What do smoke vent rooflights (AOVs) in Slough involve?
Smoke vent rooflights (AOVs) in Slough means automatic smoke ventilators at the head of stairwells and atria. We cover the SL1 district and the rest of Berkshire, with a survey before any price is fixed.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Typical uses for smoke vent rooflights (AOVs) include communal stairwells, corridors and atria.
Slough is around 27 km from Reading, and we survey and fit throughout that part of Berkshire, including the SL1 district.
