Pre-cut fibrous insulation for custom fitting building cavities of different widths

摘要

A fibrous insulation blanket is pre-cut for custom fitting the insulation blanket into wall, floor, ceiling and roof cavities of different widths formed by the framework of a building. The insulation blanket has one or more pairs of longitudinally extending cuts in the major surfaces of the blanket. Each pair of cut(s) leaves a separable connector within the blanket between adjacent sections of the insulation blanket whereby the blanket can be handled as a unit for insulating a cavity having a width about equal to the width of the blanket or easily separated or torn apart by hand at a separable connector for insulating a cavity having a lesser width. A major surface of the blanket may have a facing bonded thereto that is separable by hand along the cut(s) in the major surface to facilitate separating the blanket by hand.
