Description

Die Erfindung betrifft eine Unterspannbahn für geneigte Dächer, bestehend aus einer dampfdiffusionsoffenen, aber oberflächenwasserdichten Folie und einer Verstärkungsschicht.The invention relates to a sarking membrane for pitched roofs, consisting of a vapor diffusion-open but surface-water-tight film and a reinforcement layer.

Bei Dächern dringt unter bestimmten Wetterbedingungen Feuchtigkeit der Raumluft in die Wärmedämmung ein und kann, wenn diese aus Verschmutzungsgründen oder wegen der Ableitung des Oberflächenwassers von oben abgedeckt ist, durch Taupunktunterschreitung zu unerwünschten Durchfeuchtungen und damit teilweisem Verlust der wärmedämmenden Eigenschaften führen. Aus diesem Grunde war es bisher erforderlich, stets zwischen der Wärmedämmung und einer oberen Abdeckung einen Belüftungsraum freizulassen.Under certain weather conditions, roof air moisture penetrates into the thermal insulation and, if it is covered from above for reasons of pollution or due to the drainage of surface water, can lead to undesirable moisture penetration and thus a partial loss of the thermal insulation properties if the temperature falls below the dew point. For this reason it was previously necessary to always leave a ventilation space between the thermal insulation and an upper cover.

Aus der EP-A 0 046 944 ist eine Wärmedämmung eines Steildaches im Raum zwischen den Dachsparren bekannt, bei der die als Unterspannbahn dienenden Kaschierungsbahn nur eine geringe Wasserdampfdurchlässigkeit, d.h. einen hohen Wasserdampfdiffusionswiderstand aufweist.From EP-A 0 046 944 thermal insulation of a pitched roof in the space between the rafters is known, in which the liner sheet serving as the underlay has only a low water vapor permeability, i.e. has a high water vapor diffusion resistance.

Demgegenüber liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Unterspannbahn zu schaffen, die nur einen sehr geringen Wasserdampfdiffusionswiderstand aufweist, die aber dennoch oberflächenwasserdicht und sehr flexibel ist und sich den Unebenheiten des Daches bzw. der darunterliegenden Wärmedämmschicht gut anpaßt, trotzdem eine ausreichende Reißfestigkeit hat und insbesondere keinen Belüftungsraum zwischen Unterspannbahn und Dämmstoff erforderlich macht.In contrast, the present invention has for its object to provide a sarking membrane, which has only a very low water vapor diffusion resistance, but which is still surface waterproof and very flexible and adapts well to the unevenness of the roof or the underlying thermal insulation layer, nevertheless has sufficient tensile strength and, in particular, does not require any ventilation space between the underlay and insulation material.

Die Lösung dieser Aufgabe besteht erfindungsgemäß aus einer Folie sowie einer damit verbundenen Verstärkungsschicht aus einem offenporigen Weichschaumstoff und einer zwischen Weichschaumstoff und Folie angeordneten Armierung aus einem reißfesten Gittergewebe mit einer diffusionsäqυivalenten Luftschichtdicke von 0,07 - 0,12 mm.The solution to this problem consists according to the invention of a film and an associated reinforcing layer made of an open-pore soft foam and a reinforcement arranged between the soft foam and the film made of a tear-resistant mesh fabric with a diffusion-equivalent air layer thickness of 0.07-0.12 mm.

Durch die Einfügung einer derartigen Armierung ist es möglich, eine Dachbahn mit einer extrem dünnen Folie herzustellen, die sich trotz Regendichtheit durch hohe Wasserdampfdurchlässigkeit auszeichnet. Trotz günstiger Diffusionswerte ist die Unterspannbahn so fest, daß sie allen auf der Baustelle vorkommenden Beanspruchungen standhält. Durch den Schaumstoff wird darüberhinaus neben einer guten Anpassung an die baulich bedingten Unebenheiten des Daches eine zusätzliche Schalldämmung erzielt, was bei einer Auflage auf wärmedämmenden Kunststoffschaumplatten aus Styropor, Polyurethan oder ähnlichem besonders vorteilhaft ist.By inserting such reinforcement, it is possible to produce a roofing membrane with an extremely thin film, which is characterized by high water vapor permeability despite rainproofness. Despite favorable diffusion values, the underlay is so firm that it can withstand all the stresses that occur on the construction site. Through the foam, in addition to a good adaptation to the structural unevenness of the roof, additional sound insulation is achieved, which is particularly advantageous when placed on thermally insulating plastic foam panels made of polystyrene, polyurethane or the like.

Zweckmäßigerweise weist die Folie eine Dicke von 20 - 40 um, insbesondere 25 - 30 um auf und besteht aus Polyurethan. Dabei kann die Folie auch mit einer reflektierenden Oberfläche versehen sein, um Einstrahlungen zurückzuwerfen und damit die Dämmung des Daches noch weiter zu verbessern.The film expediently has a thickness of 20-40 μm, in particular 25-30 μm, and consists of polyurethane. The film can also be provided with a reflective surface in order to reflect back radiation and thus further improve the insulation of the roof.

Das Gittergewebe besteht zweckmäßigerweise aus Polyester und weist Filamente mit einem Durchmesser von 0,3 - 1 mm, insbesondere 0,5 - 0,8 mm, sowie eine Maschenweite von 6 - 20 mm, insbesondere 8 - 12 mm, auf.The mesh fabric expediently consists of polyester and has filaments with a diameter of 0.3-1 mm, in particular 0.5-0.8 mm, and a mesh size of 6-20 mm, in particular 8-12 mm.

Vorteilhafterweise weist die offenporige Weichschaumschicht aus Polyäther-Polyurethan eine Dicke von 2 - 12 mm, insbesondere 4 - 8 mm, auf.The open-pore soft foam layer made of polyether polyurethane advantageously has a thickness of 2-12 mm, in particular 4-8 mm.

Um eine gute Gesamtfestigkeit zu erhalten, kann die Folie im Bereich zwischen den Filamenten einer Masche des Gittergewebes mit dem Schaumstoff zumindest teilweise verbunden-sein. Besonders zweckmäßig ist es, wenn Weichschaumstoff, Gittergewebe und Folien durch Flammkaschieren miteinander verbunden sind.In order to obtain good overall strength, the film can be at least partially connected to the foam in the area between the filaments of a mesh of the mesh fabric. It is particularly expedient if soft foam, grid fabric and foils are connected to one another by flame lamination.

Die Unterspannbahn kann dann unmittelbar auf den Dachsparren und der Zwischensparrendämmung angeordnet und durch Konterlattung befestigt sein.The sarking membrane can then be arranged directly on the rafters and the intermediate rafter insulation and fastened by means of counter battens.

Bei einem sparrenoberseitigen Dämmsystem aus starren Dämmplatten kann die Unterspannbahn unmittelbar auf den Dämmplatten angeordnet werden.In the case of an insulation system made of rigid insulation boards on top of the rafters, the underlay can be arranged directly on the insulation boards.

Anhand einer schematischen Zeichnung sind Aufbau und Funktionsweise von Ausführungsbeispielen nach der Erfindung näher erläutert. Dabei zeigen

  • Fig. 1 die perspektivische Ansicht eines Abschnittes der Unterspannbahn in vergrößertem Maßstab und
  • Fig. 2 eine perspektivische Ansicht, teilweise geschnitten, der Anordnung der Unterspannbahn auf einem Steildach.
The structure and mode of operation of exemplary embodiments according to the invention are explained in more detail using a schematic drawing. Show
  • Fig. 1 is a perspective view of a portion of the sarking membrane on an enlarged scale and
  • Fig. 2 is a perspective view, partly in section, of the arrangement of the sarking membrane on a pitched roof.

Wie aus Fig. 1 zu ersehen ist, besteht die Unterspannbahn 1 praktisch aus drei Schichten, nämlich der Weichschaumschicht 2, dem Gittergewebe 3 mit den Filamenten 4 sowie der abdeckenden Folie 5.As can be seen from FIG. 1, the underlay 1 practically consists of three layers, namely the soft foam layer 2, the grid fabric 3 with the filaments 4 and the covering film 5.

Die Folie 5, die zweckmäßigerweise aus Polyurethan besteht, hat eine Dicke von 20 - 40 pm, insbesondere von 25 - 30 pm. Nach DIN 53455 beträgt die Reißdehnung 550 - 600 % und die Reißfestigkeit 50 - 75 N/mm2. Die Wasserdampfdurchlässigkeit - gemessen nach DIN 53122 - bei 38°C und 90% relativer Luftfeuchtigkeit beläuft sich bei einer 30 um starken Polyätherfolie auf 350 g/m2d bzw. bei einer entsprechenden Polyätherfolie auf 900 g/m2d. Gegen Oberflächenwasser ergab die Wasserdruckprüfung nach DIN 53886 Werte von über 1500 mm WS (entsprechend 165 mbar). Ferner kann die Folie mit brandhemmenden Zusatzstoffen ausgerüstet sein.The film 5, which expediently consists of polyurethane, has a thickness of 20-40 pm, in particular 25-30 pm. According to DIN 53455, the elongation at break is 550 - 600% and the tensile strength is 50 - 75 N / mm 2 . The water vapor permeability - measured according to DIN 53122 - at 38 ° C and 90% relative humidity amounts to 350 g / m 2 d with a 30 µm thick polyether film or to 900 g / m 2 d with a corresponding polyether film. Against surface water, the water pressure test according to DIN 53886 showed values of over 1500 mm WS (corresponding to 165 mbar). Furthermore, the film can be equipped with fire-retardant additives.

Die unterhalb der Folie 5 verlaufende Armierung 3 besteht aus einem Gittergewebe oder -gelege, das durch Wirken, Weben, Verflechten, Verknüpfen oder Koextrusion sich kreuzender Filamente 4 hergestellt werden kann und das mit festen oder losen Kreuzungspunkten ausgerüstet ist. Die Maschenweite beträgt 6 - 20 mm, insbesondere 8 - 12 mm. Die einzelnen Filamente 4 haben dabei eine Dicke von 0,3 - 1 mm, insbesondere 0,5 - 0,8 mm, wobei Kette oder Schuß, aber auch aus einzeln liegenden Fäden in Form von Bändchen mit einer Breite von 0,3 - 3 mm, insbesondere 0,5 - 1,5 mm ausgebildet sein können.The reinforcement 3 running below the film 5 consists of a lattice fabric or scrim, which can be produced by knitting, weaving, braiding, linking or coextrusion of intersecting filaments 4 and which is equipped with fixed or loose crossing points. The mesh size is 6 - 20 mm, especially 8 - 12 mm. The individual filaments 4 have a thickness of 0.3-1 mm, in particular 0.5-0.8 mm, with warp or weft, but also from individual threads in the form of tapes with a width of 0.3-3 mm, in particular 0.5-1.5 mm.

Als Schaumstoffbahn 2 werden vorteilhafterweise offenporige Polyäther-Polyurethan-Weichschaumstoffe mit 25 - 45 kg/m3, insbesondere 30 - 35 kg/m3 Rohdichte, und einer Dicke von 2 - 12 mm, insbesondere 4 - 8 mm, verwendet, die nach DIN 53571 eine Zugfestigkeit größer als 85 kPA besitzen. Die Luftdurchlässigkeit sollte 100 - 300 1/min 100 cm2, insbesondere 160 - 200 1/min 100 cm2 bei 10 mm Wassersäulendruck und 50 mm Probendicke betragen.Open-pore polyether polyurethane flexible foams having a bulk density of 25-45 kg / m 3 , in particular 30-35 kg / m 3 , and a thickness of 2-12 mm, in particular 4-8 mm, are advantageously used as the foam web 2, according to DIN 53571 have a tensile strength greater than 85 kPA. The air permeability should be 100 - 300 1 / min 100 cm 2 , in particular 160 - 200 1 / min 100 cm 2 at 10 mm water column pressure and 50 mm sample thickness.

Die drei Schichten, nämlich die Folie 5, das Gittergewebe 3 und cie Schaumstoffbahn 2, werden zweckmäßigerweise durch Flammkaschieren miteinander verbunden. Dadurch werden die Filamente 4 des Gittergewebes 3 teilweise in die Schaunstoffbahn 2 eingebettet und die Folien 5 vollflächig mit dem Schaumstoff und zumindest abschnittsweise mit den Filamenten 4 des Gittergewebes 3 verklebt. Damit wird euch die Reißfestigkeit der Unterspannbahn erhöht und ein Verzug durch Falten oder Wellen erschwert. Gleichzeitig wird die Diffusion des Wasserdampfes durch den ungestörten Übergangsbereich der Folien 5 zwischen Gittergewebe 3 und Schaumstoff 2 erleichtert.The three layers, namely the film 5, the lattice fabric 3 and the foam sheet 2, are expediently connected to one another by flame lamination. As a result, the filaments 4 of the lattice fabric 3 are partially embedded in the foam sheet 2 and the foils 5 are glued over the entire surface to the foam and at least in sections to the filaments 4 of the lattice fabric 3. This increases the tensile strength of the underlay and makes warping due to folding or waves more difficult. At the same time, the diffusion of the water vapor is facilitated by the undisturbed transition area of the foils 5 between the mesh fabric 3 and the foam 2.

Eine zusätzliche Erhöhung der Festigkeit ist dadurch möglich, daß die Folie 5 gereckt ist. Dies hat auch den Vorteil, daß bei Auftreten eines Feuers die Folie wegschrumpft und dadurch ein Weiterbrennen erschwert.An additional increase in strength is possible in that the film 5 is stretched. This also has the advantage that when a fire occurs, the film shrinks away, making it difficult to continue burning.

In gleicher Weise ist es auch möglich, die Filamente 4 des Sittergewebes oder -geleges 3 durch Recken in ihrer Festigkeit zu erhöhen.In the same way, it is also possible to increase the strength of the filaments 4 of the sitter fabric or scrim 3 by stretching.

Insgesamt kann durch eine spezielle Ausrüstung der drei Schhten der Unterspannbahn eine Schwerentflammbarkeit der Baustoffklasse Bl oder zumindest eine Baustoffklause 2 nach DIN 4102 erreicht werden.Overall, a special equipment of the three layers of the roofing membrane makes it possible to achieve fire resistance of building material class B1 or at least a building material class 2 according to DIN 4102.

In Fig. 2 ist nunmehr ein Anwendungsbeispiel der Unterspannbahn 1 auf einem Steildach näher erläutert. Dabei ist zunächst der Zwischenraum zwischen den Dachsparren 6 in voller Höhe mit Dämmstoff 7, beispielsweise aus einer Mineralwolle, ausgefüllt. Unterseitig kann dabei noch eite Kaschierung in Form einer Metallfolie 8 als Dampfspirre aufgebracht sein. Hierfür ist aber auch eine Schicht bzw. ein Material ausreichend, dessen diffusionsäquivalente Luftschichtdicke lediglich 2 m beträgt. Oberseitig ist nunmehr auf die Dachsparren 6 und unmittelbar auf den Dämmstoff 7 die erfindungsgemäße Unterspannbahn 1 aufgebracht. Diese Unterspannbahn 1 wird zweckmäßigerweise über eine Konterlattung 9 auf die Dachsparren 6 aufgenagelt. Es ist aber auch möglich, die Unterspannbahn 1 zunächst ohne Lattung 9 unmittelbar auf die Dachsparren 6 aufzunageln. Wegen des relativ engmaschigen Gittergewebes 3 werden dabei durch die im Dachhandwerk üblichen Klammern immer einzelne Filamente erfaßt, so daß sich eine schnelle und sichere Anbringung auch bei ungünstigen Wetterverhältnissen, wie beispielsweise einem stärkeren Wind, ohne weiteres möglich ist. Auf die Konterlattung 9 wird dann die eigentliche Lattung 10 aufgebracht, auf der die einzelnen Dachziegel 11 festgelegt werden.In Fig. 2 an application example of the sarking membrane 1 on a pitched roof is now explained in more detail. First, the space between the rafters 6 is filled in full with insulating material 7, for example made of mineral wool. On the underside, a lamination in the form of a metal foil 8 can also be applied as a vapor barrier. But there is also one for this Layer or a material sufficient, the diffusion-equivalent air layer thickness is only 2 m. The roofing membrane 1 according to the invention is now applied to the top of the rafters 6 and directly to the insulating material 7. This sarking membrane 1 is expediently nailed onto the rafters 6 by means of counter battens 9. But it is also possible to nail the roofing membrane 1 directly onto the rafters 6 without battens 9. Because of the relatively close-meshed lattice fabric 3, individual filaments are always detected by the clamps customary in roofing, so that a quick and secure attachment is possible without any problems even in unfavorable weather conditions, such as a stronger wind. The actual battens 10 are then applied to the counter battens 9, on which the individual roof tiles 11 are fixed.

Die Unterspannbahn 1 wird dabei zweckmäßigerweise reihenweise von unten nach oben traufparallel verlegt, wobei je nach Neigung des Daches eine entsprechende Überlappung zweckmäßig ist. Wegen der geringen Dampfbremswirkung der erfindungsgemäßen Unterspannbahn kann diese dann durchgehend über den First hinweg eingebaut werden.The sarking membrane 1 is expediently laid in rows from the bottom to the top of the eaves, a corresponding overlap being appropriate depending on the inclination of the roof. Because of the low vapor retarding effect of the roofing membrane according to the invention, it can then be installed continuously over the ridge.
