What do smoke vent rooflights (AOVs) in Harlow involve?
Our smoke vent rooflights (AOVs) service in Harlow 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.
Many homes in the East have low-pitched roofs on later extensions, which are better served by flat rooflights than pitched roof windows. Think of smoke vent rooflights (AOVs) for communal stairwells, corridors and atria.
Harlow is around 49 km from Southend-on-Sea, and we survey and fit throughout that part of Essex, including the CM17 district.

Before you order: points to check

- Smoke ventilation is designed to the building's fire strategy — we install to that design
Regulations for smoke vent rooflights (AOVs) in Harlow
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.
