DrehKipp

DrehKipp refers to a window hardware concept used in German-speaking markets to describe a sash that can be operated in two modes: Dreh (turn) and Kipp (tilt). The term is commonly associated with Dreh-Kipp-Beschläge, a type of multi-point hardware installed on the sides of the window frame that combines a hinge with a tilt latch and locking mechanism.

In the Dreh position the sash can swing inward or outward, providing nearly full opening for ventilation or cleaning access. In the Kipp position the sash tilts inward from the top, allowing controlled ventilation while maintaining a secure, partially closed state. A centralized handle and the integrated locking system secure the sash in both modes. Many designs also include anti-lift devices, additional safety features, and weather-sealing gaskets to improve performance in varying conditions.

The DrehKipp system is commonly used on modern PVC, wood, and aluminum windows and is installed by manufacturers as a standard component of tilt-and-turn window construction. It enables flexible operation without the need for separate hardware components and is compatible with a range of frame profiles and sealing systems. Because the concept is widely adopted across European markets, it is closely tied to the broader class of tilt-and-turn windows, which emphasize ease of cleaning, versatile ventilation, and enhanced security.
