What's involved with insulated fire glass in Belper
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.
- EI 30, EI 60, EI 90 and EI 120 glass
- Matched glazing systems and seals
- Insulating glass in sealed double-glazed units
- Handling and installation of heavy panes

England rules applied
Designs follow the building and fire safety rules that apply in England, not a one-size-fits-all approach.

Honest about unknowns
If an existing frame in a Belper building has no traceable evidence, we say so and price the options rather than guess.
Key checks for Belper projects
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.
Optical quality
Modern EI glass is clear in normal use, with high light transmission at lower ratings.
Storage on site
Insulating fire glass should be stored dry, upright and away from direct sun before fitting.

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.
