Energy Efficient Glass Options

Thermal Windows & Doors is proud to manufacture vinyl replacement windows and doors with the ENERGY STAR® label. Every ENERGY STAR qualified window is independently certified by the National Fenestration Ratings Council, or NFRC, to perform at or above strict levels set by the U.S. Department of Energy. The rating gives you the tools needed to compare window performance.

Peak Performance Glass

Our Peak Performance Eco Glass system is a dual-pane insulating glass system that combines one lite of high performance triple coat Low-E Glass and one lite of clear glass. The air space between the two is enhanced with Argon, an insulating gas.
