What do smoke vent rooflights (AOVs) in Weymouth involve?
For Weymouth homes and buildings we offer smoke vent rooflights (AOVs): automatic smoke ventilators at the head of stairwells and atria. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Holiday lets and second homes across the South West often want roof windows with blinds and remote opening for when the house is empty. In Weymouth, as anywhere, smoke vent rooflights (AOVs) are the usual choice for communal stairwells, corridors and atria.
Weymouth sits about 12 km from Dorchester and 25 km from Bridport, and we cover the whole DT4 postcode district and the roads in between.

Regulations for smoke vent rooflights (AOVs) in Weymouth
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.

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.
Do smoke vents need a control panel?
Electric AOVs work with a control panel that links them to detectors, the fire alarm and override switches.
Do I need to be at home for the survey in Weymouth?
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 Weymouth?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
