An insulation board comprising a plastic foam layer which is covered by at least one facing sheet, the facing sheet comprising 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.
