The unique tilt - in function of tilt - and - turn windows has advantages that other window types can't match.
1. Optimize ventilation performance
When the window is tilted inwards, the room can be naturally ventilated. More importantly, the air enters the room from the upper and side parts of the window and doesn't directly blow onto people's bodies. Especially when the temperature difference between the indoor and outdoor is large, it can greatly reduce the risk of people catching a cold due to direct wind blowing.

2. Improve security
When the window is tilted inwards, the window is in an open and ventilated state. At the same time, compared with out - swinging or in - swinging casement windows, it is very safe and has anti - theft properties.
3. Dust - proof and rain - proof properties
When the window is tilted inwards, the air flow entering the room will first be blocked by the glass. Heavier dust particles in the air are less likely to make "sharp turns" and are naturally blocked outside.
4. Easy to clean.
5. Suitable for installing outdoor shading products
Germany pays special attention to the energy - saving of doors and windows. Therefore, there must be shading products outside the windows to prevent excessive exposure to the sun and save the cooling energy consumption of air conditioners.
