Fuente: WIPO "circular economy" A wall cladding system is disclosed in which cladding planks are reversibly mounted on Ω-shaped support rails by slot-fit hooks providing gravitational retention. Each hook includes anti-rotation and locking features cooperating with the support rail to prevent involuntary disengagement under wind and vibration. The system allows controlled thermal expansion through elongated compensation openings and enables selective removal of individual planks through a defined sequence of sliding, rotation and withdrawal movements, preventing involuntary disengagement under wind and vibration. The system provides secure retention without rigid fastening while allowing easy installation and maintenance.
