The NFRC Label

Below you will see an infographic that includes an example of what an NFRC label looks like. This label should remain on your window until after the final inspection. You should keep these labels for your records.

The U-factor, Solar Heat Gain Coefficient (SHGC) and Visible Transmittance (VT) are all tests that are required by ENERGY STAR®. Air Leakage and Condensation Resistance ratings are optional and manufacturers are not required by NFRC to test their products for these.
