FLANGED INSULATION ASSEMBLY AND METHOD OF MAKING
An insulation assembly includes an elongated batt of fibrous insulation material (52) having two opposed major surfaces (54, 56), where the batt (52) has a first facing (60) secured on its first major surface (54). The first facing (60) extends beyond the side edges of the batt (52) to form opposed flanges (32) suitable for attaching the insulation assembly (70) to a building structure. The batt (52) has a second facing (62) secured on its second major surface (56), with the second facing (62) extending beyond the side edges of the batt (52) to form opposed flanges (32) suitable for attaching the insulation assembly (70) to a building structure. The method of making an insulation assembly (70) includes moving a batt of fibrous insulation material (52) along a path, where the fibrous insulation material (52) has two opposed major surfaces (54, 56). A continuous encapsulation material (16) is applied to the pack (10), and a portion of the encapsulation material (16) is continuously gathered to form a two part fold (22). The two parts of the fold (22) are bonded together to form a flange (32) suitable for attaching the insulation assembly (70) to a building structure.
