Insulated Fire Glass (EI) in Barnstaple: what's included
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.
- Internal and external-grade build-ups
- Impact-classified insulating glass
- Handling and installation of heavy panes
- Matched glazing systems and seals
What to check before ordering insulated fire glass in Barnstaple
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.
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): Barnstaple questions
Does EI glass need replacing after a fire?
Yes. Once the interlayers have reacted, the glass has done its job and must be replaced.
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.
Which rules apply to fire-rated glazing in Barnstaple?
Building work in Barnstaple follows the Building Regulations 2010 and Approved Document B, and occupied buildings are covered by the Regulatory Reform (Fire Safety) Order 2005.
Do you work on occupied buildings in Barnstaple?
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
