Smoke ventilation solutions
Aluminium AOV Windows
Modern buildings require safety systems that work actively, reliably and discreetly. Arkay manufactures high-performance Aluminium Automatic Opening Vent (AOV) Windows that support effective smoke ventilation while complementing contemporary architecture.
Built using the proven AluK 58BW HI aluminium window system, our AOV windows are suitable for residential developments, apartment buildings, schools, healthcare facilities, offices and commercial projects — for both new-build schemes and upgrades.
With more than 50 years of experience, Arkay works with architects, contractors, developers and installers across the UK.
What are Automatic Opening Vent windows?
AOV windows — also known as smoke vent windows — form part of a building’s smoke-control strategy. During a fire, smoke can reduce visibility and create hazardous conditions. When activated by a fire alarm or smoke-detection system, an AOV opens automatically to provide a defined aerodynamic free area for the natural exhaust of smoke and heat.
A correctly designed system can help to:
- Remove smoke from escape routes
- Improve visibility during evacuation
- Reduce temperatures
- Assist emergency services
- Protect building occupants
Arkay AOV windows are designed to integrate with wider fire-safety and smoke-ventilation systems.
Designed around the AluK 58BW HI system
The AluK 58BW HI is a thermally broken aluminium window system that combines contemporary appearance with dependable commercial performance.
Its slim profiles, strong weather performance, durability and thermal efficiency make it a versatile choice for modern developments. AOV configurations can be manufactured in multiple opening styles to suit the project design and certified parameters.
