How we approach smoke vent rooflights (AOVs) in Bodmin
Thinking about smoke vent rooflights (AOVs) in Bodmin? 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.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Typical uses for smoke vent rooflights (AOVs) include communal stairwells, corridors and atria.
We work across Cornwall, including Bodmin, and in neighbouring towns such as St Austell and Newquay. Access, parking and how the glass reaches the roof are all checked at the survey.

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
Regulations for smoke vent rooflights (AOVs) in Bodmin
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. Fragile-roof safety and access are planned before work starts.
Read the planning permission guide before you commit to a design.

The responsible person (or duty holder in Scotland, appropriate person in Northern Ireland) for the building must keep fire safety systems maintained. We can arrange servicing and keep records.
