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 PerformanceTM Glass
Our Peak PerformanceTM Glass system is a dual-pane insulating glass system that combines one lite of high performance Low-E Glass and one lite of clear glass for a U-value of 0.30. Enhancing the air space between the two lites with insulating Argon gas allows these windows to meet ENERGY STAR criteria. Consider the Peak Performance Eco Glass system which combines one lite of high-performance triple coat Low-E Glass and one lite of clear glass, for climates where solar control is important.
Choose from a variety of decorative grid patterns, styles and colors. All grids come between the glass for easy maintenance and a clean, modern look.
