When traditional wired glass was the only glazing material offering fire protection, building codes limited fire-rated glass to 100 square inch vision lites in doors with stringent fire-rated criteria. As new fire-rated glass products entered the market with improved performance and impact safety protection, this restriction was removed.
Now, according to the International Building Code (IBC), glazing is permitted in fire-rated doors assuming it has passed the relative testing requirements (2021 IBC section 716.2.5.1). Glass size limitations are up to each door manufacturer (as tested/listed by independent testing agency). In addition, each door manufacturer will have their own stile and rail requirements.
Where the architect or building owner desires a full-lite, fire-rated glass door to maximize natural light or improve wayfinding, fire-protective glass doors with a 20- or 45-minute rating can often be used in the maximum size (as tested/listed by an independent testing agency). In doors with temperature-rise criteria, fire-resistive glass is an alternative. Since it is tested to ASTM E119, the standard for fire walls, it is suitable for use in all doors, without any size limitations beyond what has been tested and certified/listed by the manufacturer.
To meet a variety of design goals and fire- and life-safety needs, Golden House(GH) offers fire-rated glass products approved for full-lite doors for 20-, 45-, 60- and 90-minute applications.
