Glazed unit comprising a profiled bead with a foaming agent and a bonded cover piece as well as the method for manufacturing the glazed unit

A glazed unit comprising:

• a glazed element producing a separation between an exterior space and an interior space, and including a profiled bead having, seen in cross-section, a base which is located in contact with a face of said glazed element and which has a thickness of at least 5 mm from said face, said base of the profiled bead including a material incorporating a foaming agent,
• wherein the thickness of the base is higher than a thickness of a remainder of said profiled bead and the foaming agent forms bubbles in the base such that the base is of a lower density than the remainder of said profiled bead, and
• a cover piece including a cover baseplate extending substantially parallel to said base and further toward an exterior than said base,
• an adhesive layer adhering said cover piece adhering to the exterior face of the base of said profiled bead, the adhesive layer being sandwiched between an interior face of said cover baseplate and the exterior face of said base;
• wherein said base has a density between 10% and 35% lower than the density of than the remainder of said profiled bead, and
• wherein said cover piece is attached only by said adhesive layer with no other attachment therefor and at least 100 N in pulling force is required to pull and detach said cover piece from said base.
