Abstract:
A method for installing an insulation product comprising:providing an insulation product comprising an elongated conformable body of fibrous insulation material, with the conformable body of fibrous insulation having a facing adhered to a front major surface of the conformable body, wherein the facing is bonded to the insulation material with sufficient strength to provide product integrity to the insulation product when cut lengthwise, wherein the fibrous insulation material is expansible so that it can be expanded to an unconstrained high loft thickness, and so that when it is placed in an insulation cavity having a thickness less than or equal to the unconstrained high loft thickness it can be expanded to fill the insulation cavity, and wherein the fibrous insulation material has a resistance to compression less than about 1.0 pounds per square foot when compressed to a thickness of about 40 percent of the unconstrained high loft thickness;selecting an insulation cavity from a group of insulation cavities having thicknesses within the range of a minimum of at least about 40 percent of the unconstrained high loft thickness to a maximum of about the unconstrained high loft thickness; andinstalling the insulation product in a narrow insulation cavity having a width, by:longitudinally splitting the insulation product to create a longitudinal portion of the insulation product that is wider than the width of the narrow insulation cavity, the longitudinal portion having a first side edge with a flange and a second side edge without a flange, the second side edge having a portion of the elongated conformable body of fibrous insulation material associated with it;installing the longitudinal portion in the narrow insulation cavity by attaching the first side edge with a flange to a wall stud; andforcing the portion of the conformable body of fibrous insulation material associated with the second side edge into the narrow insulation cavity, thereby creating a new flange.
