发明名称 SEGMENTED, ENCAPSULATED INSULATION ASSEMBLY
摘要 A segmented, encapsulated insulation assembly (20) preferably includes a blanket (42) of fibrous insulation (22) having a plurality of longitudinally spaced apart, transversely extending cuts (28) therein. The cuts (28) divide the fibrous insulation (22) into segments (26) and weaken the fibrous insulation (22) to permit the fibrous insulation (22) to be selectively separated at any of the cuts (28). The fibrous insulation (22) is encapsulated within an envelope (24) having weakened transverse tear lines (30) that divide the envelope (24) into envelope segments. The transverse tear lines (30) in the envelope (24) overlay the cuts (28) in the fibrous insulation (22) to permit the envelope (24) to be separated at the cuts (28) thereby forming a plurality of encapsulated fibrous insulation modules (26). One or more of the encapsulated fibrous insulation modules (26) can be selectively separated from the segmented, encapsulated fibrous insulation assembly (20) to form an insulation panel of desired length to insulate a cavity. Preferably, the surfaces (36) of the fibrous insulation cuts (28) are treated with a dust suppressant to reduce or prevent dust and/or fiber release from these surfaces (36).
