The 2011 edition of AAMA/WDMA/CSA 101/I.S.2/A440, NAFS “North American Fenestration Standard/Specification for windows, doors, and skylights” (NAFS-11) has received final approval and is now available. This standard is the result of a multi-year effort by the American Architectural Manufacturers Association (AAMA), Canadian Standards Association (CSA) and Window & Door Manufacturers Association (WDMA). The updated 2011 standard replaces the 2008 edition of the joint standard.

The 2011 NAFS standard is already referenced in the 2012 editions of the International Building Code and International Residential Code, and the new standard is being proposed to replace the 2008 edition in the National Building Code of Canada when it is updated.

The standard underwent a thorough restructuring, with separate sections for products, materials and components, as well as new product criteria sections for parallel opening windows and secondary storm products. The standard also expands the mullion and tubular daylighting device (TDD) sections and adds lead content requirements for hardware.

The 2011 standard represents significant steps toward achieving seamless trade across the U.S./Canadian border for fenestration industry manufacturers. A Canadian Supplement to the standard has been created by the CSA A440 Technical Committee to address those few Canada-only items not included within the new NAFS standard.
