ENGLISH

Fiberglass shall be as outlined in the North American Insulation Manufacturing Association (NAIMA 202-96) specification, or equal, with an R-value of ______ when not compressed.  The fiberglass shall be faced with ______, as specified below, on one side.  The composite of fiberglass and facing shall have surface burning characteristics not to exceed 25 flame spread and 50 smoke developed when tested in accordance with Underwriters Laboratories 723 test method or ASTM E 84 test method.

Facing shall be composed of 0.0003" aluminum foil with an elastomeric vapor barrier coating, a reinforcing layer and 30# kraft paper. The product shall be reinforced with a 5x5 tri-directional scrim which has a blend of fiberglass and polyester yarns. The resulting facing shall have a water vapor transmission rate of 0.02 US perm (ASTM E96, Procedure A), a beach puncture of 85 scale units and a mullen burst of 60 psi. Tensile strength shall be 55# in the machine direction and 35# in the cross-machine direction. The manufacturer’s name and product identification must be printed on the tab area of the facing.

Fiberglass shall be as outlined in the North American Insulation Manufacturing Association (formerly T.I.M.A ) specification, or P.E.B. 202 or equal, with an R-value of ______ when not compressed.  The fiberglass shall be faced on one side.  The composite of fiberglass and facing shall have surface burning characteristics not to exceed 25 flame spread and 50 smoke developed when tested in accordance with Underwriters Laboratories 723 test method or ASTM E 84 test method.

Facing shall be composed of 7.6 micron aluminum foil with an elastomeric vapor barrier coating, a reinforcing layer and 49 gm/m² kraft paper. The product shall be reinforced with a 20/100 mm x 20/100 mm tri-directional scrim which has a blend of fiberglass and polyester yarns. The resulting facing shall have a water vapor transmission rate of 1.15 ng/N·s (ASTM E96, Procedure A), a beach puncture of 2.5 Joules and a mullen burst of 4.2 kg/cm². Tensile strength shall be 9.6 kn/m in the machine direction and 6.1 kn/m in the cross-machine direction. The manufacturer’s name and product identification must be printed on the tab area of the facing.
