Stone utilization and fabrication has evolved rapidly in recent years. Originally, stone was a massive structural building material. Today, with the use of sophisticated cutting techniques, stone can be a thin veneer cladding for building exteriors. To utilize this thin stone product a number of prefabricated panel systems have appeared including the Cygnus steel/silicone diaphragm system. The Cygnus system utilizes structural silicone to uniformly distribute the exterior dead and dynamic loads over a galvanized steel diaphragm panel. This patented, proprietary manufactured system provides a tough, durable, light-weight exterior skin utilizing stone, tile, aluminum, or glass exterior cladding material.
