Abstract:
1. A blanket of fibrous building insulation for installation in openings between studs, beams, rafters or like spaced-apart structural members that are evenly spaced-apart as well as between structural members that are irregularly spaced-apart, with cutting guidelines for use in providing visual guidelines for cutting the blanket to size to accommodate irregular spaces between spaced-apart structural members, comprising: (a) a fibrous insulation layer of a predetermined thickness having opposite first and second insulation surfaces between side surfaces that are spaced apart a given dimension, which first and second insulation surfaces define said predetermined thickness; (b) a thin facing sheet having first and second sheet surfaces spaced apart a dimension that is substantially less than the predetermined thickness determined by the spacing apart of the insulation first and second surfaces, with the first sheet surface thereof disposed on a second insulation surface of the insulation layer; (c) a thin adhesive layer, substantially thinner than the thickness of the insulation layer, disposed between and securing the first sheet surface of the facing sheet to the second insulation surface of the insulation layer; (d) a grid of perforations through the facing sheet; (e) spots of adhesive visible through the perforations, at the second sheet surface of the facing sheet; (f) the grid of perforations comprising means defining generally straight, predetermined cut lines for cutting the facing sheet and insulation in accordance with a pattern defined by at least some of said spots of adhesive; whereby (g) the blanket of insulation may readily be cut along a line of said spots of adhesive to accommodate spaces between spaced-apart structural members of lesser spacing than said given dimension.
