A plasterboard panel fit for covering elements of any dimension and shape, provided with an anterior wall and a posterior wall covered by a related cardboard sheet, anterior (2) and posterior (3), has equidistanced parallel grooves (4) on the posterior wall of the panel fit to form linear sliding guides in correspondence with precise scorings made by means of a manual cutter, or with precise millings or cuts made by means of a miller or a portable electric saw, which have a support base provided with relieves fit to be inserted into the grooves (4). In a variant, the grooves (4) are made along two mutual perpendicular directions, in such a way to make a guiding grid (8). The panel is coupled with a grooved metal or plastic sheet (6) which is shaped for its joint insertion into the grooves (4) so making brackets for the dry linkage of the panel with the wall or with the adjacent panels.
