Air Infiltration

When it comes to air infiltration, less is more. The lower the CFM (cubic feet per minute), the less air the window lets pass through. This example shows how our windows compare to other windows and industry standards.

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 Performance 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. The air space between the two is enhanced with Argon, an insulating gas. Consider the Peak Performance 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.

Peak PerformanceTM Ultra Glass

Peak Performance Ultra Glass combines triple glazing, Low-E Glass and Argon gas to offer a U-factor of 0.24, an insulating value that exceeds ENERGY STAR criteria.

Peak PerformanceTM Elite Glass

The addition of Krypton gas for optimal insulation gives our Peak Performance Elite Glass system an exceptional U-factor of 0.20, which far exceeds ENERGY STAR criteria and Department of Energy R-5 criteria (the lower the U-factor, the better a window insulates).
