Fire-Resistant Glass in Sunbury-on-Thames: 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.
- Glazing beads and fixings to the frame manufacturer's details
- Integrity with radiation control (EW) laminated glass
- Integrity (E) glass: modified toughened, glass-ceramic and polished wired types
- Intumescent glazing seals, tapes and gaskets to the tested specification

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.
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.
Fire glazing rules in England
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.
In higher-risk buildings, broadly 18 metres or seven storeys with two or more homes, the Building Safety Regulator is the building control authority. England is also phasing out BS 476 references from Approved Document B, with the remaining fire-resistance references due to go in September 2029.

Fire-Resistant Glass: Sunbury-on-Thames 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.
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 work on occupied buildings in Sunbury-on-Thames?
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
Which rules apply to fire-rated glazing in Sunbury-on-Thames?
Building work in Sunbury-on-Thames follows the Building Regulations 2010 and Approved Document B, and occupied buildings are covered by the Regulatory Reform (Fire Safety) Order 2005.
