The Challenge
Why This Product Exists
Fire in a building spreads through glass openings in minutes. Standard glass shatters within 2-3 minutes of fire exposure, creating deadly pathways for flames, smoke, and radiant heat. Building codes demand fire-rated barriers, but architects need solutions that don't sacrifice transparency and natural light.

Common Questions
Frequently Asked Questions
E-rated glass provides integrity only — it prevents flames and smoke from passing through. EI-rated glass provides both integrity and insulation — it also blocks radiant heat transfer, keeping the unexposed side below 140°C. EI is required for escape routes and areas where people may be close to the glass.
Yes, fire-rated glass can be integrated into specially designed fire-rated curtain wall framing systems. The glass and frame must be tested together as a complete system to achieve the required fire rating.
The intumescent interlayers between glass plies expand when exposed to heat, forming an opaque insulating barrier. The glass remains in the frame, blocking flames, smoke, and radiant heat for the rated duration.
We manufacture fire-rated glass from 30 minutes to 180 minutes (3 hours) in both E and EI classifications, covering virtually all building code requirements worldwide.
Yes, fire-rated glass is significantly heavier due to multiple glass plies and intumescent interlayers. A 90-minute EI panel can weigh 50-70 kg/m². Frame and hardware specifications must account for this additional weight.
