What's involved with fire-rated curtain walling in Portsmouth
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
- Spandrel and opaque panel coordination
- Tested fire-rated curtain wall systems
- Fire-rated zones within mixed facades
What to check before ordering fire-rated curtain walling in Portsmouth
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.
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.
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.

FAQs for Portsmouth
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 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.
Do you work on occupied buildings in Portsmouth?
Yes. We plan phasing, out-of-hours work and temporary protection so the building can stay in use where the fire strategy allows.
Which rules apply to fire-rated glazing in Portsmouth?
Building work in Portsmouth follows the Building Regulations 2010 and Approved Document B, and occupied buildings are covered by the Regulatory Reform (Fire Safety) Order 2005.
