Abstract
Abstract A composite structure is disclosed, wherein the structure includes an interior substrate or facing, a layer of rigid insulation, and an exterior facing or cementitious layer, with an adhesive adhering such insulation at least to the interior substrate or facing, with an exterior waterproofing layer of the dried residue of a latex polymer-coating composition being adhered to the exterior of the composite structure or panel. The waterproofing coating layer contains a film-forming polymer which is an acrylic polymer or a vinyl polymer, and has a Mar Elasticity Value of at least 1. The composite structure or insulating structural panel of the present invention may be used as the wall or the roof of a building.
