Abstract
An insulation product is provided comprising an insulation mat comprising randomly oriented fibers. The mat has first and second major surfaces and a pair of side portions. A vapor retardant facing layer is bonded to at least one of the major surfaces of the mat. The facing layer has a fiber orientation such that the facing layer has a ratio of machine direction tensile strength to cross machine direction tensile strength which permits the facing layer to be separated by hand along a substantially straight line selected in the machine direction.
