FIREGLASS is a fire-rated and safety-rated glass that blocks radiant heat to protect people and valuables on the non-fire side. It has a fire rating of up to two hours and acts as a barrier to flame and heat and smoke. The impact safety rating meets ANSI Z97.1 and CPSC 16CFR1201 standards. These panels can offer additional bullet resistance up to UL Level III. It’s important to note that fire-resistant windows do not function in isolation – they only work as part of a system involving the glass, the framing and anchoring, and the building’s structure. The glass panel will likely fail if the framing or anchoring system is not fire-resistant. We will provide you with a qualified engineer to help you create the ideal design for your fire-resistant project.
