FACED FIBERGLASS BOARD WITH IMPROVED SURFACE TOUGHNESS

摘要

An insulation product (100) is provided comprising a sheet (10) of randomly oriented fibers bonded by a binder. The sheet (10) has first and second major surfaces (11, 12) and a pair of side portions (13, 14). A facing layer (16, 18) is bonded to at least one of the major surfaces (11, 12). A region of the sheet (10) proximate to the facing layer (16, 18) is more puncture resistant than a remainder of the sheet (10).
