At Quantum Windows, we supply high performing AOVs to trade glazing installers across the Midlands. Electrically operated, AOVs help to regulate heat and natural smoke via an effective ventilation system. AOV roof lights are also an effective way to boost natural light in a building interior. Where required, they can also function as a means of roof access and are a popular choice for installations in flat roofs. Our AOVs are fully certified to BS EN 12101-2 and are available in both uPVC and aluminium.
