Smoke vent rooflights (AOVs) for Deeside: the essentials
Thinking about smoke vent rooflights (AOVs) in Deeside? 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.
Slate roofs, stone cottages and terraced valleys are typical across Wales, and slim rooflights that sit low in the slates suit them best. Smoke vent rooflights (AOVs) suit blocks of flats and commercial buildings with a smoke strategy.
From Deeside to Hawarden, Buckley and Flint, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Deeside
- Glazed rooflight or louvred vent
- Control panel with battery backup

- Electric (24 V) or pneumatic actuation

What to check first

Building control and safety duties in Deeside
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 install to the building's fire strategy and the manufacturer's certification.
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. Fire classification of rooflight materials near boundaries is checked at specification.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
How often should AOVs be tested?
Industry guidance recommends regular functional checks and at least annual servicing. Your fire risk assessment sets the regime.
Do you design the smoke strategy?
No — the strategy comes from the building's fire engineer or designer. We supply, install, commission and service to it.
Can you replace an old smoke vent?
Yes, with an equivalent certified unit that matches the original design area and performance, so the fire strategy is not compromised.
Can you work alongside my builder in Deeside?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Deeside?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
