Fire-Resistant Glass in Cardiff: what's included
We supply and fit fire-resistant glass into new and existing fire-rated frames, matching the glass type, thickness, beads, seals and fixings to the test or assessment evidence for that frame. The glass on its own does not carry a rating; the combination does, so we start every job by identifying the system you have or need.
- Integrity (E) glass: modified toughened, glass-ceramic and polished wired types
- Intumescent glazing seals, tapes and gaskets to the tested specification
- Integrity with radiation control (EW) laminated glass
- Impact-classified build-ups for critical locations
What every Cardiff quote includes
Rated systems, not just rated glass
Every quote in Cardiff identifies the tested system: frame, glass, beads, seals and fixings, within its pane-size limits.
Fixed written quotes
After survey you get a fixed written quote for the agreed scope, so Cardiff budgets are not open-ended.
Evidence you can file
You receive the classification references, glass marks and installation photographs for your fire safety records.
What to check before ordering fire-resistant glass in Cardiff
Can any fire glass go in any fire-rated frame?
No. A frame is only rated with the glass types and pane sizes it was tested or assessed with. We check the frame's evidence before quoting, and if the existing frame is unknown we say so and price the options.
Which classification do you actually need?
The fire strategy or building control drawings set the rating for each element. Integrity-only glass is cheaper and thinner, but its use on escape routes is restricted; insulating glass carries far fewer restrictions because people can pass it safely during a fire.
Impact safety still applies
Glass in doors, side panels and low-level positions has to meet impact safety rules as well as the fire rating. Most modern fire glass carries an impact classification; old wired glass usually does not.

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.
Building types we cover in Cardiff
Fire-resistant glass applies to many building types in Cardiff, including retail and leisure units and student accommodation.
Questions about fire-resistant glass in Cardiff
Can you match glass that is already installed?
Often, yes. We read the marks on the existing panes and check them against the frame evidence. Where the original product is discontinued we look for an alternative covered by the same evidence or a formal assessment.
How thick is fire-resistant glass?
Integrity glass can be similar in thickness to standard glass. Insulating glass is laminated from several layers, so it gets markedly thicker and heavier as the rating increases from EI 30 to EI 120.
Do you carry out fire-resistant glass in Cardiff?
Yes. We survey and install in Cardiff and across South Glamorgan, including the CF10 district and nearby Penarth.
How quickly can you survey in Cardiff?
Survey timing in Cardiff 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.
