The RDH Group started a new blog dedicated to the application of the North American Fenestration Standard (NAFS) in Canada. The blog is intended for Canadian architects, engineers and building officials. NAFS will address issues of interest to manufacturers of windows, doors and skylights in both Canada and the United States.

The NAFS changes how testing and specifications of fenestration performance in Canada are done. NAFS was intended to harmonize Canadian and U.S. performance testing requirements for windows, doors and skylights, but significant differences remain.
