  • the method comprises: arranging edge mass to a space between edges of said two adjacent glass plates, which edge mass is configured to fix said at least one mounting unit between the said two adjacent glass plates, mounting said at least one mounting unit to the space between the said two adjacent glass plates, and removing the edge mass protruded from the space.
  • the mounting unit is mounted to the space between the said two adjacent glass plates so that the upper edges of the mounting devices of the mounting unit are at the same level as the edges of the glass plates.
  • the mounting unit is mounted to the space between the said two adjacent glass plates so that the upper edge parts of the mounting devices with the protrusions are configured to remain above the level of the glass plates of the insulating glass unit when mounted between the glass plates.
  • the mounting unit is mounted to the space between said two adjacent glass plates so that the mounting devices are embedded between the glass plates of the insulating glass unit.
  • Structural glazing systems i.e. facades are types of curtain wall systems consisting of a plurality of insulation glass units fixed i.e. attached next to each other in horizontal and/or vertical directions. Insulation glass units may be fixed, for example, bonded or anchored back to a supporting structure that may be called a frame profile by fixing means without the use of frames, for example continuously gasketed aluminium pressure plates or caps or some other structures, like glazing beads, arranged on the surface of the glass i.e. on the exterior. However, in some structural glazing systems exterior may be partially framed and some structural glazing systems may comprise insulation glass units with structural sealant punctually anchored.
  • Insulation glass units may be comprised of monolithic, laminated, dual-glazed (two overlapping glass plates) or triple-glazed (three overlapping glass plates) insulating glass units or facade glazing systems. It is however possible that an insulation glass unit comprises more than two or three glass plates, for example, four or five overlapping glass plates.
  • the back side of an insulation glass unit is configured to be connected to a frame profile that is fixed, for example, to a wall of a building.
  • the frame profile may be formed of, for example, horizontal and/or vertical aluminium profiles, beams or frames.
  • An insulation glass unit may be attached to the frame by mechanically attaching the inner glass or second inner glass of the insulation glass unit that is towards the frame profile, for example, by fixing means.
  • the glass plates are bonded on top of each other by glue.
  • the fixing means may be a fastener comprising one or two holding arms.
  • the fastener is configured to be inserted between two adjacent insulation glass units both comprising a fastening groove between overlapping glass plates, and when holding arms are aligned with fastening grooves the holding arms are rotated into the fastening grooves and the fastener is tightened for supporting the insulation glass units in place.
  • insulation glass units may be attached to a frame profile(s), which is/are already attached to a wall(s) of a building, by mechanical fixing means, for example, fasteners.
  • the insulation glass units are fixed against the seal or seals arranged on the surface of the frame profile. It is important that fastening grooves are at the same level in both adjacent insulation glass units, otherwise it is possible that another insulation glass unit is tightened too loose or tightly. If an insulation glass unit is attached to the frame profile too loose, it is possible that, for example moisture, air and/or water flows/comes in the structural glazing system in an undesirable manner and causes problems for the building and/or the structure of the structural glazing system. Whereas, if an insulating glass unit is attached to the frame profile too tightly, it can cause stress on the glass and as a result the glass may break.
  • tolerances in positions of fastening grooves of insulation glass units may cause challenges to fix the insulation glass units to the correct tightness to the frames.
  • Position tolerances of fastening grooves can be caused by manufacturing, because arranging a fastening groove between two overlapping glass plates of an insulation glass unit is not always easy and manufacturing tolerance of placement of fastening grooves may even be, for example, 1mm, which position tolerance is so big that it may cause difficulties.
  • fastening grooves are arranged in the same distance from glass plates of two overlapping glass plates of an insulation glass unit so that fasteners can be tightened with correct tightening torque.
  • non-aligned fastening grooves of adjacent insulation glass units may make the building of structural glazing systems slow or impossible and may increase costs or cause rejection of a glass unit or IGU as unfit for installation, as already explained in the background part above.
  • a mounting device used for controlling assembling i.e. mounting of a fastening groove to an insulating glass unit it is possible to mount and attach the fastening groove to an insulation glass unit so that position tolerances of fastening grooves between insulation glass units remain very low. Therefore, when a mounting device or devices according to the present invention is used for assembling a fastening groove, it is possible to use correct i.e. appropriate and adequate tightening torque for fixing insulation glass units in order to form a structural glazing system having correctly attached insulation glass units so that, for example, moisture, air and/or water cannot move in the structural glazing system in an undesirable manner and cause problems for the building and/or the structural glazing system.
  • a mounting device of the present invention configured to control mounting of a fastening groove into an insulating glass unit is a plate-like element i.e. thin sheet of material and comprises at least an inner guide wall, at least an outer guide wall or an inner guide wall and outer guide wall on one of its flat planar surfaces.
  • the form of the inner guide wall and outer guide wall are such that they correspond at least partially a cross section of the fastening groove in the transverse direction.
  • the inner wall is configured to rest i.e. settle against the inner surface of a fastening groove and the outer wall is configured to rest i.e. settle against the outer surface of the fastening groove, when the mounting device is attached to an end of the fastening groove.
  • the space which in a case where there are an inner wall and outer wall remains between the inner and outer guide walls, a fastening space, is arranged to correspond a cross section of an end of a fastening groove into which the mounting device is configured to be attached for controlling mounting of the fastening groove into an insulation glass element.
  • the inner wall is configured to rest i.e. settle against the inner surface of the fastening groove and the outer wall is configured to rest i.e. settle against the outer surface of the fastening groove, when the mounting device is attached to an end of the fastening groove.
  • the fastening groove comprises usually a mounting device in both of its ends.
  • Each insulation glass unit comprises at least one fastening groove provided on a section of the edge of the insulation glass unit, two or more fastening grooves provided on at least sections of the edge of the insulation glass unit, or the fastening groove may have a size of the whole length of the edge.
  • the number of fastening grooves or length of a fastening groove or grooves may depend on, for example, expected wind load or size of insulation glass units.
  • the fastening groove with mounting devices is configured to be mounted into an insulating glass element, between two of its glass plates, so that the upper edges of the fastening groove and mounting devices are at the same level with edges of glass plates. However, it is also possible that the upper edges of the fastening groove and mounting devices are not at the same level with edges of glass plates, they may be above or under the level of edges of glass plates.
  • a mounting device may be made, for example, of plastic, rubber, elastomer, composite, or metal, for example, stainless steel, or any other material suitable for the purpose. If a mounting device is made of elastic material, it may cause less point load to a glass plate or plates and/or it does not widen the space between the glass plates. However, it is also possible that a mounting device is made of non-elastic material i.e. rigid material, and it does not still either cause point load or widen the space between glass plates.

  • the other planar surface of the mounting device 100 does not comprise guide walls 101, 102, but it is flat.
  • the inner guide wall 101 is in one-piece, but the outer guide wall 102 is formed of three separate outer guide walls.

  • the upper edge part 110 comprises protrusions 110' on its both sides.
  • the idea of the wider front part 110 with its protrusions 110' is that the mounting devices 100 remain above the edge of the glass plates, i.e. they prevent mounting devices 100 from being pushed too deep between glass plates of an insulation glass unit. It is, however, possible that the front part 110 does not comprise protrusions 110' and is not thus wider than the guide wall part 112, see for example figures 2a-b, and 3a-d .
