US Patent 8245472 Building facade construction system and methods therefor

A building façade system adapted to be installed onto an exposed surface of a building and provide a substrate for installation of façade elements (e.g., stone, stucco and the like). The system preferably provides a corrosion-resistant structure adapted to withstand extended environmental exposure. In general, the system includes a highly porous three dimensional matrix filamentous polymeric mat and a fiberglass mesh layer associated therewith. Collectively, the polymeric mat and fiberglass mesh layer are adapted to be installed onto an exposed building wall and provide a substrate onto which desired façade elements may be installed.
