Abstract

1. A thermally insulated, ventilated roof with a pitch >=10 degrees, which comprises a carrier structure (2), a thermal insulation (3), a surface-water-repellant foil (7), a roof covering sub-structure (10; 8+9), a roof covering (11) and a soft layer (6) which is made of an open-pored, rot-proof, thermally insulating material and which adjoins the thermal insulation (3), characterised in that the space between the thermal insulation (3) and carrier structure (2) and the foil (7) is filled with the soft material layer (6), and that the thickness of the material layer (6) is designed in dependence upon predetermined climatic conditions and two-way water vapour diffusion in the event of the possible precipitation of water to at least completely compensate the water balance on an annual average.

Description

Die Erfindung betrifft ein wärmegedämmtes hinterlüftetes Dach mit einer Neigung=10°, nach dem Oberbegriff des Patentanspruches 1.The invention relates to a thermally insulated ventilated roof with an inclination = 10 °, according to the preamble of claim 1.

Bei geneigten, gedämmten Dächern kann in bestimmten Wetterlagen Tauwasser zwischen Wärmeschicht und Dachpfannen anfallen. Um Folgeschäden durch Wasseransammlungen zu vermeiden, wird der Zwischenraum belüftet, wobei die Luft an der Traufe durch Belüftungsöffnungen zugeführt und durch Entlüftungsöffnungen am First abgeleitet wird. In der Regel wird noch innerhalb des Zwischenraumes eine Unterspannbahn (Folie) angeordnet, die Staub abhalten und Oberflächenwasser-insbesondere während der Bauzeit-ableiten soll. Dieser Vorteil wurde aber mit dem Nachteil erkauft, daß zwei Hinterlüftungsebenen anzuordnen sind, deren konstruktive Ausführung besonders an den Endstellen schwierig ist, zumal die vergrößerten Endöffnungen die Gefahr des unerwünschten Eintrittes von Wasser, Schnee und Lebewesen erhöhen.With inclined, insulated roofs, condensation can occur between the heat layer and roof tiles in certain weather conditions. In order to avoid consequential damage due to water accumulation, the space in between is ventilated, with the air at the eaves being supplied through ventilation openings and discharged through ventilation openings on the ridge. As a rule, an underlay membrane (film) is arranged inside the space to keep out dust and to drain surface water, especially during the construction period. However, this advantage was bought with the disadvantage that two ventilation levels are to be arranged, the construction of which is particularly difficult at the end points, especially since the enlarged end openings increase the risk of undesired entry of water, snow and living organisms.

So ist beispielsweise aus der EP-A-0046 944 eine Dämmung geneigter Dächer bekannt, bei der auf den Dachsparren harte Schaumstoffplatten zur Wärmedämmung aufgelegt sind, wobei diese Platten an ihrer Oberseite mit einer wasserabweisenden, dampfdurchlässigen Folie abgedeckt sind. Zwecks zusätzlicher Schalldämmung ist an der Unterseite der Wärmedämmplatten eine weiche Schicht aus mineralischem Fasermaterial angeordnet, die jedoch zur Vermeidung der zweiten Hinterlüftungsebene zwischen Folie und Wärmedämmplatten nichts beizutragen vermögen.For example, EP-A-0046 944 discloses an insulation of sloping roofs in which hard foam panels for thermal insulation are placed on the rafters, these panels being covered on their upper side with a water-repellent, vapor-permeable film. For the purpose of additional sound insulation, a soft layer of mineral fiber material is arranged on the underside of the thermal insulation panels, which, however, cannot contribute to avoiding the second ventilation level between the film and thermal insulation panels.

Der Erfindung liegt die Aufgabe zugrunde, ein wärmegedämmtes hinterlüftetes Dach oben aufgezeigter Gattung anzugeben, bei dem trotz Hinterlüftung in nur einer Ebene keine Feuchtigkeitsschäden auftreten und zusätzlich der Schall gedämpft wird.The invention has for its object to provide a thermally insulated ventilated roof type shown above, in which no moisture damage occurs in spite of ventilation in one level and the sound is additionally damped.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Zwischenraum zwischen Wärmedämmung bzw. Tragkonstruktion und Folie mit einem offenporigen, unverrottbaren, wärmedämmenden Material ausgefüllt ist. Für den Fachmann ist es überraschen, daß entgegen der althergebrachten Meinung die Bedingung, nämlich daß der Diffusionswiderstand nach außen abnehmen muß, hier nicht erfüllt zu sein braucht, um ein einwandfreie funktionierendes Dach zu erzielen. Zusätzlich wird die Dicke der weichen Materialschicht in Anpassung an die Klimabedingungen gewählt, sodaß sich bei vorgegebenen Klimabedingungen und Vorliegen einer geringen Wasserdampfdiffusion der Wasserhaushalt im Jahresmittel ausgleicht, d.h. das im Winter angesammelte Wasser verdunstet wieder im Sommer. Infolge der Jahresdiffusion durch die Folie bleibt die Menge so klein, daß keine bauwerkschädlichen Wasseransammlungen auftreten.The object is achieved in that the space between thermal insulation or support structure and film is filled with an open-pore, rot-proof, heat-insulating material. It is surprising for the person skilled in the art that, contrary to traditional opinion, the condition, namely that the diffusion resistance has to decrease towards the outside, need not be fulfilled here in order to achieve a perfectly functioning roof. In addition, the thickness of the soft material layer is selected to adapt to the climatic conditions, so that given the given climatic conditions and low water vapor diffusion, the water balance is balanced out on an annual average, i.e. the water accumulated in winter evaporates again in summer. As a result of the annual diffusion through the film, the amount remains so small that no water accumulation harmful to the building occurs.

Durch die Schicht aus weichem Material wird die Schalldämpfung verbessert, was besonders vorteilhaft bei bewohnten Dachräumen ist.The layer of soft material improves sound absorption, which is particularly advantageous in occupied attics.

Zwar ist aus dem DE-GM 75 17 229 eine Polyethylen-Dampfsperrfolie bekannt, an deren Unterseite sich eine aufkaschierte Auspeich- bzw. Schutzschicht befindet. Diese weiche Schaumstoff-Schutzschicht dient jedoch lediglich dazu, mechanische Beschädigungen zu vermeiden und nicht der Verhinderung von Feuchtigkeitsschäden wegen nicht ausreichender Hinterlüftung zwischen festen Wärmedämmplatten und Unterspannfolien.A polyethylene vapor barrier film is known from DE-GM 75 17 229, on the underside of which there is a laminated storage or protective layer. However, this soft foam protective layer only serves to avoid mechanical damage and not to prevent moisture damage due to insufficient ventilation between solid thermal insulation boards and underlay films.

Als weiterer Vorteil der Konstruktion ist noch zu nennen, daß er nur einer hinterlüftete Ebene gibt, deren Ein- und Ausgänge im Gegensatz zu den üblichen zwei übereinanderliegenden Lüftungsebenen konstruktiv problemlos zu beherrschen sind. Darüber hinaus ist es möglich, jede der Schichten in Mineralwolle und/oder Kunststoffschaum auszubilden.Another advantage of the construction is that it only gives one ventilated level, the entrances and exits of which, in contrast to the usual two superimposed ventilation levels, can be easily mastered. In addition, it is possible to form each of the layers in mineral wool and / or plastic foam.

In einer besonderen Ausführungsform besteht die Wärmedämmung aus einer durchgehenden Schicht mit einem Wämedurchgangskoeffizienten K≦0,45·W/m2K.In a special embodiment, the thermal insulation consists of a continuous layer with a heat transfer coefficient K ≦ 0.45 · W / m 2 K.

Der Vorteil dieser Konstruktion besteht darin, daß die Wärmedämmung in Form von Platten direkt auf den Sparren verlegt werden kann. Neben Mineralwolleplatten haben sich insbesondere Kunststoffhartschaumplatten aus Polystyrol oder Polyurethanschaum mit einer Stärke von 8-12 cm bewährt, wobei die diffusionsäquivalente Luftschichtdicke sd (DIN 4108 Teil 3) den Wert 9 m nicht unterschreiten sollte.The advantage of this construction is that the thermal insulation in the form of panels can be laid directly on the rafters. In addition to mineral wool panels, plastic foam panels made of polystyrene or polyurethane foam with a thickness of 8-12 cm have proven themselves, whereby the diffusion-equivalent air layer thickness s d (DIN 4108 Part 3) should not be less than 9 m.

In einer weiteren Ausführungsform besitzt die Folie aus Kunststoff mit einer Stärke von 10-30 µm und das Material aus Kunststoffschaum mit einer Stärke von 0,3-2,5 cm eine äquivalente Luftschichtdicke pd:-50,4 m.In a further embodiment, the film made of plastic with a thickness of 10-30 microns and the material made of plastic foam with a thickness of 0.3-2.5 cm has an equivalent air layer thickness pd: -50.4 m.

Bei hiesigen klimatischen Verhältnissen genügt die genannte äquivalente Luftschichtdicke Sd, so daß bei Normbedingung DIN 4108 im Winter überhaupt kein Tauwasser ausfällt und somit Wasserschäden im Dach von vorneherein vermieden werden. Als Kunststoffe haben sich besonders Polyurethane bewährt.Under local climatic conditions, the equivalent air layer thickness Sd is sufficient, so that under standard conditions DIN 4108 no condensation water fails at all in winter and water damage in the roof is thus avoided from the outset. Polyurethanes have proven particularly useful as plastics.

In einer weiteren Ausführungsform ist das Material direkt mit der als Bahn ausgebildeten Folie verbunden.In a further embodiment, the material is directly connected to the film designed as a web.

Als Bahnenware können Kunststoffolien mit oder ohne netzartige Bewehrung (Unterspannbahnen) verwendet werden, die schon in der Fabrik mit weichem Schaumstoff oder Mineralwolle versehen sind. Durch diese integrierten Produkte läßt sich die Verlegung wesentlich vereinfachen.Plastic sheeting with or without net-like reinforcement (underlay sheeting) can be used as sheeting, which is already provided with soft foam or mineral wool in the factory. These integrated products make it much easier to lay them.

Als Material können Glasfasern, Steinwolle und Kunststoffschäume verwendet werden. Insbesondere hat sich ein weichelastischer, offenzelliger Polyurethanschaum (Dichte 30-40 kg/m3, Stauhärte 3―4 kPa) auf Polyetherbasis bewährt, der gemäß den Auflagen der Baubehörde entsprechend der Brandschutzklasse B2 bzw. B1 nach DIN 4102 ausgerüstet sein kann.Glass fibers, rock wool and plastic foams can be used as the material. In particular, a flexible, open-celled polyurethane foam (density 30-40 kg / m 3 , accumulation hardness 3―4 kPa) on a polyether basis has proven itself, which can be equipped according to the requirements of the building authority according to fire protection class B2 or B1 according to DIN 4102.

Als Folie ist eine bedingt dampfdurchlässige Polyurethanfolie auf der Bais von hohen molekularen Polyhydroxyl-Verbindungen, Kettenverlängerungsmitteln und Polyisocyanaten geeignet. Bevorzugt sind thermoplastische Polyurethanelastomere, wie sie im Kunststoff-Handbuch Bd. 7,2 Aufl., 1983, auf den 428―440 beschrieben sind. Aus diesen Elastomeren können Folien durch Blasen und/oder Extrudieren von 8-50 um hergestellt werden. Weiter können Folien auch aus Polyurethan enthaltenden Lösungen bzw. Dispersionen hergestellt werden, wie sie z.B. auf den Seiten 562-580 des vorgenannten Kunststoff-Handbuches vorgestellt werden. Die Folien können eine poromere Struktur aufweisen.A conditionally vapor-permeable polyurethane film based on the base of high molecular weight polyhydroxyl compounds, chain extenders and polyisocyanates is suitable as the film. Thermoplastic polyurethane elastomers are preferred, as are described in the plastics handbook vol. 7.2 ed., 1983, on the 428-440. Films can be made from these elastomers by blowing and / or extruding 8-50 µm. Furthermore, foils can also be produced from solutions or dispersions containing polyurethane, as are presented, for example, on pages 562-580 of the aforementioned plastics manual. The films can have a poromeric structure.
