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 is characterized in that only the metal foil together with a centre piece of the connecting flanges forms the walls of the desiccant cavity, or the metal foil together with a centre piece of the connecting flange forms the walls of the desiccant cavity, where at least one of the walls of the desiccant cavity formed by the metal foil is provided with a reinforcing layer of a material possessing low thermal conductivity, whose thickness is a maximum of 50 % of the thickness of the connecting flange. In a third aspect a spacing profile for a spacing frame which is to be fitted in the edge area of a double-glassing unit, forming an interspace, with a profile body of a plastic material possessing low thermal conductivity and with a diffusion-impermeable metal foil which is bonded to the profile body so as to form a material fit, is characterized in that at least for parts of the profile body adjoining the metal foil, a plastic material with a bending modulus of elasticity (according to Din 53 457) of less than 1.900 N/mm2, preferably of loss than 1.500 N/mm2 and of at least 900 N/mm2 is used.
