How we approach smoke vent rooflights (AOVs) in Hull
For Hull homes and buildings we offer smoke vent rooflights (AOVs): automatic smoke ventilators at the head of stairwells and atria. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Many Yorkshire homes have had kitchen extensions with flat roofs, where a larger glass rooflight is a straightforward upgrade from an old dome. In Hull, as anywhere, smoke vent rooflights (AOVs) are the usual choice for blocks of flats and commercial buildings with a smoke strategy.
Hull is the main town we list in the East Riding of Yorkshire; we also cover nearby Beverley and Hornsea.
Specification options
- Glazed rooflight or louvred vent
- Rain and wind sensors for daily vent use
- Control panel with battery backup
- Electric (24 V) or pneumatic actuation
- Break-glass and smoke-detector triggers
- Also usable for day-to-day ventilation
- Servicing and testing available
What to check first
- 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
Building control and safety duties in Hull
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. Fire classification of rooflight materials near boundaries is checked at specification.
Read the planning permission guide before you commit to a design.
