What our insulated fire glass service includes in Swansea
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
- Insulating glass in sealed double-glazed units
- EI 30, EI 60, EI 90 and EI 120 glass
- Internal and external-grade build-ups
What to check before ordering insulated fire glass in Swansea
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.
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.

Wales regulations that shape the job
Wales Which rules apply?
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.
Swansea building types
We can survey and quote for schools and colleges, offices and other building types in Swansea.
Questions about insulated fire glass in Swansea
Is EI glass clear?
Yes, in normal conditions. It turns opaque only when heated in a fire.
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.
Do you work on occupied buildings in Swansea?
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
How quickly can you survey in Swansea?
Survey timing in Swansea depends on access, the size of the building and how urgent the defect is. Tell us your deadline when you enquire and we will confirm a date before you commit.
