What do smoke vent rooflights (AOVs) in Ossett involve?
For Ossett 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.
Stone-built terraces are common across Yorkshire, and roof windows in the rear slope are a popular way to light attic rooms. In Ossett, as anywhere, smoke vent rooflights (AOVs) are the usual choice for blocks of flats and commercial buildings with a smoke strategy.
Jobs in Ossett are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Specification options
- Break-glass and smoke-detector triggers
- Rain and wind sensors for daily vent use

What to check first
- The product should be certified to BS EN 12101-2 as a natural smoke and heat exhaust ventilator
- Smoke ventilation is designed to the building's fire strategy — we install to that design
Regulations for smoke vent rooflights (AOVs) in Ossett
Smoke vents are life-safety equipment: in England the responsible person must keep them maintained under the Regulatory Reform (Fire Safety) Order 2005. We supply manufacturer-certified units and arrange installation, commissioning and servicing through specialist smoke-control engineers.
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. Fire classification of rooflight materials near boundaries is checked at specification.
See our building regulations guide for U-values, glazing limits and self-certification.
