Definitions

  • Glazing unit and process for its manufacture
  • the invention relates to a glazing unit which has at least one first and second glass or plastic pane, which are connected to one another at a predetermined distance via a spacer profile or a thermoplastic intermediate layer, with at least one of the first and second glass or plastic panes being a transparent one on the inside of the glazing unit comprises electrically conductive coating and, in particular in an edge region thereof, a bus bar for electrically connecting the conductive coating. It also relates to a method for producing such a glazing unit.
  • Glazing is a function-essential and also from an aesthetic point of view important part of buildings and vehicles, in particular road vehicles, but is also occasionally used in household appliances or pieces of furniture or similar objects. Traditionally, their purpose is to ensure natural lighting of the interior and (in the case of buildings and vehicles) at the same time a view from this into the surroundings. Due to the increased demands of the users, and at the same time made possible by new technologies, glazing is increasingly being developed and produced that implement additional protection and comfort functions.
  • glazing units with controllable functions are also becoming increasingly important.
