An insulation product (100, 101) is provided comprising a low density mat (1 0, 10a, l0b, 111) containing randomly oriented inorganic fibers bonded by a hea t cured binder. The fibers comprise fibers (20) with a melting temperature abo ve the curing temperature of the binder. The fibers comprise fibers (21) with a melting temperature below the curing temperature. The mat (10, 10a, 10b, 111 ) has first and second major surfaces (11, 12) and a pair of side portions (14 , 15). A nonwoven sheet (13, 13a, 13b) is bonded to the first major surface (11). The nonwoven sheet (13, 13 a, 13b) comprises randomly oriented glass fibers and is bonded to the first major surface (11) by the heat cured binde r. |
