The 2022 edition of AAMA/WDMA/CSA 101/I.S.2/A440, “North American Fenestration Standard/Specification for windows, doors, and skylights” (NAFS) has been published.
The updated 2022 standard replaces the 2017 edition, part of a continued evolution of the standard to improve harmonization across North America, according to a news release. The 2017 NAFS standard is already referenced in the 2021 editions of the International Building Code and International Residential Code, and the recently released standard is 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. The new standard harmonizes some differences between U.S. and Canadian provisions in earlier editions.
The new edition includes an important change regarding evaluation of mulled products. The latest edition includes provisions for evaluating mullions for composite window products.
