Facts about Energy Efficient Windows Ratings

Energy efficient windows help save money, and protect your investment. The U Factor of a window measures the rate of heat transfer and implies how good the window is insulated. The lower the U-Factor energy rating, the more energy efficient  the replacement window becomes. The NFRC label  provides window and door retailers with fact sheets that can be used to educate their customers at the point of purchase.  We utilize this tool help our customers purchase the best products on the market today to help provide information on energy efficient windows.

Here are some facts stated from the NFRC:

1. The fact sheets explain how to interpret the values found on the NFRC energy performance rating label, which is displayed on many products. You can also use the ENERGY STAR  Store Locator  to locate a store that provides windows and window products with the NFRC label.

2. U-factor measures how well a product prevents heat from escaping a home or building. U-factor ratings generally fall between 0.15 and 1.20. The lower the U-factor, the better a product is at keeping heat inside the building. U-factor is particularly important during the winter heating season in colder climates. This label displays U-factor in U.S. units. Labels on products sold in markets outside the U.S. may display U-factor in metric units.

Under the NFRC program, windows, doors, and skylights – otherwise known as fenestration products – are independently tested, certified, and labeled. Our label does not recommend which products to buy. It simply provides homeowners with information on how the product will perform so you can decide for yourself if it’s right for you?
