Abstract: A cladding system for cladding a supporting structure, the cladding system includes two cladding panels each defining a respective substantially laterally extending panel flange. The cladding panels are attachable to the supporting structure in a substantially coplanar and side-by-side relationship relatively to each other. The system also includes a cladding moulding insertable between the first and second cladding panel, the cladding moulding defining a moulding base and two moulding legs each extending from the moulding base substantially opposed to each other, the two moulding legs being angled relatively to the moulding base, each of the moulding legs defining a respective leg edge substantially opposed to the moulding base. The cladding moulding being substantially resiliently deformable between an undeformed configuration and a deformed configuration, the moulding legs being spaced apart from each other by a smaller distance in the deformed configuration than in the undeformed configuration.
