Insulated Fire Glass (EI) in Crawley: what's included
Insulated fire glass, classified EI, is glazing that maintains integrity and keeps the temperature rise on the non-fire side within set limits for the rated time. It is usually made of several glass panes bonded with interlayers that foam into an insulating barrier when heated, or with a clear gel that absorbs heat.
- Internal and external-grade build-ups
- EI 30, EI 60, EI 90 and EI 120 glass
- Matched glazing systems and seals
- Insulating glass in sealed double-glazed units

What to check before ordering insulated fire glass in Crawley
How it works
When heated, the interlayers turn opaque and expand, forming an insulating shield. After a fire the glass will need replacing.
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.
Optical quality
Modern EI glass is clear in normal use, with high light transmission at lower ratings.

Yes, in normal conditions. It turns opaque only when heated in a fire.

Do you work on occupied buildings in Crawley?
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
