What our fire-rated curtain walling service includes in Gwynedd
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.
- External-grade fire glass
- Handover evidence for the building record
- Spandrel and opaque panel coordination
Before you order in Gwynedd
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.
Slab edges
The gap between the curtain wall and each floor slab needs fire-stopping designed with the facade, not added afterwards.
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.
Regulations for Gwynedd projects
Wales Which rules apply?
Building regulations are devolved in Wales, so fire safety design follows the Welsh Ministers' version of Approved Document B rather than the English one, alongside impact safety guidance for glazing.
The Regulatory Reform (Fire Safety) Order 2005 applies in Wales, so the responsible person must maintain fire-resisting glazing as part of the premises' fire safety measures. The Fire Safety Act 2021 confirmed this extends to the structure, external walls and flat entrance doors of multi-occupied residential buildings.
Wales is introducing its own building safety regime for occupied residential buildings, so check current Welsh requirements before planning major works to blocks of flats.
