Der Austausch von Luft bzw Feuchtigkeit zwischen dem an die Wand angrenzenden Innenraum des Gebäudes und dem das Gebäude umgebenden Außenbereich wird über jene Luftströmungen bewerkstelligt, die das geschoßhohe Fassadenelement durchströmen und aus diesem an dessen oberem Ende austreten Um diese Luftströmungen in Gang zu setzen bzw. aufrecht zu erhalten, müssen die mit den Hinterluftungsschächten in Verbindung stehenden Luftemtπttsöffnungen am unteren Ende des Fassadenelementes und die mit den Hinterluftungsschächten in Verbindung stehenden Luftaustπttsöffnungen am oberen Ende des Fassadenelementes stets offen gehalten werden Bei kaltem Wetter bπngen diese Luftströmungen kalte Außenluft in die Hmterlüftungsschachte und in die mit Mineralwolle gefüllten Kammern und verringern dabei die Wärmedämmung des Fassadenelementes Aus der JP 56-008 237 A ist es bekannt, Dammplatten, die aus emem geschlossenzelligen, expandierten Hartschaum hergestellte wurden, nachträglich zu perforieren und die perforierten Dammplatten für die W rmedämmung und Durchlüftung von Hauswanden einzusetzen, die in Standerbauweise emchtet werden und em in einzelne Felder unterteiltes, tragendes Rahmen- fachwerk besitzen. Die Felder sind jeweils von einem oberen und unteren horizontalen Querträger und zwei nebeneinander angeordneten vertikalen Ständern begrenzt und enthalten eine perforierte Dämmplatte als Füllung, an deren Außenseite zwei seichte Hinterlüftungsschächte vorgesehen sind, die von vertikalen Leisten seitlich und einem an diesen befestigten Putzträger samt Putzschicht nach außen begrenzt sind. Bei einer solchen Hauswand wird der Austausch von Luft bzw. Feuchtigkeit zwischen dem Innenraum des Hauses und dem dieses umgebenden Außenbereich über jene Luftströmungen bewerkstelligt, die die Löcher der Dämmplatte und die an deren Außenseite angeordneten, seichten Hinterlüftungsschächte durchströmen. Bei kaltem Wetter dringt kalte Außenluft ins Innere dieser Hauswand ein und verringert die Warmedammwirkung der perforierten Dämmplatte.From DE 34 31 876 AI is a storey-high, to be attached to the outside wall Nollwäπneschutz facade element made of rigid polystyrene foam, which contains three storey-high ventilation ventilation shafts and six of these separated by perforated partitions, storey-high and each filled with mineral wool, the back of the facade element hm open smd. The exchange of air or moisture between the interior of the building adjacent to the wall and the outside area surrounding the building is accomplished via those air currents which flow through the floor-to-ceiling facade element and exit from it at its upper end in order to start or maintain these air currents In order to maintain the air outlet openings in connection with the ventilation ducts at the lower end of the facade element and the air outlet openings in connection with the ventilation ducts at the upper end of the facade element, they must always be kept open. In cold weather, these air currents penetrate cold outside air into and into the ventilation ducts Mineral wool-filled chambers and thereby reduce the thermal insulation of the facade element From JP 56-008 237 A it is known to add dam panels, which were made from a closed-cell, expanded rigid foam perforate and use the perforated dam panels for the thermal insulation and ventilation of house walls, which are embossed in a stand construction and have a supporting frame divided into individual fields own truss. The fields are each bordered by an upper and lower horizontal cross member and two vertical stands arranged side by side and contain a perforated insulation panel as a filling, on the outside of which two shallow rear ventilation shafts are provided, which are attached to the side by vertical strips and a plaster base and plaster layer attached to the outside are limited. In such a house wall, the exchange of air or moisture between the interior of the house and the outside area surrounding it is accomplished via those air currents which flow through the holes in the insulation board and the shallow rear ventilation shafts arranged on the outside thereof. In cold weather, cold outside air penetrates the interior of this house wall and reduces the thermal insulation effect of the perforated insulation board.
Zusammenfassung der Erfindung: Aufgabe der Erfindung ist es, die Dämmung von Gebäudedecken oder Wänden zu verbessern, bei denen Dämmplatten aus Polystyrol-Hartschaum verwendet und an ihrer Ober- bzw. Außenseite mit einer zumindest einlagigen Abdeckschicht abgedeckt werden.SUMMARY OF THE INVENTION: The object of the invention is to improve the insulation of building ceilings or walls, in which insulating boards made of rigid polystyrene foam are used and are covered on their top and outside with an at least single-layer covering layer.
Zur Lösung dieser Aufgabe schlägt die Erfindung ein diffusionsoffenes Dämmsystem mit einer zumindest einlagigen Abdeckschicht vor, bei dem die Übertragung der Feuchte ausschließlich über Wasserdampfdiffusion und nicht über Luftströmungen erfolgt. Dieses diffusionsoffene Dämmsystem ist erfindungsgemäß dadurch gekennzeichnet, daß nachträglich perforierte Dammplatten vorgesehen sind, deren Perforierungen an beiden Seiten der Dämmplatte vollständig bzw. faßt vollständig abgedeckt sind, wobei die Summe der Querschnittsflächen der Perforierungen einer Dämmplatte 1% - 7,5% ihrer Plattenoberfläche entspricht und die Dämmplatte einen Wasserdampf- Diffusionswiderstandsfaktor besitzt, der zwischen 2 und 15 liegt. Beim erfindungsgemäßen Dämmsystem sind die perforierten Dammplatten an beiden Seiten jeweils durch eine Abdeckschicht abgedeckt, die auch die an der jeweiligen Seite der Dämmplatten ausmündenden Perforierungen abdeckt. Dadurch wird der Eintritt von Außenluft in die Perforierungen der Dämmplatten bzw. ein Luftstrom durch die Perforierungen hindurch verhindert, sodaß eine die Wärmedämmwirkung der Dämmplatten herabsetzende Durchlüftung der Dämmplatten ausgeschlossen ist. Der aus der darunterliegenden Decke bzw. Wand austretende Wasserdampf diffundiert durch das erfindungsgemäße Dämmsystem hindurch bis an die Außenseite der die perforierten Dämmplatten an ihrer Ober bzw. Außenseite abdeckenden Abdeckschicht.To achieve this object, the invention proposes a diffusion-open insulation system with an at least one-layer cover layer, in which the moisture is transmitted exclusively via water vapor diffusion and not via air currents. This diffusion-open insulation system is characterized according to the invention in that perforated dam panels are subsequently provided, the perforations of which are completely or completely covered on both sides of the insulation panel, the sum of the cross-sectional areas of the perforations of an insulation panel corresponding to 1% - 7.5% of their panel surface and the insulation board has a water vapor diffusion resistance factor that is between 2 and 15. In the insulation system according to the invention, the perforated dam panels are covered on both sides by a covering layer which also covers the perforations opening out on the respective side of the insulation panels. As a result, the entry of outside air into the perforations of the insulation boards or an air flow through the perforations is prevented, so that ventilation of the insulation boards which reduces the thermal insulation effect of the insulation boards is excluded. The water vapor emerging from the underlying ceiling or wall diffuses through the insulation system according to the invention to the outside of the covering layer covering the perforated insulation boards on its top or outside.
Die über die Oberseite der Dämmplatte verteilten und in diese nachträglich eingebrachten Perforierungen, die mit ihren Querschnittsflächen nur 1% - 7,5% der Plattenoberseite bedecken, setzen den sehr hohen Wasserdampf- Diffusionswiderstandsfaktor der Polystyrol-Hartschaum- platten auf ein Größe zwischen 2 und 15 herab, ohne die wesentlichen Eigenschaften der Polystyrol-Hartschaumplatten, wie die sehr geringe Wärmeleitfähigkeit, die sehr hohe Druckfestigkeit, die hohe Brandbeständigkeit etc., zu verändern.The perforations distributed over the top of the insulation board and subsequently introduced into it, which with their cross-sectional areas only cover 1% - 7.5% of the top of the board, set the very high water vapor diffusion resistance factor of the rigid polystyrene foam slabs down to a size between 2 and 15 without changing the essential properties of the polystyrene rigid foam sheets, such as the very low thermal conductivity, the very high pressure resistance, the high fire resistance etc.

Die nachträglich hergestellten Perforierungen können zwischen 0,5 mm und 4 mm breit und bis zu 15 Grad gegenüber der Flächennormalen geneigt sein. Nachstehend wird die Erfindung an Ausführungsbeispielen anhand der Zeichnungen näher erläutert.The insulation system according to the invention provides for the use of high-quality insulation boards made of rigid polystyrene foam, which, in conjunction with the subsequently produced perforations, whose total cross-sectional area accounts for 1% - 7.5% of the board surface, has a water vapor diffusion resistance factor between 2 and 15 exhibit. The subsequently created perforations can be between 0.5 mm and 4 mm wide and inclined up to 15 degrees with respect to the surface normal. The invention is explained in more detail below using exemplary embodiments with reference to the drawings.
