What's involved with insulated fire glass in Guildford
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.
- Impact-classified insulating glass
- Internal and external-grade build-ups
- EI 30, EI 60, EI 90 and EI 120 glass
- Handling and installation of heavy panes
How we work in Guildford
Evidence you can file
You receive the classification references, glass marks and installation photographs for your fire safety records.
England rules applied
Designs follow the building and fire safety rules that apply in England, not a one-size-fits-all approach.
Fixed written quotes
After survey you get a fixed written quote for the agreed scope, so Guildford budgets are not open-ended.
Key checks for Guildford 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.
Exterior positions
Some EI products are internal only. External use needs a product and edge seal approved for UV and weather.
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.
Guildford coverage and nearby towns
Survey visits can be arranged anywhere in Guildford, including the GU1, GU2, GU4 districts, and in nearby Godalming, Woking, Aldershot. Guildford lies roughly 9 km from Woking, within our Surrey coverage.

England regulations that shape the job
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.
Guildford building types
Insulated fire glass applies to many building types in Guildford, including offices and public buildings.
