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 706-2010 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.

Notice to Consumers and Other Interested Stakeholders Regarding IG Certification

NFRC recently implemented a new requirement (NFRC 706) under its Product Certification Program requiring insulating glass units (IGUs) used in NFRC certified and labeled products to be certified as meeting certain performance requirements by an independent IG certification program (“IGC Program(s)”) listed by NFRC. This requirement went into effect on July 1, 2010.

Some NFRC participants have requested extensions of time to comply with specific NFRC program requirements for reasons identified by those participants. Under strict guidance following NFRC policy, some requests have been granted allowing those program participants to extend the period of time to comply with the IG certification requirement under NFRC 706. Those extensions expire no later than July 1, 2011. Therefore, currently there are products listed in the NFRC Certified Products Directory that have been granted compliance extensions that have not yet received the independent IG certification mandated under NFRC 706.

If you have a question as to whether an NFRC certified and labeled product currently complies with this IG certification requirement, please contact the manufacturer of that product.
