What do smoke vent rooflights (AOVs) in Castlereagh involve?
We handle smoke vent rooflights (AOVs) across County Down, including Castlereagh. 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.
Northern Ireland has a mix of terraces, bungalows and rural farmhouses, and rooflights are a common upgrade when extending. Typical uses for smoke vent rooflights (AOVs) include communal stairwells, corridors and atria.

Building control and safety duties in Castlereagh
Smoke vents are life-safety equipment: in Northern Ireland the appropriate person must keep them maintained under the Fire and Rescue Services (Northern Ireland) Order 2006 and the Fire Safety Regulations (Northern Ireland) 2010. We install to the building's fire strategy and the manufacturer's certification.
For non-domestic buildings in Northern Ireland, Technical Booklet F2 covers energy performance; we supply the manufacturer's data for building control. Fragile-roof safety and access are planned before work starts.
