What our insulated fire glass service includes in Trowbridge
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
- Insulating glass in sealed double-glazed units
- EI 30, EI 60, EI 90 and EI 120 glass
- Handling and installation of heavy panes
How we work in Trowbridge
Rated systems, not just rated glass
Every quote in Trowbridge identifies the tested system: frame, glass, beads, seals and fixings, within its pane-size limits.
Fixed written quotes
After survey you get a fixed written quote for the agreed scope, so Trowbridge budgets are not open-ended.
Honest about unknowns
If an existing frame in a Trowbridge building has no traceable evidence, we say so and price the options rather than guess.
Key checks for Trowbridge projects
Exterior positions
Some EI products are internal only. External use needs a product and edge seal approved for UV and weather.
Storage on site
Insulating fire glass should be stored dry, upright and away from direct sun before fitting.
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.
Trowbridge coverage and nearby towns

Which rules apply to insulated fire glass in Trowbridge?
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.

We can give a guide range from photos and sizes, including a clear photo of any marks on the glass. A fixed price follows a survey.
