The new PSK Comfort generation goes beyond being a systematic development of the PSK modular concept; it offers a completely new equipment concept. This makes both operation and installation extremely easy. For example, depending on the weight of the sash, innovative comfort components can flexibly and efficiently meet customer-specific needs and provide solutions that meet even the highest standards.

For different users to be able to use the product easily, even at first touch, the system needs to work both intuitively and safely.
With PORTAL PSK Comfort, ease of use begins at the manufacturing stage. The intelligent comfort components are extremely easy to assemble; thus, maximum user comfort is achieved efficiently and effectively.
A quieter, more stable movement experience.
The specially coated guide rail, working in harmony with the robust carrier rail, ensures smooth and balanced movement of the sash.
Thanks to its self-supporting design, no additional support profiles are needed for sash weights up to 160 kg. This simplifies the system and significantly eases the assembly process.


The PORTAL PSK rollers, featuring up to 25% larger diameter, ensure a smoother and more comfortable sliding experience. For sash weights up to 160 kg, the carrier rail generally does not require an additional support profile. Thanks to the 125 mm frame-sash spacing provided by the large rollers, the system can be used with deeper and more highly insulated profiles, offering enhanced flexibility in design.
Key Advantages:
This design combines ease of operation, structural reliability, and installation flexibility in a single compact solution.
