Understanding the NFRC Ratings Label

Questions About Window Energy Performance? NFRC Has the Answers

The National Fenestration Rating Council (NFRC) rates the energy performance of windows, doors, and skylights. These ratings can be a valuable tool, much like the miles-per-gallon sticker on a new car, because they can help you to:

  • Compare different products on an apples-to-apples basis
  • Verify that a product will perform as the manufacturer claims
  • Make an informed choice about an expensive product that will stay in your home for many years

The color, frame, price, warranty, and a dozen other things are up to you. But when it comes to energy performance, NFRC can be a powerful partner as you search for the perfect window for your home.

A Source You Can Trust

NFRC ratings are fair, accurate, and credible because the rating system is independent – manufacturers have no say over how their products are rated. That’s why the federal government and energy codes in many states and local jurisdictions encourage homeowners to purchase only NFRC-rated products.

Understanding the NFRC Label

Only NFRC labels – with the NFRC logo – provide credible ratings for a number of energy performance characteristics.
