What do smoke vent rooflights (AOVs) in Thetford involve?
We handle smoke vent rooflights (AOVs) across Norfolk, including Thetford. 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.
Flat, open landscape in much of the East means roofs take the wind, so upstand and seal details matter more than the brand of glass. Typical uses for smoke vent rooflights (AOVs) include communal stairwells, corridors and atria.
Neighbouring towns include Bury St Edmunds (19 km) and Diss (25 km). We offer a survey date when we reply to your enquiry.

Smoke vent rooflights (AOVs) in Thetford: questions
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.
