What do smoke vent rooflights (AOVs) involve?
Smoke vent rooflights (AOVs) in Wiltshire means automatic smoke ventilators at the head of stairwells and atria. Every quote follows a survey of the roof and the room below.
Barn and chapel conversions in the South West often need bespoke or shaped rooflights to suit the original structure. Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs.

Planning and building rules in England
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.

Common questions
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.
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 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.
How often should AOVs be tested?
Industry guidance recommends regular functional checks and at least annual servicing. Your fire risk assessment sets the regime.
Do you fit smoke vent rooflights (AOVs) across Wiltshire?
Yes. We survey and fit smoke vent rooflights (AOVs) across Wiltshire, including Swindon, Salisbury, Trowbridge.
