What do smoke vent rooflights (AOVs) in Swindon involve?
Our smoke vent rooflights (AOVs) service in Swindon 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.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Typical uses for smoke vent rooflights (AOVs) include communal stairwells, corridors and atria.
We cover all of Swindon and the SN1 district, and nearby Marlborough and Cirencester.

Before you order: points to check
- Smoke ventilation is designed to the building's fire strategy — we install to that design

Regulations for smoke vent rooflights (AOVs) in Swindon
Smoke vents are life-safety equipment: in England the responsible person must keep them maintained under the Regulatory Reform (Fire Safety) Order 2005. We install to the building's fire strategy and the manufacturer's certification.
For buildings other than dwellings, Approved Document L Volume 2 sets limiting U-values of 2.2 W/m²K for rooflights and 3.0 W/m²K for roof ventilators, including smoke vents. Fire classification of rooflight materials near boundaries is checked at specification.
See our building regulations guide for U-values, glazing limits and self-certification.
