Insulated Fire Glass (EI): an overview for Cumbria
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.
- Impact-classified insulating glass
- Internal and external-grade build-ups
- Insulating glass in sealed double-glazed units
Before you order in Cumbria
Storage on site
Insulating fire glass should be stored dry, upright and away from direct sun before fitting.
Exterior positions
Some EI products are internal only. External use needs a product and edge seal approved for UV and weather.
How it works
When heated, the interlayers turn opaque and expand, forming an insulating shield. After a fire the glass will need replacing.
Which rules apply 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.

Insulated Fire Glass (EI) in Cumbria: questions
Does EI glass need replacing after a fire?
Yes. Once the interlayers have reacted, the glass has done its job and must be replaced.
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.
Is EI glass clear?
Yes, in normal conditions. It turns opaque only when heated in a fire.
Do you cover all of Cumbria?
Yes. We take enquiries from across Cumbria, including Carlisle and Barrow-in-Furness, Kendal, Whitehaven, Workington, and arrange surveys to suit your programme.
