Key checks for Caerphilly projects
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.
Optical quality
Modern EI glass is clear in normal use, with high light transmission at lower ratings.
Storage on site
Insulating fire glass should be stored dry, upright and away from direct sun before fitting.

Fire glazing rules in Wales
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.

FAQs for Caerphilly
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 Caerphilly?
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 Caerphilly?
Survey timing in Caerphilly 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.
