What do smoke vent rooflights (AOVs) in Carmarthen involve?
Our smoke vent rooflights (AOVs) service in Carmarthen covers automatic smoke ventilators at the head of stairwells and atria. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. Smoke vent rooflights (AOVs) suit communal stairwells, corridors and atria.
Carmarthen sits about 22 km from Llanelli and 23 km from Ammanford, and we cover the whole SA31 postcode district and the roads in between.

- Replacing a vent with a non-equivalent product can affect the fire strategy
Rules and responsibilities in Carmarthen
Smoke vents are life-safety equipment: in Wales the responsible person must keep them maintained under the Regulatory Reform (Fire Safety) Order 2005 (as it applies in Wales). We install to the building's fire strategy and the manufacturer's certification.
For non-domestic buildings in Wales, Approved Document L sets limiting U-values for rooflights and roof ventilators; we supply the manufacturer's data for the building control submission. Fragile-roof safety and access are planned before work starts.
Read the planning permission guide before you commit to a design.

Common 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 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 work alongside my builder in Carmarthen?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Carmarthen?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
