The difference between lifting-sliding door systems, sliding doors, and parallel slide and tilt doors (PSK)

Lifting-sliding door system
Lifting-sliding door systems are opened by lifting them slightly and sliding them sideways, making them particularly space-saving as the sash does not swing into the room. When lifted, there is no friction between the sealants, frame, and sash, which means that even large and heavy sashes can b

Lifting-sliding door systems are opened by lifting them slightly and sliding them sideways, making them particularly space-saving as the sash does not swing into the room. When lifted, there is no friction between the sealants, frame, and sash, which means that even large and heavy sashes can be moved effortlessly. After lowering the sash onto the frame, the door is particularly tight and energy-efficient. Lifting-sliding door systems can be designed in a barrier-free or flush with the floor version with zero barriers. Thanks to optional motorization, even heavy sashes can be moved comfortably and quietly—ideal for open, light-flooded living spaces with continuous glass surfaces.

Sliding doors

Sliding doors are moved sideways without lifting the sash, which also saves space. They are simpler in constructional design and therefore more cost-effective than lifting-sliding door systems, but still provide unrestricted panoramic views. The fitting technology is less complex, making installation particularly efficient. However, the frictional resistance when opening and closing can be slightly higher. This variant can also be implemented with barrier freedom and a floor-level threshold.

Parallel slide and tilt doors (PSK)
Parallel sliding tilt doors combine two functions: they can be slid open sideways to allow access or tilted like a window to allow ventilation. Their compact construction makes them particularly suitable for smaller door openings on balconies or terraces. As the construction is based on a windo

Parallel sliding tilt doors combine two functions: they can be slid open sideways to allow access or tilted like a window to allow ventilation. Their compact construction makes them particularly suitable for smaller door openings on balconies or terraces. As the construction is based on a window system, PSK doors do not offer complete barrier freedom, but they score points for their versatility and attractive price-performance ratio.
