PSK
The PSK tilt-and-slide system is most often used in private house construction. It is one of the most popular systems in Ukraine and is usually fitted as an exterior door to a balcony or terrace. The sash tilts for ventilation and is operated by hand. The room can also be aired by sliding the sash partly to the side. An extended, specially designed ergonomic handle makes the system exceptionally quiet and smooth to operate. Even a child can use it.

The Roto Patio Aversa KS system has a standard Roto NT central locking mechanism and standard Roto window handles. It has a modern design and hinge covers in 4 colours: white, brown, silver and gold. Roto Patio Aversa KS has a mechanism that automatically pulls the sash into the opening from the open and tilted positions. Because the sash moves to the side, it saves a considerable amount of room space. The system is well protected against moisture and draughts thanks to seals around the entire sash perimeter.
The maximum sash weight is 160 kg. Up to 3.5 metres with one sliding sash, and up to 7 metres with two central sliding sashes.
