Smoke vent rooflights (AOVs) for Barnes: the essentials
For Barnes 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.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. In Barnes, as anywhere, smoke vent rooflights (AOVs) are the usual choice for blocks of flats and commercial buildings with a smoke strategy.
We work across Greater London, including Barnes, and in neighbouring towns such as Chiswick and Putney. Access, parking and how the glass reaches the roof are all checked at the survey.
Choices for your Barnes project
- Glazed rooflight or louvred vent
- Control panel with battery backup
- Break-glass and smoke-detector triggers
- Electric (24 V) or pneumatic actuation
- Rain and wind sensors for daily vent use
- Manual override at the fire service access level
- Opens automatically on alarm signal
Before you order: points to check
- The product should be certified to BS EN 12101-2 as a natural smoke and heat exhaust ventilator
- Replacing a vent with a non-equivalent product can affect the fire strategy
Regulations for smoke vent rooflights (AOVs) in Barnes
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.
