An insulating panel assembly includes an exterior panel that is formed of a metal. The insulating panel assembly also includes an interior panel. A spacer is coupled to the exterior panel and the interior panel. The spacer maintains the exterior panel in a generally parallel, spaced relationship with the interior panel.

An interlocking panel system for covering a base surface with interlocking panels to prevent water ingress. A first panel is secured to the base surface. A second panel interlocks with the first panel via a hook portion on the second panel entering a receptacle of the first panel. The hook portion expands after entering a retaining portion of the receptacle, thereby preventing the hook portion of the second panel from being withdrawn from the first panel.

The present teachings relate to a solar roof forming element for forming a solar roof of a building, comprising an extruded, elongate polymer roof plate, element coupling means, at least one solar panel covering the roof plate, panel coupling means for coupling the solar panel to the roof plate, comprising a first coupling part at a first side of the roof plate and a second coupling part at a first side of the solar panel, said coupling parts configured such that they mutually couple as a result of a movement of the solar panel relative to the roof plate, wherein in a coupled state a movement of the solar panel away from the roof plate in a direction perpendicular to the roof plate is blocked. The present teachings further relate to a combination of such solar roof forming elements, to a building, and to a method of forming a roof.

A tufted geosynthetic lightweight ballast system for roof protection in which the system comprises a composite of one or more geotextiles tufted with one or more synthetic yarns.

A method of molding a building product may include providing an injection mold with a plurality of gates located adjacent a perimeter of the injection mold. The method may further include commingling a first material and a second material into a flow. The second material may be a color that contrasts with a color of the first material. The method may include injecting the commingled flow into the plurality of gates to form an injection molded building product, and removing the molded building product from the injection mold. In addition, the second material may extend through an interior of the molded building product and appear as contrasting streaks on an exterior of the building product to form a variegated grain appearance.

A cover apparatus (1), comprising cover plates (2) continuing in a position of use in a common plane and in at least one row, is formed in a mutual edge-side contact region (3) through overlapping and in a rainproof manner, such that edges (5) running parallel to each other and spaced apart on each cover plate (2) are designed differently (6), and the top side (7) of the cover plate (2), a continuing web (8) and a rain gutter (9) under said web (8) are arranged on a first edge (5), wherein said rain gutter belongs to the same first edge (5). If necessary, penetrating rain water (12) can be caught in the rain gutter (9) by overlapping edge-side webs (8) in the position of use.
