What do smoke vent rooflights (AOVs) in Dronfield involve?
For Dronfield 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.
Industrial and commercial units around Midlands towns often still have their original rooflight sheets, which are due for replacement. Smoke vent rooflights (AOVs) suit communal stairwells, corridors and atria.
Dronfield is around 42 km from Derby, and we survey and fit throughout that part of Derbyshire, including the S18 district.

Building control and safety duties in Dronfield
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.
