UNIVERSAL INSULATION PRODUCT AND METHOD FOR INSTALLING

摘要

An insulation product (60) includes an elongated conformable body (62) of fibrous insulation having front and rear major surfaces (66, 74) and two elongated side surfaces (72). A facing (64) is adhered to the front major surface (66) of the conformable body (62), the facing (64) having sufficient tensile strength to withstand a pressure, without tearing, of about 1.0 pound per square foot from the fibrous insulation in a wall cavity (16, 18, 20) defined by wall studs (14), when the facing (64) is adhered to the wall studs (14). The facing (64) is bonded to the conformable body (62) with sufficient strength to provide product integrity to the insulation product (60) when it is cut lengthwise. The insulation product (60) can be expanded when unconstrained to a high loft thickness so that when the batt (60) is placed in an insulation cavity having a thickness less than or equal to the high loft thickness, the insulation product (60) can be expanded to fill the insulation cavity (16, 18, 20). The fibrous insulation material has a resistence to compression less than about 1.0 pound per square foot when compressed to a thickness of about 40 percent the unconstrained high loft thickness.
