How do you know the windows in your home are energy efficient? They have to be labeled as such by NFRC, and they must meet Energy Star standards for efficiency. You can also look at the U-Factor and Solar Heat Gain Coefficient (SHGC) ratings of potential new windows!

You can also look at the U-Factor and Solar Heat Gain Coefficient (SHGC) ratings of your potential new windows in order to get an idea of their overall energy efficiency. Both of these numbers are listed on the NFRC label as well as online through third party websites like RaterCalc.com or WindowEnergyRating.org . These sites allow you to compare different brands and models side by side so that you can find which one is right for your needs!

The amount of air infiltration that occurs in a window can vary greatly depending on the design and construction. It’s important to understand what kind of performance rating each window has so you can make an informed decision when choosing new windows for your home.

Air leakage is a major problem in the United States. In fact, it’s estimated that around 30% of energy loss in buildings comes from air infiltration. This means that if you have an older home with single pane windows, you could be losing up to 50% of your heating and cooling costs through those windows alone!

Air leakage is one of the most important factors to consider when purchasing replacement windows because it will have a direct impact on your energy bills, comfort level, and even indoor air quality. If you are looking for ways to save money on heating and cooling costs this summer, then reducing air infiltration should be at the top of your list!
