How we approach smoke vent rooflights (AOVs) in Chadderton
We handle smoke vent rooflights (AOVs) across Greater Manchester, including Chadderton. 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. Typical uses for smoke vent rooflights (AOVs) include communal stairwells, corridors and atria.
From Chadderton to Oldham, Royton and Failsworth, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Chadderton
- Rain and wind sensors for daily vent use
- Service and test plans
- Electric (24 V) or pneumatic actuation
- Break-glass and smoke-detector triggers
- Control panel with battery backup
- Replacement of failed or obsolete units
- Also usable for day-to-day ventilation
Before you order: points to check
- The product should be certified to BS EN 12101-2 as a natural smoke and heat exhaust ventilator
- Replacing a vent with a non-equivalent product can affect the fire strategy
Rules and responsibilities in Chadderton
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Smoke vent rooflights (AOVs) in Chadderton: questions
Can you replace an old smoke vent?
Yes, with an equivalent certified unit that matches the original design area and performance, so the fire strategy is not compromised.
Do you design the smoke strategy?
No — the strategy comes from the building's fire engineer or designer. We supply, install, commission and service to it.
Can a smoke vent be used for normal ventilation?
Many dual-purpose units also open for daily ventilation, closing automatically in rain.
Do I need to be at home for the survey in Chadderton?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Chadderton?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
