How To Understand The Ratings On Energy Efficient Windows

While you might hear a lot of claims about windows and energy-efficiency, you don’t have to guess about which claims are true. Instead, you can turn to objective, unbiased ratings that tell you how efficient a replacement window really is.

Windows come with an NFRC sticker. These ratings are important and unbiased, and the NFRC label is the only one accepted by the US Department of Energy’s Energy Star program.

So, what ratings should you look at and what do they mean?

One of the first ratings you should see is the U-Factor, and the lower it is the better. U-Factor tells you how fast you lose heat out your windows in the winter. Obviously, the higher the rate of heat loss, the higher your energy bill will be in the winter.

For Colorado Springs and the winters we typically get, always look for a 0.30 rating or less. If more energy-efficiency is an important factor for you, invest a little more and get something 0.25 or less.

Other Energy Efficient Window Ratings:

Solar Heat Gain Coefficient (SHGC): This rating is about how well a window will perform in the summer – it tells you how much solar radiation a window will allow to penetrate. The rating is on a scale between 0 and 1, and once again, lower means better. A good SHGC for our climate is 0.32 or less.

Air Leakage: This measures the amount of air that can pass through a window. Once again, the lower the better. 0.1 is the very best – that’s the lowest possible score that can be measured. For reference, consider 0.2 good; 0.3 average; and 0.4 or higher as unacceptable.
