Energy performance ratings can help you determine if your replacement window is the right choice for your needs and budget. The National Fenestration Rating Council (NFRC) operates a voluntary program that tests, certifies, and labels windows based on their energy performance. Here’s what the label means to help you make your home energy-efficient:
Understanding Energy Performance Ratings
Chances are, when you go for energy-efficient windows, you’ll see an NFRC label. This is because ENERGY STAR® requires this label for their certification as well. You’ll usually see three ratings on the label: U-Factor, Solar Heat Gain Coefficient, and Visible Transmittance.
As an expert windows company in Waterloo, IA, we can explain all these ratings. The U-factor typically ranges from 0.20-1.20. The lower the U-factor, the less heat escapes from your windows. The U-factor rating is important for homes that experience cold winters or excessive heating bills.
The Solar Heat Gain Coefficient or SHGC is kind the opposite. It’s a number between zero to one that measures the amount of outside heat that can enter your windows. Lower numbers are better. As an experienced Waterloo, IA, windows contractor, we suggest going for a good SHGC rating if your home experiences hot summers.
Finally, there’s the Visible Transmittance rating. This rating measures the amount of visible sunlight that can enter your room. In this case, a higher number is better.
