How we approach smoke vent rooflights (AOVs) in Johnstone
We handle smoke vent rooflights (AOVs) across Renfrewshire and Inverclyde, including Johnstone. 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.
Tenements and flats are common in Scottish towns and cities, where rooflights over stairwells and top-floor flats need the owners' and factor's agreement. Typical uses for smoke vent rooflights (AOVs) include communal stairwells, corridors and atria.
Neighbouring towns include Paisley (5 km) and Erskine (9 km). We offer a survey date when we reply to your enquiry.

Regulations for smoke vent rooflights (AOVs) in Johnstone
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 install to the building's fire strategy and the manufacturer's certification.
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
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.
How often should AOVs be tested?
Industry guidance recommends regular functional checks and at least annual servicing. Your fire risk assessment sets the regime.
