The National Fenestration Rating Council (NFRC) Product Certification Program was developed to create a standardized procedure for rating the performance of windows, doors, and skylights. Prior to the development of the NFRC program, there was no single standardized procedure for rating products which created confusion, resulted in inconsistencies, and made it impossible to directly compare products. Obtaining NFRC product certification results in a rating classification, a program label for customer verification, and entry in the NFRC Certified Product Directory.

As a full-service testing lab and experts on the certification process, we’ve compiled some of the most frequently asked questions and answers about product certification procedures as required by the NFRC.

Q. Who is the Inspection Agency and what is their role?

A. NFRC requires certification by an accredited third-party agency. The Inspection Agency of the manufacturer’s choosing reviews the submitted computer simulations and physical test reports to confirm product compliance. Once compliance is verified, the Inspection Agency issues the certification. In addition, the third-party agency selected will conduct yearly plant audits to ensure on-going compliance.

Q. Do I have to perform the computer simulations and physical testing?

A. Yes, both the computer simulations and physical testing must be completed in order obtain certification. The physical test is conducted in order to validate the results produced by the computer simulation. This process ensures the product is being fabricated as indicated in the drawings.

Q. Do the computer simulations have to be completed before the physical tests?

A. There is no specific order required as long as both the computer simulations and physical testing are completed. If expectations for the product performance are unclear, it is recommended that the simulations are completed first, thus allowing any necessary design modifications to be completed prior to the fabrication of the physical test units.

Q. Will the physical test samples be returned upon completion of testing?

A. Each product must be deconstructed for verification against the drawings to ensure it was fabricated as specified.
