What do smoke vent rooflights (AOVs) in Nottingham involve?
Thinking about smoke vent rooflights (AOVs) in Nottingham? 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.
Many Midlands semis have had a single-storey rear extension added, and a larger flat rooflight or lantern is often the change that makes it feel finished. Typical uses for smoke vent rooflights (AOVs) include communal stairwells, corridors and atria.
We cover all of Nottingham and the NG1 district, and nearby West Bridgford and Arnold.

Rules and responsibilities in Nottingham
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. Fragile-roof safety and access are planned before work starts.
