Stand der TechnikState of the art

Es sind bereits Hochhaus-Wärmedämm-Verbundsysteme zur Anbringung an einem Hochhaus, die wenigstens ein Wärmedämmelement aufweisen, bekannt.There are already high-rise thermal insulation composite systems for attachment to a high-rise building, which have at least one thermal insulation element known.

Weiter sind aus der DE 100 24 678 A1 Wärmedämmplatten aus Polystyrol (EPS/XPS) oder Polyurethan (PUR) bekannt, bei denen durch flächig verteilte kleine Bohrungen durch die Platte bei Erhaltung der charakteristischen Wärmedämmwerte eine Wasserdampfdiffusionszahl µ < 10 erreicht wird und über eine äußere Beschichtung aus LETON und diffusionsoffenen Farbanstrichen eine durchgängige niedrige Wasserdampfdiffusionszahl µ < 10 für das Fassadenwärmedämmsystem bei einer äußeren mechanischen festen Außenseite der Fassade erzielt wird.Next are from the DE 100 24 678 A1 Thermal insulation panels made of polystyrene (EPS / XPS) or polyurethane (PUR) are known in which by distributed small holes through the plate while maintaining the characteristic thermal insulation values a water vapor diffusion coefficient μ <10 is achieved and an external coating of LETON and vapor-permeable paints a continuous low Water vapor diffusion coefficient μ <10 is achieved for the facade thermal insulation system with an outer mechanical fixed outside of the facade.

Aus der DE 32 38 445 A1 ist eine wärmegedämmte Putzfassade bekannt, bei der die Dämmstoffplatten über Abstandshalter mit dem Untergrund derart verbunden werden, dass eine schwache - die Wärmedämmwirkung aber praktisch nicht beeinflussende - Hinterlüftung entsteht. Hierdurch wird überschüssiges Wasser während der Trocknungsphase für das System unschädlich abgeführt. Die Hinterlüftung kann nach Austrocknung aufgehoben werden.From the DE 32 38 445 A1 is a thermally insulated plaster facade known in which the insulation boards with spacers with be connected to the ground in such a way that a weak - the thermal insulation effect but practically not influencing - ventilation arises. As a result, excess water is removed harmlessly during the drying phase for the system. The rear ventilation can be lifted after dehydration.

Dadurch kann ein Hochhaus-Wärmedämm-Verbund-system realisiert werden, das eine vorteilhaft hohe Wärmedämmung bei einer vorteilhaft geringen Dicke der Wärmedämmplatten bereitstellt. Zudem können durch Wärmedämmelemente, die einen organischen Dämmstoff aufweisen, brandschutztechnische Anforderungen einfach erfüllt werden, wodurch ein effektives Hochhaus-Wärmedämm-Verbundsystem realisiert werden kann.According to the invention, the thermal insulation element has at least one insulating material which is at least partially organic. As a result, a high-rise thermal insulation composite system can be realized, which has an advantageously high thermal insulation with an advantageously small thickness of the thermal insulation panels provides. In addition, by thermal insulation elements that have an organic insulation, fire safety requirements can be easily met, creating an effective high-rise thermal insulation composite system can be realized.

Unter einem "organischen Dämmstoff" soll dabei insbesondere ein Dämmstoff verstanden werden, dessen chemische Zusammensetzung zumindest eine chemische Verbindung aufweist, die Kohlenstoff umfasst. Unter einer "chemischen Verbindung mit Kohlenstoff" soll insbesondere ein langkettiges Molekül verstanden werden, das wenigstens ein Kohlenstoffatom aufweist. Nicht darunter verstanden werden sollen sogenannte wasserstofffreie Chalkogenide des Kohlenstoffs, wie beispielsweise Kohlenstoffmonoxid, Kohlenstoffdioxid, Schwefelkohlenstoff sowie Kohlensäure und Carbonate, Carbide und ionische Cyanide, Cyanate und Thiocyanate. Unter "einem Hochhaus" soll dabei insbesondere ein Gebäude verstanden werden, dessen Gebäudehöhe eine festgelegte Höhe überschreitet. Die Höhe ist vorzugsweise durch eine amtliche Verordnung, wie beispielsweise eine Landesbauverordnung, festgelegt. Unter einer "Gebäudehöhe" soll insbesondere verstanden werden, dass eine Fußbodenhöhe von zumindest einem Aufenthaltsraum des Gebäudes zumindest 10 Meter, vorzugsweise zumindest 15 Meter und besonders bevorzugt zumindest 20 Meter über einer Geländeoberfläche liegt. Unter einem "Aufenthaltsraum" soll in diesem Zusammenhang insbesondere ein Raum verstanden werden, der zur regelmäßigen Nutzung vorgesehen ist, wie beispielsweise ein Büroraum oder ein Wohnraum.An "organic insulating material" is to be understood in particular as meaning an insulating material whose chemical composition comprises at least one chemical compound which comprises carbon. By a "chemical compound with carbon" is meant in particular a long-chain molecule having at least one carbon atom. Not to be understood as so-called hydrogen-free chalcogenides of carbon, such as carbon monoxide, carbon dioxide, carbon disulfide and carbonic acid and carbonates, carbides and ionic cyanides, cyanates and thiocyanates. By "a high-rise building" is meant in particular a building whose building height exceeds a specified height. The height is preferably determined by an official regulation, such as a state building regulation. A "building height" is to be understood in particular as meaning that a floor height of at least one common room of the building is at least 10 meters, preferably at least 15 meters and particularly preferably at least 20 meters above a terrain surface. In this context, a "common room" is to be understood as meaning, in particular, a room intended for regular use, such as, for example, an office space or a living space.

Weiter wird vorgeschlagen, dass das Hochhaus-Wärmedämm-Verbundsystem eine Hochhausfassadenhöhe von zumindest 22 Metern aufweist. Dadurch kann für ein Hochhaus eine besonders hohe Wärmedämmung erreicht werden. Vorzugsweise ist die Fassadenhöhe größer als 22 Meter, insbesondere wenn das Hochhaus zumindest einen Aufenthaltsraum aufweist, dessen Fußbodenhöhe zumindest 22 Meter über einer Geländeoberfläche liegt. Vorzugsweise ist die Fassadenhöhe durch eine Traufhöhe von zumindest 25 Metern definiert. Unter einer "Traufhöhe" soll dabei insbesondere eine untere Dachabschlusskante verstanden werden.It is also proposed that the high-rise thermal insulation composite system be a skyscraper façade height of at least 22 meters having. This can be achieved for a high-rise a particularly high thermal insulation. Preferably, the facade height is greater than 22 meters, in particular if the high-rise has at least one recreation room whose floor level is at least 22 meters above a terrain surface. Preferably, the facade height is defined by a eaves height of at least 25 meters. Under a "eaves height" is to be understood in particular a lower roof end edge.

Ferner wird vorgeschlagen, dass das Hochhaus-Wärmedämm-Verbundsystem eine Hochhausfassade aufweist, die mit dem wenigstens einen Wärmedämmelement zumindest teilweise verkleidet ist. Durch Verkleidung der Hochhausfassade kann eine einfache und kostengünstige Wärmedämmung realisiert werden. Unter einer "Hochhausfassade" soll in diesem Zusammenhang insbesondere eine Außenfläche des Hochhauses verstanden werden, die zur Anbringung der Wärmedämmelemente vorgesehen ist. Insbesondere soll darunter eine im Wesentlichen unverkleidete Wandfläche verstanden werden, auf die zur zusätzlichen Wärmedämmung die Wärmedämmelemente aufgebracht werden.It is also proposed that the high-rise thermal insulation composite system has a skyscraper facade, which is at least partially clad with the at least one thermal insulation element. By cladding the high-rise facade, a simple and cost-effective thermal insulation can be realized. In this context, a "high-rise facade" should be understood as meaning, in particular, an outer surface of the high-rise building, which is provided for mounting the thermal insulation elements. In particular, it should be understood as a substantially unclad wall surface, to which the thermal insulation elements are applied for additional thermal insulation.

In einer vorteilhaften Ausgestaltung wird vorgeschlagen, dass das zumindest eine Wärmedämmelement als eine Wärmedämmplatte ausgebildet ist, die dazu vorgesehen ist, die Hochhausfassade im Wesentlichen vollständig zu verkleiden. Dadurch kann ein Wärmeverlust durch ungedämmte Fassadenflächen verringert werden, wodurch insbesondere ein Energiebedarf zum Heizen eines entsprechenden Hochhauses gesenkt werden kann. Unter "im Wesentlichen" soll in diesem Zusammenhang insbesondere verstanden werden, dass zumindest 75 Prozent der Hochhausfassade mit zumindest einem, vorzugsweise jedoch mehreren nebeneinander angeordneten Wärmedämmplatten verkleidet ist.In an advantageous embodiment, it is proposed that the at least one thermal insulation element is designed as a thermal insulation panel, which is intended to substantially completely cover the high-rise facade. As a result, a heat loss can be reduced by uninsulated facade surfaces, which in particular an energy requirement for heating a corresponding high-rise can be reduced. In this context, "essentially" is to be understood in particular as meaning that at least 75 percent of the high-rise facade complies with at least one, but preferably several juxtaposed thermal insulation panels is covered.

Eine besonders vorteilhafte Dämmung kann zudem erreicht werden, wenn der Dämmstoff des wenigstens einen Wärmedämmelements im Wesentlichen aus einem organischen Material ausgebildet ist. Unter "im Wesentlichen" soll dabei insbesondere verstanden werden, dass ein Anteil der organischen Verbindungen in dem Dämmstoff zumindest 50% beträgt.A particularly advantageous insulation can also be achieved if the insulating material of the at least one heat-insulating element is formed substantially from an organic material. By "substantially" is meant in particular that a proportion of the organic compounds in the insulating material is at least 50%.

In einer besonders vorteilhaften Ausgestaltung ist der Dämmstoff des wenigstens einen Wärmedämmelements im Wesentlichen als ein Polyurethanschaum (PUR-Schaum) und/oder Polyisocyanuratschaum (PIR-Schaum) ausgebildet. Dadurch kann ein besonders vorteilhafter organischer Dämmstoff bereitgestellt werden.In a particularly advantageous embodiment, the insulating material of the at least one heat-insulating element is designed essentially as a polyurethane foam (PUR foam) and / or polyisocyanurate foam (PIR foam). As a result, a particularly advantageous organic insulating material can be provided.

Vorzugsweise weist das wenigstens eine Wärmedämmelement eine homogene Rohdichte auf. Durch eine homogene Rohdichte kann neben einem gewährleisteten guten Brandschutz bei einer vorgegebenen Isolationsstärke eine besonders gute Wärmedämmung erzielt werden. Unter einer "Rohdichte", angegeben in kg/m3, soll in diesem Zusammenhang insbesondere eine Dichte eines Materials verstanden werden, zu deren Ermittlung das Porenvolumen im Materialvolumen mit einbezogen wird. Unter einer "homogenen" Rohdichte soll in diesem Zusammenhang insbesondere verstanden werden, dass in einer Verteilung von Messwerten der Rohdichte, die an Probevolumina in Form von Würfeln mit einer Kantenlänge von 10 Millimetern bestimmt wird, die aus einem Teil des Wärmedämmelements von einer parallel zu einer äußeren Oberfläche liegenden Mittelebene durch einen Volumenmittelpunkt bis zu der äußeren Oberfläche gewonnen werden, mindestens 70% der ermittelten Messwerte der Rohdichte in einem Intervall von ±20%, insbesondere in einem Intervall von ±10%, um einen statistischen Mittelwert liegen. Der "Volumenmittelpunkt" soll in diesem Zusammenhang insbesondere als identisch mit einem Schwerpunkt des Wärmedämmelements bei einer als konstant angenommenen Rohdichte verstanden werden. Dabei wird insbesondere vorgeschlagen, dass die Rohdichte des wenigstens einen Wärmedämmelements größer als 26 kg/m3 und geringer als 80 kg/m3 ist.Preferably, the at least one thermal insulation element has a homogeneous density. Due to a homogeneous bulk density, in addition to a guaranteed good fire protection at a given insulation thickness, a particularly good thermal insulation can be achieved. In this context, a "bulk density", stated in kg / m 3 , is to be understood in particular to mean a density of a material for the determination of which the pore volume in the material volume is included. In this context, a "homogeneous" bulk density should be understood in particular to mean that, in a distribution of measured values of the bulk density, which is determined on sample volumes in the form of cubes with an edge length of 10 millimeters, that from a part of the heat-insulating element from one parallel to one outer surface lying median plane through a volume center are obtained to the outer surface, at least 70% of the measured raw density measurements are within an interval of ± 20%, in particular within an interval of ± 10%, to a statistical average. In this context, the "volume center" should be understood to be in particular identical to a center of gravity of the heat-insulating element with a raw density assumed to be constant. It is proposed in particular that the bulk density of the at least one heat-insulating element is greater than 26 kg / m 3 and less than 80 kg / m 3 .

Dadurch kann der Brandschutz weiter verbessert werden. Zudem kann dadurch eine vorteilhafte Oberflächengestaltung realisiert werden. Unter einer "Oberfläche" soll dabei insbesondere eine Fläche des Wärmedämmelements verstanden werden, die in montiertem Zustand parallel zu der Hochhausfassade orientiert ist.In one embodiment of the invention, it is proposed that the high-rise thermal insulation composite system has a cleaning system that is at least partially applied to at least one surface of the at least one heat-insulating element. As a result, the fire protection can be further improved. In addition, an advantageous surface design can be realized thereby. A "surface" is to be understood in particular as an area of the heat-insulating element which, in the mounted state, is oriented parallel to the high-rise facade.

Beschreibung der AusführungsbeispieleDescription of the embodiments

Die Figuren 1 und 2 zeigen ein Hochhaus mit einem erfindungsgemäßen Hochhaus-Wärmedämm-Verbundsystem. Das Hochhaus-Wärmedämm-Verbundsystem umfasst mehrere Wärmedämmelemente 10, die alle gleichartig ausgebildet sind. Die Wärmedämmelemente 10 sind als Wärmedämmplatten ausgebildet, die auf einer Hochhausfassade 16 des Hochhauses aufgebracht sind. In montiertem Zustand verkleiden die Wärmedämmelemente 10 die Hochhausfassade 16 im Wesentlichen vollständig. Von der Verkleidung ausgenommen sind Gebäudeöffnungen 24, wie beispielsweise Fenster, Türen oder in die Hochhausfassade 16 eingebrachte Belüftungsöffnungen.The FIGS. 1 and 2 show a skyscraper with a high-rise thermal insulation composite system according to the invention. The high-rise thermal insulation composite system comprises a plurality of thermal insulation elements 10, which are all formed identically. The thermal insulation elements 10 are formed as thermal insulation panels, which are applied to a high-rise facade 16 of the skyscraper. In the assembled state, the thermal insulation elements 10 substantially completely cover the high-rise facade 16. Excluded from the cladding are building openings 24, such as windows, doors or introduced into the skyscraper facade 16 vents.

Das Hochhaus weist eine Gebäudehöhe 26 von wenigstens 22 Metern auf. Das Hochhaus umfasst einen Aufenthaltsraum 28, dessen Fußbodenhöhe 30 wenigstens die 22 Meter über einer Geländeoberfläche 32 ist. Die Hochhausfassade 16 weist somit eine Hochhausfassadenhöhe 14 auf, die größer ist als die 22 Meter.The skyscraper has a building height 26 of at least 22 meters. The high-rise comprises a recreation room 28 whose floor level 30 is at least 22 meters above a terrain surface 32. The high-rise facade 16 thus has a skyscraper facade height 14 which is larger than the 22 meters.

Die Wärmedämmelemente 10 weisen einen Dämmstoff 12 auf, der teilweise aus organischen Verbindungen besteht. Der Dämmstoff 12 ist mittels Molekülketten ausgebildet, die Kohlenstoff enthalten. Ein Material, das den Dämmstoff 12 ausbildet, ist als Polyurethan ausgebildet. Alternativ oder zusätzlich kann der Dämmstoff 12 auch als Polyisocyanurat ausgebildet sein. Das Polyurethan bzw. das Polyisocyanurat ist zur Ausbildung der Wärmedämmelemente 10 aufgeschäumt. Der Dämmstoff 12 besteht somit im Wesentlichen aus Polyurethanschaum (PUR-Schaum) bzw. Polyisocyanuratschaum (PIR-Schaum).The thermal insulation elements 10 have an insulating material 12, which partially consists of organic compounds. The insulating material 12 is formed by molecular chains containing carbon. A material that forms the insulating material 12 is formed as a polyurethane. Alternatively or additionally, the insulating material 12 may also be formed as a polyisocyanurate. The polyurethane or the polyisocyanurate is foamed to form the thermal insulation elements 10. The insulating material 12 thus consists essentially of polyurethane foam (PUR foam) or Polyisocyanuratschaum (PIR foam).

Die Wärmedämmelemente 10 weisen eine homogene Rohdichte auf. Eine Dichte des Dämmstoffs 12, der die Dämmelemente 10 ausbildet, beträgt 32 kg/m3. Eine Wärmeleitfähigkeit der Wärmedämmelemente 10 liegt im Bereich 0,020 W/(m·K) bis 0,030 W/(m·K).The thermal insulation elements 10 have a homogeneous density. A density of the insulating material 12, which forms the insulating elements 10, is 32 kg / m 3 . A thermal conductivity of the thermal insulation elements 10 is in the range 0.020 W / (m · K) to 0.030 W / (m · K).

Eine Länge L der Wärmedämmelemente 10 und eine Breite B der Wärmedämmelemente 10 sind jeweils wesentlich größer als eine Dicke D der Wärmedämmelemente 10. Eine erste Oberfläche 20 der Wärmedämmelemente 10 bildet eine Innenseite der Wärmedämmelemente 10 aus, deren Ausmessung durch die Länge L und die Breite B definiert ist und die der Hochhausfassade 16 zugewandt ist. Eine zweite Oberfläche 22 der Wärmedämmelemente 10 bildet eine Außenseite der Wärmedämmelemente 10 aus, die der Hochhausfassade 16 abgewandt ist. Unmittelbar benachbart angeordnete Wärmedämmplatten 10 grenzen jeweils an ihren Stirnseiten 34 aneinander.A length L of the thermal insulation elements 10 and a width B of the thermal insulation elements 10 are each substantially larger than a thickness D of the thermal insulation elements 10. A first surface 20 of the thermal insulation elements 10 forms an inside of the thermal insulation elements 10, the dimension of the length L and the width B. is defined and the high-rise facade 16 is facing. A second surface 22 of the thermal insulation elements 10 forms an outer side of the thermal insulation elements 10, which faces away from the high-rise facade 16. Immediately adjacent arranged thermal insulation panels 10 each border on their end faces 34 together.

Die Wärmedämmelemente 10 sind schwer entflammbar. Gemäß einer europäischen Norm sind die Wärmedämmelemente 10 in eine Brandschutzklasse B eingestuft. Sie erfüllen damit auch eine Brandschutzklasse E, die ebenfalls gemäß der europäischen Norm definiert ist.The thermal insulation elements 10 are flame retardant. According to a European standard, the thermal insulation elements 10 are classified in a fire protection class B. They thus also fulfill a fire protection class E, which is also defined in accordance with the European standard.

Die Wärmedämmelemente 10 sind gemäß EN ISO 9239-1 geprüft. Im Fall einer Brandeinwirkung karbonisiert der Dämmstoff 12, wodurch eine Sauerstoffzufuhr gestoppt wird. Der Dämmstoff 12 verhindert damit eine Brandausbreitung. Der Dämmstoff 12 ist somit nicht brennbar. Zudem ist er unter Brandeinwirkung nicht schmelzend. Außerdem ist der Dämmstoff unter Brandeinwirkung nicht brennend abtropfend. Der Dämmstoff 12 ist dabei insbesondere nicht-glimmend. Eine kurzzeitige Temperatureinwirkung kann dabei grundsätzlich zu einer chemischen Veränderung des Dämmstoffs 12 führen. Eine exotherme Oxidation, die zu einem Glimmen führt, wird durch chemische Eigenschaften des Dämmstoffs 12, und zwar insbesondere durch die Karbonisierung, verhindert.The thermal insulation elements 10 are tested in accordance with EN ISO 9239-1. In the event of a fire, the insulating material 12 carbonizes, whereby an oxygen supply is stopped. The insulating material 12 prevents fire spreading. The insulating material 12 is thus not flammable. In addition, it is not melting under the influence of fire. In addition, the insulation material under fire exposure is not burning dripping. The insulating material 12 is included especially non-smoldering. In principle, a short-term effect of temperature can lead to a chemical change of the insulating material 12. Exothermic oxidation which leads to smoldering is prevented by chemical properties of the insulating material 12, in particular by the carbonization.

Weiter ist der Dämmstoff temperaturstabil. Bei einer dauerhaften Temperatureinwirkung von ca. 60 Grad bis 70 Grad bleibt eine physikalische Struktur des Dämmstoffs im Wesentlichen erhalten. Insbesondere ein Volumen des Dämmstoffs verringert sich dabei nur unwesentlich, d.h. eine Schrumpfung unter einer Dauertemperaturbelastung von 60 Grad bis 70 Grad ist kleiner als 5 Prozent. Der Dämmstoff ist dabei hochtemperaturbeständig, d.h. für eine Dauertemperaturbelastung von ca. 110 Grad ohne wesentliche Änderung der physikalischen Struktur ausgelegt.Furthermore, the insulation material is temperature-stable. At a permanent temperature effect of about 60 degrees to 70 degrees, a physical structure of the insulating material is substantially retained. In particular, a volume of the insulating material is reduced only insignificantly, i. a shrinkage under a continuous temperature load of 60 degrees to 70 degrees is less than 5 percent. The insulating material is high temperature resistant, i. designed for a continuous temperature load of about 110 degrees without significant change in the physical structure.

Weiter umfasst das Hochhaus-Wärmedämm-Verbundsystem ein Putzsystem 18, das teilweise auf die der Hochhausfassade 16 abgewandten Oberfläche 22 der Wärmedämmelemente 10 aufgebracht ist (vgl. Figur 2). Das Putzsystem 18 weist einen Oberflächenputz 36 auf, der mittels eines im Wesentlichen anorganischen Putzmaterials 38 ausgebildet ist. In dem Putzmaterial 38, das wenigstens den Oberflächenputz 36 ausbildet, ist ein Anteil von anorganischen Verbindungen größer als ein Anteil von organischen Verbindungen. Das Putzmaterial 38 weist einen Anteil von organischen Verbindungen auf, der kleiner als 1 Prozent ist.Furthermore, the high-rise thermal insulation composite system includes a cleaning system 18, which is partially applied to the high-rise facade 16 facing away from surface 22 of the thermal insulation elements 10 (see. FIG. 2 ). The cleaning system 18 has a surface plaster 36, which is formed by means of a substantially inorganic cleaning material 38. In the cleaning material 38, which forms at least the surface plaster 36, a proportion of inorganic compounds is greater than a proportion of organic compounds. The cleaning material 38 has a content of organic compounds that is less than 1 percent.

Das Putzmaterial 38 des Oberflächenputzes 36 ist stoffschlüssig mit dem Dämmstoff 12 der Wärmedämmelemente 10 verbunden. Das Putzmaterial 38 bedeckt die Oberfläche 22 des Dämmmaterials, die der Hochhausfassade 16 abgewandt ist, im Wesentlichen vollständig. Der Oberflächenputz 36 ist zwischenträgerfrei direkt auf die Wärmedämmelemente 10 aufgebracht. Zur farblichen Gestaltung des Hochhauses ist eine Farbe des Oberflächenputzes 36 frei gestaltbar.The cleaning material 38 of the surface plaster 36 is materially connected to the insulating material 12 of the thermal insulation elements 10. The cleaning material 38 covers the surface 22 of the insulating material, which faces away from the high-rise facade 16, substantially completely. The surface plaster 36 is applied directly to the thermal insulation elements 10 without any support. For the color design of the skyscraper, a color of the surface plaster 36 can be freely designed.

Das Putzsystem 18 weist weiter einen Unterputz 40 auf, der zwischen der Hochhausfassade 16 und den Wärmedämmelementen 10 angeordnet ist. Der Unterputz 40 ist stoffschlüssig mit der Hochhausfassade 16 und den Wärmedämmelementen 10 verbunden. Mittels des Unterputzes 40 sind die Wärmedämmelemente 10 an der Hochhausfassade 16 befestigt. Der Unterputz 40 ist ebenfalls aus einem im Wesentlichen anorganischen Putzmaterial 42 ausgebildet. Die Wärmedämmelemente 10 sind wärmebrückenfrei mit der Hochhausfassade 16 verbunden. In einer nicht erfindungsgemäßen Ausgestaltung können anstelle des Unterputzes 40 auch andere Zwischenschichten verwendet werden, die die Wärmedämmelemente 10 wärmebrückenfrei mit der Hochhausfassade 16 verbinden.The cleaning system 18 further has a flush-mounted 40, which is arranged between the high-rise facade 16 and the thermal insulation elements 10. The flush 40 is cohesively connected to the high-rise facade 16 and the thermal insulation elements 10. By means of the flush 40, the thermal insulation elements 10 are attached to the high-rise facade 16. The flush 40 is also formed of a substantially inorganic cleaning material 42. The thermal insulation elements 10 are free of thermal bridges connected to the high-rise facade 16. In a non-inventive embodiment 40 other intermediate layers can be used instead of the flush, which connect the thermal insulation elements 10 free of thermal bridges with the high-rise facade 16.

Durch den Oberflächenputz 36 und den Unterputz 40 sind die Wärmedämmelemente 10 in das Putzsystem 18 eingebettet. Das Putzsystem 18 begrenzt die Wärmedämmelemente 10 an den beiden Oberflächen 20, 22, die die Innenseite und die Außenseite der Wärmedämmelemente 10 ausbilden. Das Hochhaus-WärmedämmVerbundsystem ist als ein Schichtsystem ausgebildet, bei dem der Dämmstoff 12 der Wärmedämmelemente 10 zwischen dem Oberflächenputz 36 und dem Unterputz 40 des Putzsystems 18 angeordnet ist. Durch die aneinander grenzenden Stirnseiten 34 bilden die Wärmedämmelemente 10 eine unterbrechungsfreie Zwischenschicht zwischen dem Unterputz 40 und dem Oberflächenputz 36 aus.By the surface plaster 36 and the flush 40, the thermal insulation elements 10 are embedded in the plaster system 18. The cleaning system 18 limits the thermal insulation elements 10 on the two surfaces 20, 22, which form the inside and the outside of the thermal insulation elements 10. The high-rise thermal insulation composite system is designed as a layer system in which the insulating material 12 of the thermal insulation elements 10 between the surface plaster 36 and the flush 40 of the cleaning system 18 is arranged. By the adjacent end faces 34 the thermal insulation elements 10 form an uninterrupted intermediate layer between the flush-mounted 40 and the surface plaster 36.
