The state of affairs in the glazing market has changed quite a bit in the past few years,” says Brian Hedlund, product marketing manager for windows at Klamath Falls, Ore.–based Jeld-Wen. “Green [building] is tremendously important, and energy efficiency is a big deal.” The average energy-efficient window uses a standard glazing package that includes low-E insulated glass, and it is more energy efficient than windows from 15 or even ﬁve years ago. But in conjunction with their glass-producing partners, window manufacturers are now able to offer glazing that increases energy efficiency or addresses speciﬁc situations. LOCATION, LOCATION TRIPLE PROTECTION: Designer Series triplepane windows are the manufacturer’s most energy efficient. The triple-glazed windows offer energy efficiency and noise reduction. Betweenthe-glass blinds reduce heat gain by 43 percent and minimize airborne allergens. ▪ Pella Window & Door. 888-847-3552. www.pella.com. Circle no. 111. Home buyers in different regions, for example, have different needs. In the North, a window’s U-factor, which measures how well a window prevents heat from escaping, is important. Buyers in warmer states, on the other hand, should be concerned with the solar heat gain coefficient, which mea- LABEL GAZING sures how well a window blocks heat from An easy way to see if a window meets your the sun.
