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 further relates to a frame comprising a windowpane according to the invention.
  • the invention furthermore relates to a window comprising a casing and a frame according to the invention.
  • the invention further relates to a glass panel for use in a windowpane with multiple glazing comprising 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, wherein the glass panel has a substantially flat outer surface and a substantially flat inner surface at room temperature.
  • 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.

  • Figure 4 shows a window comprising a windowpane with double glazing according to the present invention.
  • Figure la shows a windowpane 1 with double glazing according to the prior art.
  • Known windowpanes with double glazing comprise a first glass panel 2 composed of a single sheet of glass and a second glass panel 3 composed of a single sheet of glass.
  • the space between the two glass panels 2, 3 is hermetically sealed and is referred to as a cavity 4.
  • the cavity 4 may be filled with air or a gas mixture.
  • Figure lb shows the windowpane from Figure la at a low internal air pressure in the cavity 4 caused by a low temperature with respect to room temperature.
  • the windowpane is concave as a result of a change in temperature.
  • Figure lc shows the windowpane from Figure la at a high internal air pressure in the cavity 4 caused by a high temperature with respect to room temperature.
  • the windowpane is convex as a result of a change in temperature.
  • Figure 2a shows glass panel 2,3 for a windowpane with double glazing.
  • the glass panel 2,3 has a first sheet of glass 8 having a first coefficient of expansion and a second sheet of glass 9 having a second coefficient of expansion differing from the first coefficient of expansion.
  • the first sheet of glass 8 has a greater coefficient of expansion.
  • the first sheet of glass 8 is bonded to the second sheet of glass 9 via a bonding surface 10.
  • Figure 2b shows the glass panel of Figure 2a in the event of a decrease in temperature.
  • the glass panel is concave as a result of a change in temperature, seen from the first sheet of glass 8 to the second sheet of glass 9.
  • Figure 2c shows the glass panel of Figure 2a in the event of an increase in temperature.
  • the glass panel is convex as a result of a change in temperature, seen from the first sheet of glass 8 to the second sheet of glass 9.

  • the windowpane 1 with double glazing according to the present invention comprises a first glass panel 2 and a second glass panel 3.
  • At least one of the glass panels comprises a plurality of sheets of glass 8, 9 having different coefficients of expansion, wherein a first bonding surface 10 of a first sheet of glass 8 is bonded to a second bonding surface 10' of a second sheet of glass 9.
  • the first sheet of glass 8 has a greater coefficient of expansion and is situated on the cavity side of the glass panel 2, 3.
  • the glass panel thus formed has a substantially flat outer surface.
  • Figure 3b shows the windowpane 1 from Figure 3 a at a low internal air pressure caused by a low temperature with respect to room temperature.
  • a bending caused by expansion will compensate for the bending caused by the interfraction (see Figure lb).
  • the glass panel 2, 3 will remain substantially flat.
  • Figure 3c shows the windowpane 1 from Figure 3a at a high internal air pressure caused by a high temperature with respect to room temperature.
  • a bending caused by expansion will compensate for the bending caused by the interfraction (see Figure lc).
  • the glass panel 2,3 will remain substantially flat.
  • Figure 4 shows a window 11 in an opening of a wall comprising a casing 12 and a frame 13 arranged in the casing.
  • the casing 12 can be configured as a framework of wood, metal or plastic.
  • the frame 13 can be displaceable, preferably hingeable, between a closed position, in which the frame 13 seals an opening in the casing 12, and an open position.
  • the frame 13 is provided with a windowpane 1 comprising one or more glass panels according to the invention.
