Insulated Fire Glass (EI) — Dover and CT16
Insulated fire glass in Dover is usually needed for one of three reasons: new building work, a change to an existing fire-resisting wall, or defects found in an inspection. We handle all three.

Insulated Fire Glass (EI) in Dover: what's included
EI glass is the choice where people need to pass close to the glass during a fire, where combustible materials sit near it, or where building guidance would otherwise restrict glazing. We supply and fit EI 30 to EI 120 glass in tested frames, internally and externally.
- Internal and external-grade build-ups
- EI 30, EI 60, EI 90 and EI 120 glass
- Insulating glass in sealed double-glazed units
- Handling and installation of heavy panes
Key checks for Dover projects
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.
Storage on site
Insulating fire glass should be stored dry, upright and away from direct sun before fitting.

Which rules apply to insulated fire glass in Dover?
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.
Sectors we cover in Dover
Insulated fire glass applies to many building types in Dover, including blocks of flats and industrial units.
Insulated Fire Glass (EI): Dover questions
Is EI glass clear?
Yes, in normal conditions. It turns opaque only when heated in a fire.
Can EI glass be used outside?
Only products approved for external use, usually in a sealed unit with UV protection.
Do you carry out insulated fire glass in Dover?
Yes. We survey and install in Dover and across Kent, including the CT16 district and nearby Folkestone.
Do you work on occupied buildings in Dover?
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
