Fire-Resistant Glass: what you get in Gwynedd
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 with radiation control (EW) laminated glass
- Insulating (EI) intumescent-interlayer and gel-filled glass
- Impact-classified build-ups for critical locations

Key checks for Gwynedd projects
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.
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.
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.
Regulations for Gwynedd projects
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.
Fire-Resistant Glass in Gwynedd: questions
Is toughened glass fire-resistant?
Ordinary toughened safety glass is not. It can shatter early in a fire. Fire-resistant integrity glass is specially processed or formulated and only gains a rating when fitted in a tested frame and glazing system.
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.
What is the difference between E, EW and EI fire glass?
E is integrity only: it stops flames and hot gases passing for the rated time. EW adds a limit on radiated heat through the glass. EI adds insulation, keeping the unexposed face below set temperature rises so people can pass it safely. The number after the letters is the time in minutes.
