摘要：
A method of making an insulation product is provided. An uncured or partially cured mat containing randomly oriented inorganic fibers and a heat curable binder agent is formed. The mat has a pair of side portions and a first and second major surfaces thereon. A nonwoven sheet is applied to the first major surface. The nonwoven sheet comprises randomly oriented glass fibers. The uncured or partially cured mat is heated with the nonwoven sheet, wherein the mat is cured to form a low density mat and the nonwoven sheet is bonded to the first major surface by the heat curable binder agent.
