What our insulated fire glass service includes in Eltham
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.
- Handling and installation of heavy panes
- Impact-classified insulating glass
- Matched glazing systems and seals
- Internal and external-grade build-ups
What every Eltham quote includes
Honest about unknowns
If an existing frame in a Eltham building has no traceable evidence, we say so and price the options rather than guess.
Evidence you can file
You receive the classification references, glass marks and installation photographs for your fire safety records.
Fixed written quotes
After survey you get a fixed written quote for the agreed scope, so Eltham budgets are not open-ended.
Key checks for Eltham 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.
Exterior positions
Some EI products are internal only. External use needs a product and edge seal approved for UV and weather.
Storage on site
Insulating fire glass should be stored dry, upright and away from direct sun before fitting.

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.
