Advanced fiber glass Innergy™ thermal reinforcements are designed to slide into a window's frame during the manufacturing process, replacing the traditional foam filled frame. When combined with the already superior performance of replacement windows from Universal Windows Direct of Akron, Innergy™ thermal reinforcements provide greater support and insulating value to the window.
Made using renewable resources, the fiber glass resing used in the pultruison process is made from 20% soy and other renewable resources.
With over 700 times better thermal performance to similar aluminum products on the market, Innergy&trade reinforcements virtually eliminate the thermal bridge in window frames. Reduced thermal bridge means reduced moisture and more comfortable temperatures in your home
