The Fenestration and Glazing Industry Alliance (FGIA) has released an updated report addressing causes of glass breakage by reducing damage to edges, corners and surfaces. IGMA TR-3401-25, Preventing Glass Breakage During IGU Design, Manufacture, Transport, Installation and Use, an FGIA document, is now available for purchase in the FGIA online store. This document was last updated in 1996 and covers IG design for applied loads, fabrications, storage and transport, installation and usage.
“Glass breakage occurs when the glass stress from an applied load exceeds the glass strength,” says Amy Becker, FGIA Glass Products Specialist, and staff liaison for the FGIA Preventing Glass Breakage Task Group. “Glass strength varies greatly as a result of small scratches or other surface damage which act as stress concentrators.”
