Fire-Resistant Glass
Integrity and insulating fire glass supplied and fitted into tested frames.
Learn more →For Wrexham buildings, we supply, replace and check insulated fire glass wherever the fire strategy depends on it, working to the tested system rather than the glass alone.

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.
Coverage around Wrexham includes the LL13, LL11 districts and nearby Rhosllannerchrugog, Buckley, Hawarden. Wrexham is the main town we cover in Clwyd.
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.
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.
When heated, the interlayers turn opaque and expand, forming an insulating shield. After a fire the glass will need replacing.
Building regulations are devolved in Wales, so fire safety design follows the Welsh Ministers' version of Approved Document B rather than the English one, alongside impact safety guidance for glazing.
The Regulatory Reform (Fire Safety) Order 2005 applies in Wales, so the responsible person must maintain fire-resisting glazing as part of the premises' fire safety measures. The Fire Safety Act 2021 confirmed this extends to the structure, external walls and flat entrance doors of multi-occupied residential buildings.
After survey you get a fixed written quote for the agreed scope, so Wrexham budgets are not open-ended.
If an existing frame in a Wrexham building has no traceable evidence, we say so and price the options rather than guess.
We can phase work in Wrexham around residents, staff or pupils, with out-of-hours options.
Sector guides below cover public buildings, retail and leisure units and other buildings in Wrexham.
Yes. Once the interlayers have reacted, the glass has done its job and must be replaced.
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.
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.
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
