Question 8

What is the NFRC rating?

Accepted Answer

The NFRC (National Fenestration Rating Council) is an independent, non-profit American organization that establishes objective energy performance ratings for windows, doors, and skylights. NFRC-rated products are independently tested, certified, and labeled. While ENERGY STAR certification tells you if a product is energy-efficient, NFRC certification helps you compare energy-efficient products by breaking down a product's energy performance.
