How we approach smoke vent rooflights (AOVs) in Acton
For Acton 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.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. Smoke vent rooflights (AOVs) suit blocks of flats and commercial buildings with a smoke strategy.
We work across Greater London, including Acton, and in neighbouring towns such as Chiswick and Hammersmith. Access, parking and how the glass reaches the roof are all checked at the survey.

Things we check at survey
- 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
