A method of fastening a wall panel to a wall, according to one illustrative embodiment, comprises coupling a retaining body to a mounting body mounted on an outer surface of the wall adjacent a side edge of the wall panel. Coupling the retaining body to the mounting body may comprise coupling a first connector on an inner surface of the retaining body to a second connector on the mounting body, and positioning a retainer on the retaining body against a retaining surface on the wall panel to fasten the wall panel to the wall. Kits and wall assemblies according to other illustrative embodiments are also disclosed.

A corner trim mounting system includes a corner trim fastening bracket having a first arm and a second arm joined at an angle. Each arm includes a plurality of inward-facing outer teeth configured to couple the fastening bracket to a building substrate at an outer corner, and a plurality of outward-facing inner teeth configured to receive trim boards so as to retain the trim boards to form a corner trim. The two sets of inner teeth can be parallel such that the fastening bracket can be driven into two perpendicular trim boards simultaneously. A complementary pressing assembly, including a trim support and a bracket driver, may be provided to facilitate assembly of corner trim using the fastening bracket.

A rain-screen siding system for buildings, including clips to support siding boards parallel with a flat surface of a building wall structure but spaced apart from the building wall to allow air to circulate between the building wall structure and the siding boards. The clips include paired, opposed channels and the siding boards have tongues that fit into the channels. Drainage grooves are defined in the clips. Bottom support members may extend horizontally to support the siding boards at the bottom of the rain screen siding. Corner closing members are provided to protect end faces of siding boards at an exterior corner of a building wall.

The present application discloses a wall panel and corner construction system for installation onto a building structure, and methods for installing same.

A wallboard-fastening device secures first and second wallboards to a framing member without fasteners passing through the wallboards. The device includes first, second, and third framing panels joined along lengthwise edges to form a three-sided cup sized to fit around the framing member, first and second flat-spring flanges joined along lengthwise edges to form a front seam, and a channel-dividing panel joined lengthwise to the front seam and to the second framing panel to form first and second channels that receive the first and second wallboards. The flat-spring flanges flex to exert restoring forces on the wallboards that push the wallboards against the second framing panel. The device may be configured for edge joints, outside-corner joints, and inside-corners, and thus may be combined for any type of wallboard installation, including both parallel and perpendicular applications.
