What do smoke vent rooflights (AOVs) in Llanelli involve?
Our smoke vent rooflights (AOVs) service in Llanelli 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.
Slate roofs, stone cottages and terraced valleys are typical across Wales, and slim rooflights that sit low in the slates suit them best. Think of smoke vent rooflights (AOVs) for blocks of flats and commercial buildings with a smoke strategy.
We cover all of Llanelli and the SA15 district, and nearby Gorseinon and Swansea.
What you can choose
- Glazed rooflight or louvred vent
- Control panel with battery backup
- Rain and wind sensors for daily vent use
- Break-glass and smoke-detector triggers
- Electric (24 V) or pneumatic actuation
- Manual override at the fire service access level
- Opens automatically on alarm signal
What to check first
- Smoke ventilation is designed to the building's fire strategy — we install to that design
- Replacing a vent with a non-equivalent product can affect the fire strategy
Rules and responsibilities in Llanelli
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. Fire classification of rooflight materials near boundaries is checked at specification.
See our building regulations guide for U-values, glazing limits and self-certification.
