A spacer section with backing layer
2010
A spacer section for use as a spacer frame of a Isolierfenstereinheit, with a profile body made of a plastic material, having an inner wall, an outer wall and laterally in the transverse direction of the side walls, thus defining a chamber for receiving hygroscopic material, a diffusion barrier layer of a first metal material having a first tensile strength and a first thickness which is formed at least on or in the outer wall and at least a portion of the side walls, and a reinforcing layer, characterized in that the reinforcing layer of a second metal material having a second tensile strength and a second thickness in the inner wall or on the chamber facing side of the inner wall is formed and the product of the second thickness and the second tensile strength is greater than the product of the first thickness and the first tensile strength or characterized in that the reinforcing layer of a second metal material having a third modulus of elasticity that is greater than the second modulus of elasticity, and is formed of a second thickness on the inner wall or on the side facing the chamber side of the inner wall and the product of the second thickness and the third elasticity modulus is greater than the product from the first thickness and the second modulus of elasticity.
