A flexible sandwich panel (100), comprised of a center layer (1) and one or two outer layers (2; 3), where the center layer is made of a polymeric synthetic material, is itself flexible and exhibits a coarse-cell honeycomb structure with open cells (4) in the direction of the upper and lower side of the center layer. The outer layer or layers consist of a hardened mortar that is made flexible with synthetic additives, and that have as their core a web material consisting essentially of fibers, where the exterior side (5) of the hardened outer layer is left unrefined or roughcast in a plaster-like manner. The sandwich panel can be bent without flaking of the outer layers.
