Cladding system.

A cladding board mountable to an underlying structure, the cladding board comprising:

• a board body defining longitudinally opposed board body first and second ends, board body first and second sides extending therebetween and opposed inside and outside surfaces each delimited by the board body first and second ends and first and second sides, the outside surface being visible when the cladding boards have been laid;
• an outside flange protruding from the board body at the board body first side, the outside flange being recessed relative to the inside surface;
• an inside flange protruding from the board body at the board body second side, the inside flange being recessed relative to the outside surface;
• wherein the inside and outside flanges are configured and sized so that the inside flange of the cladding board overlaps the outside flange of a similar cladding board when the two cladding boards are laid side-by-side with their outside surfaces substantially coplanar.

A cladding system mounted to an underlying structure, comprising:

• a plurality of elongated cladding boards, each cladding board including
• a board body defining longitudinally opposed board body first and second ends, board body first and second sides extending therebetween and opposed inside and outside surfaces each delimited by the board body first and second ends and first and second sides, the outside surface being visible when the cladding boards have been operatively mounted to the underlying structure;
• an outside flange protruding from the board body at the board body first side, the outside flange being recessed relative to the inside surface;
• an inside flange protruding from the board body at the board body second side, the inside flange being recessed relative to the outside surface;
• wherein the cladding boards are mounted side-by side with the their outside surfaces substantially coplanar and the outside flange of each of the cladding board overlapping the inside flange of an adjacent one of the cladding boards.
