Creased facing material for insulation product applications

摘要

An insulation product is provided comprising an insulation mat having first and second major surfaces and a pair of side portions. A 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. The facing layer can also have a crease in the machine direction that allows the facing layer to be separated by hand along the machine direction. The insulation mat may also be separable in the machine direction, and the separable portions of the insulation mat may substantially align with the crease in the facing layer to allow the facing and insulation to be separated together.
