Fire-Resistant Glass for Richmond buildings
If a building in Richmond needs fire-resistant glass, the starting point is the rating its fire strategy requires. We confirm that, survey the openings and quote a tested system to suit.

Fire-Resistant Glass in Richmond: what's included
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
- Glazing beads and fixings to the frame manufacturer's details
- Impact-classified build-ups for critical locations
- Integrity (E) glass: modified toughened, glass-ceramic and polished wired types

Before you order fire-resistant glass: what matters
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.
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 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.
England regulations that shape the job
England Which rules apply?
Building work in England is covered by the Building Regulations 2010, with fire safety guidance in Approved Document B and impact safety guidance for glazing in Approved Document K.
Once a building is in use, the Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to maintain fire safety measures, including fire-resisting glazing. The Fire Safety (England) Regulations 2022 add duties for multi-occupied residential buildings, including fire door checks in buildings over 11 metres.
How we work in Richmond
Rated systems, not just rated glass
Every quote in Richmond identifies the tested system: frame, glass, beads, seals and fixings, within its pane-size limits.
Honest about unknowns
If an existing frame in a Richmond building has no traceable evidence, we say so and price the options rather than guess.
Evidence you can file
You receive the classification references, glass marks and installation photographs for your fire safety records.

Fire-Resistant Glass: Richmond questions
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.
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 work on occupied buildings in Richmond?
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
Do you carry out fire-resistant glass in Richmond?
Yes. We survey and install in Richmond and across Greater London, including the TW9 district and nearby Isleworth.
