Harmonizing North American fenestration standard

The 2011 North American Fenestration Standard/Specification (NAFS) has received final approval as AAMA/WDMA/CSA 101/I.S.2/A440. The new document is part of efforts to harmonize North American standards. It is already referenced in the 2012 editions of the International Building Code (IBC) and is being proposed to be incorporated into the forthcoming update of National Building Code of Canada (NBC). The new standard addresses products, materials, and components separately, along with new product criteria sections for parallel opening windows and secondary storm products. The Canadian Standards Association’s (CSA’s) A440 Technical Committee has created a Canadian supplement for Canada-only items not included within the new NAFS standard.
