Flexa SL 45 partition wall
Flexibility and variation options for dividing interiors, from offices and libraries to schools and restaurants
The SL 45 Flexa partition wall system lives up to its name: it stands out for its high flexibility and numerous opening variants. One section of the panel opens inwards, the other outwards, and even segmented ground plans are possible.
Slim panel profiles and large glass areas allow daylight into every part of the room, even when the partition is closed. Accessible floor tracks guarantee a seamless transition from one part of the room to another, and the panels can be adjusted after installation, with the height set up to 8 mm to compensate for structural tolerances.
The system suits all areas where organisational or functional separation, or connection, of indoor spaces is required while retaining flexibility. Special gears with a 24 mm latch bolt lock the panels into the top and bottom frame profiles, and profile cylinders are available for additional security.
