Abstract
An insulation board comprising a plastic foam layer which is covered by at least one facer, the facer comprising (a) a sheet of glass fibers bonded to each other by a bonding agent, the fibers and bonding agent being coated with a non-wicking agent, whereby, although the fibrous facing sheet is porous to permit venting of gases and vapors, it is substantially liquid-repellant to prevent bleed through by various types of liquids, and (b) a scrim between the facing sheet and the plastic foam layer, the scrim comprising a sheet, preferably made of glass fibers similar to the facing sheet, and having a pattern of glass strands over one face thereof.
