Abstract
A laminate of foil and kraft paper is adhered to the upper face of fiber glass insulation so that the exposed foil reflects radiant heat entering the attic through the roof of a building structure. Relatively thick kraft paper supports the very thin layer of foil without causing a fire hazard due to the use of an inorganic adhesive, such as sodium silicate, to bond the two together and also due to the use of a fire retardant water-based adhesive to bond the foil-kraft laminate to the fiber glass. The laminate is preferably perforated to prevent it from functioning as a vapor barrier.
