What our insulated fire glass service includes in Billericay
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.
- Impact-classified insulating glass
- 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
How it works
When heated, the interlayers turn opaque and expand, forming an insulating shield. After a fire the glass will need replacing.
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.
Thickness and weight
Each step up in rating adds layers, so EI 120 is far thicker and heavier than EI 30. The frame has to be designed for it.

England Which rules apply?

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.

Yes. Once the interlayers have reacted, the glass has done its job and must be replaced.

Yes. We survey and install in Billericay and across Essex, including the CM11 district and nearby Basildon.
