Abstract: Exterior wall system assemblies, exterior wall system component subassemblies, and exterior wall system components that incorporate drainage features and fireblocking features are disclosed. The drainage features can include a channel or conduit assembly by which moisture that collects within concealed spaces of the respective exterior wall system assembly can migrate via gravity from the concealed spaces out through the exterior wall system assembly, wall panel, or wall panel system to the outside of the building. The exterior wall system assemblies, exterior wall system component subassemblies, and exterior wall system components include fireblocking features that can inhibit the propagation of fire through the concealed spaces of the exterior wall system assembly.

Abstract: Prefabricated exterior wall panel systems that incorporate one or more drainage features are disclosed. The drainage feature can include a channel formed in the panel body in fluid communication with an interior portion of the panel body and an opening in the front face of the panel. The drainage feature also can include a wedge having a sloped surface thereon on which the channel can be aligned. The exterior wall panel systems having these drainage features can be used in the exterior cladding of buildings and other structures.
