How we approach smoke vent rooflights (AOVs) in Dover
Thinking about smoke vent rooflights (AOVs) in Dover? 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.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Typical uses for smoke vent rooflights (AOVs) include blocks of flats and commercial buildings with a smoke strategy.
Dover sits about 11 km from Folkestone and 13 km from Deal, and we cover the whole CT16 postcode district and the roads in between.
