How we approach smoke vent rooflights (AOVs) in Woodford Green
Smoke vent rooflights (AOVs) in Woodford Green means automatic smoke ventilators at the head of stairwells and atria. We cover the IG8 district and the rest of Greater London, with a survey before any price is fixed.
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.
Jobs in Woodford Green 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.

What to check first

Rules and responsibilities in Woodford Green
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. Fire classification of rooflight materials near boundaries is checked at specification.
