ABSTRACT:
A closing element for rooms, such as buildings, containers, superstructures of vehicles or the like, which can be rolled up and covers a two-dimensional area. The closing element is of a flexible material which can be rolled up and is reinforced transversely of its rolling direction by bending-resistant reinforcement layers which increase the transverse stiffness and which are embedded on both sides of a core zone within the closing element. At least the core zone of the closing element is of a shifting-resistant material of middle-soft formulation of approximately 70-85 shore A, and/or textile and/or metal flakes or fibers are mixed into the material of the core zone.
