Insulated Fire Glass (EI): what you get in Lancashire
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
- Handling and installation of heavy panes
- Impact-classified insulating glass
Key checks for Lancashire projects
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.
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.
Regulations for Lancashire projects
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 from Lancashire clients
Does EI glass need replacing after a fire?
Yes. Once the interlayers have reacted, the glass has done its job and must be replaced.
Can EI glass be used outside?
Only products approved for external use, usually in a sealed unit with UV protection.
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.
