PITTSBURGH, January 31, 2017 — Vitro Architectural Glass has introduced Sungate^® 460 glass, a clear passive low-emissivity (low-e) glass that enables window manufacturers to achieve “Equivalent Energy Performance Values” for residential insulating glass units (IGUs) in the ENERGY STAR^® 6.0 certification standard.

Brad Boone, residential glass market manager, Vitro Architectural Glass, said Sungate^® 460 glass is engineered to help window manufacturers maximize the value of their products while enhancing their performance.

“Sungate^® 460 glass works by permitting solar energy to enter the home; then by trapping the re-radiated energy and combining it with furnace heat to reduce winter heating loads,” he explained. “When window makers fabricate an IGU with insulating gas, a warm-edge spacer and Sungate^® 460 glass positioned on the third surface, the unit can be installed with quality framing materials to reach ENERGY STAR^® mandates. That can save manufacturers money by eliminating the need to place low-e coatings on the second and fourth surfaces of the unit.”

Designed for the northern and north-central ENERGY STAR^® climate zones, Sungate^® 460 glass has a center-of-glass winter nighttime U-value of 0.26 and a solar heat gain coefficient (SHGC) of 0.58 in a standard 3-millimeter IGU.

When supplemented with quality framing and insulating spacers and gases, that center-of-glass performance can facilitate overall window U-values of 0.30 and minimum SHGCs of 0.42, which qualifies windows for certification under the ENERGY STAR^® 6.0 standard.

Sungate^® 460 glass also features a neutral, clear-glass aesthetic that harmonizes well with brick, stone, wood and metal siding while transmitting high levels of daylight.
