The unintended consequence is that many U.S. manufacturers do not test water penetration resistance beyond the minimum value, and in my experience, U.S. test labs typically stop testing water penetration once the minimum value is achieved. Confused about NAFS and mullion testing? And NAFS testing reveals an uncomfortable fact: the doors we’ve building and buying for many years did not meet the performance levels the Code expected of the windows installed beside them. Table 9 has two levels of Canadian air infiltration/exfiltration for operable products, while the rates for fixed products. Changes to BC Building Code Requirements for Windows, Doors and Skylights .

In Canada, air leakage measured in both directions, into and out from windows, for the logical reason that windows are subject to both positive and negative wind pressures, and windows often perform differently under positive pressure than under negative pressure. NAFS overwhelms Canadian manufacturers, architects, and code officials with new concepts, new terminology, and a new rating system. On top of that NAFS covers products that previously were not subject to testing: unit skylights, tubular daylighting devices, and side hinged doors.

In much of the country, especially in coastal areas, it needs to be significantly greater than 15% of design pressure (20% in the case of AW products).
