What do smoke vent rooflights (AOVs) in Farnworth involve?
Thinking about smoke vent rooflights (AOVs) in Farnworth? 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.
Exposed hillside towns in the North West need flashing and seal details that cope with wind-driven rain. Smoke vent rooflights (AOVs) suit blocks of flats and commercial buildings with a smoke strategy.
Neighbouring towns include Walkden (4 km) and Bolton (4 km). We offer a survey date when we reply to your enquiry.

Rules and responsibilities in Farnworth
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.

Questions about smoke vent rooflights (AOVs) in Farnworth
Who is responsible for maintaining smoke vents?
The responsible person (or duty holder in Scotland, appropriate person in Northern Ireland) for the building must keep fire safety systems maintained. We can arrange servicing and keep records.
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 smoke vents need a control panel?
Electric AOVs work with a control panel that links them to detectors, the fire alarm and override switches.
Do I need to be at home for the survey in Farnworth?
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 Farnworth?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
