An insulating glazing unit including at least two glass sheets separated by, e.g., a gas-filled cavity. An insert serves for spacing the at least two glass sheets apart and has an internal face facing the gas-filled cavity and an opposed external face, together with a mechanism for sealing the inside of the glazing unit. The insert is in the form of a substantially flat profiled strip that girds the perimeter of the glazing unit by its internal face being pressed against the edges of the at least two glass sheets and held fast by a fastening device.

The invention claimed is: 1. Insulating glazing unit comprising: at least two glass sheets separated by a gas-filled cavity; an insert serving for spacing the at least two glass sheets and having an internal face facing the gas-filled cavity and an opposed external face, said insert having a linear buckling strength of at least 400 N/rn, said insert extending to outermost edges of the glass sheets without extending past the outermost edges of the glass sheets; and a sealing element configured to seal an inside of the insulating glazing unit, wherein the insert is in a form of a substantially flat profiled strip that girds a perimeter of the insulating glazing unit by its internal face being pressed against edges of the at least two glass sheets and held fast by a fastener, the insulating glazing unit does not include a spacer contacting facing surfaces of the glass sheets, and the insulating glazing unit does not include a metal coating contacting a facing surface of either of the glass sheets. 2. Insulating glazing unit according to claim 1, wherein the insert seals against gases, dust, and liquid water. 3. Insulating glazing unit according to claim 1, wherein the sealing element is placed at least on the external face of the insert. 4. Insulating glazing unit according to claim 3, wherein the sealing element includes a metal coating. 5. Insulating glazing unit according to claim 1, wherein the insert is entirely metallic. 6. Insulating glazing unit according to claim 3, wherein the insert includes a thermoplastic. 7. Insulating glazing unit according to claim 3, wherein the insert is based on a thermoplastic and reinforcing fibers. 8. Insulating glazing unit according to claim 7, wherein the reinforcing fibers are continuous or chopped glass fibers. 9. Insulating glazing unit according to claim 7, wherein the insert has a thickness of at least 0.25 mm. 10. Insulating glazing unit according to claim 3, wherein the insert includes stainless steel and has a thickness of at least 0.10 mm. 11. Insulating glazing unit according to claim 3, wherein the insert includes aluminum and has a thickness of at least 0.15 mm. 12. Insulating glazing unit according to claim 4, wherein the metal coating has a thickness of between 2 and 50 μm. 13. Insulating glazing unit according to claim 3, wherein the fastener is impermeable to water vapor and to gases. 14. Insulating glazing unit according to claim 3, wherein the fastener includes an adhesive. 15. Insulating glazing unit according to claim 14, wherein the adhesive has a tear strength of at least 0.45 MPa. 16. Insulating glazing unit according to claim 3, wherein the insert has first and second free ends joined together to gird the entire insulating glazing unit so that the first free end overlaps the second free end, and complementary sealing elements are provided to seal off lateral portions left open by the overlap. 17. Insulating glazing unit according to claim 3, wherein the insert has first and second free ends that have complementary shapes configured to fit together to produce an abutment to gird the entire insulating glazing unit. 18. Insulating glazing unit according to claim 17, wherein an adhesive tape, or adhesive, impermeable to gases and to water vapor, is applied to a region of the abutment. 19. Insulating glazing unit according to claim 3, having a complex shape, particularly with curved parts. 20. Insulating glazing unit according to claim 1, wherein said insert is arranged entirely outwardly of the edges of the at least two glass sheets. 21. Insulating glazing unit comprising: at least two glass sheets separated by a gas-filled cavity; an insert serving for spacing the at least two glass sheets and having an internal face facing the gas-filled cavity and an opposed external face, said insert having a linear buckling strength of at least 400 N/rn, said insert extending to outermost edges of the glass sheets without extending past the outermost edges of the glass sheets; and a sealing element configured to seal an inside of the insulating glazing unit, wherein the insert is in a form of a substantially flat profiled strip that girds a perimeter of the insulating glazing unit by its internal face being pressed against edges of the at least two glass sheets and held fast by a fastener, a desiccant is associated with said insert, the insulating glazing unit does not include a spacer contacting facing surfaces of the glass sheets, and the insulating glazing unit does not include a metal coating contacting a facing surface of either of the glass sheets. 22. The insulating glazing unit recited in claim 21, wherein said desiccant is partially or completely intrinsically incorporated into said insert material. 23. The insulating glazing unit recited in claim 21, wherein said desiccant is deposited on said internal face of said insert.
