Why is NFRC so important?

The NFRC Label will not tell you which window to purchase, but NFRC Certified Ratings can be a valuable tool, much like that miles-per-gallon sticker on a new car. 

The NFRC Label provides the following: 

Whole Product Ratings-The NFRC testing protocols involve testing of the full window, including glass, frame, spacers and any other component that is a permanent part of the complete product. This strategy provides you with a more accurate reflection of how the product will perform in the home than testing of just glass, as the framing and other components influence ratings such as U-factor, Solar Heat Gain, and Visible Transmittance. 

Information You Can Trust-The NFRC Label is the only window label that provides Certified Ratings that are acquired through independent testing of the product. 

The NFRC rating process provides you with a way to verify that the Certified Ratings provided on the NFRC Label are accurate via the Certified Products Directory (CPD). The NFRC Label provides the manufacturer name, the type of window, as well as the Full CPD Number, making searching the database for the product a snap. 

Ratings on the NFRC Label have been achieved through standardized test methods at independently operated laboratories. This standardized method allows you to compare Certified Ratings on the NFRC Label of Manufacturer “A” to those on the Certified Label of Manufacturer “B” – for equal and fair comparisons.
