What do smoke vent rooflights (AOVs) in Southport involve?
Thinking about smoke vent rooflights (AOVs) in Southport? 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.
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.
We work across Merseyside, including Southport, and in neighbouring towns such as Formby and Lytham St Annes. Access, parking and how the glass reaches the roof are all checked at the survey.
Specification options
- Break-glass and smoke-detector triggers
- Rain and wind sensors for daily vent use
- Control panel with battery backup

Before you order: points to check
- The product should be certified to BS EN 12101-2 as a natural smoke and heat exhaust ventilator
- Whoever holds the building's fire-safety duties (the responsible person, the duty holder in Scotland or the appropriate person in Northern Ireland) must keep systems maintained and tested
Building control and safety duties in Southport
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. Fragile-roof safety and access are planned before work starts.
