How we approach smoke vent rooflights (AOVs) in Wymondham
Thinking about smoke vent rooflights (AOVs) in Wymondham? 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.
In the East of England, bungalows and chalet bungalows with large flat-roofed extensions are common, and they often suit a long run of rooflights. Typical uses for smoke vent rooflights (AOVs) include communal stairwells, corridors and atria.
Wymondham is around 14 km from Norwich, and we survey and fit throughout that part of Norfolk, including the NR18 district.

Questions about smoke vent rooflights (AOVs) in Wymondham
Who is responsible for maintaining smoke vents?
The responsible person (or duty holder in Scotland, appropriate person in Northern Ireland) for the building must keep fire safety systems maintained. We can arrange servicing and keep records.
Do smoke vents need a control panel?
Electric AOVs work with a control panel that links them to detectors, the fire alarm and override switches.
How often should AOVs be tested?
Industry guidance recommends regular functional checks and at least annual servicing. Your fire risk assessment sets the regime.
Can you work alongside my builder in Wymondham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
