Abstract: A multi-layer structure of the tile or slat type is for the realization of a floor covering having acoustic insulation properties. The structure includes, in this order, a decorative layer, a first rigid layer made of PVC, a first damping layer made of PVC, and a second rigid layer made of PVC. The first and second rigid layers each have an elasticity modulus of between 1.5 GPa and 12 GPa, measured according to standard ISO 178:2011.
