Abstract
An insulation product is provided comprising a sheet of randomly oriented fibers bonded by a binder. The sheet has first and second major surfaces and a pair of side portions. A facing layer is bonded to at least one of the major surfaces. A region of the sheet proximate to the facing layer is more puncture resistant than a remainder of the sheet.
