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 E84 test method.

Facing shall be composed of 38.1 micron white coated polypropylene film, a reinforcing layer, a proprietary inner core and 12.7 micron metallized polyester film.  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), and a mullen burst of 8.4 kg/cm².  Tensile strength shall be 11.4 kN/m in the machine direction and 10.5 kN/m in the cross-machine direction
