PPG INDUSTRIES: Solar-Control, Low-Emissivity Glass
PPG Industries has introduced Solarban® 90 glass, a solar control, low-emissivity (low-e) glass that reportedly combines industry-leading solar control performance with a true neutral-reflective clear-glass aesthetic. Solarban 90 glass is reportedly engineered with refinements to PPG’s triple-silver coating technology to offer architects a product that outperforms Solarban 70 XL glass while balancing visible light transmittance (VLT) and helping manage glare.
The neutral-reflective appearance of Solarban 90 glass was developed with input from architects. “The look of clear glass has always been popular with building designers for its neutral color, muted reflectivity and ability to transmit daylight,” said Glenn T. Miner, director of construction, flat glass. “Now with Solarban 90 glass, they can specify a glass product that delivers all those attributes together with a solar heat gain coefficient exceeding that of Solarban 70XL glass.”
Combined with clear glass in a standard 1-in. insulating glass unit (IGU), Solarban 90 glass reportedly has a solar heat gain coefficient (SHGC) of 0.23, a 15% improvement over Solarban 70XL glass. The same configuration produces VLT of 51% and a light-to-solar-gain (LSG) ratio of 2.22. Interior and exterior reflectance rates are 12% and 19%, respectively.
The solar control performance of Solarban 90 glass reportedly supports the use of smaller heating, ventilation, and air conditioning (HVAC) systems to reduce initial capital expenditures and long-term cooling costs. It also enables architects to design buildings with larger expanses of glass to promote daylighting, diminish the need for artificial lighting, and connect building occupants to the outdoors. Solarban 90 glass meets requirements of the CRADLE TO CRADLE CERTIFIED™ program at the Bronze level.
