Abstract: An expandable panel, constructed such that the expandable panel can at least expand in at least one direction, includes a panel having a front face and rear face bordered by side edges, end edges and a thickness dimension extending between the front and rear faces and includes discretely spaced cuts extending from the front face to the rear face or rear to front face. The cuts form bridging members between living hinges and are elongate and extend in a spaced longitudinal manner including at least one cut forming a side of the expandable panel located on one side of the cut, and at least two cuts located on a side of the expandable panel. The at least one cut on side and the other cuts on side together forming at least one pair of lines being substantially parallel, offset mirror images of each other and being intermeshed but not touching.

Abstract: A connector for connecting a panel member to an overhead support structure or cross support member includes an elongate planar body with a first planar surface and second planar surface separated by a thickness dimension, having side edges and end edges. Each end portion includes an enlarged partially rounded shape. The first end portion is a fixing portion and the second end portion is a locating portion. The fixing portion includes a fixing unit to removably affix one connector to the panel capping member, overhead support structure or cross support member. The fixing portion includes a first camming body extending outwardly, having a base portion extending from the first end portion, leading to a platform portion forming at least one recessed gap for locating the camming surfaces. The fixing portion includes a further fixing unit to affix the connector to the overhead support structure or panel capping member.
