NFRC’s FenStar® Certification Program ensures window, door, and skylight manufacturers comply with the requirements of the EPA ENERGY STAR® Certification Program. In addition to the ongoing verification testing, the FenStar Certification Program will provide manufacturers an evaluation of their installation instructions, air leakage certification information, and product lines’ ENERGY STAR and NFRC certification labels. Once all the information is evaluated, a certificate will be issued stating the product meets the requirements of the FenStar Program and the ENERGY STAR Certification Program.
If you received a notice of selection for testing, please contact staff as soon as possible with an estimated delivery date for the verification test sample or if there are any questions or concerns regarding the verification test. The verification testing is taking the place of the now defunct Independent Verification Program (IVP). There will be no noticeable change in that program for everyone that passes the test.
The National Fenestration Rating Council (NFRC) is the trusted, independent, nonprofit certification body for the energy performance of windows, doors, and skylights.
