Laboratory testing is the typical way to verify that fenestration products meet specified structural design pressure (DP) criteria. However, engineering analysis can be a viable alternative when standard lab testing will not be sufficient. This article dives deeper into the Fenestration and Glazing Industry Alliance (FGIA)’s consensus-based process for engineering evaluation of structural integrity: AAMA 2502, Comparative Analysis Procedure for Window and Door Products—which is now approved as a reference standard in the International Building Code (IBC).
The latest edition of North American Fenestration Standard/Specification for windows, doors, and skylights (NAFS), is now available. Compiled by the American Architectural Manufacturers Association (AAMA), Canadian Standards Association (CSA), and Window and Door Manufacturers Association (WDMA), the update, 101/I.S.2/A440-17, replaces the 2011 edition of the joint standard.
In the December 2014 issue of The Construction Specifier, Dean Lewis wrote about the North American Fenestration Standard/Specification for Windows, Doors, and Skylights’s (NAFS’) short-form specification. American Architectural Manufacturers Association/Window and Door Manufacturers Association/Canadian Standards Association (AAMA/WDMA/CSA) 101/I.S. 2/A440, serves as the basis for product certification as required by the International Building Code (IBC).
Fenestration products are becoming undeniably more complex as performance expectations diversify and tighten. The same is true of the standards guiding both designers and specifiers of these products.
After multiple years of collaboration, the American Architectural Manufacturers Association (AAMA), CSA Group, and Window & Door Manufacturers Association (WDMA) have released a ‘user guide’ to the 2011 AAMA/WDMA/CSA 101/I.S.2/A440, North American Fenestration Standard/Specification (NAFS).
