MEASURING ENERGY PERFORMANCE IN YOUR Middle Tennessee, Southern Kentucky & Northern Alabama WINDOWS.

How can you tell if a window is energy-efficient? National standards have been established for rating the energy performance of replacement windows. These standards are tested and measure by the National Fenestration Rating Council (NFRC) is an independent, non-profit organization that administers the only nationally accepted rating system for energy performance of windows, doors and skylights. The NFRC provides fair, accurate and reliable energy performance ratings so that architects, engineers, builders, code officials, contractors and homeowners can compare different products and make informed choices.

The most important measure of a window’s performance is its U-value. The U-value indicates the rate of heat flow through a window. The lower the U-value, the more energy efficient the window will be. U-value measures the entire window unit — glass, frame, sash, spacers — and is the only measurement accepted by the U.S. Department of Energy’s EnergyStar program.

R-value is the measure of the resistance of glass to the flow of heat. The higher the R-value, the better the glass will be at insulating your home. But R-value is NOT an accepted form of measurement by the National Fenestration Research Council (NFRC) or EnergyStar, as it does not measure the overall window unit.

Look for the NFRC label on any replacement window Middle Tennessee, Southern Kentucky & Northern Alabama you purchase.


The glass packages available in replacement windows installed by Integrity Roofing TN LLC include some of the most advanced features available today. The heart of our replacement windows is a technologically advanced glass called “Low-E “glass.

Low-E Glass maximizes your home’s energy efficiency by reducing the amount of heat entering or escaping. Low-E (“low emissivity”) Glass has a thin layer of oxidized metal on one side, which greatly enhances the glass insulating properties. Heat and light are allowed to enter, but the thin metal sheen does not allow heat or light back out. The glass is still transparent, yet is incredibly efficient at reducing energy loss.
