Energy Conservation

ClimaTech your solution for increased window performance

Our optional ClimaTech insulated glass package combines multi-layered low-emissivity (Low-E) glass, argon gas and the PPG Intercept Warm-Edge Spacer System. ClimaTech is up to 40% more energy efficient than most other Low-E or Mid-E glass systems and provides more than twice the energy efficiency of clear glass units.

Low-E glass filters, long wave radiation from the sun. This reduces solar heat gain from the summer sun, helping to keep your home cooler.

Low-E glass takes on a new duty in winter months.; It lets warm solar rays into your home while preventing indoor heat from escaping.

UltraMaxx Windows with ClimaTech exceed the performance requirements set forth by the U.S. Department of Energy in conjunction with the National Fenestration Rating Council (NFRC) test criteria.

One of the most critical NFRC tests measures the rate of heat loss through a window or door (U-factor). The lower the U-factor, the better the product is at resisting heat flow, which results in a product with a greater insulating value.

Performance Options - Make your home an energy miser. It's Easy!

What makes the ClimaTech insulated glass package so effective? Since 80% of a window is glass, substantial heating and cooling savings come from improved glass performance.

The superior thermal performance of this insulating glass unit can help lower your energy costs while further reducing the consumption of fossil fuels.

*Our combination of UV-filtering Low-E glass, argon gas and the Intercept Warm-Edge Spacer System dramatically enhances energy efficiency. Together they can cut the damaging effects of the sun, which can lead to the fading of carpets, curtains and furniture, by an additional 72% over clear insulated glass units.
* In winter, a warmer glass temperature is maintained, increasing the R-Value by up to an additional 104%
* In summer, up to a 49% reduction in solar heat gain helps cut air-conditioning costs.
