Smoke vent rooflights (AOVs) for Bolton: the essentials
Thinking about smoke vent rooflights (AOVs) in Bolton? 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. In Bolton, as anywhere, smoke vent rooflights (AOVs) are the usual choice for communal stairwells, corridors and atria.
From Bolton to Farnworth, Westhoughton and Radcliffe, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- Break-glass and smoke-detector triggers
- Service and test plans
- Rain and wind sensors for daily vent use
- Glazed rooflight or louvred vent
- Electric (24 V) or pneumatic actuation
- Replacement of failed or obsolete units
- Opens automatically on alarm signal
What to check first
- 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
- Replacing a vent with a non-equivalent product can affect the fire strategy
Rules and responsibilities in Bolton
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.
Read the planning permission guide before you commit to a design.
