How we approach smoke vent rooflights (AOVs) in Pwllheli
For Pwllheli homes and buildings we offer smoke vent rooflights (AOVs): automatic smoke ventilators at the head of stairwells and atria. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. Typical uses for smoke vent rooflights (AOVs) include communal stairwells, corridors and atria.
We work across Gwynedd, including Pwllheli, and in neighbouring towns such as Porthmadog and Caernarfon. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Glazed rooflight or louvred vent
- Control panel with battery backup
- Service and test plans
- Electric (24 V) or pneumatic actuation
- Break-glass and smoke-detector triggers
- Opens automatically on alarm signal
- Glazed units bring daylight to stairwells
What to check first
- Replacing a vent with a non-equivalent product can affect the fire strategy
- 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
Building control and safety duties in Pwllheli
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. 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
Can a smoke vent be used for normal ventilation?
Many dual-purpose units also open for daily ventilation, closing automatically in rain.
Do smoke vents need a control panel?
Electric AOVs work with a control panel that links them to detectors, the fire alarm and override switches.
How often should AOVs be tested?
Industry guidance recommends regular functional checks and at least annual servicing. Your fire risk assessment sets the regime.
How do I book a survey in Pwllheli?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Pwllheli?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
