How we approach smoke vent rooflights (AOVs) in Devizes
Thinking about smoke vent rooflights (AOVs) in Devizes? 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.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Typical uses for smoke vent rooflights (AOVs) include communal stairwells, corridors and atria.
We work across Wiltshire, including Devizes, and in neighbouring towns such as Melksham and Chippenham. Access, parking and how the glass reaches the roof are all checked at the survey.
Choices for your Devizes project
- Rain and wind sensors for daily vent use
- Break-glass and smoke-detector triggers
- Control panel with battery backup
- Glazed rooflight or louvred vent
- Electric (24 V) or pneumatic actuation
- Manual override at the fire service access level
- Also usable for day-to-day ventilation
Things we check at survey
- 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
- Replacing a vent with a non-equivalent product can affect the fire strategy
Regulations for smoke vent rooflights (AOVs) in Devizes
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.

Common 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.
Can a smoke vent be used for normal ventilation?
Many dual-purpose units also open for daily ventilation, closing automatically in rain.
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.
