insulating glass Viracon with a Triple
Triple insulating glass sizes up to 70 square feet are now available from Viracon. A dual-pane product consisting of a ¼-inch (6-mm) exterior lite with a VRE-54 coating on the number-two surface, ½-inch (13.2-mm) air space and a ¼-inch (6-mm) interior lite yields a winter U-value of 0.30 and a solar heat gain coefficient (SHGC) of 0.31, according to the company. Using the same components, but adding another ½-inch (13.2-mm) air spacer with a third ¼-inch (6-mm) new interior lite yields a winter U-value of 0.22 and a SHGC of 0.28.
Applying a second high-performance coating, such as VE-85, on the number-four surface (second lite) of the same triple insulating glass construction improves the winter U-value to 0.16 and the SHGC to 0.25, according to the company. www.viracon.com

thermal barriers Questions and Answers
Through its AZO/Tec® technical services department, Azon says it partners with aluminum extruders and window manufacturers, working to improve the energy-saving properties of thermal barrier materials. The company offers assistance to fenestration designers and manufacturers in optimizing product designs, starting with questions about end-use, size and structural requirements of the door, window, curtainwall or skylight assembly.
According to the company, by adding a second thermal barrier cavity in a profile or utilizing the wider MLP™ cavity design, the U-factor may be lowered as much as 25 percent—which can be significant in meeting stringent energy codes. www.azonintl.com
