Tilt & Turn System
Inspired by European performance glazing systems, the SiON Tilt & Turn Window System combines intelligent functionality with refined architectural design. Engineered for modern residential and commercial applications, the system offers two distinct opening modes within a single window — a secure inward tilt for controlled ventilation, and a full inward opening for maximum airflow, cleaning access, and usability.
Slim aluminium profiles create clean architectural lines while delivering exceptional structural strength, durability, and long-term weather resistance.
Every component is manufactured to exacting standards to ensure seamless functionality, refined movement, and long-term performance.
Engineered from high-performance components, the SiON hardware system is designed for durability, smooth operation, and reliable everyday use.
The advanced tilt hinge mechanism enables secure inward tilting of the sash, providing controlled ventilation without fully opening the window.
Integrated stay hardware securely limits the tilt opening distance, improving safety, ventilation control, and stability during operation.
Precision-adjustable hinge hardware allows for accurate vertical alignment, ensuring smooth operation and perfect sash positioning during installation and over the lifespan of the system.
Fine horizontal adjustment capability allows for precise sash alignment, improving sealing performance, operational smoothness, and installation accuracy.
The tilt position allows fresh air circulation while maintaining security and protection from harsh weather conditions, creating a comfortable and controlled indoor environment.
A single intuitive handle controls the three operating modes locked, tilt ventilation, and full turn opening allowing effortless functionality and user control.
Heavy-duty turn hinge hardware supports smooth inward opening while maintaining exceptional structural stability and long-term reliability.
