Modern architectural designs are requiring the installation of glazing materials that are capable of performing in multi-peril situations. These applications typically require levels of protection well beyond those of basic safety glazing. As such there has been unprecedented advancement in the types, configurations and complexities of glazing materials currently utilized in architectural applications. 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 in the proper labeling of 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 informational bulletin is to provide guidance and hopefully some clarity to the various permanent marks or manufacturers designations currently being applied and/or required for the glazing infill of a fenestration assembly.
