Kybos is the line of mobile partition and false ceilings for controlled contamination environments. The partition structure is composed of modular self-supporting sandwich panels with a retractable system thickness of 45 and 62 mm. Panels and all the rounded connecting elements meet high standards of tightness, planarity, mechanical resistance to impact, resistance to chemical agents and reaction to fire, with low emission of fumes. The prefabricated partitions can be integrated with plasterboard or masonry walls and the assembly is carried out so as to ensure the continuity of the surfaces. The modularityand the possibility to differentiate the surface finishesof the panels, allow to create partition that adapt to the specificities of the environments.
