Multi-layer floor covering

摘要

A multi-layer floor covering made up of inseparably joined together: secondarily foamed polyurethane foam (1), insulation foil (2), thermal insulation (3) and a hardened layer (6). An upper layer (7) is fastened to the upper surface of the hardened layer (6) through one of the wider surfaces of the upper layer (7) being spread with binding material (8) which also covers both surfaces of a membrane (9) in such a way that one side of the binding material is adhered to the bottom surface of the upper layer (7), while on the other, external side of the membrane, binding material is adhered to the upper surface of the hardened layer (6).
