To provide guidance and clarity to the various permanent marks or manufacturer’s designations

Product Details

Because of the tremendous increase in the recognized performance of glass and other glazing, the concern over properly identified components of a fenestration assembly has also increased. Currently, there are several industry guidelines that assist the frame manufacturer to properly label framing systems, but very little guidance is available for the glazing that is placed inside the frame, referenced as the “infill”. The purpose of this technical paper is to provide guidance and clarity to the various permanent marks or manufacturer’s designations currently being applied and/or required for the laminated glass infill of a fenestration assembly.

The Technical Services Division of the National Glass Association (NGA) has produced this Glass Technical Paper solely for informational purposes. This Paper was developed by dedicated member volunteers and subject matter experts. The original version of this document was approved and published in 2006. This version of the paper was updated and published in September 2022. All purchases will be electronically accessed or delivered.
