A bracket assembly comprising a bracket member, and a backer. The bracket member comprises a plurality of fibers contained within a resin matrix. The at least one bracket member includes a body wall and at least one end wall oriented one of oblique and perpendicular to the body wall along at a first end thereof. The bracket member defines a bracket member stiffness. The backer is positioned over a portion of at least one of an inner surface and an outer surface of the at least one end wall. The backer comprises a metal member, and the backer defining a backer stiffness. The bracket member stiffness is between two and twenty times greater than the backer stiffness.

A system and a method are provided for securing an element (50) to a support surface (70). The system comprises at least one rail member (10), a mounting part (20) and the element. The rail member comprises a lower face (11) at least partially contacting the support surface, opposed to an upper face (12) and connected thereto by opposed lateral walls (14, 15) thereby to define a box section. Each lateral wall projects above the upper surface and an edge portion thereof forms an inward flange to define a substantially C-profiled rail with the upper surface. The mounting part (20) comprises a base plate, is substantially rectangular, made at least partially of a resilient material and dimensioned complementarily with the rail member, such that a width of the base plate corresponds at least to a distance intermediate the opposed lateral walls and a thickness of the base plate corresponds at least to a distance intermediate the upper face of the rail member and an underside of the flange, the at least partial resiliency of the base plate causing the mounting part to compress for sliding between the opposed rails and to decompress for achieving an interference fit. The base plate of the mounting part (20) comprises a topside (22) bearing at least a pair of upward feet (26A, 26B), each foot being configured on a same face with at least one tenon projecting orthogonally thereto. The or each element (50) has a lower face configured with at least two recesses (56A, 56B), each recess comprising a groove dimensioned for engagement with the or each tenon of a respective foot in use.

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.

Method for making a wall with the aid of drywall panels (1, 1a, 1b) and a background (2, 12, 25), wherein the drywall panels are provided with edge coupling profiles (3, 4, 6, 13, 14, 16) on their edges, which are arranged to be secured to the background and, subsequently, coupled to each other. The drywall panels may also be provided with a rear coupling profile (24). The drywall panels can be hooked together or coupled to each other by means of transverse sliding. The edge coupling profiles may also comprise anti-adhesive extensions (31), forming anti-adhesive edge areas (32) at the front side of the drywall panel on which stucco mass does not adhere. The measures according to the invention are intended to provide drywall panels which, after use, can be disassembled easily and cleanly so that the drywall panels can be reused as drywall panels, resulting in that the environment is not burdened with gypsum waste caused by damaged, broken and destroyed drywall panels.

A double return panel system utilizing a perimeter extrusion having an arm terminating in an end portion configured to contact and twice bend a panel. The panel fits into a slot formed adjacent the arm. The perimeter extrusion is held to a facade by a base member.

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.

In one of the embodiments of the disclosed system, the sliding support member may be comprised of the U-shaped plate that is separate from a forward extending support member, which further contains parallel capture walls. The U-shaped plate and the forward extending support member are then joined together using a dovetail joint, or another type of lock-and-key joint. The groove for such a joint is oriented at an angle, preferably a right angle to the direction of the slide of the sliding support member along the length of the base member. This embodiment of the sliding support member permits a mounting of the adjustable support member at an angle, preferably a right angle to the direction of travel of the sliding support member.
