What do smoke vent rooflights (AOVs) in Marlborough involve?
Smoke vent rooflights (AOVs) in Marlborough means automatic smoke ventilators at the head of stairwells and atria. We cover the SN8 district and the rest of Wiltshire, with a survey before any price is fixed.
Holiday lets and second homes across the South West often want roof windows with blinds and remote opening for when the house is empty. In Marlborough, as anywhere, smoke vent rooflights (AOVs) are the usual choice for blocks of flats and commercial buildings with a smoke strategy.
Jobs in Marlborough 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.

Building control and safety duties in Marlborough
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.
See our building regulations guide for U-values, glazing limits and self-certification.
