Abstract: An assembly includes elongated foamed elements that are arranged next to one another in one plane and bonded to one another at abutting side faces thereof, wherein the elongated foamed elements have been made by cutting at least one foamed sheet having a top and bottom surface, the at least one foamed sheet having been prepared by a foamed extrusion process and comprises a polymer composition including polypropylene, wherein the cutting is perpendicular to the top and bottom surfaces of the at least one foamed sheet, wherein the assembly has a top and bottom surface formed of surfaces of the elongated foamed elements perpendicular to the top or bottom surface of one of the at least one foamed sheet from which the respective elongated foamed element has been made, wherein the assembly is a sheet having a compression stress at yield in the thickness direction of at least 100 kPa.
