Energy-Efficient Windows with Thermal Master III Low-E Glass

You'll experience a noticeable difference in comfort when you purchase one of Gorell's most energy-efficient glass systems—Thermal Master III®—for your home. This triple-pane system retains interior heat in cold weather and reflects exterior heat in warm weather, resulting in lower home energy costs and a more comfortable home throughout the year.

Thermal Master III includes SolarControl Plus® low-emissivity coating on two glass pane surfaces and krypton gas fill between the panes. This system provides excellent U-values and is one of the best all-climate glass choices available anywhere. Every window and door incorporating Thermal Master III is ENERGY STAR® qualified!


The glass in the windows you purchase has everything to do with the energy cost savings and level of comfort you will experience with your new windows. Clear double-insulating glass is standard on Gorell windows and doors, but you need a Gorell high-performance Low-E glass system for a real difference in energy efficiency.

To see how Gorell products perform with the various glass options, we encourage you to review the "Whole-Window" U-values of our products. These ratings are used by the National Fenestration Ratings Council (NFRC) to qualify windows for the ENERGY STAR® label. The lower the U-value rating, the more your new windows will lower your energy consumption.
