Abstract

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. Preferably, the facing has tabs for securing the insulation blanket to framing members and when one or more perforated lines are used in the facing, the perforations of the perforated line(s) in the facing are closed by the bonding agent bonding the facing to the blanket so that the facing functions as a vapor barrier in spite of the perforations.
