Smoke vent rooflights (AOVs) in Dungannon: what is involved?
Smoke vent rooflights (AOVs) in Dungannon means automatic smoke ventilators at the head of stairwells and atria. We cover the BT70 district and the rest of County Tyrone, with a survey before any price is fixed.
Bungalows are widespread in Northern Ireland, and sun tunnels or roof windows are an easy way to brighten internal hallways. Smoke vent rooflights (AOVs) suit communal stairwells, corridors and atria.
Jobs in Dungannon are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
What you can choose
- Glazed rooflight or louvred vent
- Service and test plans
- Control panel with battery backup
- Electric (24 V) or pneumatic actuation
- Break-glass and smoke-detector triggers
- Manual override at the fire service access level

What to check first
- Smoke ventilation is designed to the building's fire strategy — we install to that design
- 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
Regulations for smoke vent rooflights (AOVs) in Dungannon
Smoke vents are life-safety equipment: in Northern Ireland the appropriate person must keep them maintained under the Fire and Rescue Services (Northern Ireland) Order 2006 and the Fire Safety Regulations (Northern Ireland) 2010. We install to the building's fire strategy and the manufacturer's certification.
For non-domestic buildings in Northern Ireland, Technical Booklet F2 covers energy performance; we supply the manufacturer's data for building control. Fragile-roof safety and access are planned before work starts.

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 smoke vents need a control panel?
Electric AOVs work with a control panel that links them to detectors, the fire alarm and override switches.
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.
Do I need to be at home for the survey in Dungannon?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Dungannon?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
