Cooler In The Summer

Thanks to its special low-emissivity (low-e) coating, a door made with Energy Shield Xtreme glass allows 65 percent less heat from the sun to enter your home than a window with ordinary glass. That can reduce summer cooling costs by up to 25 percent. Solar Heat Gain Coefficient (SHGC) is a measure of how much solar heat is transmitted through the glass. A lower SHGC means less summer heat.

Warmer In The Winter

Furnace heat lost through your doors is at its peak on winter nights. When your doors are made with Energy Shield Xtreme glass instead of ordinary glass, this heat loss is cut nearly half, meaning lower heating bills.

Comfortable, Abundant Light

Energy Shield Xtreme glass has a proprietary solar control low-e coating that blocks almost 3/4 of the sun’s heat energy while transmitting abundant natural light.

Fade Protection

The solar control, low-e coating of Energy Shield Xtreme glass blocks ultraviolet (UV) energy, which is traditionally associated with fading, 90% more effectively than ordinary glass. However, a more complete measure of fading resistance called “damageweighted transmittance,” shows that Energy Shield Xtreme glass also protects your fabrics, furniture and carpets from fading caused by visible light.

Energy Shield Xtreme, the latest innovation in windows & doors and the next generation of energy-efficient glass, is a new high-performance coating that gives homeowners enhanced solar control, outstanding winter thermal performance, daylight management, and preferred neutral aesthetics – all at an affordable price.

Note: Tdw-ISO represents potential fading damage caused by both UV and visible light. It is considered by the U.S. Department of Energy and the International Standards Organization (ISO) to be a more accurate barometer of fade resistance than UV transmittance alone. All comparisons are center of glass based on an insulating unit containing 3/4” insulating units; two 1/8” (3mm) glass lights and a 1/2” (12mm) air-filled space for the standard clear insulating glass and argon gas-filled space for the Energy Shield Xtreme insulating glass. Actual glass performance may differ due to glass thickness, gas fill and glass to frame ratio.

Solar Heat Gain Coefficient (SHGC) represents the solar heat gain through the glass relative to the incident solar radiation. It is equal to 86% of the shading coefficient. Figures may vary due to manufacturing tolerances.

All tabulated data are based on the National Fenestration Rating Council (NFRC) methodology, using the Lawrence Berkeley National Laboratory’s Window software.
