Definitions

  • the invention relates to a spacer for insulating glazing, its use, a glazing and a method for their preparation.
  • thermal conductivity of glass is about a factor of 2 to 3 lower than that of concrete or similar building materials.
  • slices are in most cases much thinner than comparable elements made of stone or concrete, buildings often lose the largest proportion of heat through the exterior glazing.
  • the additional costs for heating and air conditioning systems make up a not inconsiderable part of the maintenance costs of a building.
  • lower carbon dioxide emissions are required as part of stricter construction regulations.
  • An important solution for this are multiple-pane insulation glazings, which are indispensable in building construction especially in the context of ever faster rising raw material prices and stricter environmental protection regulations.
  • Multiple-pane insulation glazings, in particular triple-glazed glazings therefore constitute an increasingly larger part of the outwardly facing glazings.
  • Multiple insulation glazings typically include glass or polymeric materials which are separated by spacers.
  • a second pane is placed on a double glazing by means of an additional spacer or a spacer used, which has a recess which is suitable for receiving a third pane.
  • the thermal insulation capacity of triple insulating glass is significantly increased compared to single or double glazing. As the number of panes increases, not only the thermal insulation capacity but also the weight of the multiple insulating glazing increases.
  • WO 2014/159163 A1 and US Pat. No. 4,335,166 A disclose multiple insulating glazings in which films are glued between two spacers and tightened by a temperature process.
  • CA 2 918471 A1 discloses multiple insulating glazings with films as separating elements.
  • the foils are each glued in a suspended suspension system.
  • low-E coatings offer an effective way of shielding infrared radiation before entering the living space while allowing daylight to pass through.
  • Low-E coatings are thermal radiation reflective coatings that reflect a significant portion of infrared radiation, resulting in reduced warming of the living space in summer.

  • Such low-E coatings can not be applied to a glued between two spacers film of multiple glazing according to the prior art, since the coating due to solar radiation heating of the film due to failure of the adhesive bond between the middle film and the spacers or between the foil and the suspended suspension system.
  • the anchor element extends into the cavity of the spacer filled with a desiccant, whereby there is the risk of the desiccant coating of desiccant in the spaces between the panes and the foil.
  • the anchor element in which the film is inserted, not firmly connected to the spacer, ie anchor element and spacers are not integrally formed, nor is the anchor member glued to the spacer. Therefore, the anchor element in strong pull through the film, the spacer in the area of the gap, in which the anchoring element is inserted, break open or at least greatly deform.

  • each of the grooves is able to form-fit the thickened edge of each film.
  • the positive recording of the thickened edge of the film in the groove of the spacer ensures a uniform force in the spacer.
