Earlier this year, the Fenestration and Glazing Industry Alliance (FGIA) updated the 2017 edition and published the 2022 edition of the North American Fenestration Standard/Specifications (NAFS) for windows, doors, secondary storm products (SSPs), tubular daylight devices (TDDs), roof windows, and unit skylights.
The 2017 NAFS is part of the 2020 edition of the National Building Code of Canada (NBC), while the 2011 NAFS is part of the 2012 edition (with current amendments) of the Ontario Building Code (OBC). Current designs, as a minimum, must meet the version of the standards referenced in the applicable building codes, but meeting the new standards may be a way of future-proofing a design, with potential for marketing advantages to clients.
Anticipating continued harmonization of the OBC and NBC, members may consider becoming more familiar with the following CSA documents:
- CSA A440.2:22/CSA A440.3:22 – Fenestration Energy Performance (and User Guide);
- AAMA/WDMA/CSA 101/I.S.2/A440:22 – NAFS for Windows, Doors, and Skylights; and
- CSA A440.4:19 - Window, Door, and Skylight Installation.
These documents can be accessed for free by OAA licensed members who register for the OAA’s CSA Standards Access Program, which offers viewing access to all CSA documents referenced in the National Building Code and the Ontario Building Code.
