Abstract
Panels for the construction of a moistureproof back-up wall around the exterior perimeter of a building adjoining and spaced inwardly from a moisture permeable exterior wall include a substantially rigid, non-load bearing, moisture-permeable core having two opposing major planar outer sides and four side edges connecting the two opposing major outer sides. A moistureproofing material layer is applied completely covering one of the two opposing major planar outer sides of the core and extending continuously from that side of the core beyond one of the four side edges of the core. An adhesive surface is provided facing the core on the extending portion of the moistureproof material layer. A removable strip applied to the adhesive surface protects the adhesiveness of the surface prior to installation. The moistureproofing layer may be a solid, integral flexible sheet of a suitable material such as plastic or metal, an integral layer of a moistureproof material not having sufficient tensile strength to support itself in use, such as an asphalt based material, or a combination of the two.
