What's involved with fire-resistant glass in Chippenham
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
- Intumescent glazing seals, tapes and gaskets to the tested specification
- Integrity with radiation control (EW) laminated glass
- Integrity (E) glass: modified toughened, glass-ceramic and polished wired types

Key checks for Chippenham projects
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.
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 to fire-resistant glass in Chippenham?
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: Chippenham questions
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.
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.
How quickly can you survey in Chippenham?
Survey timing in Chippenham depends on access, the size of the building and how urgent the defect is. Tell us your deadline when you enquire and we will confirm a date before you commit.
Which rules apply to fire-rated glazing in Chippenham?
Building work in Chippenham follows the Building Regulations 2010 and Approved Document B, and occupied buildings are covered by the Regulatory Reform (Fire Safety) Order 2005.
