Definitions

• the invention relates to an insulating glass unit with an inner pane, an outer pane and a peripheral edge joint with edge joint filling.
• the insulating glass unit is particularly intended for window and facade cladding in the construction sector, but can also be used as a vehicle window.
• Such an insulating glass unit must absorb considerable thermal stresses from, for example, solar radiation at high outside temperatures on the one hand and from low outside temperatures during deep frost on the other hand.
• thermal stresses from, for example, solar radiation at high outside temperatures on the one hand and from low outside temperatures during deep frost on the other hand.
• the insulating glass unit to which the invention relates is designed to be soundproof and / or heat-insulating.
• the distance between the two glass panes must be set up and maintained with small tolerances. This also applies to the edge joint. High demands are placed on the sealing.
• the edge joint filling which consists of a reaction adhesive or a plastic, is used for this.
• Insulating glass units of the construction described are a pronounced mass product of industrial series production. They must be set up in such a way that they can be produced on modern automatic production facilities with a large number of units in the unit of time and safe and with a long service life meet all requirements of the very complex load spectrum.
• an edge joint filling which also functions as a spacer. It consists of reaction adhesive strands.
• the manufacturing process is such that the reaction adhesive strands protrude over the edge of the disc with a bead that has to be removed in a special manufacturing stage by mechanical reworking. This is complex from a manufacturing point of view and can be improved with regard to long-term tightness.
• a spacer designed as a hollow profile is provided in another insulating glass unit (EP 0 430 889 A2).
• an edge joint filling made of synthetic resin adhesive is arranged in another insulating glass unit.
• the hollow profile has a moisture absorbent Substance and holes towards the space between the panes.
• a water vapor and gas impermeable coating for example a metallic coating

• the subject of the invention is an insulating glass unit with an inner pane, an outer pane and a peripheral edge joint with edge joint filling, which can accommodate complex stresses when using the insulating glass unit in the construction sector and also to absorb extreme mechanical stresses, for example in the form of vibrations and Vibrations, as they occur in vehicles, is suitable, wherein the following features are realized: 1.1)
• the edge joint filling consists of a thermoplastic elastomer from the group of polyolefin mixtures (TPO), 1.2)
• TPO plastic is selected or mixed from the group according to 1.1) so that the edge joint filling has the following properties: Water vapor transmission rate (ASTM-F1249) ⁇ 1 g.mm/mm 2 .d

• IIR / PP butyl rubber / polypropylene
• the invention is based on the knowledge that some of the TPO plastics listed in feature 1.1) are suitable for the construction of the edge joint fillings in insulating glass units which are exposed to the complex range of stresses described at the outset.
• the individual members of the group in turn consist of a number of special variants that plastic chemistry specifies.
• the edge joint filling can be extruded and thereby shaped as such according to the desired geometry.
• any reworking is omitted because an end view surface is formed in accordance with feature 1.3). It is visible in the finished insulating glass unit between the inner pane and the outer pane and forms a smooth, flush closure with at least one of these panes. Surprisingly, tight tolerances can be met exactly. Alignment with one of the glass panes is established when the other glass pane protrudes with a guide edge. Close both glass panels flush ends, the edge joint filling made of TPO is flush with the edges of the two glass panes.
• the final visible surface which was formed during extrusion or continuous casting fulfills a double function in the context of the invention. Under the influence of the surface tension of the thermoplastic during extrusion and when it emerges from the extrusion die, it has formed practically non-porous and thereby improves the diffusion tightness, and thus serves not only as a visible surface.
• the teaching of the invention permits two fundamentally identical embodiments, which are specified in detail, however, in accordance with different uses.
• the insulating glass unit is preferably equipped with an inner pane, an outer pane and a spacer which runs around the edge to form the edge joint and is designed as a hollow profile, as well as the additional edge joint filling.
• the edge joint filling is expediently connected not only to the glass panes, but also to the hollow profile. This can be glued in turn.
• a particular advantage of the invention is that a gas and water vapor permeable coating, in particular a metal coating, is no longer required on the surface of the hollow profile facing the edge joint filling.
