Understanding the Efficiency Ratings of Insulated Windows
Insulated windows consist of two or more panes and other insulating components that reduce the rate of warm and cold air loss.
When selecting insulated windows for your home, look for the ENERGY STAR®/NFRC label.
The ENERGY STAR logo denotes the window has met strict energy-efficient guidelines set forth by the U.S. Department of Energy and the E.P.A.
The National Fenestration Rating Council (NFRC) is an organization that independently rates and labels the energy performance of windows, doors, and skylights. This label will indicate the NFRC test results of the window.
Know Major Industry Terms to Help in Selecting the Best Energy-Efficient Window for Your Home
- U-Factor: Indicates how well the window prevents heat loss from your home. The lower the number, the better the window guards against heat loss.
- Solar Heat Gain Coefficient (SHGC): Indicates how efficient the window is at blocking heat from the sun. The number is between 0-1 and the lower the number, the better it blocks heat.
- Visible Transmittance (VT): Indicates how much light is permitted through the window. The number is between 0-1 and the higher the number, the greater the potential for daylighting.
- Air Leakage: Indicates how well the window prevents outside air from coming into the home. Rates are usually between 0.1-0.3, and the lower the number, the better the window repels outside air.
- Condensation Resistance: Indicates how well a window resists forming condensation. The number generally falls between 1-100 and the higher the number, the better the window resists condensation.
- Low Emissivity (Low-E): A coating on windows that reduces heat loss from inside the home yet allows heat from the sun to enter the home. The levels of Low-E vary for different climates.
Qualify for Tax Credits with Energy-Efficient Window Replacement
The Federal Government continues to offer tax credits to help off-set some of the costs associated with purchasing replacement windows. In short, you can claim 10% of the cost of ENERGY STAR-qualified windows up to $200.
