Smoke vent rooflights (AOVs) in Bishop's Stortford: what is involved?
For Bishop's Stortford homes and buildings we offer smoke vent rooflights (AOVs): automatic smoke ventilators at the head of stairwells and atria. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
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 communal stairwells, corridors and atria.
Jobs in Bishop's Stortford 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.
