Joint between the ends of prefabricated spacers for insulating glass, and process for producing said joint

Abstract

A diffusion-tight joint (30) between ends of prefabricated spacers (10) that support a diffusion barrier (3) on the spacer outer face is achieved in that a tongue (9) is formed from the diffusion barrier (3) at an end of two spacers (10) that abut each other at a joint (30), the tongue protruding over the end. The tongue (9) is fixed to the outer face of the diffusion barrier (3) of the other end of the spacer (10) using an adhesive application (13) so that an overlapping of the diffusion barriers (3) of both ends is achieved. The formation of the joint can be formed in the corner region of prefabricated spacer frames (10) or in straight regions of spacers (10), thus wherever ends of spacers (10) that are prefabricated abut each other.
