What do smoke vent rooflights (AOVs) in Kendal involve?
Smoke vent rooflights (AOVs) in Kendal means automatic smoke ventilators at the head of stairwells and atria. We cover the LA9 district and the rest of Cumbria, with a survey before any price is fixed.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. In Kendal, as anywhere, smoke vent rooflights (AOVs) are the usual choice for communal stairwells, corridors and atria.
Neighbouring towns include Ulverston (27 km) and Morecambe (30 km). We offer a survey date when we reply to your enquiry.

Things we check at survey

Building control and safety duties in Kendal
Smoke vents are life-safety equipment: in England the responsible person must keep them maintained under the Regulatory Reform (Fire Safety) Order 2005. We supply manufacturer-certified units and arrange installation, commissioning and servicing through specialist smoke-control engineers.
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.

Questions about smoke vent rooflights (AOVs) in Kendal
Can a smoke vent be used for normal ventilation?
Many dual-purpose units also open for daily ventilation, closing automatically in rain.
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.
Do I need to be at home for the survey in Kendal?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Kendal?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
