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 0.0015" white metallized polypropylene film laminated to a fiberglass/polyester blend fabric with a fire resistant adhesive. The resulting facing shall have a water vapor transmission rate of 0.02 US perm (ASTM E96, Procedure A), a beach puncture of 650 scale units and a mullen burst of 250 psi. Tensile strength shall be 195# in the machine direction and 150# in the cross-machine direction.
