PPG's Triple-silver-coated Solarban 70XL glass Sets a Standard for Solar Control Performance

Published on 2011-06-09. Author : SpecialChem

PITTSBURGH -- PPG Industries announced that shipments of SOLARBAN® 70XL glass, the industry's first triple-silver-coated, solar control, low-emissivity (low-e) glass, have surpassed 94 million square feet.

Solarban 70XL glass, which was introduced at the 2005 Green Build International Conference and Expo, set a new standard for solar control performance for architectural glasses with a clear-glass appearance. Featuring a solar heat gain coefficient (SHGC) of 0.27 and visible light transmittance (VLT) of 64 percent, Solarban 70XL glass has a light-to-solar gain (LSG) ratio of 2.37 that remains unmatched six years after its introduction.

Glenn Miner, PPG director, construction, flat glass, said that Solarban 70XL glass has been installed on more than 300 commercial buildings. Had the same buildings been glazed with double-silver, low-e coated glass, he estimates that owners would have spent $81 million more on heating- and cooling-related energy. Those savings, which average more than $25 million per building, do not consider additional capital cost reductions that owners may have realized by installing smaller, less-expensive HVAC units.

Miner said that Solarban 70XL glass is the leading choice for architects and building owners seeking to optimize energy performance while maintaining a true, transparent-glass appearance. "Other companies have introduced competitive triple-silver coated glasses, but in our opinion, none offer the balance of clarity and solar control that Solarban 70XL glass does," he said. "That is due to the proprietary formulation of both the Solarban 70XL glass coating and the glass substrate."

Solarban 70XL glass has been installed on more than 100 Leadership in Energy and Environmental Design (LEED)-certified buildings, including several that have earned green building of the year awards from the American Institute of Architects' (AIA) Committee on the Environment (COTE).
