Definitions

  • the invention relates to a window frame for insulating glass window, an insulating glass unit, an insulating glass window and a method for producing an insulating glass window.
  • Insulated glass windows are indispensable in building construction, especially in the context of ever faster rising raw material prices and stricter environmental protection regulations.
  • Insulating glass windows consist essentially of an insulating glass unit and a window frame.
  • the insulating glass units usually contain at least two panes of glass or polymeric materials.
  • the disks are separated from each other by a gas or vacuum space defined by the spacer.
  • the thermal insulation capacity of insulating glass units is significantly higher than that of simple glass panes and can be further increased and improved in triple insulating glass units or with special coatings.
  • an insulating glass unit is first made of at least two panes and a spacer arranged therebetween, which is sealed and fixed at the edge by means of adhesive and sealing means. This finished insulating glass unit is then installed in a window frame system.
  • insulating glass units are padded or glued into a window frame or other system. When messing up the insulating glass unit is inserted into the frame and fixed in the frame by means of blocks. This procedure can only be successfully carried out by trained specialists. The glass manufacturers each issue their own blocking guidelines.
  • the materials of the sealant and the blocks must be exactly matched, otherwise material incompatibilities occur. It is therefore desirable to develop suitable systems that allow the simplified assembly of insulating glass windows, without leading to material incompatibilities and at the same time do not affect the gas and vapor-tight design of the insulating glass unit.
  • An alternative to the clogging of insulating glass units is the gluing of insulating glass units in the window frame. Suitable adhesives, which can fix the insulating glass unit stably in the window frame, are known in the art. When gluing, it is critical to avoid material incompatibility between the adhesive and the secondary sealant material. Therefore, for a long-lasting stable Gluing the insulating glass unit in the window frame a previously matched system of adhesive and secondary sealant can be used.
  • DE 3532814 A1 discloses an insulating glass unit which is mounted in a peripheral frame which has a two-part profile which is intended to facilitate installation in a frame.

  • the first profile is firmly connected to the insulating glass unit along the end faces of the insulating glass unit.
  • the first profile is designed so that the individual window edges of the insulating glass unit rest on the profile.
  • the second profile which can be connected to the first profile, can be varied depending on the installation situation and takes over, for example, decorative functions, and serves to clamp the individual glass panes in the two-part profile.
  • the pinching of the discs in the profile leads to increased pressure on the discs.
  • WO91 / 08366 discloses a window frame profile with integrated spacer for an insulating glass window. To the right and left of the side walls of the spacer, two upstanding side wings are provided, so that the glass panes can be clamped in the resulting recesses. This creates pressure on the glass panes, which leads to increased loading of the panes after installation.
