Embodiments of the invention relate to clips for mounting on a support rail or sub-girt (such as an FRP sub-girt) and wall system assemblies that include such clips. An embodiment of the clip includes a first arm portion, a second arm portion, a connecting ledge connecting the first arm portion to the second arm portion, and a retaining arm portion connected to the second arm portion such that a retention cavity is defined between the retaining arm portion and the second arm portion. The clip may be mounted on a sub-girt at a mounting location such that a flange of the sub-girt resides in the retention cavity of the clip and such that the connecting ledge of the clip seats on a support surface of the sub-girt. When so mounted, the second arm portion of the clip covers the entirety of the outer surface of the flange and the retaining arm portion of the clip covers at least a portion of the inner surface of the flange such that both the second arm portion and the retaining arm portion are available-along with the sub-girt flange-to receive a fastener. When so mounted, the first arm portion of the clip is available to help retain an insulation layer in a wall system assembly.

A structure of two sections of particle board each having a top surface respectively, constructed of a laminate sheet of a material such as plastic or polycarbonate affixed to the top surface of the two sections. The two sections each having an end portion mounted to the free ends of the two sections.

The invention is related to an attachment system comprising one or more panels provided with pairs of mutually parallel grooves through the back surface of the panels, a plurality of support profiles and a plurality of support brackets. The support profiles comprise a portion having an L-shaped section comprising a first leg portion and a second leg portion, so that the support profiles may be attached vertically to a wall with the second leg portion oriented at a distance from the wall and parallel thereto. The support brackets are formed of a first and second bracket profile configured to be assembled by inserting respective leg portions of the bracket profiles into the grooves, and securing wall portions of the bracket profiles to each other, thereby assembling the bracket and simultaneously clamping the bracket in said grooves.
