Osnova manufactures modern sliding systems equipped with Winkhaus primePort SK-S, SK-Z and PAS hardware. Different opening options make it possible to select a solution according to the dimensions of the construction, sash weight, ventilation method and requirements for operating comfort. primePort systems are suitable for PVC and aluminium constructions and are particularly well suited for balcony and terrace solutions.

Sliding Systems with Winkhaus primePort SK-S Hardware

Winkhaus primePort SK-S is a hardware solution for tilt-and-slide systems, combining convenient sliding operation with the option of tilting the sash for ventilation.

The system is operated using a single handle: turning the handle by 90° switches the sash to sliding mode, while turning it by 180° activates the tilt position. The mechanism ensures smooth movement and intuitive operation. Depending on the version, primePort SK-S is designed for sash weights of up to 100 or 160 kg.

Sliding Systems with Winkhaus primePort SK-Z Hardware

Winkhaus primePort SK-Z is tilt-and-slide hardware designed for large and heavy sashes, providing comfortable operation via the handle.

A key feature of SK-Z is its assisted operation: when the handle is turned by 180°, the mechanism automatically moves the sash from the closed position into the tilt position. This makes large constructions easier to operate and reduces the risk of incorrect handling. The system is available in versions for sash weights of up to 160 and 220 kg. Depending on the opening configuration, burglary-resistant versions up to RC2 class are also possible.

Sliding Systems with Winkhaus primePort PAS Hardware

Winkhaus primePort PAS is sliding hardware with a parallel displacement function, designed to provide comfortable and efficient room ventilation.

In ventilation mode, the sash moves approximately 6 mm away from the frame around its entire perimeter, allowing a gradual supply of fresh air without fully opening the construction. When required, the sash can be switched to full sliding mode to open the passage.

Osnova manufactures sliding systems equipped with Winkhaus primePort PAS hardware - a practical solution for residential and commercial premises where comfortable ventilation, ease of operation and efficient use of interior space are important.
