Smoke vent rooflights (AOVs) in Derry/Londonderry: what is involved?
We handle smoke vent rooflights (AOVs) across County Londonderry, including Derry/Londonderry. In short: automatic smoke ventilators at the head of stairwells and atria. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Many Northern Irish homes have later flat-roofed kitchen extensions where an old dome can be swapped for glass. Think of smoke vent rooflights (AOVs) for blocks of flats and commercial buildings with a smoke strategy.
We cover all of Derry/Londonderry and the BT48 district, and nearby Strabane and Limavady.

Questions about smoke vent rooflights (AOVs) in Derry/Londonderry
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.
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.

No — the strategy comes from the building's fire engineer or designer. We supply, install, commission and service to it.
