What do smoke vent rooflights (AOVs) in Formby involve?
For Formby 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.
Converted mills and warehouses in the North West often have large rooflights or glass roofs that need specialist replacement. Think of smoke vent rooflights (AOVs) for blocks of flats and commercial buildings with a smoke strategy.
Jobs in Formby 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
- Rain and wind sensors for daily vent use
- Service and test plans
- Glazed rooflight or louvred vent
- Break-glass and smoke-detector triggers
- Glazed units bring daylight to stairwells
- Opens automatically on alarm signal
What to check first
- Smoke ventilation is designed to the building's fire strategy — we install to that design
- Replacing a vent with a non-equivalent product can affect the fire strategy
Building control and safety duties in Formby
Smoke vents are life-safety equipment: in England the responsible person must keep them maintained under the Regulatory Reform (Fire Safety) Order 2005. We supply manufacturer-certified units and arrange installation, commissioning and servicing through specialist smoke-control engineers.
For buildings other than dwellings, Approved Document L Volume 2 sets limiting U-values of 2.2 W/m²K for rooflights and 3.0 W/m²K for roof ventilators, including smoke vents. Fire classification of rooflight materials near boundaries is checked at specification.
