What our fire-resistant glass service includes in Cwmbran
Fire-resistant glass is glazing that has been tested, as part of a complete glazed system, to hold back fire for a set time. It is classified by what it stops: E (integrity) keeps flames and hot gases on the fire side, EW also limits the heat radiated through the glass, and EI (integrity and insulation) also limits the temperature rise on the protected side, so people can pass it more safely.
- Insulating (EI) intumescent-interlayer and gel-filled glass
- Integrity (E) glass: modified toughened, glass-ceramic and polished wired types
- Integrity with radiation control (EW) laminated glass
- Intumescent glazing seals, tapes and gaskets to the tested specification

Key checks for Cwmbran projects
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.
Weight and handling
Insulating fire glass gets thicker and heavier as the rating rises. Large EI 60 and EI 120 panes often need lifting equipment and a frame designed for the load, which we plan before the delivery date.
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.
Which rules apply to fire-resistant glass in Cwmbran?
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.

Fire-Resistant Glass: Cwmbran 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.
Which rules apply to fire-rated glazing in Cwmbran?
Cwmbran is in Wales, where the Welsh Approved Document B applies to building work and the Regulatory Reform (Fire Safety) Order 2005 covers occupied premises.
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.
