ENERGY STAR®

To achieve ENERGY STAR® status, windows must also be National Fenestration Rating Council (NFRC) approved and labeled for U-Factor (the rate of heat loss through the window) and Solar Heat Gain (how well the window blocks heat from the sun). In warmer climates, solar heat gain can warm air-conditioned indoor space causing excessive energy consumption.

In 2014, the ENERGY STAR® Northern Zone will require a 0.27 U-factor or less, but you don’t have to settle for less today. Contact us to find out where you can find qualifying windows and doors built with Quanex’s high-performance technologies.
