Component which comprises two parallel, flat wire mesh mats (M1, M2) made from longitudinal and transverse wires (L1, L2; Q1, Q2) which cross one another and are welded to one another at the crossing points, straight frame wires (V1, V2) which hold the wire mesh mats at a predefined, mutual spacing and are connected at each end to the two wire mesh mats, and a central element which is arranged between the wire mesh mats and at a predefine spacing parallel to the latter and is formed from a dimensionally stable, thin barrier layer (T) which is penetrated by the frame wires and is held by the latter at a predefined spacing from each of the wire mesh mats. |
