Title:
EXTERIOR SHEATHING WEATHER BARRIER CONSTRUCTION AND METHOD OF MANUFACTURE
Document Type and Number:
WIPO Patent Application WO2007004066
Kind Code:
A9
Abstract:
A gypsum board panel having two facing main surfaces and machine edge surfaces, the board including an outer gypsum layer in which a polymer additive has been entrained, and the machine edges being shaped to have a three-dimensional feature, such that the features are complementary, and one machine edge surface can engage the complementary surface of the machine edge of an adjacent gypsum board panel. The three-dimensional features may include a triangular, in cross- section, ridge, or a rectangular ledge, or a concave edge, with a corresponding complementary groove or depression on the opposed edge for engagement with the edge of an adjacent board. A plurality of fastener plugs, taking the form of, for example strips or dots, can be disposed on the outer facing surface of the board to provide an entry point for penetration of a fastener, such as a nail or screw, and a layer of sheathing material, for example a covering polymeric coating, is optionally disposed over the outer board panel surface to further enhance the moisture repellent properties of the board.
