How we approach smoke vent rooflights (AOVs) in Yeovil
For Yeovil 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.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. In Yeovil, as anywhere, smoke vent rooflights (AOVs) are the usual choice for communal stairwells, corridors and atria.
Jobs in Yeovil 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.
What you can choose
- Electric (24 V) or pneumatic actuation
- Control panel with battery backup
- Rain and wind sensors for daily vent use
- Break-glass and smoke-detector triggers
- Service and test plans
- Replacement of failed or obsolete units
- Also usable for day-to-day ventilation
Things we check at survey
- Replacing a vent with a non-equivalent product can affect the fire strategy
- The product should be certified to BS EN 12101-2 as a natural smoke and heat exhaust ventilator
Regulations for smoke vent rooflights (AOVs) in Yeovil
