Insulated Fire Glass (EI) in Cwmbran: what's included
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.
- Insulating glass in sealed double-glazed units
- Internal and external-grade build-ups
- Impact-classified insulating glass
- Matched glazing systems and seals
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.
Storage on site
Insulating fire glass should be stored dry, upright and away from direct sun before fitting.
Optical quality
Modern EI glass is clear in normal use, with high light transmission at lower ratings.

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.
Wales is introducing its own building safety regime for occupied residential buildings, so check current Welsh requirements before planning major works to blocks of flats.

Questions about insulated fire glass in Cwmbran
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.
Does EI glass need replacing after a fire?
Yes. Once the interlayers have reacted, the glass has done its job and must be replaced.
Do you work on occupied buildings in Cwmbran?
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
Do you carry out insulated fire glass in Cwmbran?
Yes. We survey and install in Cwmbran and across Gwent, including the NP44 district and nearby Pontypool.
