What our fire-resistant glass service includes in Portsmouth
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.
- Insulating (EI) intumescent-interlayer and gel-filled glass
- Intumescent glazing seals, tapes and gaskets to the tested specification
- Impact-classified build-ups for critical locations
- Integrity with radiation control (EW) laminated glass
Before you order fire-resistant glass: what matters
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.

England Which rules apply?

The Fire Safety (England) Regulations 2022 add duties for multi-occupied residential buildings, including fire door checks in buildings over 11 metres.

Questions about fire-resistant glass in Portsmouth
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.
Do you supply fire glass only?
Our service is supply and installation, because the rating depends on how the glass is fitted. For trade buyers we can quote supply of cut-to-size panes with the matching glazing materials on request.
Do you carry out fire-resistant glass in Portsmouth?
Yes. We survey and install in Portsmouth and across Hampshire, including the PO5 district and nearby Gosport.
Do you work on occupied buildings in Portsmouth?
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
