Smoke vent rooflights (AOVs) in Amersham: what is involved?
Thinking about smoke vent rooflights (AOVs) in Amersham? 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.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. In Amersham, as anywhere, smoke vent rooflights (AOVs) are the usual choice for communal stairwells, corridors and atria.
We work across Buckinghamshire, including Amersham, and in neighbouring towns such as Chesham and Chalfont St Peter. Access, parking and how the glass reaches the roof are all checked at the survey.
Choices for your Amersham project
- Rain and wind sensors for daily vent use
- Electric (24 V) or pneumatic actuation
- Glazed rooflight or louvred vent
- Control panel with battery backup
- Break-glass and smoke-detector triggers
- Glazed units bring daylight to stairwells
- Also usable for day-to-day ventilation
What to check first
- Smoke ventilation is designed to the building's fire strategy — we install to that design
- 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
Rules and responsibilities in Amersham
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.
