Furthermore, the invention relates to a thermal insulation composite system according to spoke 7 and a method for producing a facade insulation according to Speech 14th
- Such facade insulation panels are mostly used in thermal insulation composite systems in which they are next to each other on a flat surface
- the facade insulation panels are typically glued to the building facade and fixed by means of plate dowel. These penetrate the façade insulation panels and, with their large dowel plates, secure the position of the facade insulation panels on the façade. On the outside of the facade insulation panels and the dowel plate is at a
- External thermal insulation composite system mounted external plaster, which usually has a flush with an embedded reinforcing layer and a finishing coat as the outer end.
- the facade insulation panels in such a thermal insulation composite system are exposed to loads due to their own weight, by hygrothermal effects and in particular by wind suction.
- the interaction of the adhesive mortar with the plate anchors causes the power dissipation and thus the stability of the thermal insulation composite system.
- the greatest mechanical load of the thermal insulation composite system is generally due to the wind suction forces. These lead perpendicular to the ground over the cross section of the thermal insulation composite system acting Tensile forces in this and thus also in their facade insulation panels, which are absorbed by the dowels and dissipated into the ground.
- the adhesive mortar remains out of consideration here in the stability tests. In tear tests for experimental determination of the required number of anchors no adhesive mortar is used.
- facade insulation elements or composite thermal insulation systems are described by way of example from EP 1 088 945 A2, EP 1 408 168 A1 and DE 103 36 795 A1.
- the facade insulation panels used for this purpose are formed as a homogeneous, single-layered mineral wool body, in particular rock wool is used.
- a two-layer facade insulation board with a compacted covering layer on the plaster side and an insulating layer with a lower density on the facade side is conventionally used for an insulation system according to WLG 035.
- Such multi-layer insulation boards can be made up, for example, from a mineral wool web produced according to DE 37 01 592 A1. This has a compressed cover layer, which consists of the same material as the lower layer and also has a laminar fiber orientation. In such a prefabricated facade insulation board can be due to the hard outer layer a good
- the product "Silatherm” is also known, which is also a two-ply Facade insulation board used to reach the heat conduction group 035.
- This insulation board has a lower layer of laminar mineral wool, which unfolds a good insulation effect in particular due to their fiber orientation.
- a cover layer with mineral wool in three-dimensional isotropic orientation of the fibers is arranged, which has significantly better strength properties than the lower layer with slightly poorer insulating properties.
- Such a mineral wool layer with three-dimensional isotropic fiber orientation can be achieved, for example, by the process according to DE 103 59 902 A1.
- a primary non-woven with a laminar fiber structure so largely parallel to the large surfaces aligned fibers, digested, ie isolated with the formation of mineral wool flakes, which can be done for example by means of combing rollers or carding machines. Subsequently, the respectively obtained mineral wool flakes or individual fibers are re-combined to form a secondary nonwoven, whereby this results in a quasi-isotropic fiber orientation in all three dimensions directions.
- WVP 1-035 "should not be sunk in the facade insulation board.
- the invention is therefore the object of developing a facade insulation board for the insulation of the outer facades of buildings so that they also sunk with countersunk dowels for systems with a design value of Thermal conductivity ⁇ ⁇ 0.040 W / mK can be used according to DIN EN 13162, without an increased number of plate anchors over the prior art for their attachment to the facade is required. Furthermore, an improved composite thermal insulation system and a method for producing such a facade insulation board should be provided.
- a facade insulation board with the features of claim 1. This is particularly characterized by the fact that the binder content in the region of a boundary layer between the top layer of mineral wool with increased strength against the strength of the laminar lower layer (hereinafter referred to as "top layer” without further specification) and the laminar lower layer greater than in the other areas is.
- the invention thus provides for the first time an inhomogeneous binder distribution over the thickness of a facade insulation board.
- the combinatorial interaction of the advantageous in terms of thermal insulation laminar undercoat with the cover layer which combines the advantage of a further good thermal insulation behavior with the other advantage of good inherent stability of the layer, as well as an integral in the Boundary layer between this cover layer and the laminar lower layer present situation with increased binder content can achieve a facade insulation board, which is characterized by a particularly reliable stability.
- Frame of a thermal insulation composite system can be worked. It thus accounts according to the invention labor-intensive, time-consuming and costly additional work for the attachment of additional plate dowels.
- plate anchors with a diameter of the dowel plate of less than 90 mm can be used for mounting the inventive facade insulation board.

- the cover layer may be formed from a mineral wool with a three-dimensional isotropic arrangement of the fibers.
- the cover layer may consist of consist of compressed mineral wool.
- a three-dimensional compression of the mineral wool is preferred, as described for example in DE 198 60 040 Al, to which reference is made for technical details.
- the cover layer can also be formed as a laminar mineral wool layer with an increased density compared to the laminar lower layer. In this case, the bulk density of this laminar cover layer is more than 150 kg / m 3 , in particular more than 180 kg / m 3 .
- the mean binder content in the cover layer is greater than the average binder content in the laminar lower layer. It has been shown that this can be improved in a particularly effective manner, the inherent stability of the facade insulation board according to the invention, without this would go to the detriment of the thermal insulation ability to a considerable extent.
- the additional binder brings about a particularly effective connection of the individual fibers and thus an advantageous stiffening of the structure. Feraer it is also possible that the fibers in the cover layer have a larger average diameter than those in the laminar lower layer. It has been shown in tests that this measure leads to a further stabilization of the cover layer and thus the improvement of the stability of the facade insulation board according to the invention.
- the larger diameter fibers in the top layer provide improved distribution of induced forces to adjacent areas, so that transverse tensile loads can be particularly well absorbed by, for example, wind suction forces.
- the layer thickness of the cover layer is designed so that after sinking a plate dowel in the cover layer plus possibly deeper outcrops or incisions in the course of dowel insertion remains sufficient for the load transfer residual layer of the cover layer. Due to the comparatively poorer thermal conductivity of the cover layer, it is preferable not to make this layer thicker than necessary. In practical tests with products of nominal thicknesses of 100 and 120 mm, a ratio of the layer thicknesses of about 60% lower layer to 40% upper layer has proven to be particularly suitable for achieving a system with a thermal conductivity ⁇ of less than 0.040 W / mK. If the laminar
- the thickness ratio of the outer layer and the lower layer preferably decreases with increasing thicknesses of the facade insulation elements according to the invention.
- the facade insulation board according to the invention satisfies a design value of the thermal conductivity ⁇ ⁇ 0.036 W / mK according to DIN EN 13162, which is possible by the measures according to the invention, it can be advantageously achieved even for a system of heat conduction group 035 and therefore meets the highest requirements in terms of regulations for energy saving.

- an advantageous composite thermal insulation system can be achieved which, in view of the facade insulation panels according to the invention, is suitable even for insulation systems with a design value of the thermal conductivity of ⁇ ⁇ 0.040 W / mK.
- plate anchors the number of which must not exceed that of conventional facade systems due to the improved mechanical properties of the facade insulation panels according to the invention.
- thermal insulation composite system according to the invention can achieve a dowel image on the finished facade, which is optically substantially equal to the appearance of a system according to the prior art with plate anchors with a plate diameter of 90 mm and with a ⁇ ⁇ 0.036 W / mK , while avoiding the thermal bridges of the prior art.
- the effective diameter of the anchor plate can be less than 70 mm, in particular about 60 mm, which can reduce the workload as well as the costs on.
- Incorporate means in the facade insulation board, without causing an impairment of adjacent to the sinking fiber structure.
- the facade insulation panels have an incision in the support region of the anchor plate whose shape substantially corresponds to the peripheral line of the anchor plate, wherein the anchor plate is recessed in this area in the facade insulation board.
- a removal of the mineral fiber material in the region of the sinking of the plate dowel is not mandatory and the remaining material even advantageous to further improve the strength properties and thus the stability of the system can be used.
- the incision removes the structural relationship between the mineral wool material covered by the dowel plate and the adjacent areas; At the same time, however, the material present here is compressed when tightening the plate dowel and acts as an improved counter bearing for the tightening force of the dowel.
- the plate dowel sits therefore particularly stable in the facade insulation board and allows an even more reliable fastening the same on the facade.
- this compressed mineral wool material under the dowel plate combinatorially cooperates in a particularly advantageous manner with the given in the facade insulation board according to the invention layer with increased binder content, so that there is a further improvement in the stability of the system.
- the depth of the incision is less than the thickness of the cover layer, wherein the residual thickness of the cover layer remaining at the incision is preferably at least 5%, in particular at least 10%, and particularly preferably at least 20% of the total thickness of the cover layer.
- Residual thickness is an advantageous distribution of the loads on adjacent areas within the outer layer possible. As a result, the stability of the thermal insulation composite system according to the invention can be further improved.
- the recessed dowel plate When the recessed dowel plate is covered by a plug, advantageously results in a substantially continuous surface on the outside of the insulating layer.
- the plug consists of mineral wool material, since then there is a uniform material on the outside of the insulating layer throughout. The associated elimination of the thermal bridge then the risk is less, that the points of the plate dowels are visible over the years on the facade.

- the facade panel according to the invention can be produced particularly favorable.
- the provision of the second nonwoven mineral wool web includes the step of breaking up a laminar mineral wool web with uncured binder, then recombining the digested mineral wool material to form the second mineral wool nonwoven having three dimensional isotropic fiber orientation, then this layer can be reliably and inexpensively manufactured.
- a suitable procedure for this purpose is explained, for example, in DE 103 59 902 A1, so that further details can be dispensed with here.

This can be done as an alternative or in addition to the above-described methods of producing the desired binder concentration according to the invention and represents another, procedurally favorable way how the binder concentration in the boundary layer between the cover layer and the lower layer can be adjusted.
- the second mineral wool raw nonwoven a larger amount of binder is added as the first mineral wool raw nonwoven, and this can also be done procedurally with little effort.
- the fibers in the second mineral wool raw fleece can be formed with a larger average diameter than those in the first mineral wool raw fleece. Even such a variation of the fiber dimensions can be procedurally carried out by means known per se without problems and allows the achievement of the desired improved material properties in the final product.

- the facade insulation panel 4 can also be provided with the following parameters:
- the cover layer is provided as a three-dimensionally compressed mineral wool according to the procedure of DE 198 60 040 A1 with a bulk density of about 130 kg / m 3 and a binder content of about 4% with a layer thickness of about 60 mm.
- the underlayer with a layer thickness of about 140 mm has a bulk density of about 100 kg / m 3 and a binder content of about 3.5%.
- the binder content of the boundary layer is adjusted to about 5%, so that there is an average binder content of about 3.9% for the Fassadendämmelement invention.
- the cover layer is provided in the form of a laminar mineral wool layer increased density of about 200 kg / m 3 with a binder content of about 4% with a layer thickness of about 50 mm.
- the underlayer with a layer thickness of about 110 mm has a bulk density of about 100 kg / m 3 and a binder content of about 3.5%.
- the binder content of the boundary layer is adjusted to about 5%, so that there is an average binder content of about 3.8% for the Fassadendämmelement invention.
- these two variants can be produced by bonding the hardened layers provided with the parameters mentioned, or the hardened covering layer is fed to a hardening process together with the uncured laminar sublayer.
- the mean binder content in the cover layer 42 is greater than the average binder content in the underlayer 41; Rather, these binder proportions can be about the same. It is also possible that the binder content in the entire Fassadendämmplattenquerites with the exception of an edge layer 41a is set at the same level.
- the fibers in the cover layer 42 are according to the invention with a larger diameter
- Diameter formed as that of the lower layer 41 is not absolutely necessary, but also identically configured fibers can be used.
- FIG. 1 As a material for the facade insulation board 4 is shown in FIG. 1
- Example used rockwool Although it is also possible to form, for example, the underlayer 41 and / or the cover layer 42 of glass wool.
- the ratio of the layer thicknesses of the underlayer 41 to the cover layer 42 is not limited to the factor 60:40 explained and can be varied in both directions, depending on the application.
- the present invention proposes for the first time a facade insulation board for the insulation of external facades of buildings, in particular as part of a thermal insulation composite system, which is formed of bonded mineral wool and a design value of thermal conductivity ⁇ ⁇ 0.040 W / mK according to DIN EN 13162 fulfilled.
- the facade insulation board has an underlayer and a cover layer.
- the lower layer is made of laminar mineral wool.
- the cover layer has Mineral wool with increased mechanical strength compared to the lower layer.
- the proportion of binder for the first time in the region of a boundary layer between the cover layer and the laminar lower layer is greater than in the other areas.
- the present invention discusses a thermal insulation composite system with such a new facade insulation board.
- the present invention provides a method for producing such a facade insulation board.
