Smoke vent rooflights (AOVs) in South Ockendon: what is involved?
Thinking about smoke vent rooflights (AOVs) in South Ockendon? 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.
Flat, open landscape in much of the East means roofs take the wind, so upstand and seal details matter more than the brand of glass. Smoke vent rooflights (AOVs) suit communal stairwells, corridors and atria.
