Innerglass interior storm windows are significantly more effective at insulating your home and lowering your heating and cooling bills than a traditional outside storm window. In fact, the Innerglass window is 5 times tighter than an exterior storm because the outside storm must be ventilated (you know, the weep holes) to get rid of the condensation that has already happened. In contrast, our interior storm is so tight it provides a vapor barrier on the warm side that stops the condensation in the first place.
Innerglass Window Systems pioneered the use of high performance Low-E glass in our interior storm windows. Low-E glass doubles the R value of regular glass making you warmer in the winter and cooler in the summer. It also cuts out 2/3 of the ultra-violet rays damaging your rugs and furniture.
Our custom made windows are the most affordable, convenient, and energy efficient way to upgrade your existing windows. The Innerglass Window will give you the performance of high end replacement windows at less than half the cost!
