How we approach smoke vent rooflights (AOVs) in Ormskirk
Thinking about smoke vent rooflights (AOVs) in Ormskirk? 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. Smoke vent rooflights (AOVs) suit communal stairwells, corridors and atria.
Neighbouring towns include Maghull (7 km) and Skelmersdale (7 km). We offer a survey date when we reply to your enquiry.

Before you order: points to check
- 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
Building control and safety duties in Ormskirk
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.
