GANA Releases New Marking and Labeling Glass Informational Bulletin

The Glass Association of North America (GANA) has released the thirteenth and latest in a series of Glass Information Bulletins aimed at providing technical information and education to the architectural fenestration industry. The newest bulletin, Marking and Labeling of Architectural Laminated Glass, provides guidance and clarity to the various permanent marks or manufacturers designations currently being applied and/or require for the glazing infill of a fenestration assembly.

"The purpose of this Glass Information Bulletin is to serve as an overview of the marking and labeling practices in use today for architectural laminated glass," explained Pete Anderson of Viracon and chairman of the group responsible for the Bulletin. "With the expanded use of laminated glass in different applications, including safety glazing, bomb blast and hurricane protection, different marking requirements exist and can be confusing because there is not a single entity that dictates the labeling requirements for all these different applications."

Marking and Labeling of Architectural Laminated Glass, as well as other GANA Glass Informational Bulletins, may be downloaded free of charge from GANA's website at
