    摘要: A composite polystyrene profile extending longitudinally from a first end to a second end and comprising a front surface and a back surface, comprising
    a. a core portion comprising a polystyrene monopolymer foam extending in the longitudinal direction, the core portion comprising polystyrene foam with a density of the range of 160kg/m 3 to 240kg/m 3 ; and
    b. a skin portion or layer comprising/consisting of a (high impact) polystyrene copolymer and surrounding the core portion at least in the longitudinal direction, with a density in the range of 700kg/m 3 to 1300kg/m 3 ; wherein
    - the polystyrene profile comprises a combined density within the range of 200 to 360 kg/m 3 ; and
    - the skin portion comprises a non-uniform thickness in a transversal direction perpendicular to the longitudinal direction;

    and associated method of manufacturing these profiles.
