Embodiments relate to a plastic wall panel, comprising a hollow body having external walls and defining an internal cavity. The external walls include: a first major side wall, a second major side wall opposite the first major side wall, a minor top wall, a minor bottom wall, a first minor end wall and a second minor end wall opposite the first minor end wall. The minor top wall and the minor bottom wall each define mating structure to mate and align with another adjacent panel so that multiple panels can be tiled together to form at least part of a sound attenuation barrier. The hollow body defines a passage extending between the first and second major side walls and through the first and second minor end walls to receive a reinforcing beam.
Some embodiments relate to a moulded cladding panel. The panel may comprise: a hollow plastic body formed by rotational moulding, the body having a length, a width and a depth, a first end, an opposite second end, an upper section, an opposite lower section, a first major face defined by a front wall extending from the first end to the second end and from the upper section to the lower section, and a second major face defined by a back wall opposite the first major face, the second major face extending from the first end to the second end and from the upper section to the lower section. The upper section defines a plurality of first mounting formations to facilitate mounting of the panel to a structure to be clad. The lower section defines a plurality of second mounting formations to facilitate mounting the panel to the structure.

A hollow plastic wall panel, the panel having a length greater than a width, a thickness less than the width, a front wall, an opposite back wall and opposed first and second long edge regions, wherein the panel comprises a first end and a longitudinally opposite second end, wherein the first long edge region defines at least one first recessed portion to longitudinally receive and mate with a first longitudinal support structure and wherein the second long edge region defines at least one second recessed portion to longitudinally receive and mate with a second longitudinal support structure.
E04C 2/22 - Building elements of relatively thin form for the construction of parts of buildings, e.g. sheet materials, slabs, or panels characterised by specified materials of wood, fibres, chips, vegetable stems, or the likeBuilding elements of relatively thin form for the construction of parts of buildings, e.g. sheet materials, slabs, or panels characterised by specified materials of plasticsBuilding elements of relatively thin form for the construction of parts of buildings, e.g. sheet materials, slabs, or panels characterised by specified materials of foamed products of plastics reinforced
E04H 17/16 - Fences constructed of rigid elements, e.g. with additional wire fillings or with posts using prefabricated panel-like elements, e.g. wired frames
Described embodiments relate generally to plastic wall panels. Described wall panels are formed by rotational moulding processes and may be used in sound attenuation barriers or other wall or building structures. Some embodiments include reinforcing structure. The reinforcing structure may be configured to effectively support a plastic shell of the wall panel in a way that allows some relative movement between the plastic shell and the reinforcing structure.
