Insulated Fire Glass (EI) in Sunderland: 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.
- EI 30, EI 60, EI 90 and EI 120 glass
- Insulating glass in sealed double-glazed units
- Matched glazing systems and seals
- Internal and external-grade build-ups
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.
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.
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.

Which rules apply to insulated fire glass in Sunderland?
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.

Questions about insulated fire glass in Sunderland
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.
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.
Do you work on occupied buildings in Sunderland?
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 Sunderland?
Yes. We survey and install in Sunderland and across Tyne and Wear, including the SR1 district and nearby Seaham.
