Spacing profile for double-glazing unit
First Claim
1. A spacing profile for a spacing frame, which is to be fitted in the edge area of a double-glazing unit, forming an interspace, with a profile body of a material possessing low thermal conductivity, which incorporates contact flanges for contact with the insides of the panes of the double-glazing unit and a connecting flange bridging the interspace in installed state, by means of which at least two contact flanges are joined to one another, where the spacing profile additionally comprises a desiccant cavity, and further a metal foil, which extends essentially over the entire width of the spacing profile, where the metal foil is bonded to establish a material fit to cavity-side surfaces of the contact flanges, as well as to adjacent end sections of the connecting flange, characterized in that only the metal foil together with a center piece of the connecting flange forms the walls of the desiccant cavity.

Abstract
A spacing profile for a spacing frame, which is to be fitted in the edge area of a double-glazing unit, forming an interspace, with a profile body of a material possessing low thermal conductivity. The spacing profile additionally comprises a desiccant cavity, and further a metal foil, which extends essentially over the entire width of the spacing profile. Only the metal foil together with a center piece of the connecting flanges forms the walls of the desiccant cavity.
