PRODUCT COVERING

Abstract

The invention relates to an impregnated material with a base (o) and a decorative layer on top (7), wherein the base (6) is of thermoplastic composition, arbitrarily filled, wherein the impregnated material (1) is made on at least the first pair of opposite edges (2'3) having a mechanical coupling device (15) allowing two such materials (1) to fit together on the first pair of edges under consideration (2-3), wherein the locking is achieved both in the vertical direction (VI) perpendicular to the plane of the coupling centers (1), and in the horizontal direction (Hl) perpendicular to the corresponding edges (2-3) and in the plane of the coupling materials (1), differing in that the mechanical coupling device (15) or coupling parts allow movement in the direction along the coupling edges, and wherein, on the second pair of opposite edges, the contact surface and / or locking acting in the horizontal direction (23) is made, preferably directly at the location where the surfaces The top surfaces of the joint plates (1) press against each other, and in this contact surface (23) is formed mainly, and preferably uniquely,on the compressible portion of the subbase and / or sublayer.
