Smoke vent rooflights (AOVs) in Atherton: what is involved?
Smoke vent rooflights (AOVs) in Atherton means automatic smoke ventilators at the head of stairwells and atria. We cover the M46 district and the rest of Greater Manchester, with a survey before any price is fixed.
Converted mills and warehouses in the North West often have large rooflights or glass roofs that need specialist replacement. Think of smoke vent rooflights (AOVs) for blocks of flats and commercial buildings with a smoke strategy.
Jobs in Atherton 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
- Rain and wind sensors for daily vent use
- Break-glass and smoke-detector triggers
- Electric (24 V) or pneumatic actuation
- Service and test plans
- Also usable for day-to-day ventilation
- Opens automatically on alarm signal
Before you order: points to check
- Smoke ventilation is designed to the building's fire strategy — we install to that design
- 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 Atherton
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.
See our building regulations guide for U-values, glazing limits and self-certification.
