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 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.
