TORONTO — The 2017 edition of the North American Fenestration Standard/Specification (NAFS-17) for windows, doors and skylights has been published.
The standard, which received final approval in January, is the result of a multi-year effort by the American Architectural Manufacturers Association (AAMA), CSA Group and the Window & Door Manufacturers Association (WDMA). The updated 2017 standard replaces the 2011 edition of the joint standard.
The 2011 NAFS standard is already referenced in the 2015 editions of the International Building Code and International Residential Code, with the new standard to be included in the 2018 editions of these codes, states a release issued by CSA Group. The new standard is being proposed to replace the 2011 edition in the National Building Code of Canada when it is updated.
The 2017 standard represents steps toward achieving seamless trade across the U.S./Canadian border for fenestration industry manufacturers, states the release, adding a Canadian supplement to the standard has been created by the CSA A440 Technical Committee to address Canada-only items not included within the new NAFS standard.
“The newest version of NAFS includes three more operator types than the previous edition: folding door systems, parallel opening windows and top turn reversible windows. With these products becoming more prevalent in the industry, it is important that the updated document provide guidance on their testing,” said Steve Fronek, vice-president, design engineering for Wausau Window and Wall Systems, in a statement.
Fronek served as the AAMA’s Joint Document Management Group co-chair.
Joe Hayden, principal engineer for Pella Windows and Doors, who served as WDMA’s JDMG co-chair, stated, “The 2017 version of NAFS is the latest product of the ongoing effort to harmonize standards in North America. This effort started over 20 years ago and is evidence of the fenestration industry’s desire to offer our customers a single, unified performance specification across borders.”
