Abstract:
1. A cladding panel comprising: at least two pairs of side edges lying substantially opposite one another; a coupling mechanism structured and arranged on at least one of the at least two pairs of side edges, and comprising a groove and a tongue extending along respective side edges of the at least one pair; and a roughening formed on at least a section of the tongue and on at least a section of the groove, wherein the roughening comprises a toothing extending in a tooth sequence running direction that is essentially in the longitudinal direction of the respective side edge and in a tooth extension direction that is essentially in a circumferential direction of the groove and the tongue such that a longitudinal axis of each individual tooth extends essentially in the circumferential direction, whereby the at least one roughening section of the tongue and the at least one roughening section of the groove are arranged to form complementary sections that bear against one another when the cladding panel is connected to at least one other cladding panel, wherein the roughening formed on the at least one section of the tongue is formed on a protrusion, and wherein the roughening formed on the at least one section of the groove is formed on a corresponding recess, wherein the roughening increases friction between the groove of a first panel and the tongue of a second panel.
