IG Certification

NFRC’s Participating Insulating Glass Certification Program Directory (the “IGC Directory”) lists third party insulating glass (“IG”) certification programs (the “IGC Programs”) that have represented in writing to NFRC that they meet requirements designated by NFRC for the operation of an independent program for the certification of performance attributes of insulated glass products. Those requirements, approved by NFRC in November 2008 and implemented in January, are set forth in the NFRC 706-2009: Requirements for Participating Insulating Glass Certification Programs.

Insulating glass units used in NFRC certified and labeled products must be certified by a third party IG certification program listed in this directory prior to those products obtaining NFRC certification authorization.

The NFRC 706-2009 provides details for Certification Programs interested in being listed in the IGC Directory.

This requirement shall become mandatory for all Product Certification Program participants in July 2010.
