2022 North American Fenestration Standard Published
The 2022 edition of AAMA/WDMA/CSA 101/I.S.2/A440, “North American Fenestration Standard/Specification for windows, doors and skylights,” has been published. This standard is the result of a multi-year effort by CSA Group, Fenestration and Glazing Industry Alliance and Window & Door Manufacturers Association. The updated 2022 standard replaces the 2017 edition, representing a continued evolution of the standard to improve harmonization across North America.
The 2017 NAFS standard is already referenced in the 2021 editions of the International Building Code and International Residential Code, with the recently released standard proposed to be included in the 2024 editions of these codes. The 2017 NAFS standard is also referenced in the 2020 edition of the National Building Code of Canada, with the recently released standard proposed to be included in the 2025 edition.
