How we approach smoke vent rooflights (AOVs) in Redruth
Our smoke vent rooflights (AOVs) service in Redruth covers automatic smoke ventilators at the head of stairwells and atria. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Stone cottages, slate roofs and conservation areas are common in the South West, and conservation-profile rooflights keep the roofline quiet. Smoke vent rooflights (AOVs) suit communal stairwells, corridors and atria.
We work across Cornwall, including Redruth, and in neighbouring towns such as Camborne and Truro. Access, parking and how the glass reaches the roof are all checked at the survey.

Building control and safety duties in Redruth
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.
Read the planning permission guide before you commit to a design.
