What do smoke vent rooflights (AOVs) in Dinas Powys involve?
Thinking about smoke vent rooflights (AOVs) in Dinas Powys? The short answer: automatic smoke ventilators at the head of stairwells and atria. The longer answer depends on your roof, which is why we survey before we price.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting. Smoke vent rooflights (AOVs) suit blocks of flats and commercial buildings with a smoke strategy.
Dinas Powys is around 6 km from Cardiff, and we survey and fit throughout that part of South Glamorgan, including the CF64 district.
What you can choose
- Glazed rooflight or louvred vent
- Rain and wind sensors for daily vent use

Before you order: points to check
- Whoever holds the building's fire-safety duties (the responsible person, the duty holder in Scotland or the appropriate person in Northern Ireland) must keep systems maintained and tested
- Smoke ventilation is designed to the building's fire strategy — we install to that design
Regulations for smoke vent rooflights (AOVs) in Dinas Powys
Smoke vents are life-safety equipment: in Wales the responsible person must keep them maintained under the Regulatory Reform (Fire Safety) Order 2005 (as it applies in Wales). We supply manufacturer-certified units and arrange installation, commissioning and servicing through specialist smoke-control engineers.
For non-domestic buildings in Wales, Approved Document L sets limiting U-values for rooflights and roof ventilators; we supply the manufacturer's data for the building control submission. Fragile-roof safety and access are planned before work starts.
Read the planning permission guide before you commit to a design.
