How we approach smoke vent rooflights (AOVs) in Kirkby
Thinking about smoke vent rooflights (AOVs) in Kirkby? 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.
Stone and brick terraces are typical across the North West, and roof windows in rear slopes are a common way to light attic rooms. In Kirkby, as anywhere, smoke vent rooflights (AOVs) are the usual choice for blocks of flats and commercial buildings with a smoke strategy.
Jobs in Kirkby 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
- Control panel with battery backup
- Electric (24 V) or pneumatic actuation
- Glazed rooflight or louvred vent
- Service and test plans
- Rain and wind sensors for daily vent use
- Manual override at the fire service access level
- Glazed units bring daylight to stairwells
Before you order: points to check
- Replacing a vent with a non-equivalent product can affect the fire strategy
- Smoke ventilation is designed to the building's fire strategy — we install to that design
Rules and responsibilities in Kirkby
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.
Read the planning permission guide before you commit to a design.
