ABSTRACT OF THE DISCLOSURE This invention relates to a new composite structure suitable for use as a roof or wall of a building. The structure comprises an interior substrate, a layer of rigid insulation having an insulating ability at least equal to one inch of rigid urethane foam, and an adhesive layer bonding the insulation to the sub- strate. A layer of cementitious material at least one sixteenth inch thick is adhered to the insulation and an exterior layer of the dried residue of a polymer-rich latex coating composition, at least 2 to 4 mils thick is applied to maintain the adhesion of the layer to the cementitious material. This structure demon- strates improved resistance to penetration by fired which may start on the interior side of a building while at the same time, exhibits excellent water resistance, when compared to the structures of the prior art.
