The National Fenestration Rating Council has published and implemented the following NFRC documents:
- ANSI/NFRC 100-20206[E0A0]: Procedure for Determining Fenestration Product U-factor
- ANSI/NFRC 200-2025[E0A0]: Procedure for Determining Fenestration Product Solar Heat Gain Coefficient and Visible Transmittance at Normal Incidence
- ANSI/NFRC 202-2026[0A0]: Procedure for Determining Translucent Fenestration Product Visible Transmittance at Normal Incidence
- ANSI/NFRC 203-2026[E0A0]: Procedure for Determining Visible Transmittance of Tubular Daylighting Devices
- ANSI/NFRC 400-2026[E0A0]: Procedure for Determining Fenestration Product Air Leakage
- ANSI/NFRC 500-2026[E0A0]: Procedure for Determining Fenestration Product Condensation Index Ratings
The changes in these documents are the result of NFRC membership balloting, and approval from the Board of Directors and the Standards Committee. Each document was also open to public comment period as part of the ANSI standards development process. Links to the documents and the REDLINE versions (which show changes made from the previous version) are provided on the Technical Documents page of the NFRC website.
