Fire Rated Glass Buyer Guide

E, EW, and EI are the three most common fire resistance classifications used for fire rated glass in international construction projects. Each classification represents a different level of protection against flames, heat radiation, and temperature transfer during a fire event.

Yes, many suppliers offer custom sizes, but the maximum size depends on the product structure, fire rating, and tested system limitations. For buyers, size customization is not just about fabrication capability. It is about whether the requested dimensions are still valid within the approved fire-rated glazing system.

Buyers should review valid third-party fire test reports, product certifications, and the approved application scope for the intended project. In international fire rated glazing procurement, documentation is not a formality. It is one of the main factors that determines compliance, approval, and purchasing confidence.

Yes, fire rated glass can be used in curtain wall systems, but only when the glass is compatible with the curtain wall framing system and, in many cases, when the full tested glazing system has been approved for that application.
