Fire-Resistant Glass in Cheltenham: 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.
- Integrity with radiation control (EW) laminated glass
- Impact-classified build-ups for critical locations
- Glazing beads and fixings to the frame manufacturer's details
- 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.
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.
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.
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.

Questions about fire-resistant glass in Cheltenham
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.
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 carry out fire-resistant glass in Cheltenham?
Yes. We survey and install in Cheltenham and across Gloucestershire, including the GL50 district and nearby Tewkesbury.
Do you work on occupied buildings in Cheltenham?
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
