Sudbury fire-resistant glass
Fire-resistant glass in Sudbury is usually needed for one of three reasons: new building work, a change to an existing fire-resisting wall, or defects found in an inspection. We handle all three.

What our fire-resistant glass service includes in Sudbury
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.
- Intumescent glazing seals, tapes and gaskets to the tested specification
- Glazing beads and fixings to the frame manufacturer's details
- Integrity with radiation control (EW) laminated glass
- Insulating (EI) intumescent-interlayer and gel-filled glass

What to check before ordering fire-resistant glass in Sudbury
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.
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.
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.

Which rules apply to fire-resistant glass in Sudbury?
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: Sudbury questions
Is toughened glass fire-resistant?
Ordinary toughened safety glass is not. It can shatter early in a fire. Fire-resistant integrity glass is specially processed or formulated and only gains a rating when fitted in a tested frame and glazing system.
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 Sudbury?
Yes. We survey and install in Sudbury and across Suffolk, including the CO10 district and nearby Colchester.
Do you work on occupied buildings in Sudbury?
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
