What is the NFRC?
The National Fenestration Rating Council (NFRC) is a nonprofit, public/private organization created by the window, door, and skylight industry. It comprises manufacturers, suppliers, code officials, researchers, and government agencies. The NFRC has developed a fenestration energy rating system based on certified whole product performance.
All major standards and programs for window energy efficiency — including building energy codes, tax credits, utility incentives, ENERGY STAR, and others — base their criteria on certified National Fenestration Rating Council (NFRC) ratings. To ensure that their products are recognized, manufacturers must participate in the NFRC certification and labeling program.
Independent energy ratings. Informed purchase decisions.
NFRC-certified products are independently tested, certified, and labeled to help you make the best purchase decision for your needs. While the ENERGY STAR label tells you if a product is energy-efficient, the NFRC label allows you compare between energy-efficient products by breaking down a product’s energy performance.
What does the NFRC label tell you?
The NFRC label helps you compare between energy-efficient windows, doors, and skylights by providing you with energy performance ratings in multiple categories.
The NFRC also has a condensation rating that manufacturers can include. You may or may not see it on the label. The higher the number, the better a product resists condensation. Download the optional label.
