The National Fenestration Rating Council (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.
Unfortunately, in advertising these new technologies some manufacturers made outlandish claims about the performance of their products. Consumers complained, and the federal government began to investigate.
By the late 1980s, industry stakeholders staved off confusion, federal intervention, and perhaps costly litigation by coming together in 1989 and founding NFRC to provide independent verification of product performance.
