PALO ALTO, Calif.--(Southwall Technologies Inc. (NASDAQ:SWTX), the worldwide innovator of energy-saving films and glass products, today announced the world’s highest performing insulating glass (IG). The new Heat Mirror® “Quad-Cavity” R20 IG achieves a remarkable 0.05 center of glass U-factor (R20 insulating value) at the same weight as standard dual-pane IG, enabling a new generation of zero-energy windows.)--
“Heat Mirror multi-cavity technology, with center of glass performance ranging from R6 to R20, enables windows to outperform walls and become net-energy-gainers in a properly designed building or home.”
According to studies conducted by Lawrence Berkeley National Laboratory funded by the U.S. Department of Energy, “superwindows” − windows with at least R8 total unit insulating performance and moderate solar heat gain − can become more energy-efficient than insulated walls due to the added benefit of passive solar heating, in which heat from the sun is used to further reduce the heating load on the HVAC system. Unlike walls, highly-insulating windows can actually achieve a net energy gain by admitting more heat from the sun than they lose through conduction.
The Quad-Cavity R20 product suspends three lightweight Heat Mirror films within the IG unit, creating four independent and super-insulating airspaces, also called cavities. When configured in a 1-3/4” overall IG unit thickness with Krypton gas fill and low-emissivity (“low-e”) coatings on the second and tenth glass surfaces, the Quad-Cavity product meets a 0.05 center of glass U-factor and 0.09 full-unit U-factor for a typical light commercial fixed fiberglass window. Different combinations of film and low-e glass can be used to optimize performance for either maximum solar heating in cold climates or maximum solar shading in warm climates.
“Our lightweight Quad-Cavity R20 product raises the performance bar for insulating glass,” said Bruce Lang, President of Southwall Insulating Glass. “Heat Mirror multi-cavity technology, with center of glass performance ranging from R6 to R20, enables windows to outperform walls and become net-energy-gainers in a properly designed building or home.”

About Heat Mirror Suspended Film Technology
Heat Mirror film technology utilizes nanoscale metal coatings to reflect heat back to its source and improve the insulating performance of glass. One or more lightweight Heat Mirror films can be suspended inside of an insulating glass unit to create two, three or even four super-insulating cavities without adding weight. Used in conjunction with low-e glass and argon or krypton gas fill, Heat Mirror insulating glass combines the best of film-based and glass-based technologies to create "super glass" with insulating performance up to R-20 and optimum solar shading.
