What our insulated fire glass service includes in Ewell
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
- Matched glazing systems and seals
- Insulating glass in sealed double-glazed units
- EI 30, EI 60, EI 90 and EI 120 glass

Before you order insulated fire glass: what matters
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.
How it works
When heated, the interlayers turn opaque and expand, forming an insulating shield. After a fire the glass will need replacing.
Fire glazing rules in England
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.

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.
Do you work on occupied buildings in Ewell?
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
Do you carry out insulated fire glass in Ewell?
Yes. We survey and install in Ewell and across Surrey, including the KT17 district and nearby Epsom.
