A flexible inside corner trim piece is formed with concave depressions at hinge portions where wings attach to the body. The trim piece can be formed such that wings and a top cap lay flat in plane perpendicular to body or wings and top cap curve at an angle. Hinge portions can be narrow or wide and symmetrical or asymmetrical. The trim piece can be dyed, paintable, or present another decorative surface. The trim piece can include embedded lighting.

The present invention provides a wall paneling system that is completely mechanical and does not require the use of adhesives in attaching panels to the walls. The system comprises wall panels having a core with a decorative surface attached to one side and profiled edges that connect to each other by push click, panel connector clips (PCCs) that further connect and secure the interconnecting panels to the walls; and corner moldings for use in paneling adjoining walls meeting at a corner via tongue and groove. The PCCs and corner moldings attach to the walls by mechanical fastening and provide an air space between the walls and the wall panels. Since the wall panels are not directly connected or adhered to the wall, the system allows the panels to be easily replaced by removing and inserting from the PCCs and corner moldings. By using specially adapted bottom seals, seals in the corner moldings and sealant between the panels, the paneling system can be made impermeable to water and is therefore especially useful in area wet areas such as bathrooms.

A construction element is provided for forming a corner of a surface of a building, the surface including wall panels attached to framing studs. The construction element includes: a corner-forming surface that that is shaped to extend, in a cross-sectional view, between two separate wall panels, such that ends of the corner-forming surface, as viewed in the cross-sectional view, substantially match respective corners of the wall panels. The construction element may be provided in multiple sections that are placed end to end and connected together.

A wallboard-fastening device for securing first and second wallboards to a framing member in an outside-corner configuration includes: first and second framing panels that connect to each other to form an inner corner seam that fits against the framing member; first and second corner panels that connect to each other to form an outer corner seam; a first bridge panel that connects to (i) the first corner panel to form a first outer seam and (ii) the inner corner seam; a second bridge panel that connects to (i) the second corner panel to form a second outer seam and (ii) the inner corner seam; a first flat-spring flange that connects to the first outer seam to form a first channel sized to accept the first wallboard; and a second flat-spring flange that connects to the second outer seam to form a second channel sized to accept the second wallboard.

There is disclosed an improved wall panel trim reveal system and method which utilizes a set of vertical, horizontal and corner trim pieces designed to be fitted together. In an embodiment, the system includes horizontal trim pieces having at least one slope, vertical trim pieces having at least one tab forming a slot for receiving one or more horizontal trim pieces therein, wherein the horizontal and vertical trim pieces when installed together with wall panels forming a moisture drainage channel to direct moisture away from the wall.

A wall panel base trim a panel channel extending between first and second ends. The panel channel surrounds a panel groove configured for reception of a wall panel therein. The panel channel includes a blending fin extending from the channel base, the blending fin on a second side of the panel groove. A brace ridge extends between the first and second ends, the brace ridge projects laterally relative to the panel channel. A shadow flange extends away from the panel channel in a second direction, the shadow flange and the brace ridge cooperate to form a shadow line recess.

An inside corner backer board molding insert is provided. The molding insert includes a body formed by a rigid member. An arcuate portion disposed on a front side of the body extends longitudinally from an upper face to a lower face of the body. The arcuate portion defines a concave surface extending laterally from a first longitudinal edge to a second longitudinal edge. A pair of laterally extending walls extend perpendicularly relative to each other and intersect forming a corner edge disposed on a rear side of the body. The corner edge forms a right angle sized to engage an inside corner of a wall. Opposing sides of the body interconnect the arcuate portion to the laterally extending walls and include a width sized to receive a backer board flush thereagainst. A lip extending outwardly from and edge of the opposing sides provides a support surface for the backer board.

A trim piece for sealing a work surface including a body having a first side, a second side, and a span disposed between the first side and the second side, wherein the first side and the second side are joined at a junction defining an angle between the first side and the second side of between 80 degrees and 100 degrees, a topcap is affixed to the span of the body, wherein the topcap includes a left side having a first wing and a right side having a second wing, an adhesive is bonded to the first side of the body and an aperture is disposed within the body.

A cladding kit is provided for a structure cladding, the structure cladding comprising a first panel that extends away from a structure location along a first surface portion of the structure and a second panel that extends away from the structure location along a second surface portion of the structure. The cladding kit comprises a base piece couplable to the structure at the structure location, the base piece comprising a base connector, and a trim piece comprising first and second wings and a trim connector shaped to make a connection with the base connector to thereby couple the trim piece to the base piece. The first wing is shaped to contact, and be deformed by, the first panel when a connection is made. The second wing is shaped to contact, and be deformed by, the second panel when the connection is made.

A system for mounting wall panels to an existing wall, includes fastening extrusions, each including an extrusion base section adapted to be secured to the existing wall, at least one retaining wall extending at an angle from the base section, and a holding member on each retaining wall; and intermediary supports for supporting the wall panels at a position between side edges of the wall panels, each intermediary support including an intermediary support base plate adapted to be secured to the existing wall, and a sliding member adapted to be slidably connected with the base plate, such that one wall panel is adapted to be secured on the sliding member for sliding movement relative to the intermediary support base plate with the sliding member in order to slide a side edge of the wall panel into one fastening extrusion between the extrusion base section and the holding member.
