Innergy™ rigid thermal reinforcements are advanced fiber glass inserts, designed to slide easily into window frames for greater support and insulation. When combined with the already superior performance of our replacement windows, Innergy™ reinforcements will provide your home with maximum energy-savings.
Innergy™ reinforcements provide up to 700 times better thermal perfomance over traditional aluminum inserts and virtually eliminates the thermal bridge that exists in windows utilizing aluminum inserts. With this decrease in thermal bridge, comes reduced condesation and moisture on your windows and in your home.
The fiber glass utilized in Innergy™ thermal reinforcements utilizes materials that are renewable. The resin that is used in the pultrusion process, is made from 20% soy and other renewable resources.
