METHOD AND APPARATUS FOR CONTAINING INSULATION USING A BARRIER ASSEMBLY

摘要

An apparatus and a method are provided to retain loose fill or particulate insulation between the outer and inner walls of a structure. The apparatus comprises a barrier assembly comprised of laminate layers of a netting material and a polypropylene material both with some degree of flexibility. The netting material is constructed to strengthen the polypropylene material and bulge slightly when a desired amount of insulation has been received and positioned within an enclosed space of the wall structure. The polypropylene material is constructed to be substantially air permeable but substantially impermeable to the passage of all size fractions of insulating fibers and other particulates typically found in insulation materials.
