The 3D decorative panel is a piece of material, usually straight and cut into a rectangular shape, serving as a visible and exposed wall cover. 3D panels are functional as well as decorative, provide isolation and sound isolation, combine with uniformity of appearance, with a certain durability or ease of replaceability. Although there is no limit on the size of a piece of material that fulfills these functions, the maximum practical size for wall panels is suggested to be 40x40cm to facilitate easier transportation.

Using 3D wall panels can reduce construction costs by ensuring a consistent appearance of tiled surfaces without the need for applying paint or other finishing materials. 3D panels can only be finished on one side if the other side is against masonry brick or concrete or similar structures. Alternatively, panels may, if mounted on the appropriate box, be replaced by any other type of wall at all. The notches can be cut or bent on the panel to accommodate electrical sockets and other devices coming from the wall.
