Why Window Performance Ratings Are Important

The NFRC (National Fenestration Ratings Council) provides ratings for every type of window and it’s these ratings that determine whether or not a particular window meets ENERGY STAR® qualifications.

The Lower the Rating The More Energy You Save!

The lower the rating, the lower your home’s energy consumption will likely be, meaning your heating and cooling bills will be lower, too!

This means that installing ENERGY STAR® certified windows will help you stay more comfortable in your home, while saving money AND the environment.

All of Our Windows Are ENERGY STAR® certified

Al of the windows that we carry meet the stringent 2016 ENERGY STAR Performance Requirements for the U.S. climate zone.
