Smoke vent rooflights (AOVs) in Dagenham: what is involved?
Thinking about smoke vent rooflights (AOVs) in Dagenham? 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. Typical uses for smoke vent rooflights (AOVs) include blocks of flats and commercial buildings with a smoke strategy.
From Dagenham to Romford, Hornchurch and Barking, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Break-glass and smoke-detector triggers
- Service and test plans
- Rain and wind sensors for daily vent use
- Electric (24 V) or pneumatic actuation
- Glazed rooflight or louvred vent
- Also usable for day-to-day ventilation
- Manual override at the fire service access level
What to check first
- 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 Dagenham
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.
See our building regulations guide for U-values, glazing limits and self-certification.
