Abstract:
1. A spacer profile for use as a spacer frame of an insulating window unit, the spacer profile comprising: a profile body made of a synthetic material, which extends in a longitudinal direction (Z) and has a first width in a lateral direction (X), which is perpendicular to the longitudinal direction (Z), and a first height in a height direction (Y), which is perpendicular to the longitudinal direction (Z) and to the lateral direction (X), and the profile body has an inner wall in the height direction (Y), which is, in an assembled state of the insulating window unit, directed towards an intervening space between two panes of the insulating window unit, and has an outer wall on the opposite side of the inner wall and sidewalls laterally in the lateral direction so that a chamber for accommodating hygroscopic material is defined, a diffusion barrier layer made of a first metallic material having a first tensile strength and a first thickness the diffusion barrier layer being formed at least on or in the outer wall and at least partly on or in the sidewalls and a reinforcement sheet made of a second metallic material having a second tensile strength and a second thickness the reinforcement sheet being formed in the inner wall or on the side of the inner wall that is directed towards the chamber and wherein 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.
