SUBSTANCE: invention relates to the field of construction, namely, to the method to manufacture floor boards, as well as floor board design. Semi-floating floor boards and/or construction panels are proposed, which have systems of mechanical connections, a core with curvilinear edge sections, as a result of which the surface layer on top of the core will be located below the panel surface. Edges of the board are slanted. As two boards are connected and pressed to each other, the surface layer and the core of the upper edge section at the second edge of the connection cover the surface layer, which is parallel to the horizontal plane of the first edge of connection of the other board. It is proposed to manufacture floor boards and/or construction panels by means of mechanical processing of the surface structure with production of multiple slots of the core and application of the surface layer on the upper side of the core to ensure at least partial cover of the floor element. Pressure is applied, and the surface layer is formed around the slots.
