Verifying fenestration’s structural strength when lab testing does not apply
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).
