Insulated Fire Glass (EI) — Croydon and CR0
Insulated fire glass in Croydon is usually needed for one of three reasons: new building work, a change to an existing fire-resisting wall, or defects found in an inspection. We handle all three.

What's involved with insulated fire glass in Croydon
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
- EI 30, EI 60, EI 90 and EI 120 glass
- Internal and external-grade build-ups
- Impact-classified insulating glass
Key checks for Croydon projects
How it works
When heated, the interlayers turn opaque and expand, forming an insulating shield. After a fire the glass will need replacing.
Optical quality
Modern EI glass is clear in normal use, with high light transmission at lower ratings.
Exterior positions
Some EI products are internal only. External use needs a product and edge seal approved for UV and weather.

England regulations that shape the job
England Which rules apply?
Building work in England is covered by the Building Regulations 2010, with fire safety guidance in Approved Document B and impact safety guidance for glazing in Approved Document K.
Once a building is in use, the Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to maintain fire safety measures, including fire-resisting glazing. The Fire Safety (England) Regulations 2022 add duties for multi-occupied residential buildings, including fire door checks in buildings over 11 metres.
In higher-risk buildings, broadly 18 metres or seven storeys with two or more homes, the Building Safety Regulator is the building control authority. England is also phasing out BS 476 references from Approved Document B, with the remaining fire-resistance references due to go in September 2029.

Questions about insulated fire glass in Croydon
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.
Is EI glass clear?
Yes, in normal conditions. It turns opaque only when heated in a fire.
Do you carry out insulated fire glass in Croydon?
Yes. We survey and install in Croydon and across Greater London, including the CR0 district and nearby South Croydon.
Do you work on occupied buildings in Croydon?
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
