What do smoke vent rooflights (AOVs) in Lisburn involve?
We handle smoke vent rooflights (AOVs) across County Antrim, including Lisburn. In short: automatic smoke ventilators at the head of stairwells and atria. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Conservation areas and listed buildings in Northern Ireland are excluded from householder permitted development, so we check before quoting. Typical uses for smoke vent rooflights (AOVs) include communal stairwells, corridors and atria.
Lisburn sits about 11 km from Belfast and 11 km from Castlereagh, and we cover the whole BT27 postcode district and the roads in between.

Before you order: points to check
- 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
Building control and safety duties in Lisburn
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.
Read the planning permission guide before you commit to a design.

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.
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.

Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
