What our fire-rated curtain walling service includes in Durham
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.
- Handover evidence for the building record
- Fire-rated zones within mixed facades
- External-grade fire glass
- Slab-edge fire-stopping and cavity barriers to the design
What to check before ordering fire-rated curtain walling in Durham
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.
Thermal and acoustic
Fire-rated units can still meet thermal targets when specified correctly; we confirm U-values with the system supplier.
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.
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.

FAQs for Durham
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.
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.

Building work in Durham follows the Building Regulations 2010 and Approved Document B, and occupied buildings are covered by the Regulatory Reform (Fire Safety) Order 2005.
