How we approach smoke vent rooflights (AOVs) in Bordon
Thinking about smoke vent rooflights (AOVs) in Bordon? 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.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Smoke vent rooflights (AOVs) suit communal stairwells, corridors and atria.
We work across Hampshire, including Bordon, and in neighbouring towns such as Farnham and Aldershot. Access, parking and how the glass reaches the roof are all checked at the survey.
