Fenestration Standard is Approved by CSA

The newest fenestration standard, AAMA/WDMA/CSA 101/1.S. 2/A440-04, Standard/Specification for Windows, Doors, and Unit Skylights, has been approved by the Canadian Standards Association (CSA), and on January 7, 2005, was officially approved by a joint meeting of executives of the three associations involved, according to the American Architectural Manufacturers Association (AAMA). The format, which is expected to become effective in 2006, was published by the AAMA, the Window & Door Manufacturers Association (WDMA) and the Canadian Window and Door Manufacturers Association (CWDMA). The new document now covers the category of side-hinged doors.

"101/1.S. 2/A440-04 represents years of collaboration within our industry; yet a few hurdles remain before it will be fully implemented. We expect initial acceptance into the IBC and IRC very soon, with the final ICC hearing for code adoption set for September," said Dean Lewis, certification manager for AAMA. "Realistically, however, it may be another three years before all manufacturers will be certifying their products to the most current uniform North American standard."

Lewis explained that the test standards used in the 1997 document are not identical to the same test standards in the 2002 document. The later standards were converted to metric equivalents, and minimum performance requirements were rounded up to the nearest number. Until products certified under 1997 standards are re-certified under 101/1.S. 2/A440-04, they are not in compliance with the most recent harmonized standard, according to AAMA. AAMA recommends a transition period in which the 1997 and 2002 documents are accepted along with the newest document.

"There's simply not enough capacity at accredited testing laboratories to re-certify products currently listed under the 1997 label. However, after this relatively short transition period, acceptance of a uniform performance standard for the United States and Canada will facilitate the manufacturing and marketing of window and door products across the border," said Lewis.
