How we approach smoke vent rooflights (AOVs) in Edmonton
Thinking about smoke vent rooflights (AOVs) in Edmonton? 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 London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Smoke vent rooflights (AOVs) suit blocks of flats and commercial buildings with a smoke strategy.
Edmonton sits about 3 km from Tottenham and 3 km from Enfield, and we cover the whole N18 postcode district and the roads in between.
What you can choose
- Service and test plans
- Electric (24 V) or pneumatic actuation

Things we check at survey
- Whoever holds the building's fire-safety duties (the responsible person, the duty holder in Scotland or the appropriate person in Northern Ireland) must keep systems maintained and tested
- The product should be certified to BS EN 12101-2 as a natural smoke and heat exhaust ventilator
Rules and responsibilities in Edmonton
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.
