Smoke vent rooflights (AOVs) in Lowestoft: what is involved?
We handle smoke vent rooflights (AOVs) across Suffolk, including Lowestoft. In short: automatic smoke ventilators at the head of stairwells and atria. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Barn conversions and timber-framed homes across the East often call for conservation rooflights or bespoke glass. Typical uses for smoke vent rooflights (AOVs) include blocks of flats and commercial buildings with a smoke strategy.
We work across Suffolk, including Lowestoft, and in neighbouring towns such as Great Yarmouth and Norwich. Access, parking and how the glass reaches the roof are all checked at the survey.
