What do smoke vent rooflights (AOVs) in Maldon involve?
Thinking about smoke vent rooflights (AOVs) in Maldon? 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.
In the East of England, bungalows and chalet bungalows with large flat-roofed extensions are common, and they often suit a long run of rooflights. Think of smoke vent rooflights (AOVs) for blocks of flats and commercial buildings with a smoke strategy.
From Maldon to Witham, Chelmsford and Rayleigh, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Break-glass and smoke-detector triggers
- Glazed rooflight or louvred vent
- Rain and wind sensors for daily vent use
- Electric (24 V) or pneumatic actuation
- Control panel with battery backup
- Opens automatically on alarm signal
- Glazed units bring daylight to stairwells
What to check first
- 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 Maldon
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.
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.
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 a smoke vent be used for normal ventilation?
Many dual-purpose units also open for daily ventilation, closing automatically in rain.
Can you work alongside my builder in Maldon?
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 Maldon?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
