Sonarol PSK PVC Patio Door System

Sonarol PSK PVC Tilt-and-Slide Patio Door System

The Sonarol PSK PVC Patio Door System combines tilt ventilation with a sliding opening in a single patio-door mechanism. When closed, the moving sash sits in the same plane as the adjacent sash; to open it, the hardware first tilts the sash back and then guides it onto the running track. Sonarol describes the fixtures as operable with one hand, linking a controlled ventilation position with a larger sliding passage. Stays hold the sash in its tilted position when ajar, while the carriage guides the moving leaf during travel. This makes PSK a practical choice where a patio door should provide both a venting position and a way to move the sash aside without a conventional inward swing. Sonarol lists three PVC profile bases for PSK doors: Clasictherm, Optitherm and Perfectherm. The maximum published sash weight is 200 kg. Those profile names and the sash limit describe system options and capacity; glazing, profile depth and the complete door performance follow the selected build. Manufacturer system and reference data depend on the selected profile base, glazing and finished PSK configuration.

Tilt ventilation and guided sliding travel

The PSK movement has two distinct stages. For ventilation, the sash tilts away from the frame and stays keep it held in that position. For a full opening, the sash is moved onto its running track and travels sideways, leaving the doorway available without the leaf swinging through the room. This sequence is the defining feature of a tilt-and-slide patio door and separates everyday airing from passage through the opening. Sonarol’s description notes additional push-back control on fixtures for large and heavy sashes; the mechanism assists with pressing the sash shut during closing and supports the opening action. Running carriages guide the sash along its track, while the profile base establishes the frame and sash construction around the selected glass. Clasictherm, Optitherm and Perfectherm are the named PVC bases available for the Sonarol PSK system. Each offers a path for building the frame and leaf, with the final panel layout and glazing specified for the actual door. The published 200 kg maximum sash weight is a reference for the product type, not a statement of the assembled unit’s total mass. In daily use, the appeal of PSK is its combined function: a tilted ventilation position when the room needs fresh air, and a guided sliding movement when occupants want to pass through to a patio, balcony or garden. The same handle-led fixture sequence connects these two uses, so the sash moves from its closed plane into the vent position or onto the track as needed.
