What are smoke vent rooflights (AOVs)?
Smoke vent rooflights (AOVs) in County Armagh means automatic smoke ventilators at the head of stairwells and atria. Every quote follows a survey of the roof and the room below.
Conservation areas and listed buildings in Northern Ireland are excluded from householder permitted development, so we check before quoting. Northern Ireland has a mix of terraces, bungalows and rural farmhouses, and rooflights are a common upgrade when extending.

Planning and building rules in Northern Ireland
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 supply manufacturer-certified units and arrange installation, commissioning and servicing through specialist smoke-control engineers.
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
Can a smoke vent be used for normal ventilation?
Many dual-purpose units also open for daily ventilation, closing automatically in rain.
Who is responsible for maintaining smoke vents?
The responsible person (or duty holder in Scotland, appropriate person in Northern Ireland) for the building must keep fire safety systems maintained. We can arrange servicing and keep records.
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 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.
Do I need to be at home for the survey in County Armagh?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
