What our fire-resistant glass service includes in Hitchin
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.
- Impact-classified build-ups for critical locations
- Glazing beads and fixings to the frame manufacturer's details
- Integrity (E) glass: modified toughened, glass-ceramic and polished wired types
- Integrity with radiation control (EW) laminated glass
Before you order fire-resistant glass: what matters
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.
Inside or outside?
Many insulating fire glasses use interlayers that need protecting from UV and moisture, so external positions need a product approved for exterior use, with the right edge seal and glazing system.
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.
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: Hitchin 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.
Can you price fire-resistant glass in Hitchin from photos?
We can give a guide range from photos and sizes, including a clear photo of any marks on the glass. A fixed price follows a survey.
Do you carry out fire-resistant glass in Hitchin?
Yes. We survey and install in Hitchin and across Hertfordshire, including the SG4 district and nearby Letchworth Garden City.
