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).

Rooftop skylight replacement considerations

Design professionals tasked with replacing rooftop skylights on commercial or institutional buildings have the opportunity to enhance the building appearance, upgrade energy conservation performance, and improve building occupant experience while remedying water penetration, air infiltration, and condensation problems common with older systems. Achieving these objectives is viable, but the replacement design process is multifaceted.
