NFRC - National Fenestration Rating Council Collection

Description:
Formed in the energy crisis of the 1970s, The National Fenestration Rating Council (NFRC administers uniform and independent rating and labeling system for the energy performance of windows, doors, skylights, and attachment products. The standards assist architects, builders, code officials, homeowners, governments, utilities, and manufacturers in determining the heat gains and losses in buildings while using fenestration products. The NFRC documents cover the following:

Fenestration product U-factors
Door systems thermal properties
Thermal performance characteristics
Solar heat gain coefficients
Visible transmittance
Product air leakage
