An embossed, Slip resistant surface is provided on the polyethylene. C. Underlayment shall meet the physical properties and performance characteristics indicated: Thickness membrane: 40 mil (min) Tensile strength, membrane ASTM D 882-02 A (Die C modified): 1400 psi. Elongation, membrane ASTM D 412-06ael (Die C modified): 500%. Low temperature flexibility, ASTM D 1970-08: Unaffected at -292F (-202C) Adhesion to plywood, ASTM D 903-98(2004): 525 N/m (3 Ib/in width) Permeance (max), ASTM E 96-05: 2.9 ng/(PA x s x m2) (0.05 perms max) Material weight installed (max): 1.3 kg/m2 (0.3 Ib/ft2 max) 2010 Florida Building Code approved. ONA OR WNH > 2.03 PRECAUTIONS AND LIMITATIONS A. Installed material is slippery when wet or covered by frost. B. Release liners are very slippery. Remove from work area immediately after membrane application. C. Always wear fall protection when working on roof deck. D. Donot leave permanently exposed to sunlight. Underlayment should not be left exposed for more than thirty (30) days. E. Check with the manufacturer of the metal roofing system for any special requirements when used under metal roofing. Do no install directly under roof coverings especially sensitive to corrosion, such as zinc, and copper without providing proper ventilation. Ce EES "ee PART 3 - EXECUTION 3.01 EXAMINATION A. Examine substrates and conditions, with installer present, for compliance with the requirements in which substrates and related work are specified and to determine if other conditions affecting the performance of the insulation are satisfactory. Do not proceed with the installation of the insulation, until unsatisfactory conditions have been corrected. 3.02 INSTALLATION, GENERAL A. Comply with the insulation manufacturer's written instructions applicable to the products and applications indicated. B. Install underlayment directly on a clean, dry continuous structural deck. 1. Remove dust, dirt, loose nails and excess roofing materials. 2. Protrusions from the deck area must be removed. 3. Decks shall have no voids, damaged or unsupported areas. 4. Repair deck areas before installing the membrane. C. Apply underlayment Only in fair weather when the air, roof deck and membrane are at temperatures of 40 degrees F or higher, and / or as recommended by the manufacturer. D. Install the membrane so that all laps shed water. Always work from the low point to the high point of the roof. Apply the membrane in valleys before the membrane is applied to the eaves. Following placement along the eaves, continue application of the membrane up the roof. The membrane shali be installed horizontally. 1. Overlaps / Side laps shall be a 4" min. 2. End laps shall be a 6" min. E. Use smooth shank, electroplated galvanized nails with button caps for roofing fasteners. Hand nailing will provide a better seal than power activated nailing. If nailing of the membrane is necessary on steep slopes during hot weather, back nail and cover nails by overlapping with the next sheet. F. Repair holes, fish mouths, tears, and / or damage to membrane with a round patch of membrane extending past the damaged area a min of 6" in all directions. If fasteners are removed leaving holes in the membrane. it must be patched. The membrane may not be self-sealing at open fastener penetrations.
