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.

Spacing profile for double-glazing unit

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 and with a diffusion-impermeable metal foil which is bonded to the profile body so as to establish a material fit, is characterized in that the metal foil is, at least on the surface facing away from the profile body, provided with a corrosion preventing coating which comprises a colored lacquer coating and/or a layer of chromium or of a chromium alloy, wherein the corrosion preventing coating comprises a thickness which is lower by at least a factor of 2.5, preferably by at least a factor of 10 and further preferred by at least a factor of 20, as compared to the thickness of the metal foil.

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 material possessing low thermal conductivity and a metal layer, which is bonded to establish a form fit with the locating walls of the profile body intended for contact with the insides of the panes, wherein in each of the locating walls of the profile body a recess is provided, in which is arranged the metal layer, so that the contact surface formed by the profile body and the contact surface formed by the metal layer lie essentially in one plane.
