Subsection 9.7.4. of the 2012 BC Building Code requires windows, doors and skylights to conform to AAMA/WDMA/CSA 101/I.S.2/A440-08 NAFS – North American Fenestration Standard/Specification for Windows, Doors, and Skylights (NAFS). This newly referenced standard may require manufacturers to test a broader range of products. As a result, there may be a temporary shortage of NAFS conforming products available in BC.
The attached regulation permits windows, doors and skylights to conform to either the 2006 BC Building Code, or NAFS until July 1, 2013. Any window, door and skylight installed on or after July 2, 2013 must conform to the new NAFS Standard as well as A440S1-09 Canadian Supplement to AAMA/WDMA/CSA 101/I.S.2/A440, NAFS – North American Fenestration Standard/Specification for Windows, Doors, and Skylights.
This temporary delay will allow industry some time to have products tested and manufactured to the new NAFS standard.
