hot asphalt.
### Follow lap lines on felt; stagger end laps.
### Backnail each mopped felt where slopes exceed 1:12 (1&quot; in 12&quot;), 600 mm (24&quot;) o / c.
### Install membrane flashing of two plies POLYMAX 180 or POLYMAX 250 and one ply mineral surfaced roofing in full moppings of hot asphalt; mould POLYMAX into corners and glaze coat surface; install mineral surfaced cap sheet where membrane flashing will be exposed.
## <u>POUR COAT AND GRAVEL</u>
### Install asphalt pour coat and gravel according to <i>RGC Guarantee Standards</i> for a built-up roof membrane.
## <u>PROTECTED MEMBRANE OR MODIFIED PROTECTED MEMBRANE ROOF ASSEMBLY</u>
### Loose lay CGSB 51-GP-20M Type 4 extruded polystyrene rigid insulation over completed membrane; butt boards tightly together.
### Install filter fabric over insulation surfaces, in shingle fashion, in direction of slopes, lapping 300 mm (12&quot;).
### Install gravel or pavers over insulation. Refer to insulation manufacturer's latest printed recommendation for gravel rates.
