Fire-Rated Curtain Walling
Fire-rated curtain walling is a glazed facade system tested to resist fire, used where an external wall has to stop fire spreading to a neighbouring building, between floors, or past a protected stair or lobby. It combines facade performance, such as weather tightness and thermal values, with a fire classification.

What does our fire-rated curtain walling service include?
We supply and install fire-rated curtain walling and fire-rated zones within standard curtain walling, alongside the fire-stopping at slab edges. External wall work is closely scrutinised after recent regulatory changes, so every element we fit is backed by evidence for its position.
- Tested fire-rated curtain wall systems
- Fire-rated zones within mixed facades
- External-grade fire glass
- Slab-edge fire-stopping and cavity barriers to the design
- Spandrel and opaque panel coordination
- Handover evidence for the building record
What should you check before ordering?
Boundaries
External walls close to a boundary may need to be fire-resisting with limited unprotected areas. Fixed glazing that meets the wall's full fire-resistance requirement, including insulation where required, is not counted as unprotected area, so it can let you keep glass in those positions.
External-grade glass
External fire glass must be suitable for UV and weather exposure, usually in a sealed double-glazed unit with the fire pane positioned as tested.
Slab edges
The gap between the curtain wall and each floor slab needs fire-stopping designed with the facade, not added afterwards.
Combustibility rules
In England, materials in the external walls of relevant buildings 18 metres or more in height are restricted. We coordinate with the facade designer on every component.
Higher-risk buildings
Work on higher-risk residential buildings in England goes through the Building Safety Regulator, which needs full product evidence at the design stage.
Thermal and acoustic
Fire-rated units can still meet thermal targets when specified correctly; we confirm U-values with the system supplier.
What evidence do you get?
- Facade system fire test or assessment reference
- External glass unit specification
- Slab-edge and cavity barrier details
- Installation records for the building file
Guide prices for fire-rated curtain walling

Frequently asked questions
When does curtain walling need to be fire-rated?
Typically where the facade is near a boundary, where it encloses a protected stair or lobby, or where fire spread between floors has to be controlled. The fire strategy sets the requirement.
Can fire glass be used in double-glazed units?
Yes. External fire-rated glazing is usually supplied as a sealed unit with the fire pane in a tested position.
Do you work on high-rise buildings?
We can supply and install on taller buildings where the project has the required approvals, and we provide evidence suitable for the Building Safety Regulator in England.
Can you add fire-rated zones to existing curtain walling?
Sometimes, if the existing system has a tested fire-rated version. Otherwise a local replacement may be needed.
