Pittsburgh — PPG Industries’ new high-performance glass combines the solar control performance of Solarban 80 low-emissivity (low-E) glass with the company’s new blue-green Optiblue glass. The result is an architectural glass with a metallic gray-green exterior tint and a neutral gray interior appearance. In a standard one-inch insulating glass unit, Solarban 80 Optiblue glass produces a solar heat gain coefficient (SHGC) of 0.23 and visible light transmittance (VLT) of 34 percent. This results in a light-to-solar gain (LSG) ratio of 1.48, which far exceeds the U.S. Department of Energy’s 1.25 LSG threshold for spectrally selective glass, the company reports.www.ppgideascapes.com .
