What do smoke vent rooflights (AOVs) in Preston involve?
Thinking about smoke vent rooflights (AOVs) in Preston? 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.
Exposed hillside towns in the North West need flashing and seal details that cope with wind-driven rain. Typical uses for smoke vent rooflights (AOVs) include communal stairwells, corridors and atria.
We cover all of Preston and the PR1 district, and nearby Leyland and Chorley.

Common questions
Do you design the smoke strategy?
No — the strategy comes from the building's fire engineer or designer. We supply, install, commission and service to it.
Can you replace an old smoke vent?
Yes, with an equivalent certified unit that matches the original design area and performance, so the fire strategy is not compromised.
Can a smoke vent be used for normal ventilation?
Many dual-purpose units also open for daily ventilation, closing automatically in rain.
