What our fire-resistant glass service includes in Bushey
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 (E) glass: modified toughened, glass-ceramic and polished wired types
- Insulating (EI) intumescent-interlayer and gel-filled glass

Key checks for Bushey projects
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.
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: Bushey questions
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.
How thick is fire-resistant glass?
Integrity glass can be similar in thickness to standard glass. Insulating glass is laminated from several layers, so it gets markedly thicker and heavier as the rating increases from EI 30 to EI 120.
Can you price fire-resistant glass in Bushey 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.
Which rules apply to fire-rated glazing in Bushey?
Building work in Bushey follows the Building Regulations 2010 and Approved Document B, and occupied buildings are covered by the Regulatory Reform (Fire Safety) Order 2005.
