The National Fenestration Rating Council’s (NFRC) FenStar Certification Program has received American National Standards Institute (ANSI) accreditation. FenStar ensures that windows, doors, and skylights meet Energy Star specifications. ANSI’s National Accreditation Board awarded the accreditation after an extensive review process confirmed that FenStar meets the ISO/IEC 17065 standard used for certification bodies around the world.
NFRC is the only certification body that rates the energy efficiency of windows, doors, and skylights. “[The ANSI accreditation] indicates that our ratings are objective, impartial, and strictly follow our written policies and procedures,” said Deb Callahan, CEO of NFRC.
“This benefits not only manufacturers, but also consumers who now will know, without a doubt, that the fenestration product they are buying has been rigorously tested and verified,” Callahan said.
