Since 80% of a window is glass, real heating and cooling savings come from improved glass performance.
* Our combination of UV-filter Low-E Glass, insulating argon gas and the Intercept Warm Edge Spacer System, Creates significant energy efficiency.
* In winter, a warmer glass temperature is maintained, increasing the R-value by an additional 250%
* In summer, a 56% reduction in solor heat gain helps cut air conditioning costs.
