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
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.
