Smoke vent rooflights (AOVs) for Chorley: the essentials
We handle smoke vent rooflights (AOVs) across Lancashire, including Chorley. 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.
The North West gets more rain than most of England, so upstand height, membrane detailing and rain sensors on opening units are not optional extras. Smoke vent rooflights (AOVs) suit blocks of flats and commercial buildings with a smoke strategy.
Chorley sits about 7 km from Leyland and 11 km from Darwen, and we cover the whole PR7 postcode district and the roads in between.
Choices for your Chorley project
- Rain and wind sensors for daily vent use
- Service and test plans
- Glazed rooflight or louvred vent
- Break-glass and smoke-detector triggers
- Electric (24 V) or pneumatic actuation
- Replacement of failed or obsolete units
- Also usable for day-to-day ventilation
Before you order: points to check
- 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
Building control and safety duties in Chorley
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.
