The National Fenestration Rating Council (NFRC) wants your feedback.

Its ANS Standards Committee and NFRC Board of Directors approved a plan to submit changes to the ANSI/NFRC 100: Procedure for Determining Fenestration Product U-factors for public review. These changes, which were balloted and approved by NFRC membership at the spring 2015 committee week meeting, have not yet been implemented and are pending completion of the public review.

The changes are open to the public for 30 days, closing on October 18, 2015.

The next public review of the ANSI/NFRC documents will take place in January 2017 and will include any changes approved by NFRC membership between now and then.
