What our insulated fire glass service includes in Great Yarmouth
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.
- Insulating glass in sealed double-glazed units
- Internal and external-grade build-ups
- Matched glazing systems and seals
- Handling and installation of heavy panes
Before you order insulated fire glass: what matters
Storage on site
Insulating fire glass should be stored dry, upright and away from direct sun before fitting.
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.

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.
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.
