What's involved with insulated fire glass in Barnes
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
- EI 30, EI 60, EI 90 and EI 120 glass
- Internal and external-grade build-ups
Key checks for Barnes projects
Exterior positions
Some EI products are internal only. External use needs a product and edge seal approved for UV and weather.
Optical quality
Modern EI glass is clear in normal use, with high light transmission at lower ratings.
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.

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.

Insulated Fire Glass (EI): Barnes questions
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.
Can EI glass be used outside?
Only products approved for external use, usually in a sealed unit with UV protection.
How quickly can you survey in Barnes?
Survey timing in Barnes depends on access, the size of the building and how urgent the defect is. Tell us your deadline when you enquire and we will confirm a date before you commit.
Do you work on occupied buildings in Barnes?
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
