Super Peak Performance™ Krypton Enhanced
Low-E Glass Package

This glass package is designed with both a lower solar heat gain coefficient (.33) and an increased Center of Glass R-Value (9). This combination allows for controlled levels of free solar heat gain in the winter while providing the insulation ability of an increased R-Value, keeping the re-radiated heat and warmth from escaping to the outside, thereby reducing your heating costs. In the summer, the solar heat gain coefficient is low enough to minimize the free solar heat entering the home, so that the pull on your air-conditioning is reduced. The superior insulation characteristic of this glass package keeps the outside heat from entering your home, robbing it of precious air conditioning and energy dollars.

This is an ideal glass package for any climate where heating and cooling costs are of high concern.
