Definitions

  • the present invention relates to a spacer profile for forming a spacing between glass panes, said spacer profile having improved torsion resistance.
  • the spacer profile comprises a spacer body made of a synthetic material and having a compartment enclosed by an inner wall, an outer wall, a first side surface and a second side surface.
  • the spacer profile further comprises a diffusion barrier and at least two reinforcement elements being separated by a distance.
  • spacers made of various materials and of various shapes are known in the art. Spacers made by roll formed of a metal foil are widely used in the art and considered one of the preferred alternatives because of their stability and their low gas diffusion properties.
  • Insulating Glass Units having a plurality of glass panes are made by automatic manufacturing machines. Spacers are bent automatically to the desired size and shape and are arranged between two neighbouring glass panes. Spacers made of metal foils are easily bent and will remain in such bent position.
  • spacers made of metal foils have a high resistance against diffusion of gases and moisture penetration.
  • a gas is arranged, for instance argon having good insolating properties.
  • the spacers delimiting the cavity need to be resistant against diffusion of such gaseous elements.
  • spacers which are exclusively made of metal, such as aluminium and galvanised steel, also have some disadvantages. Due to a relatively high heat conductivity of metal, spacers made of a metal foil still have a heat conductivity which may be too high under certain circumstances.
  • plastic/polymer material for forming such spacers.
  • plastic material has relatively high gas diffusion as compared to metal.
  • Such a spacer is shown in e.g. EP 0852280B2 .
  • diffusion barriers of other materials in combination with a reinforcement layer extending from one side of the spacer to the other side.
  • the reinforcement materials have a higher heat conductivity i.e. a lower resistance to transfer of heat through the material.
  • spacers have been developed, where the reinforcements are divided into at least two separated pieces. Examples of such spacers are illustrated in EP3781774A1 and EP3162999A1 .
  • a spacer profile made of a synthetic material is reinforced with at least two separated reinforcement elements and in addition to that is provided with a diffusion barrier covering at least a part of the outer surface.
  • the inventors have found a solution to the torsion problem by adding materials to the spacer body.
  • a spacer profile for use as part of a spacer profile frame, which is suitable for being mounted in and/or along an edged area of an insulating glazing unit so as to surround an intervening space between glazing panes, the spacer profile comprising a spacer body made of a synthetic material and extending in a longitudinal direction (Z), said spacer body comprising:
  • the profile body further comprises areas with reduced thickness.
  • areas with reduced thickness the folding of the spacer profile can be controlled during bending into a spacer frame.
  • the synthetic material comprises 15-50 w/w% talc and/or fiberglass, more preferred is 20-45 w/w%.
  • the first and the second reinforcement elements each has an end located closer to the inner wall than to the diffusion barrier, and said end comprises at least four bendings and one of them being a 180 degree bend resulting in two parallel and overlapping layers, where said overlapping layers are essentially perpendicular to the first and second sidewalls, respectively.
  • the first bending is between 45 degrees and 135 degrees. This has the effect of a better absorption of the forces during bending of the spacer profile into a frame for the IGU and therefore results in less wrinkles on the side walls. Wrinkles are not desires as they can result in leaking from the interior of the IGU.
  • first and the second reinforcement elements have two ends, and each end is terminated with a 180 degree bend.
  • first and the second reinforcement elements are positioned at least on and partially in the first and second sidewalls, respectively. In an alternative embodiment, the first and the second reinforcement elements are positioned inside the profile body.
  • a part of the diffusion barrier is positioned between the first and second reinforcement elements and the first and second sidewalls, respectively.
  • the first and the second side walls each comprises a slanting elongation element.
  • the purpose of the slanting element is twofold. It makes a better and smoother connection with the diffusion barrier extending from the first side wall to the second side wall. It also makes additional room for the primary/secondary sealings, when the spacer profile is mounted in the IGU.
  • the profile body further comprises an outer wall positioned on the inner side of the diffusion barrier.
  • the spacer profile further comprises a first connection element connecting the first sidewall with the outer wall and an a second connection element connecting the second sidewall with the outer wall.
  • the spacer profile further comprises both an outer wall and two connection elements connecting the sidewalls with the outer wall.
  • the previously described variants further comprise a third and a fourth reinforcement element.
  • Said third and fourth reinforcement elements can have many shapes, but wires, flattened wires, threads are preferred.
  • the third and fourth reinforcement elements can be made of a metal such as stainless steel, alumina or tin.
  • a spacer profile for use as part of a spacer profile frame, which is suitable for being mounted in and/or along an edged area of an insulating glazing unit so as to surround an intervening space between glazing panes, the spacer profile comprising a spacer body made of a synthetic material and extending in a longitudinal direction (Z), said spacer body comprising:
  • first and the second reinforcement elements are positioned at least on and partially in the first and second sidewalls, respectively. In an alternative embodiment the, first and the second reinforcement elements are positioned inside the profile body.
  • first and the second reinforcement elements have two ends and each end is terminated with a 180 degree bend.
  • the previously described variants further comprise a third and a fourth reinforcement element.
  • Said third and fourth reinforcement elements can have many shapes, but wires, flattened wires, threads are preferred.
  • a particularly suited spacer profile according to the invention is a spacer profile for use as part of a spacer profile frame, which is suitable for being mounted in and/or along an edged area of an insulating glazing unit so as to surround an intervening space between glazing panes, the spacer profile comprising a spacer body made of a synthetic material and extending in a longitudinal direction (Z), said spacer body comprising:
  • first and the second reinforcement elements have two ends, and each end is terminated with a 180 degree bend.
  • the third reinforcement element is positioned between the first reinforcement element and the chamber, whereas the fourth reinforcement element is positioned between the second reinforcement element and the chamber.
  • the spacer body has areas with reduced thickness. Such areas have the effect that the folding of the spacer profile when being bended into a spacer frame can be controlled.
  • the areas with reduced thickness are positioned near the corners and/or near the connection between the sidewalls with the connection elements and/or near the connection between the connection elements and the outer wall.
  • the diffusion barrier has one of the following configurations. Diffusion barriers of the following configurations have shown to be particularly compatible with spacer profiles with separated reinforcements elements.
  • the diffusion barrier can be a barrier made of inorganic materials, or the diffusion barrier can made of a polymeric material.
  • the diffusion barrier can be a single sheet, or it can be of multiple overlapping sheets.
  • Suitable polymeric diffusion barriers are made of materials such as ethylene-vinyl-alcohol copolymers (EVOH) or polyvinyl alcohols.

  • Preferred inorganic diffusion barriers are metal layers or aluminium oxide layers or SiOx layers, where 1 ⁇ x ⁇ 2.
  • inert gasses such as argon can be contained in the intervening space between the glass panes by one of the layers, while another layer keeps moisture out of the intervening space.
