CORTIZO, the international market leader in aluminum and plastic systems for architecture, is further expanding the capabilities of its COR VISION and COR VISION EVOLUTION sliding systems. With a new concealed track solution, the Spanish multinational is responding to the growing demand for minimalist design and the smoothest possible transition between indoors and outdoors.
With this new solution, the bottom frame can be completely concealed and integrated into a variety of floor finishes, such as wood, natural stone, and ceramic. This creates a virtually seamless transition between indoor and outdoor spaces, with the floor and sliding system forming a single visual unit.


The hidden track complements the minimalist design of COR VISION and COR VISION EVOLUTION. Both sliding systems are designed to allow in as much natural light as possible while keeping the visible aluminum face widths to a minimum. For example, the systems feature a slim mullion measuring 20 and 25 mm, respectively. In addition, there are solutions that align with current architectural trends. The pocket solution, for instance, allows the sliding panels to disappear completely into the wall. Corner configurations at 90° without a corner mullion are also possible, ensuring that corner openings remain completely free of visual obstructions.

The minimalist design is also consistently applied to the operating mechanism. In both systems, the side profile of the sash can be completely concealed within the frame. In COR VISION, this is achieved through a mullion design featuring a recessed locking mechanism. COR VISION EVOLUTION features a side lock, which opens the window with a gentle, semicircular twisting motion.
