Abstract: A panel system provides a prefabricated exterior building façade. Various wall claddings and clips for hanging wall claddings are discussed. Panel connector parts are disclosed for hanging wall cladding panels against a building wall. Panel connector parts are disclosed for hanging dual layers of insulating material against a building wall with a drainage cavity or gap defined between the dual layers. A wall cladding system includes: a building wall; a plurality of wall cladding panels each comprising insulating material and defining an external face, a rear face, and side edges, with adjacent of the wall cladding panels abutting one another along respective side edges; panel connector parts mounted on the building wall and mounting the plurality of wall cladding panels as a continuous thermal break layer against the building wall.

Abstract: A panel system provides a prefabricated exterior building façade. Various wall claddings and clips for hanging wall claddings are discussed. A wall cladding system includes: a building wall; a plurality of wall cladding planks; a plurality of fasteners extending through respective apertures in the plurality of wall cladding planks to secure the plurality of wall cladding planks to the building wall, in which each fastener has a head and a shaft, and the shaft mounts a spacer behind a rear face of the respective wall cladding plank to define a drainage gap between the wall cladding planks and the building wall. A wall cladding plank clip includes a fastener with a head and a shaft; a drainage gap spacer mounted on the shaft; and a front washer plate mounted on the shaft between the head and the drainage gap spacer.
