What our fire-resistant glass service includes in South Glamorgan
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.
- Impact-classified build-ups for critical locations
- Integrity with radiation control (EW) laminated glass
- Glazing beads and fixings to the frame manufacturer's details
What to check before ordering in South Glamorgan
Inside or outside?
Many insulating fire glasses use interlayers that need protecting from UV and moisture, so external positions need a product approved for exterior use, with the right edge seal and glazing system.
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.
Marking and records
Most fire glass is permanently marked with its product and classification. We record the marks, pane sizes and evidence references on handover so whoever is responsible for fire safety can show what is installed.

Which rules apply 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.
Questions from South Glamorgan clients
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.
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.
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.
Which parts of South Glamorgan do you cover?
