Therma-Tru Door Systems Meet NAFS Requirements
Key Elements of NAFS
The North American Fenestration Standard AAMA/WDMA/CSA 101/I.S.2/A440 (NAFS) is a standard/specification for side-hinged doors, sliding doors, windows, tubular daylighting devices and skylights to be tested against. Based on the door system’s structural performance and resistance to air leakage, water penetration, wind-load and forced entry, a design pressure is determined and a performance grade is given.
Recently, the National Building Code of Canada has been revised and now calls for side-hinged door systems to be tested to this specification. Therma-Tru has already tested many of our door systems to repeatedly meet NAFS specifications, providing a range of products that comply with the new National Building Code of Canada.
