What does AAMA and NRFC certified mean to homeowners?
The American Architectural Manufacturers Association (AAMA) sets all performance standards, product certification and educational programs for the window industry. When a product passes AAMA tests, it guarantees reliable performance if properly installed. The National Fenestration Rating Council (NFRC) is a non-profit organization created by the Department of Energy and the window and door industry. The NFRC provides consistent ratings on windows and doors relating to the energy performance of that product. The NFRC label on a window or door informs consumers about a product’s U-factor, which takes into account a product’s ability to block warming caused by sunlight, light transmittance and air leakage through cracks in the product’s assembly.
