The Dual-Action Mechanism Advantage: Micro-Ventilation vs. Side Turn
Unlike standard American sliding or single-hung windows that rely on brush seals prone to friction wear, Tilt and Turn Windows engineered by Foshan Aluvoy Entry Door Systems Co., Ltd. incorporate continuous multi-point compression gearing. A single, ergonomically designed handle controls two distinct operational modes:
- The Inward Tilt Position (100mm-150mm top opening): Enables draft-free, security-conscious micro-ventilation. Rising warm air escapes through the top aperture while fresh air enters gently along the sides, preventing rain ingress even during stormy weather.
- The Full Inward Turn Position (90°–180° swing): Transforms the sash into a wide-opening side-hinged portal for maximum airflow, emergency egress compliance, and safe interior cleaning of exterior glass surfaces in mid-rise and high-rise structures.
This dual action provides an exceptional seal when closed. When the handle is turned to the lock position, mushroom locking cams drive firmly into perimeter frame keeps, compressing high-elasticity EPDM gaskets along three continuous sealing planes. This eliminates air infiltration and achieves structural water tightness ratings exceeding 900 Pa.
