    The invention relates to a spacer for insulating windows, an insulating pane and its use.
    The thermal conductivity of glass is about a factor of 2 to 3 lower than that of concrete or similar building materials. However, glazing is, in most cases, made considerably thinner than comparable materials of stone or concrete, and thus buildings often lose the greatest amount of heat through the exterior panes. This effect is particularly evident in high-rise buildings with partial or complete glass facades. The necessary extra cost for heating and air conditioning in a building is a considerable part of the maintenance costs that must not be underestimated. In addition, in connection with stricter building codes, lower carbon dioxide emissions are required. An important solution for this is insulation pane. Insulation windows cannot be avoided for building constructions, especially, in connection with rapidly rising commodity prices and stricter environmental regulations. Insulation windows therefore make up a larger proportion of outward-facing glass windows. Insulation panes usually contain at least two panes of glass or polymeric material. The panes are separated by a gas-filled room or an air-empty space defined by a spacer. The thermal insulation properties of insulating glass are significantly higher than single-layer glass and can be further enhanced and improved by three-layer glass or with special coatings. For example, silver-containing coatings enable a reduced transmission of infrared radiation and reduce the heating of a building in the summer. In addition to the important property of thermal insulation, optical and aesthetic properties also play a more important role in the field of building windows.
    Especially in buildings with an extensive exterior glass facade, the insulation effect is not only important because of the cost. As the heat insulation is usually poorer in very thin glass compared to the masonry, improvements in this area are necessary.
    In addition to the nature and structure of the glass, the additional components of an insulating pane are also of great importance. The seal and, above all, the spacer has a great influence on the quality of the insulating pane.
    Leaks in the spacer can easily lead to a loss of an inert gas between the insulating panes. In addition to deteriorating insulation ability, it can also easily lead to moisture penetration into the insulation pane. In the case of moisture buildup between the panes of the insulating pane, the optical quality deteriorates substantially and in most cases a replacement of the entire insulating pane is necessary.
    Attempts to improve the seal and the associated heat conductivity reduction are the provision of a barrier film on the spacer. This foil is usually fixed in the region of the outer seal of the spacer. Applicable foil materials include aluminum or stainless steel which has a good gas density. The metal surface also ensures a good adhesion of the spacer to the sealant.
    DE 40 24 697 A1 shows and describes a waterproof multilayer insulation pane comprising at least two glass panes and a profile spacer. The sealing is carried out via polyvinylidene chloride sheets or spacers on the spacer. Further, the edge adhesion can be carried out using a polyvinylidene chloride-containing solution.
    EP 0 852 280 A1 shows and describes a spacer for multilayer insulation windows. The spacer comprises a metal foil at the adhesive surface and has a fiberglass portion in the plastic abyss.
    DE 196 25 845 A1 shows and describes an insulating pane unit with a spacer of thermoplastic olefins. The spacer has a water vapor diffusion of less than 1 (g mm) / (mm2 d) as well as a high tensile strength and shore hardness. Furthermore, the spacer includes a gas-tight foil as a water vapor barrier.
    EP 0 261 923 A2 discloses and describes a multilayer insulation pane with a spacer of a moisture-permeable foam with an integrated desiccant. The device is preferably sealed through an outer seal and a gas and moisture-proof film. The film may contain metal-coated PET and polyvinylidene chloride copolymers.
    The object of the invention is to provide a spacer for an insulating pane, which enables improved, long-term stable insulating effect and at the same time enables easier installation.
    The object of the present invention is solved by a spacer according to the independent claim 1. Preferred embodiments are set forth in the subclaims.
    Further, an insulating pane and its use according to the invention appear from the further independent claims.
    The spacer according to the multi-layer insulation pane production comprises at least one composite of a fiberglass reinforced polymeric base member and a polymeric insulation foil. Through the selection of the fiberglass proportion in the base element, the coefficient of thermal expansion of the base element can be varied and adjusted. By adjusting the heat expansion coefficient of the base element and the polymeric insulating foil, temperature-related stresses between the various materials and peeling of the insulating foil can be avoided. The base member preferably has a glass fiber content of from 20% to 50%, especially preferably from 30% to 40%. At the same time, the fiber content of the basic element improves strength and stability. The base element comprises two parallel-running pane contact surfaces, an adhesive surface and an interior pane surface. The first pane contact surface and the second pane contact surface as well as the adhesive surface are directly connected or alternatively connected to each other via connecting surfaces. The two connecting faces preferably have an angle of 30 ° to 60 ° to the window contact surfaces. On the adhesive surface or alternatively on the adhesive surface and the connecting surfaces there is the insulating foil. The insulating film comprises at least one polymeric film in a thickness from 10 µm to 100 µm. The polymeric film provides at least one additional polymeric layer in a thickness of from 5 µm to 80 µm, as well as a metallic and / or ceramic layer having a thickness of from 10 nm to 1500 nm.
    In a preferred embodiment, the polymeric layer has a thickness from 10 µm to 100 µm. In another preferred embodiment, the thickness of the polymeric layer is 10 µm to 80 µm.
    In a particularly preferred embodiment, the polymeric film and polymeric layer are made of the same material. This is particularly advantageous as a small variety of materials used simplifies the production process. Thus, the same materials are preferably used for the polymeric film and polymeric layers, so that the same starting material can be used for all polymeric components of the insulating film.
    The insulating film contains at least two metallic layers and / or ceramic layers arranged alternately with at least one polymeric layer. For example, the insulating film may consist of a polymeric film on which a metallic layer, an additional polymeric layer and another metallic layer are present. Preferably, however, the outermost layers are polymer-containing and are formed from the polymeric film and / or polymeric layer. Within an insulating film ceramic and metallic layers can also be used. The alternating components of the insulating foil can be joined by various methods in the prior art, e.g. applied to each other. Methods for applying metallic or ceramic layers are known to those skilled in the art. Connection of individual components can be done via an adhesive. The use of an insulating film comprising alternating layer order is particularly advantageous for sealing the system. As a result, a failure of a layer does not result in a loss of function of the insulating foil. By comparison, a small defect in a single-layer foil can already lead to complete failure. Furthermore, the application of more thinner layers over a thick layer is advantageous as the problems of internal adhesion increase with increasing layer thickness. Furthermore, thicker layers have a higher conductivity, so that such a layer is less thermodynamically suitable.
    The insulating film preferably has a gas permeation of less than 0.001 g / (m2 h).
    The composite of the base member and the insulating foil preferably has a PSI value of less (equal to) than 0.05 W / mK, especially preferably less (equal to) than 0.035 W / mK. The value 0.035 W / mK means that the composite loses less than 0.035 watts per meter edge length per Kelvin of the temperature difference. The insulating foil may be provided on the base member, for example it may be glued on. Alternatively, the insulating film may be coextruded with the base member.
    The polymeric film and / or polymeric layer preferably comprises polyethylene terephthalate, ethylene vinyl alcohol, polyvinylidene chloride, polyamides, polyethylene, polypropylene, silicones, acrylonitriles, polyacrylates, polymethylacrylate and / or copolymers or mixtures thereof.
    The metallic layer preferably contains iron, aluminum, silver, copper, gold, chromium and / or alloys or mixtures thereof. The metallic layer has a thickness of 10 nm to 400 nm, preferably a thickness of 10 nm to 300 nm, particularly preferably a thickness of 10 nm to 200 nm. In an alternative embodiment, the metallic layer has a thickness of from 30 nm to 400 nm. Within the layer thickness mentioned, a particularly good density of the insulating film is observed.
    The metallic layer is preferably provided on the insulating foil via vapor deposition.
    The ceramic layer preferably contains silica and / or silicon nitrides. The ceramic layer preferably has a thickness of from 10 nm to 200 nm.
    The polymeric layer preferably has a thickness of from 5 µm to 80 µm, especially preferably 10 µm to 80 µm.
    The polymeric film preferably has 2 to 4 metallic or ceramic layers. The polymeric film preferably has 1 to 4 polymeric layers.
    The polymeric film preferably has 2 metallic or ceramic layers and 2 polymeric layers in alternating order of metallic / polymer. The polymeric film has particularly preferred 3 metallic layers and 3 polymeric layers in alternating metallic / polymeric order.
    The base element preferably has a length or width from 5.5 mm to 8 mm along the interior space of the pane. The exact diameter depends on the dimensions of the insulation pane and the desired size of the gap.
    The base member preferably has a length or height from 5 mm to 30 mm along the pane contact surface.
    The basic element preferably contains a desiccant, preferably silica gel, molecular sieves, CaCl 2, Na 2 SO 4, activated carbon, silicate, bentonite, zeolite and / or mixtures thereof. The desiccant is preferably incorporated in a porous portion of the base member. The desiccant is preferably coextruded with the base member. Preferably, the interior space of the pane has openings which allow the absorption of the humidity through the incorporated desiccant into the base member.
    The base element preferably contains polyethylene (PE), polycarbonate (PC), polypropylene (PP), polystyrene, polybutadiene, polynitriles, polyesters, polyurethanes, polymethyl methacrylates, polyacrylates, polyamides, polyethylene terephthalate (PET), polybutylene terephthalate (poly) -butadiene-styrene (ABS), acrylic ester-styrene-acrylonitrile (ASA), acrylonitrile-butadiene-styrene - polycarbonate (ABS / PC), styrene-acrylonitrile (SAN), PET / PC, PBT / PC and / or copolymers or mixtures thereof.
    The production further comprises an insulating pane with at least two panes and one of the panes comprises the spacer according to the production. An outer insulation, preferably a plastic sealant, located in a space at the rim between the panes and the spacer according to the invention. The outer insulation preferably contains polymers or silane modified polymers, particularly preferably organic polysulfides, silicones, RTV (room temperature vulcanized) silicone rubber, HTV (high temperature vulcanized) silicone rubber, peroxide vulcanized silicone rubber / or silicone rubber / or / or polyacrylates. The panes contain materials such as glass and / or transparent polymers. The panes preferably have an optical transparency of> 85%. Basically, different geometries of the panes are possible, for example geometries such as rectangle, trapezoidal and rounded. The panes preferably have a heat protection coating. The heat protection coating preferably contains silver. To take advantage of the energy saving options, the insulation pane can be filled with noble gas, preferably argon or krypton, which reduces the heat transfer rate in the space of the insulation pane.
    The production further comprises the use of the spacer according to the production in multilayer panes, preferably in insulating panes.
    In the following we will explain the production in more detail with drawings. The drawings are purely schematic and not in correct scale. The drawings are not limiting the production. The drawings show:

    Figure 2 is a cross-sectional view of the insulating pane of the present invention;
    Figure 1 shows a cross section of the spacer (I) according to the invention. The fiberglass reinforced polymeric base member (1) comprises two parallel extending pane contact surfaces (1a, 1b) which contact the panes to produce an insulating pane.

Between the adhesive surface (1c) and the window contact surfaces (1a, 1b) are preferably arranged two angled connecting faces (1e, 1e '). The connecting faces (1e, 1e ') preferably run at an angle α (alpha) from 30 ° to 60 ° to the adhesive surface (1c). the fiberglass reinforced polymeric base member (1) preferably contains styrene-acrylonitrile (SAN) and about 30% to 40% by weight of fiberglass. The angled shape of the first connector (1e) and the second connector (1e ') improves the stability of the glass fiber reinforced polymeric base member (1) and allows for better adhesion, as shown in Figure 2 and the insulation of the spacer (I) according to the invention. Included on the adhesive surface (1c) is an insulating film (2) comprising at least one polymeric film (2a), one polymeric layer (2b) and two metallic layers (2c) or ceramic layers (2d), as shown in Figure 3. polymeric base member (1) and insulating foil (2) together provide a composite (7).

The composite (7) according to the production itself has a PSI value of less than 0.035 W / mK. The spacer according to the invention improves the insulation effect.
    Figure 2 shows a cross section of the insulating pane (II) according to the invention. Between a first insulating glass pane (5a) and a second insulating glass pane (5b) is arranged the fiberglass reinforced polymeric element (1) with the insulating film (2) attached thereto. The insulation foil (2) is disposed on both the adhesive surface (1c) and on the first connecting surface (1e) and the second connecting surface (1e '). The insulating foil (2), together with the outer insulating layer (4), insulates the interior space of the pane (6) and reduces the heat transfer from the fiberglass reinforced polymeric element (1) into the interior space of the pane (6). For example, the insulating foil may be secured with PUR hot melt adhesive on the polymeric base member (1). Between the window contact surfaces (1a, 1b) and the insulating glass panes (5a, 5b) is preferably arranged an insulation and adhesive layer not shown. These preferably contain polymeric or silane modified polymers, especially preferred organic polysulfides, silicones, RTV (room temperature vulcanized) silicone rubber, HTV (high temperature vulcanized) silicone rubber, peroxide vulcanized silicone rubber and / or addition silicone rubber, and / or addition . The first insulating glass pane (5a) and the second insulating glass pane (5b) preferably have the same dimension and thickness, the windows preferably having an optical transparency of> 85%. The insulating glass panes (5a, 5b) preferably contain glass and / or polymers, preferably flat glass, float glass, quartz glass, borosilicate glass, lime-sodium glass, polymethyl methacrylate and / or mixtures thereof. In an alternative embodiment, the first insulating glass pane (5a) and / or the second insulating glass pane (5b) may be designed as a composite glass pane. In this case, the insulating pane (II) according to the invention forms a three-ply or four-pane pane. Within the fiberglass reinforced polymeric element (1), a desiccant (3) is incorporated. The desiccant (3) can be incorporated either within a central cavity or in the fiberglass reinforced polymeric element (1). The interior space of the pane (1d) preferably comprises a smaller aperture or pores which allow a gas exchange with the interior space of the pane (6).

The insulation film (2) comprises a polymeric film (2a) (0 12 µm) of LLDPE (linear low density polyethylene), 3 polymeric layers (2b) of PET (0 12 µm) and 3 metallic layers (2c) of aluminum (0 50 nm). The metallic layers (2c) and the polymeric layers (2b) are in each case alternately incorporated on the polymeric film (2a). The metallic layers (2b) and the polymeric layers (2a) can also in each case have different layer thicknesses. The structure of the insulating foil (2) according to the invention lowers the thermal conductivity of the insulating foil compared to the traditional metal or plastic films. A composite (7) provided by said insulation foil (2) according to the invention and the glass fiber reinforced polymeric element (1) has a thermal thermal conductivity of less than 10W / mK. This smaller thermal conductivity of the spacer (I) according to the invention significantly increases the effect of an insulating pane.
