How we approach smoke vent rooflights (AOVs) in Portishead
We handle smoke vent rooflights (AOVs) across Somerset, including Portishead. In short: automatic smoke ventilators at the head of stairwells and atria. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Barn and chapel conversions in the South West often need bespoke or shaped rooflights to suit the original structure. Typical uses for smoke vent rooflights (AOVs) include blocks of flats and commercial buildings with a smoke strategy.
Jobs in Portishead 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.
What you can choose
- Glazed rooflight or louvred vent
- Rain and wind sensors for daily vent use
- Control panel with battery backup
- Break-glass and smoke-detector triggers
- Electric (24 V) or pneumatic actuation
- Also usable for day-to-day ventilation
- Servicing and testing available
What to check first
- Smoke ventilation is designed to the building's fire strategy — we install to that design
- Replacing a vent with a non-equivalent product can affect the fire strategy
Building control and safety duties in Portishead
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. Fire classification of rooflight materials near boundaries is checked at specification.
See our building regulations guide for U-values, glazing limits and self-certification.

Yes, with an equivalent certified unit that matches the original design area and performance, so the fire strategy is not compromised.

Electric AOVs work with a control panel that links them to detectors, the fire alarm and override switches.
