NFRC/Energy Star Labels

The National Fenestration Rating Council (NFRC) is a non-profit organization that administers the only uniform, independent rating and labeling system for energy performance of windows, doors, skylights and attachment products.

The NFRC was formed in response to the energy crises of the 1970s. To address concerns about energy consumption, the fenestration industry developed a host of new energy efficient technologies, including low-e coatings, low-conductance spacers, and gas fills.

NFRC develops and administers energy-related rating and certification programs that serve the public by providing fair, accurate, and credible information on fenestration performance.
