An edge bond bracket for an insulating glass unit extends in a longitudinal direction with a constant cross-section and includes an at least substantially U-shaped bracket body made of a material having a specific thermal conductivity less than or equal to 0.3 W/(mK). The bracket body includes at least one base, a first side wall and a second side wall. At least two troughs are defined in the base between the first side wall and the second side wall for accommodating adhesive and a pane. A gas impermeable diffusion barrier layer is formed integrally on and/or in the bracket body, extends continuously between two troughs starting from an inner wall of one of the two troughs and ending on an inner wall of the other of the two troughs, and extends either along an outer side of the U-shape of the bracket body or through the bracket body.
