The origins of rhombic shaped panel cladding systems for building facades can be traced to the middle of the 18th century. Initially all the items were produced and installed manually. Today, the elements are increasingly being produced by machine.
The appearance of the rhombic-clad facade system depends, among others, on the size and format of the cladding elements:
Here we distinguish between small rhombic tiles with sizes ranging to about 400 mm and large rhombic systems with edge lengths up to 1200 mm.
Nowadays, small cladding systems are predominantly used for applications in renovations and monumental protection. The large rhombic system is used mainly for modern facades to provide architectural design means.
Depending on the type of installation and the element size of the format, we distinguish between diamond shaped and square-/rectangular shaped rhombic tiles. The 180° turn-up that is applied to all four sides is typical for these shapes. In this case, forward-bendings are applied to two sides and the two opposite sides are provided with backward-bendings.
The rhombic elements are either assembled directly on the element or indirectly with so-called welt joints or fastening strips on the two bent sides.
The two backward-bends serve to hook into elements that have already been installed.
In line with sheet metal techniques, connections and terminations are frequently formed into flashings.
