The Attachments Energy Rating Council certified six new commercial secondary window systems: four interior storm window products from Larson Manufacturing, two interior and two exterior products from Quanta, and two window insert products from Indow Windows.
Quanta, a manufacturer and marketer of architectural Low-E storm windows, has certified The QuantaPanel 600 Series, which installs on the interior, and the QuantaPanel 700 Series, which installs on the exterior, with AERC. QuantaPanel Insulating Glass Systems are used in single-family homes, as well as commercial and multifamily buildings.
Larson Manufacturing has certified four interior storm window models with AERC: I200E, I500E, and I600E single-hung, fixed, and sliding storm windows in the ComfortSeal product line, along with the I900C Commercial Insider Window, all with low-E glass. Larson’s certified low-E storm windows are used as an additional layer of glass on the interior or the exterior of existing windows to provide more comfortable spaces.
Indow has certified its Standard and Acoustic Grade Window Inserts. Indow inserts are used by commercial customers to block drafts completely and reduce noise by up to 70 percent, leading to a 20 percent reduction in heating and cooling bills, according to the company.
“AERC is pleased to welcome these three manufacturers to the Commercial Secondary Window program,” says Ralph Vasami, executive director of AERC. “Indow, Larson and Quanta are leaders in the industry, developing products that will help consumers save energy and contribute to achieving the efficiency goals of our utility and research partners.”
AERC launched the Commercial Secondary Window program late last year alongside its existing residential products certification program. The commercial secondary windows program adopted similar performance metrics used by AERC’s residential program including U-factor, solar heat gain coefficient, visual transmittance and air leakage.
