Smoke vent rooflights (AOVs) in Rayleigh: what is involved?
For Rayleigh homes and buildings we offer smoke vent rooflights (AOVs): automatic smoke ventilators at the head of stairwells and atria. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Barn conversions and timber-framed homes across the East often call for conservation rooflights or bespoke glass. Smoke vent rooflights (AOVs) suit blocks of flats and commercial buildings with a smoke strategy.
Jobs in Rayleigh are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Specification options
- Electric (24 V) or pneumatic actuation
- Glazed rooflight or louvred vent
- Break-glass and smoke-detector triggers
- Rain and wind sensors for daily vent use
- Control panel with battery backup
- Glazed units bring daylight to stairwells
- Opens automatically on alarm signal
What to check first
- Smoke ventilation is designed to the building's fire strategy — we install to that design
- 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
Rules and responsibilities in Rayleigh
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. Fire classification of rooflight materials near boundaries is checked at specification.

Smoke vent rooflights (AOVs) in Rayleigh: 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.
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 Rayleigh?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Rayleigh?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
