What's involved with insulated fire glass in Horsham
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.
- Matched glazing systems and seals
- Handling and installation of heavy panes
- Internal and external-grade build-ups
- Insulating glass in sealed double-glazed units
How we work in Horsham
England rules applied
Designs follow the building and fire safety rules that apply in England, not a one-size-fits-all approach.
Rated systems, not just rated glass
Every quote in Horsham identifies the tested system: frame, glass, beads, seals and fixings, within its pane-size limits.
Fixed written quotes
After survey you get a fixed written quote for the agreed scope, so Horsham budgets are not open-ended.
Before you order insulated fire glass: what matters
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.
How it works
When heated, the interlayers turn opaque and expand, forming an insulating shield. After a fire the glass will need replacing.

What does EI 60 mean?
The glazing system kept fire on one side (integrity) and limited the temperature rise on the other side (insulation) for at least 60 minutes in a standard fire test.
Why is insulated fire glass so much more expensive?
It is a multi-layer product with specialist interlayers, and the frame and installation must suit its weight.
Do you work on occupied buildings in Horsham?
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
