What our insulated fire glass service includes in Kettering
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.
- Matched glazing systems and seals
- Insulating glass in sealed double-glazed units
- Internal and external-grade build-ups
- Impact-classified insulating glass
What you can expect in Kettering
Rated systems, not just rated glass
Every quote in Kettering identifies the tested system: frame, glass, beads, seals and fixings, within its pane-size limits.
Honest about unknowns
If an existing frame in a Kettering building has no traceable evidence, we say so and price the options rather than guess.
Evidence you can file
You receive the classification references, glass marks and installation photographs for your fire safety records.
Before you order insulated fire glass: what matters
Exterior positions
Some EI products are internal only. External use needs a product and edge seal approved for UV and weather.
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.
How it works
When heated, the interlayers turn opaque and expand, forming an insulating shield. After a fire the glass will need replacing.

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.
Sectors we cover in Kettering
