ABSTRACT:
A segmented, encapsulated insulation assembly preferably includes a blanket of fibrous insulation having a plurality of longitudinally spaced apart, transversely extending cuts therein. The cuts divide the fibrous insulation into segments and weaken the fibrous insulation to permit the fibrous insulation to be selectively separated at any of the cuts. The fibrous insulation is encapsulated within an envelope having weakened transverse tear lines that divide the envelope into envelope segments. The transverse tear lines in the envelope overlay the cuts in the fibrous insulation to permit the envelope to be separated at the cuts thereby forming a plurality of encapsulated fibrous insulation modules. One or more of the encapsulated fibrous insulation modules can be selectively separated from the segmented, encapsulated fibrous insulation assembly to form an insulation panel of a desired length to insulate a cavity. Preferably, the surfaces of the fibrous insulation cuts are treated with a dust suppressant to reduce or prevent dust and/or fiber release from these surfaces.
