Our buildings alone consume 40% of our nation’s energy. The energy lost through inefficient windows, by some estimates, represents 30% or more of building heating and cooling energy. While it may be generally accepted that dual pane windows (invented in 1865) are energy efficient – they aren’t. We can solve this problem today with super-insulating windows that can reduce heating and cooling costs significantly.
What’s the R-value?
A measure of window insulation is R-value. The higher the R-value, the better. A single pane window has an R-value of R-1; dual pane is R-2.

Super-insulating windows of high R-values of R-5.0 or higher can help you save the highest percentage of heating and cooling costs when compared to other windows available today (depending on location, building type, and other factors) - delivering comfort and savings benefits, year after year.
