Smoke vent rooflights (AOVs) in Melksham: what is involved?
Thinking about smoke vent rooflights (AOVs) in Melksham? 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.
Stone cottages, slate roofs and conservation areas are common in the South West, and conservation-profile rooflights keep the roofline quiet. Think of smoke vent rooflights (AOVs) for blocks of flats and commercial buildings with a smoke strategy.
Neighbouring towns include Trowbridge (8 km) and Chippenham (10 km). We offer a survey date when we reply to your enquiry.

Regulations for smoke vent rooflights (AOVs) in Melksham
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.

Common questions
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.
Can you work alongside my builder in Melksham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Melksham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
