Patent ID: 8132381

Claim:
An insulated building system comprising: a plurality of wall cavities defined between wall studs that are spaced apart by a known nominal width; and insulation batts positioned within the wall cavities, the insulation batts including: an elongated blanket of fibrous insulation material entirely positioned within the wall cavities, the elongated blanket having a face portion and edges defining a blanket width that is within the range of from about 102 percent to about 107 percent of the known nominal width of the plurality of insulation wall cavities; and a facing material attached to the face portion of the elongated blanket of fibrous insulation material, the facing having a width that is substantially equal to the width of the blanket; wherein the insulation batts have a stiffness characterized by an angle measurement that measures the amount of deflection of the insulation products as the insulation batts are draped over a support located perpendicular to the longitudinal center axis of the insulation product, wherein the stiffness measurement is within the range from about 15 degrees to about 35 degrees.
