Natural smoke and heat ventilation units that also provide natural light, comfort ventilation and roof access Automatic Opening Vent (AOV) Rooflights are electrically operated natural smoke and heat exhaust ventilators (NSHEV) that allow natural light into a building. They can also be used for comfort ventilation as well as roof access. Designed for easy installation on flat roofs up to 15°, the units open to 140° in less than 60 seconds. Designed, tested and CE-marked in accordance with BS EN 12101-2 Standard and bespoke sizes provide design flexibility to suit project requirements Variable kerb heights available for quick installation Thermally broken kerb reduces risk of condensation Dual-colour options available to match the external roofscape and internal décor VELUX Commercial AOV Rooflights are multipurpose units that are suitable for providing natural smoke and heat exhaust, as well as comfort ventilation and natural light. They can also be used to provide safe and easy access to a roof for inspection or maintenance requirements. The AOV is electrically operated and opens upon detection of smoke. It can also be fully controlled through the building management system, giving building users and managers peace of mind. AOVs can be fixed directly to the roof deck (with a minimum kerb height of 300mm, as the unit needs to be 300mm above the finished roof surface). Adapter kerbs are available for fixing to an upstand (with a minimum base kerb height of 300mm). The AOV kerb and lifting frame is fabricated from aluminium, which can be insulated and thermally broken for use above a heated space.
