A new 2022 edition of AAMA\/WDMA\/CSA 101\/I.S.2\/A440, \u201cNorth American Fenestration Standard\/Specification for windows, doors, and skylights\u201d (NAFS) has been published, and it includes some changes for Canada.<\/p>\n

The result of a multi-year effort by CSA Group, Fenestration and Glazing Industry Alliance (FGIA) and Window & Door Manufacturers Association (WDMA), the new updated 2022 standard replaces the 2017 edition, representing what the groups call a \u201ccontinued evolution of the standard to improve harmonization across North America.\u201d<\/p>\n

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.<\/p>\n

Operating Force
<\/em><\/strong>\u201cOperating force tables were combined to include all product types and Performance Classes, and a single requirement identifies the maximum \u2018force to initiate\u2019 and \u2018force in motion.\u2019 This was done to both simplify and to harmonize requirements between Canada and the United States,\u201d said Brad Fevold, director of regulatory affairs for Marvin, who served as WDMA\u2019s JDMG co-chair.<\/p>\n

Door Requirements
<\/em><\/strong>\u201c\u2018Another change is that the Limited Water (LW) rating and designations for sliding doors were added to provide consistency for all door products. Finally, folding door assembly qualifications were revised and updated to include an additional sixth configuration to better reflect the breadth of product offerings in the market,\u201d said Fevold.<\/p>\n

Material and Components
<\/em><\/strong>\u201c\u2018Material and Components\u2019 clauses were partitioned into \u2018Requirements without Alternative,\u2019 \u2018Requirements with Alternative\u2019 and \u2018Design Guidance.\u2019 In addition, prescriptive or redundant auxiliary and component tests were removed,\u201d said Steve Fronek, P.E. and vice president, preconstruction for Wausau Window and Wall Systems, who served as FGIA\u2019s JDMG co-chair.<\/p>\n

Concise Clauses
<\/em><\/strong>To maximize continuous improvement opportunities, every clause in NAFS-22 was subjected to review and enhancement using time-tested, inclusive, consensus-based processes at each of the JDMG associations. \u201cThe result is a concise, quality-focused standard, allowing for end-product performance evaluation, as well as meeting secondary goals including product comparison, durability assessment and addressing technical certification issues,\u201d said Fronek.<\/p>\n

Canada\/U.S. Harmonization
<\/em><\/strong>Several Canadian-specific changes are reflected in NAFS-22. \u201cNAFS-22 is a huge achievement for its impact on products intended for the Canadian market, as it has been harmonized to address both countries\u2019 requirements,\u201d said Robert Jutras, chair of CSA\u2019s technical committee and CSA\u2019s JDMG co-chair. In Canada, the selection of the water penetration resistance test pressure is still defined in accordance with the A440S1 Canadian Supplement to NAFS, and air exfiltration testing will now be required in the U.S.,\u201d he added.<\/p>\n

Mulled Products
<\/em><\/strong>Additionally, Jutras pointed out an important change regarding evaluation of mulled products. This change was the transition from AAMA 450-10 to AAMA 450-20, which now includes provisions for evaluating mullions for composite window products. Finally, Jutras noted that the tables for the Available Performance Grade Requirements have been consolidated. \u201cThis was done to provide clarity for specifiers,\u201d Jutras said.<\/p>\n
