Insulated Fire Glass (EI) in Southend-on-Sea: what's included
EI glass is the choice where people need to pass close to the glass during a fire, where combustible materials sit near it, or where building guidance would otherwise restrict glazing. We supply and fit EI 30 to EI 120 glass in tested frames, internally and externally.
- EI 30, EI 60, EI 90 and EI 120 glass
- Insulating glass in sealed double-glazed units
- Impact-classified insulating glass
- Matched glazing systems and seals
Before you order insulated fire glass: what matters
The temperature rule
EI testing limits the average temperature rise on the unexposed face to 140°C and any single point to 180°C, which is why people can pass it.
Thickness and weight
Each step up in rating adds layers, so EI 120 is far thicker and heavier than EI 30. The frame has to be designed for it.
How it works
When heated, the interlayers turn opaque and expand, forming an insulating shield. After a fire the glass will need replacing.
