Definitions

• the present invention relates to a windowpane with multiple glazing comprising a first glass panel, a second glass panel and a cavity arranged between the first glass panel and the second glass panel.
• the present invention further relates to a frame and a window comprising the above windowpane with multiple glazing.
• the present invention furthermore relates to a glass panel for a windowpane with multiple glazing and a method for the manufacture thereof.
• the space between two sheets of glass is hermetically sealed by means of a spacer and an edge seal at the air pressure prevailing at that time.
• the space between the sheets of glass may be filled with air or a gas mixture.
• Interfraction also occurs if there is a change in the air pressure between the sheets of glass as a result of a change in the temperature.
• the windowpane may thus become convex if the internal air pressure increases (temperature increase) and become concave in the event of a low internal air pressure (temperature decrease).
• sun protection in the cavity may fail, burning glass effects may arise or glass breakage may occur.
• the first glass panel comprises a first sheet of glass having a first coefficient of expansion and a second sheet of glass having a second coefficient of expansion differing from the first coefficient of expansion.
• a bonding surface of the first sheet of glass is bonded to a bonding surface of the second sheet of glass at a bonding temperature.
• the first glass panel has a preselected curvature which corresponds to a predetermined form (flat, convex or concave).
• the first glass panel may, for example, have a substantially flat outer surface and a substantially flat inner surface.
• the glass panel will bend in the event of a change in temperature. This is because one sheet of glass expands to a greater extent than the other. If the sheets of glass are in the correct order, from inside to outside, the bending caused by expansion will be able to reduce or even eliminate the bending caused by the interfraction (as a result of thermal effects). Particularly in the case of relatively large glass facades, reducing the interfraction effects will have the advantage of also reducing the burning glass effects.
• the second glass panel has a first sheet of glass having a first coefficient of expansion and a second sheet of glass having a second coefficient of expansion differing from the first coefficient of expansion, wherein a bonding surface of the first sheet of glass is bonded to a bonding surface of the second sheet of glass at a bonding temperature.
• the second glass panel preferably has the same predetermined form as the first glass panel.
• the windowpane according to the invention comprises a third glass panel arranged between the first glass panel and the second glass panel.
• the windowpane comprises sun protection means in the cavity.

• the invention furthermore relates to a method for manufacturing a glass panel according to the invention, comprising the steps of:
• the glass panel has a substantially flat outer surface and a substantially flat inner surface at room temperature.
• a ratio between the first coefficient of expansion and the second coefficient of expansion is between 0.999 and 1.001.
• first bonding surface is bonded to the second bonding surface by means of glass fusion, melting or gluing together.
• the bonding temperature for fusion or melting is between approximately 593°C and approximately 816°C, preferably between 593°C and approximately 816°C.
