How we approach smoke vent rooflights (AOVs) in Bentley
For Bentley 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.
Exposed Pennine and coastal towns in Yorkshire need upstand and flashing details built for wind-driven rain. In Bentley, as anywhere, smoke vent rooflights (AOVs) are the usual choice for communal stairwells, corridors and atria.
Bentley sits about 2 km from Doncaster and 18 km from Rotherham, and we cover the whole DN5 postcode district and the roads in between.
Choices for your Bentley project

Before you order: points to check
- 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
Regulations for smoke vent rooflights (AOVs) in Bentley
Smoke vents are life-safety equipment: in England the responsible person must keep them maintained under the Regulatory Reform (Fire Safety) Order 2005. We install to the building's fire strategy and the manufacturer's certification.
For buildings other than dwellings, Approved Document L Volume 2 sets limiting U-values of 2.2 W/m²K for rooflights and 3.0 W/m²K for roof ventilators, including smoke vents. Fragile-roof safety and access are planned before work starts.

Smoke vent rooflights (AOVs) in Bentley: 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 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.
Can a smoke vent be used for normal ventilation?
Many dual-purpose units also open for daily ventilation, closing automatically in rain.
How do I book a survey in Bentley?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Do I need to be at home for the survey in Bentley?
