A water impervious wall panel system includes an intermediate first wall panel composed of a waterproof core and a decorative surfacing attached to the core, wherein the intermediate first wall panel is provided with tongue-and-groove edges. The water impervious wall panel system also includes an end second wall panel composed of a waterproof core and a decorative surfacing attached to the core, wherein the end second wall panel is provided with a tongue-and-groove edge and a rolled edge. One of the tongue-and-groove edges of the intermediate first wall panel and the tongue-and-groove edge of the end second wall panel form an interlocking system having a contact area adjacent to a front face of the intermediate first wall panel and the end second wall panel and a gap adjacent a rear face of the intermediate first wall panel and the end second wall panel, the contact area surface extending across less than the thickness of the intermediate first wall panel and the end second wall panel so as to provide a tight joint at the front face and eliminate visible gaps.

A system for mounting a facade and an insulation body to a structure utilizing a base member that includes a first portion attached to the structure. The base member includes a platform for supporting the insulation body and a flange extending outwardly from the platform. The flange includes attachment mechanisms for holding a panel or frame to form a facade.

A composite siding panel mountable on an exterior wall of a building includes a backing member and a siding member attached to the backing member, wherein the first side edge of the siding member overhangs the first side edge of the backing member, and the second side edge of the siding member also overhangs the second front side edge of the backing member. An adhesive coating joins the front face of the backing member to the rear face of the siding member. The adhesive coating runs substantially from the first side edge of the backing member to the second side edge thereof. In the field, the overhang on one side can be trimmed or removed as desired to make a siding assembly with the overhangs organized as desired for aesthetic purposes. A siding assembly including a plurality of composite siding panels adjacently mountable on an exterior wall of a building is also disclosed.

A pre-finished insulated panel system for cladding an exterior wall of a building, the system comprising: rectangular panels each with an insulation core and weather resistant coating defining a central portion with a panel thickness between an inside mounting surface and an exposed outside surface, the plurality of panels adapted for engagement in a series of parallel rows; each panel having: a mounting flange disposed on the top edge and on a first lateral edge of each panel, the mounting flange including: a recessed mounting groove; an inner ridge; and an outer ridge; an elongate cover flange complementary with the mounting flange disposed on the bottom edge and on an opposing second lateral edge, the cover flange including: an inner groove complementary to the inner ridge; and an outer groove complementary to the outer ridge; and mechanical fasteners within the recessed mounting groove and anchoring to the wall.

A thermoplastic composite sheet for exterior cladding applications includes an outer layer with a thermoplastic resin composition reinforced with a high aspect ratio filler such that the outer layer has a coefficient of linear thermal expansion of no more than approximately 2.3310.sup.5 in/in/deg F., and a backing layer bonded to the outer layer, the backing layer defined by a foam material. The outer layer and the backing later define a body having a substantially planar outer surface.

One aspect of the disclosure is a siding panel having a front face, a rear face, a top edge, a bottom edge, a first side, and a second side, the top edge being folded over to create two layers of material. The siding panel further includes a first locking mechanism disposed on the front face adjacent the top edge configured to interlock with a second locking mechanism of a second siding panel, the first locking mechanism having a generally S-shaped portion. The siding panel also includes a second locking mechanism disposed on the rear face of the siding panel having a generally U-shaped portion including a curved section, and the second locking mechanism being configured to interlock with a first locking mechanism of a third siding panel. The first locking mechanism and the second locking mechanism facilitate both locking and unlocking of the siding panel from the third siding panel.

A water impervious wall panel system includes an intermediate first wall panel composed of a waterproof core and a decorative surfacing attached to the core, wherein the intermediate first wall panel is provided with tongue-and-groove edges. The water impervious wall panel system also includes an end second wall panel composed of a waterproof core and a decorative surfacing attached to the core, wherein the end second wall panel is provided with a tongue-and-groove edge and a rolled edge. One of the tongue-and-groove edges of the intermediate first wall panel and the tongue-and-groove edge of the end second wall panel form an interlocking system having a contact area adjacent to a front face of the intermediate first wall panel and the end second wall panel and a gap adjacent a rear face of the intermediate first wall panel and the end second wall panel, the contact area surface extending across less than the thickness of the intermediate first wall panel and the end second wall panel so as to provide a tight joint at the front face and eliminate visible gaps.

A siding panel assembly includes a thermoplastic siding panel and a foam backing panel that is adhered to the thermoplastic siding panel. The siding panel assembly has a coefficient or linear thermal expansion of no more than about 2.0410.sup.5 (in/in/deg F.) and a planar (e.g., flat) outward facing surface.

A siding assembly includes a siding panel and an insulating panel securable to a wall using a siding attachment member. The siding attachment member includes openings extending therethrough in equally spaced relationship that align with slots formed in the foam panel. The spacing between centers of the foam panel slots corresponds to the spacing between centers of the openings in the attachment member. The slots in the foam panels are sufficiently wide to allow the foam panel to slide relative to the fasteners securing the foam panel to a wall. The siding attachment member may comprise a bracket with legs projecting rearward from a web and a siding support shoulder formed at a lower end of the web. Lines of weakness in the web and aligned notches in the shoulder facilitate cutting the bracket to a desired length. Reinforcement ribs are formed in the bracket web.
