How we approach smoke vent rooflights (AOVs) in Kingston upon Thames
Thinking about smoke vent rooflights (AOVs) in Kingston upon Thames? The short answer: automatic smoke ventilators at the head of stairwells and atria. The longer answer depends on your roof, which is why we survey before we price.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. Smoke vent rooflights (AOVs) suit communal stairwells, corridors and atria.
Neighbouring towns include Twickenham (3 km) and Richmond (3 km). We offer a survey date when we reply to your enquiry.
