Support element for interlocking wall covering. It is the element that must be fixed to the lower structure (wall, attic, wall, etc.), and then attached to the wall covering through the lateral joints. This way the upper wall covering will not be punctured and will be able to expand as desired. Furthermore, and most importantly, this system ignores the irregularities of the lower wall. By then placing the first and last brackets, and connecting them through a line that will mark the levels of the remaining brackets, we will obtain a perfectly straight wall covering.
