How we approach smoke vent rooflights (AOVs) in Renfrew
For Renfrew 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.
Short winter days in Scotland make every square metre of overhead glass count, so rooflight sizing matters. Smoke vent rooflights (AOVs) suit communal stairwells, corridors and atria.
Renfrew sits about 3 km from Clydebank and 5 km from Erskine, and we cover the whole PA4 postcode district and the roads in between.
What you can choose
- Service and test plans
- Glazed rooflight or louvred vent
- Control panel with battery backup
- Electric (24 V) or pneumatic actuation
- Rain and wind sensors for daily vent use
- Servicing and testing available
- Manual override at the fire service access level
Things we check at survey
- 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
- The product should be certified to BS EN 12101-2 as a natural smoke and heat exhaust ventilator
Rules and responsibilities in Renfrew
Smoke vents are life-safety equipment: in Scotland the duty holder must keep them maintained under the Fire (Scotland) Act 2005 and the Fire Safety (Scotland) Regulations 2006. We supply manufacturer-certified units and arrange installation, commissioning and servicing through specialist smoke-control engineers.
For non-domestic buildings in Scotland, the non-domestic Technical Handbook (section 6) sets the energy standards for rooflights; we supply the manufacturer's data for the building warrant. 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.
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.
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 I need to be at home for the survey in Renfrew?
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 Renfrew?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
