How we approach smoke vent rooflights (AOVs) in Thornton-Cleveleys
For Thornton-Cleveleys 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.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. In Thornton-Cleveleys, as anywhere, smoke vent rooflights (AOVs) are the usual choice for blocks of flats and commercial buildings with a smoke strategy.
Jobs in Thornton-Cleveleys 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.

Building control and safety duties in Thornton-Cleveleys
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. Fragile-roof safety and access are planned before work starts.
Read the planning permission guide before you commit to a design.
