What do smoke vent rooflights (AOVs) in Braintree involve?
Our smoke vent rooflights (AOVs) service in Braintree 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.
Coastal towns in the East of England see salty air, so we specify frame finishes and fixings with exposure in mind. Think of smoke vent rooflights (AOVs) for communal stairwells, corridors and atria.
Jobs in Braintree are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
What you can choose
- Electric (24 V) or pneumatic actuation
- Rain and wind sensors for daily vent use
- Service and test plans
- Break-glass and smoke-detector triggers
- Glazed rooflight or louvred vent
- Manual override at the fire service access level
- Glazed units bring daylight to stairwells
Before you order: points to check
- The product should be certified to BS EN 12101-2 as a natural smoke and heat exhaust ventilator
- 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
Regulations for smoke vent rooflights (AOVs) in Braintree
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. Fire classification of rooflight materials near boundaries is checked at specification.
See our building regulations guide for U-values, glazing limits and self-certification.
