Patent ID: 7757455

Claim:
A spacer frame arrangement for insulating glass units, comprising: a spacer profile body extending in a first direction and having a predetermined cross section in a plane perpendicular to the first direction, the predetermined cross section being constant along the first direction defining a hollow inner space of the spacer profile body with predetermined dimensions in the plane perpendicular to the first direction, and a connector comprising a connector section adapted to be inserted in the first direction into the hollow inner space of the spacer profile body by having a cross sectional shape perpendicular to the first direction which corresponds, with predetermined tolerances, to a cross sectional shape of the hollow inner space, at least the outer surface of the connector section facing the inner surface of the hollow inner space of the spacer profile body after insertion of the same, and the inner surface, being made of a material fusable by melting the same, wherein the connector section is inserted into the hollow inner space of the spacer profile body and the outer surface of the connector section and the inner surface of the spacer profile body facing each other are at least partly connected by mutually melt fusing the outer surface of the connector section with the inner surface of the spacer profile body.
