Die Erfindung beinhaltet eine Wärmedämmplatte aus Polystyrol (EPS/XPS) oder Polyurethan (PUR) mit niedriger Wasserdampfdiffusionszahl µ < 10 mit äußerer Beschichtung zur Ver­ besserung der mechanischen und weiterer physikalischer Eigenschaften der äußeren Plat­ tenoberfläche.The invention includes a thermal insulation board made of polystyrene (EPS / XPS) or polyurethane (PUR) with low water vapor diffusion number µ <10 with outer coating for ver improvement of the mechanical and other physical properties of the outer plat surface.

Die in der Patentanmeldung "Wärmedämmplatte aus Polystyrol (EPS/XPS) oder Polyurethan (PUR) mit niedriger Wasserdampfdiffusionszahl µ < 10" Aktenzeichen 100 07 774.9 be­ schriebene Wärmedämmplatte eignet sich auf Grund der niedrigen Wasserdampfdiffussions­ zahl µ sehr gut für die Dämmung von teilweise feuchtegefährdeten Gebäudeteilen, wie Wandsockeln zum Erdreich von Gebäuden bzw. zur Sanierung und Wärmedämmung von vorhandenen teilweise feuchtebelasteten Außenwänden. Die Verwendung dieser Wärme­ dämmplatten mit ihrer niedrigen Wasserdampfdiffussionszahl µ im vorher beschriebenen Anwendungsfall erfordert eine äußere Beschichtung in Form von Putz oder anderen mecha­ nisch schützenden Materialien. Diese äußeren Beschichtungen können sehr vielfältig sein und haben vielfach ungünstige Werte bezüglich der Wasserdampfdiffussion und stellen da­ mit den Vorteil der in der Patentanmeldung "Wärmedämmplatte aus Polystyrol (EPS/XPS) oder Polyurethan (PUR) mit niedriger Wasserdampfdiffusionszahl µ < 10" Aktenzeichen 100 07 774.9 beschriebenen Vorteile in Frage.The in the patent application "thermal insulation board made of polystyrene (EPS / XPS) or polyurethane (PUR) with a low water vapor diffusion number µ <10 "file number 100 07 774.9 be Written thermal insulation board is suitable due to the low water vapor diffusion number µ very good for the insulation of parts of the building that are at risk of moisture, such as Wall bases for the soil of buildings or for the renovation and thermal insulation of existing external walls that are partially exposed to moisture. The use of this heat insulation boards with their low water vapor diffusion number µ in the previously described Application requires an outer coating in the form of plaster or other mecha niche protective materials. These outer coatings can be very diverse and often have unfavorable values with regard to water vapor diffusion and are there with the advantage of the thermal insulation board made of polystyrene (EPS / XPS) or polyurethane (PUR) with a low water vapor diffusion number µ <10 "file number 100 07 774.9 described advantages in question.

Aufgabe der vorliegenden Erfindung ist es, den Vorteil der Wärmedämmplatte aus Polystyrol (EPS/XPS) oder Polyurethan (PUR) mit niedriger Wasserdampfdiffusionszahl µ < 10 durch eine geeignete äußere Beschichtung mit ebenfalls niedriger und angepaßter Wasserdampf­ diffusionszahl vorzuschlagen, die den mechanischen und sonstigen physikalischen Anforde­ rungen für die Verwendung als Wandplatte besonders für Wandsockel zum Erdreich von Gebäuden und bei der Sanierung von feuchtebelasteten Wänden gerecht wird.The object of the present invention is to take advantage of the thermal insulation board made of polystyrene (EPS / XPS) or polyurethane (PUR) with a low water vapor diffusion number µ <10 a suitable outer coating with also lower and adapted water vapor propose diffusion number that meets the mechanical and other physical requirements for use as a wall plate especially for wall plinths to the soil of Buildings and when renovating damp walls.

Diese Aufgabenstellung läßt sich mit dem neuen Baustoff, wie er in der Patentanmeldung PCT/EP 00/00635 des Erfinders beschrieben ist und auf dem Markt mit der Markenbezeich­ nung LETON vertrieben wird, realisieren. This task can be done with the new building material, as in the patent application PCT / EP 00/00635 of the inventor is described and on the market with the brand name LETON is sold.  

Dieser Baustoff besteht aus natürlichen mineralischen silikatischen Feinstbestandteilen, die eine niedrige Wasserdampfdiffussionszahl µ von < 10 gewährleisten sowie geringen Anteilen von Beimischungen, die dem Baustoff die erforderlichen mechanischen Eigenschaften für die Außenbeschichtung, wie hohe Festigkeit, besonders Abriebfestigkeit, Wasser- und Frost­ ständigkeit, geringes Quell- und Schwindmaß verleihen. Auf Grund seiner ausschließlichen mineralischen Zusammensetzung ist LETON in der Brandklasse A1 eingestuft.This building material consists of natural mineral silicate fine components that ensure a low water vapor diffusion number µ of <10 and small proportions of admixtures that give the building material the required mechanical properties for the External coating, such as high strength, particularly abrasion resistance, water and frost impart stability, low degree of swelling and shrinkage. Because of its exclusive mineral composition, LETON is classified in fire class A1.

Da aus dem Baustoff LETON Bauplatten, Spachtel, Putze und Mörtel hergestellt werden, ist eine Beschichtung der Wärmedämmplatten mit niedriger Wasserdampfdiffussionszahl µ als Putz, aber auch als fertig vom Werk aus beschichtete Verbundplatte möglich.Since LETON is used to make building boards, spatulas, plasters and mortars a coating of the thermal insulation boards with a low water vapor diffusion number µ as Plaster, but also possible as a composite panel coated from the factory.

Die Beschichtung als Verbundplatte im Werk hat den Vorteil geringer Arbeitskosten und ei­ ner hohen gleichmäßigen Qualität der Beschichtung durch dis industrielle Fertigung. Ein zu­ verlässiges Verfugen der Wand nach dem Einbau der Platten ist durch die Verwendung von Putzen, Spachtel bzw. Mörtel auf der gleichen Materialbasis gegeben. Die Elastizität und Schlagfestigkeit der LETON-Schicht kann durch das Einlegen von Fliesen und das Beimi­ schen von Fasern den jeweiligen Anforderungen angepaßt werden.Coating as a composite panel in the factory has the advantage of low labor costs and egg high uniform quality of the coating through industrial production. One too reliable grouting of the wall after the installation of the panels is possible by using Brush, filler or mortar on the same material basis. The elasticity and Impact resistance of the LETON layer can be achieved by inserting tiles and adding fibers are adapted to the respective requirements.

Die sichere Verbindung zwischen der dünnen LETON-Außenplatte und der Wärmedämm­ platte wird durch einen Spachtel aus LETON und die zusätzliche Verankerung des Spachtel in eingearbeitete Nuten auf der Oberfläche der gelochten EPS/PUR-Wärmedämmplatte er­ reicht.The secure connection between the thin LETON outer panel and the thermal insulation the board is made using a spatula made of LETON and the additional anchoring of the spatula in grooves on the surface of the perforated EPS / PUR thermal insulation board enough.

Wird der so vorgenommene Wandaufbau mit der diffussionsoffenen Wärmedämmung noch mit einer auf dem Markt verfügbaren diffusionsoffenen Außenwandfarbe beschichtet, ist ge­ währleistet, daß Wandfeuchte auf Grund des Dampfdruckes im Inneren der wärmeisolierten Wand über die beschichtete EPS/PUR-Wärmedämmplatte entweichen kann und somit die feuchte Wand über einen längeren Zeitraum austrocknet. Für die gewählte Außenfarbe ist wichtig, daß diese keine Feuchtigkeit über das diffussionsoffene Wärmedämmsystem von Außen in das Innere der wärmegedämmten Wand eindringen läßt.Is the wall construction made with the diffusion-open thermal insulation still coated with a diffusion-open exterior wall paint available on the market is ge ensures that wall moisture due to the vapor pressure inside the heat-insulated Wall can escape through the coated EPS / PUR thermal insulation panel and thus the damp wall dries out over a long period of time. For the selected exterior color is it is important that this no moisture over the diffusion-open thermal insulation system from Lets outside penetrate into the interior of the thermally insulated wall.

Bereits heute verfügbare Fassadenanstriche besitzten neben der für die durchgängige Dif­ fussionsoffenheit niedrige Wasserdampfdiffusionszahl µ < 10 weitere vorteilhafte Eigen­ schaften, wie wasserabweisend, und wärmereflektierend (z. B. die Außenanstrichfarbe LO­ TUS der ISPO GmbH oder Thermoshield-Exterieur der Firma Thermoshield GmbH) und ver­ bessern damit weiter die Einsatzmöglichkeiten der erfindungsgemäßen Lösung im Bauwe­ sen.Facade paints that are already available today have, in addition to that for continuous diff low water vapor diffusion number µ <10 further advantageous Eigen such as water-repellent and heat-reflecting (e.g. the exterior paint LO TUS from ISPO GmbH or Thermoshield exterior from Thermoshield GmbH) and ver thus further improve the possible uses of the solution according to the invention in construction sen.
