What do smoke vent rooflights (AOVs) in Maghull involve?
For Maghull 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. Smoke vent rooflights (AOVs) suit blocks of flats and commercial buildings with a smoke strategy.
Maghull sits about 5 km from Kirkby and 6 km from Litherland, and we cover the whole L31 postcode district and the roads in between.
What you can choose
- Break-glass and smoke-detector triggers
- Glazed rooflight or louvred vent
- Rain and wind sensors for daily vent use
- Electric (24 V) or pneumatic actuation
- Control panel with battery backup
- Replacement of failed or obsolete units
- Opens automatically on alarm signal
Things we check at survey
- Replacing a vent with a non-equivalent product can affect the fire strategy
- 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
Rules and responsibilities in Maghull
Smoke vents are life-safety equipment: in England the responsible person must keep them maintained under the Regulatory Reform (Fire Safety) Order 2005. We install to the building's fire strategy and the manufacturer's certification.
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.
