Night ventilation for Lift&Slide doors: open but still securely locked
With the night ventilation for Lift&Slide doors, Gretsch-Unitas has successfully developed an innovative solution, as the RC 2-tested night ventilation allows the sliding sash to be put in the ventilation position but also provides effective burglar resistance by locking the sliding sash securely to the frame in this position.
- Outstanding ventilation convenience paired with high degree of burglar protection (RC 2 tested)
- Securely locked even in ventilation position
- Integrated into frame and therefore concealed when closed
- Simple operation
- Integrated insect screen
