Abstract
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.
Claims23
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.
