Abstract: A cladding apparatus includes a receiving member securing an insulation member, and a forming member having a delivery portion and a base. A cladding surface of the base is spaced from a coatable surface of the insulation member to define a cavity. A conduit of the delivery portion delivers a coating material, through a coating aperture in the base, into the cavity. The cladding surface forms a composite cladded insulation piece, including a coating layer bonded to the coatable surface. An inner coating surface of the coating layer has projections securely encasing the coated surface of the insulation member. A mounting surface of the insulation member is mounted on a building substrate. A wall finish is applied to an outer surface of the coating layer. Corresponding methods of forming and installing the pieces are also provided.
