Definitions
- the invention relates to a foam sealing tape, for example for sealing between two building parts, in particular between a frame component and the masonry assigned to them, the sealing tape having opposite broad sides which can be assigned to the building parts and narrow sides running transversely to these, the sealing tape also from one of the narrow sides to the other to form a water vapor diffusion path permeable to water vapor diffusion and furthermore the sealing tape has a barrier layer made of a material different from the foam sealing tape material, which extends at least partially or completely over the cross section of the water vapor diffusion path.
- the barrier layer is usually arranged in the installed position of the sealing tape on the inside in order to provide the sealing tape according to the principle of "closer to the inside of the room than outside of the room” (referring to the water vapor diffusion resistance of the sealing tape), so that a corresponding diffusion gradient results due to the different water vapor diffusion resistances of the individual sealing tape areas and the water vapor entering the sealing tape on the inside can be removed from the sealing tape on the outside of the room.
- the barrier layer can be formed, for example, as a separate film or as a coating, reference is made, for example, to the EP 1 811 111 A1 . EP 2 309 090 A1 or DE 196 41 415 C2 or similar.
- the sealing tape is intended to fulfill its function determination in the case of different indoor climates as well as different weather conditions on the outside in relation to the removal of the water vapor to the outside of the room. Furthermore, it is to be avoided that moisture collects in the sealing tape area, for example on the structural part surfaces enclosing the sealing tape, but is discharged as water vapor via the sealing tape to the outside of the room. This is intended, for example, to prevent condensation on the component surfaces enclosing the sealing tape, which could lead to structural damage in the long run.
- conventional sealing tapes only meet these requirements to a limited extent.
- the barrier layer has only a comparatively low water vapor permeability, it can air humidity inside the room can only be removed to a very small extent via the sealing tape as water vapor. If, on the other hand, the barrier layer has a comparatively high water vapor permeability, there is a risk of condensation forming in the area of the sealing tape, in particular at very cold outside temperatures, and thus of damage to the masonry, frame component or the sealing tape.
- the invention has for its object to provide a foam sealing tape, which at least largely avoids moisture accumulation in the area of the sealing tape, even at low outside temperatures, but has sufficient water vapor permeability.
- the barrier layer consists at least partially of a material which reversibly changes its water vapor diffusion resistance (WDD resistance) with the air humidity (the barrier layer thus increases the WDD resistance to the foam material, but is still permeable to water vapor diffusion).
- WAD resistance water vapor diffusion resistance
- the barrier layer thus increases the WDD resistance to the foam material, but is still permeable to water vapor diffusion.
- water vapor can pass through the barrier layer and the sealing tape in a controlled manner depending on the air humidity. For example, if there is a relatively high level of humidity on the inside of the room, the water vapor diffusion resistance of the barrier layer can change, for example decrease, so that moisture inside the room diffuses more easily through the barrier layer and excessive room humidity can be avoided.
- the water vapor diffusion resistance (s D value) of the barrier layer increases, for example, and less water vapor passes through the barrier layer from the inside of the room.
- Moisture present in the sealing tape area for example on the component surfaces delimiting the sealing tape on its broad sides, can then be reliably removed via the sealing tape, since an additional application of water vapor to the sealing tape from the inside of the room is limited by the increase in the water vapor diffusion resistance of the barrier layer.
- the moisture that may accumulate on the building parts can relate, for example, to condensed water, but also to water absorbed in the masonry, for example in building parts made of porous material such as porous stone, aerated concrete or the like.
- the “broad side” is generally the sealing tape side, which is designed for contact with the components forming the joint or is provided as intended.
- the broad side generally (but not necessarily) has a greater width than the adjacent "narrow side". This can apply independently of one another for the completely relaxed state of the sealing tape or the arrangement within the joint, compression here being set as a reference point to 30% of the initial volume or the initial height of the completely relaxed sealing tape.
- the barrier layer preferably consists at least partially of a material which reduces its WDD resistance with increasing air humidity.
- a material which reduces its WDD resistance with increasing air humidity.
- the area of the barrier layer which consists of the material reversibly changing its WDD resistance with the humidity (rev. WDD material), is arranged partially or preferably completely through the water vapor diffusion path.
- the cross section of water vapor diffusion path is preferably predominantly, ie ⁇ 50 - 75% or ⁇ 80 - 90% or particularly preferably ⁇ 95% to 100%, cross-section of WDD material (possibly also ⁇ 20 - 35%). This can also correspond to the extent of the barrier layer across the sealing tape cross-section.
- the sealing tape-free cross section can correspond to ⁇ 1 - 2% or ⁇ 3 - 5% of the sealing tape cross section, if necessary also ⁇ 7 - 10% of the same.
- the rev. WDD material has a not too high WDD resistance
- the water vapor diffusion through the sealing tape is determined at least predominantly by the WDD resistance of the polymer material.
- the water vapor diffusion can essentially be determined by the permeability of the remaining web (or generally barrier-free area), so that in this way too, namely by properties of the barrier layer and its extension over the band width of the WDD resistance of the band is selectively adjustable.
- the WDD resistances of a barrier layer with different air humidities can be selected in such a way that in the case of air humidity with a low WDD resistance (e.g.
- the diffusion permeability of the barrier layer significantly (e.g. predominantly) through the barrier layer (with -) is determined, with high WDD resistance (e.g. at low air humidity) with the same barrier layer then the diffusion permeability to a greater extent, for example predominantly or practically completely through the barrier layer-free cross-sectional area of the sealing tape. This also allows the properties of the sealing tape to be specifically adjusted.
- the rev. WDD material preferably forms a layer of the barrier layer, preferably a continuous layer (hereinafter referred to as "barrier layer").
- the blocking position extends (possibly in combination with the above) over preferably ⁇ 30-40%, particularly preferably predominantly, ie ⁇ 50-75% or ⁇ 80-90%, particularly particularly preferably by ⁇ 95% to practically 100% across the sealing tape cross-section, based on the sealing tape cross-section at which the blocking position is located.
- This can relate to the maximum relaxed state of the sealing tape in the joint (that is, with even relaxation and complete filling of the joint) or the completely relaxed state of the sealing tape with free arrangement.
- the barrier layer is preferably designed as a continuous layer or film. This is preferably formed without openings through its surface extension, that is to say preferably impermeable to air with respect to flowing air or air pressure (under the measurement conditions for the a value according to DIN EN ISO 1026).
- openings can, however, be provided, which are optionally completely covered by a material which has a water vapor diffusion resistance that does not change with the atmospheric humidity, or can be water vapor diffusion-tight with only partial layers.
- This material can, for example, also be layer-shaped and be laminated with the position of the material with reversibly changing water vapor diffusion resistance or only fill the openings. In this way, for example, a minimum value of the water vapor diffusion resistance can be generated by the further layer with constant water vapor diffusion resistance, so that the sealing tape can be adapted to different requirements and environmental conditions.
- This further layer can consist, for example, of a plastic material, in particular an air-impermeable material (air-impermeable with respect to flowing air).
- the barrier layer particularly preferably has an s D value of 0.05 m to 100 m, preferably 0.1 m to 25 m or 0.2 m to 15 m (at 25% relative atmospheric humidity (rel. LF) , (the s D value is tested as is generally the case according to the invention in accordance with DIN EN ISO 12572) in order to be able to adequately control the water vapor diffusion.
- the s D value of the barrier layer is preferably 0,2 0.2-0.5 m or ⁇ 1 - 2 m, the s D value can be ⁇ 15-20 or ⁇ 5 - 10 m, in each case at 25% rel.LF, in particular the s D value can be in the range of 0.5 m - 20 m or Independent of this or in combination with this, the barrier layer can have an s D value of 0.02 m - 10 m or 0.03 m - 6 m or 0.05 m - 2 m at 72.5% rel LF, according to DIN EN ISO 12572.
- the sD values at 25% rel. LF in the range of 1 - 10m and at 72.5% rel. LF in the range of 0.1 - 5m EN ISO 12572 nothing else specifies the s D Values generally within the scope of the invention at a temperature of 20 ° C.
- the s D value (water vapor diffusion value based on an air layer thickness in meters) of the barrier layer at 25% on the one hand and at 72.5% relative air humidity on the other hand differs preferably by a factor of ⁇ 1.1 - 1, 2, preferably ⁇ 1.5-2, optionally up to a factor of 3 to 5 or to 10 to 20 or even to 50 or to 100 or 150 or more, as a result of which the dependence of the water vapor diffusion of the barrier layer on the air humidity is defined.
- the difference between the two s D values of the barrier layer at the two specified relative atmospheric humidities can be 0,2 0.25 m or 0,5 0.5 m or preferably 0,7 0.75-1 m, for example up to 5-10 m or up to 20 m 25 m or more.
- the s D value at 25% rel. Air humidity is preferably the higher value than that at 72.5% air humidity.
- the barrier layer preferably consists at least partially of a synthetic, water-swellable polymer as rev. WDD material.
- the barrier layer or a layer thereof particularly preferably exists at least partially from an ionomer material as rev. WDD material. It has been found that such ionomer materials mean that the WDD resistance of the barrier layer is sufficiently dependent on the WDD resistance on the air humidity, depending on the water vapor contents of the indoor climate normally occurring in the interior of buildings and / or in the atmospheric climate (outside of the room) has in order to achieve a sufficiently sensitive setting of the barrier effect in the usual changes in air humidity.
- such layers of ionomer material have sufficient flexibility and low bending stiffness, so that they can be folded sufficiently easily and relaxation of the foam material of the sealing tape from a compressed state (preferably automatic relaxation due to elastic restoring forces) has little or no effect Oppose resetting resistance, i.e. at least not significantly impair resetting (with regard to resetting time and / or resetting height).
- the rev. WDD materials can also be present as copolymers, for example in the form of a polyether copolymer with built-in ionomer components or a copolymer with polyethylene-polyacrylic acid copolymer components (in particular in the form of a polyether copolymer).

Description
Die Erfindung betrifft ein Schaumstoff-Dichtband, beispielsweise zur Abdichtung zwischen zwei Bauwerksteilen, insbesondere zwischen einem Rahmenbauteil und dem diesen zugeordneten Mauerwerk, wobei das Dichtband gegenüberliegende, den Bauwerksteilen zuordenbare Breitseiten und quer zu diesen verlaufende Schmalseiten aufweist, wobei das Dichtband ferner von einer der Schmalseiten zu der anderen hin unter Ausbildung eines Wasserdampfdiffusionspfades wasserdampfdiffusionsdurchlässig ausgebildet ist und wobei ferner das Dichtband eine Sperrschicht aus einem von dem Schaumstoff-Dichtbandmaterial verschiedenen Material aufweist, welches sich zumindest teilweise oder vollständig über den Querschnitt des Wasserdampfdiffusionspfades erstreckt.The invention relates to a foam sealing tape, for example for sealing between two building parts, in particular between a frame component and the masonry assigned to them, the sealing tape having opposite broad sides which can be assigned to the building parts and narrow sides running transversely to these, the sealing tape also from one of the narrow sides to the other to form a water vapor diffusion path permeable to water vapor diffusion and furthermore the sealing tape has a barrier layer made of a material different from the foam sealing tape material, which extends at least partially or completely over the cross section of the water vapor diffusion path.
Derartige Dichtungsbänder werden vielfältig eingesetzt, um Bauwerksfugen abzudichten. Die Sperrschicht ist hierbei zumeist in Einbaulage des Dichtbandes rauminnenseitig angeordnet, um das Dichtband nach dem Prinzip "rauminnenseitig dichter als raumaußenseitig" (Bezug nehmend auf den Wasserdampfdiffusionswiderstand des Dichtbandes) bereitzustellen, so dass sich aufgrund der unterschiedlichen Wasserdampfdiffusionswiderstände der einzelnen Dichtbandbereiche ein entsprechender Diffusionsgradient ergibt und der rauminnenseitig in das Dichtband eintretende Wasserdampf zur Raumaußenseite hin aus dem Dichtband abgeführt werden kann. Die Sperrschicht kann hierbei beispielsweise als separate Folie oder als Beschichtung ausgebildet sein, zu verweisen ist beispielsweise auf die
Das Dichtband soll seine Funktionsbestimmung bei unterschiedlichen Raumklimata im Innenraum als auch bei unterschiedlichen raumaußenseitigen Witterungsbedingungen in Bezug auf eine Abführung des Wasserdampfes zur Raumaußenseite hin erfüllen. Weiterhin soll vermieden werden, dass sich im Dichtbandbereich Feuchtigkeit ansammelt, beispielsweise an den das Dichtband einschließenden Bauwerksteilflächen, sondern als Wasserdampf über das Dichtband zur Raumaußenseite hin abgeführt wird. Hierdurch soll beispielsweise eine Kondenswasserbildung an den das Dichtband einschließenden Bauteilflächen vermieden werden, welche auf Dauer zu Bauwerksschäden führen könnte. Diesen Anforderungen werden herkömmlichen Dichtbänder jedoch nur bedingt gerecht. Weist beispielsweise die Sperrschicht eine nur vergleichsweise geringe Wasserdampfdurchlässigkeit auf, so kann auch rauminnenseitige Luftfeuchtigkeit nur in sehr geringem Umfang über das Dichtband als Wasserdampf abgeführt werden. Weist andererseits die Sperrschicht eine vergleichsweise hohe Wasserdampfdurchlässigkeit auf, so besteht insbesondere bei sehr kalten Außentemperaturen die Gefahr von Kondenswasserbildung im Bereich des Dichtbandes und damit von Schäden am Mauerwerk, Rahmenbauteil oder dem Dichtband.The sealing tape is intended to fulfill its function determination in the case of different indoor climates as well as different weather conditions on the outside in relation to the removal of the water vapor to the outside of the room. Furthermore, it is to be avoided that moisture collects in the sealing tape area, for example on the structural part surfaces enclosing the sealing tape, but is discharged as water vapor via the sealing tape to the outside of the room. This is intended, for example, to prevent condensation on the component surfaces enclosing the sealing tape, which could lead to structural damage in the long run. However, conventional sealing tapes only meet these requirements to a limited extent. If, for example, the barrier layer has only a comparatively low water vapor permeability, it can air humidity inside the room can only be removed to a very small extent via the sealing tape as water vapor. If, on the other hand, the barrier layer has a comparatively high water vapor permeability, there is a risk of condensation forming in the area of the sealing tape, in particular at very cold outside temperatures, and thus of damage to the masonry, frame component or the sealing tape.
Der Erfindung liegt die Aufgabe zugrunde, ein Schaumstoff-Dichtband bereitzustellen, welches eine Feuchtigkeitsansammlung im Bereich des Dichtbandes auch bei niedrigen Außentemperaturen zumindest weitestgehend vermeidet, jedoch eine ausreichende Wasserdampfdurchlässigkeit aufweist.The invention has for its object to provide a foam sealing tape, which at least largely avoids moisture accumulation in the area of the sealing tape, even at low outside temperatures, but has sufficient water vapor permeability.
Diese Aufgabe wird durch ein Dichtband nach Anspruch 1 gelöst. Erfindungsgemäß besteht die Sperrschicht zumindest teilweise aus einem seinen Wasserdampfdiffusionswiderstand (WDD-Widerstand) mit der Luftfeuchtigkeit reversible änderndem Material (die Sperrschicht erhöht also den WDD-Widerstand gegenüber dem Schaumstoffmaterial, ist hierbei aber immer noch wasserdampfdiffusionsdurchlässig). Hierdurch kann Wasserdampf die Sperrschicht und das Dichtband in Abhängigkeit von der Luftfeuchtigkeit gesteuert passieren. Liegt beispielsweise rauminnenseitig eine relativ hohe Luftfeuchtigkeit vor, kann sich der Wasserdampfdiffusionswiderstand der Sperrschicht ändern, beispielsweise verringern, so dass Feuchtigkeit im Rauminneren leichter durch die Sperrschicht nach außen diffundieren und eine zu hohe Raumluftfeuchtigkeit vermieden werden kann. Liegt rauminnenseitig - und damit auch an der Sperrschicht - eine relativ geringe Luftfeuchtigkeit vor, so erhöht sich beispielsweise der Wasserdampfdiffusionswiderstand (sD-Wert) der Sperrschicht, weniger Wasserdampf passiert von der Rauminnenseite her die Sperrschicht. Vorhandene Feuchtigkeit im Dichtbandbereich, beispielsweise an den das Dichtband an seinen Breitseiten begrenzenden Bauteilflächen, kann dann zuverlässig über das Dichtband abgeführt werden, da eine zusätzliche Beaufschlagung des Dichtbandes mit Wasserdampf von der Rauminnenseite her durch die Erhöhung des Wasserdampfdiffusionswiderstandes der Sperrschicht begrenzt wird. Die sich an den Bauwerksteilen möglicherweise ansammelnde Feuchtigkeit kann sich hierbei beispielsweise auf Kondenswasser beziehen, aber auch auf im Mauerwerk absorbiertes Wasser, beispielsweise bei Bauwerksteilen aus porösem Material wie porösem Gestein, Porenbeton oder dergleichen. Diese Änderungen der Luftfeuchtigkeit, welche eine geänderte Einstellung des sD-Wertes der Sperrschicht bedingen, können tageszeitabhängig eintreten (Änderung von Tag zu Nacht) oder witterungs- bzw. jahreszeitabhängig abhängig, so dass über einen gewissen Zeitraum eine Abfuhr der im Dichtbandbereich vorliegenden Feuchtigkeit durch die erfindungsgemäße Sperrschicht gewährleistet werden kann.This object is achieved by a sealing tape according to
Die "Breitseite" ist im Rahmen der Erfindung allgemein die Dichtbandseite, welche zur Anlage an die die Fuge ausbildenden Bauteile ausgebildet bzw. bestimmungsgemäß vorgesehen ist. Die Breitseite weist in der Regel (aber nicht zwingend) eine größere Breite auf, als die angrenzende "Schmalseite". Dies kann unabhängig voneinander gelten für den vollständig entspannten Zustand des Dichtbandes oder die Anordnung innerhalb der Fuge, wobei hier eine Kompression auf 30 % des Ausgangsvolumens bzw. der Ausgangshöhe des vollständig entspannten Dichtbandes als Bezugspunkt angesetzt wird.In the context of the invention, the “broad side” is generally the sealing tape side, which is designed for contact with the components forming the joint or is provided as intended. The broad side generally (but not necessarily) has a greater width than the adjacent "narrow side". This can apply independently of one another for the completely relaxed state of the sealing tape or the arrangement within the joint, compression here being set as a reference point to 30% of the initial volume or the initial height of the completely relaxed sealing tape.
Vorzugsweise besteht die Sperrschicht zumindest teilweise aus einem Material, welches mit zunehmender Luftfeuchtigkeit seinen WDD-Widerstand verringert. Hierdurch kann bei vergleichsweise hoher Luftfeuchtigkeit im Rauminneren eine unerwünschte Ansammlung von Luftfeuchtigkeit im Inneren des Dichtbandes oder an den an diesen angrenzenden Seitenflächen der Bauwerksteile verhindert und eine kontrollierte Abführung von Luftfeuchtigkeit durch Diffusion durch das Dichtband ermöglicht werden. Bei geringer Luftfeuchtigkeit im Rauminneren kann dann (verstärkt) Feuchtigkeit aus dem Dichtbandbereich, z. B. den an das Dichtband anliegenden Mauerwerksbereichen, abgeführt werden.The barrier layer preferably consists at least partially of a material which reduces its WDD resistance with increasing air humidity. In this way, in the case of comparatively high air humidity in the interior of the room, an undesired accumulation of air moisture inside the sealing tape or on the side faces of the building parts adjoining it can be prevented and a controlled removal of air moisture through diffusion through the sealing tape is made possible. With low air humidity inside the room, moisture from the sealing tape area, e.g. B. the masonry areas adjacent to the sealing tape.
Der Bereich der Sperrschicht, welcher aus dem reversibel seinen WDD-Widerstand mit der Luftfeuchtigkeit ändernden Material (rev. WDD-Material) besteht, ist den Wasserdampfdiffusionspfad teilweise oder vorzugsweise vollständig durchsetzend angeordnet. Durch das rev. WDD-Material wird der Wasserdampfdiffusionspfad vorzugsweise überwiegend, d. h. zu ≥ 50 - 75% oder ≥ 80 - 90% oder besonders bevorzugt ≥ 95 % bis zu 100 % in seinem Querschnitt durchsetzt (ggf. auch zu ≥ 20 - 35%). Dies kann jeweils auch der Erstreckung der Sperrschicht über den Dichtbandquerschnitt entsprechen. Der sperrschichtfreie Dichtbandquerschnitt kann ≥ 1 - 2 % oder ≥ 3 - 5 % des Dichtbandquerschnittes entsprechen, gegebenenfalls auch ≥ 7 - 10 % desselben. Bei nur unvollständiger Durchsetzung des Bandes mit der Sperrschicht kann gegebenenfalls, wenn das rev. WDD-Material einen nicht zu hohen WDD-Widerstand aufweist, die Wasserdampfdiffusion durch das Dichtband zumindest überwiegend durch den WDD-Widerstand des Polymermaterials bestimmt werden. Bei Auswahl eines rev. WDD-Materials mit vergleichsweise hohem WDD-Widerstand kann die Wasserdampfdiffusion im Wesentlichen durch die Durchlässigkeit des verbleibenden Steges (oder allgemein sperrschichtfreien Bereichs) bestimmt werden, so dass auch auf diese Weise, nämlich durch Eigenschaften der Sperrschicht und deren Erstreckung über den Bandquerstreckung der WDD-Widerstand des Bandes gezielt einstellbar ist. So können beispielsweise die WDD-Widerstände einer Sperrschicht bei unterschiedlichen Luftfeuchtigkeiten derart gewählt sein, dass bei der Luftfeuchtigkeit mit niedrigem WDD-Widerstand (z. B. hoher Luftfeuchtigkeit) die Diffusionsdurchlässigkeit der Sperrschicht wesentlich (z. B. überwiegend) durch die Sperrschicht (mit-)bestimmt wird, bei hohem WDD-Widerstand (z. B. bei niedriger Luftfeuchtigkeit) bei derselben Sperrschicht dann die Diffusionsdurchlässigkeit zu einem höheren Anteil, beispielsweise überwiegend oder praktisch vollständig durch den sperrschichtfreien Querschnittsbereich des Dichtbandes. Auch hierdurch sind die Eigenschaften des Dichtbandes gezielt einstellbar.The area of the barrier layer, which consists of the material reversibly changing its WDD resistance with the humidity (rev. WDD material), is arranged partially or preferably completely through the water vapor diffusion path. Through the rev. The cross section of water vapor diffusion path is preferably predominantly, ie ≥ 50 - 75% or ≥ 80 - 90% or particularly preferably ≥ 95% to 100%, cross-section of WDD material (possibly also ≥ 20 - 35%). This can also correspond to the extent of the barrier layer across the sealing tape cross-section. The sealing tape-free cross section can correspond to ≥ 1 - 2% or ≥ 3 - 5% of the sealing tape cross section, if necessary also ≥ 7 - 10% of the same. If the tape with the barrier layer is not fully enforced, the rev. WDD material has a not too high WDD resistance, the water vapor diffusion through the sealing tape is determined at least predominantly by the WDD resistance of the polymer material. When choosing a rev. WDD material with a comparatively high WDD resistance, the water vapor diffusion can essentially be determined by the permeability of the remaining web (or generally barrier-free area), so that in this way too, namely by properties of the barrier layer and its extension over the band width of the WDD resistance of the band is selectively adjustable. For example, the WDD resistances of a barrier layer with different air humidities can be selected in such a way that in the case of air humidity with a low WDD resistance (e.g. high air humidity) the diffusion permeability of the barrier layer significantly (e.g. predominantly) through the barrier layer (with -) is determined, with high WDD resistance (e.g. at low air humidity) with the same barrier layer then the diffusion permeability to a greater extent, for example predominantly or practically completely through the barrier layer-free cross-sectional area of the sealing tape. This also allows the properties of the sealing tape to be specifically adjusted.
Das rev. WDD-Material bildet vorzugsweise eine Lage der Sperrschicht aus, vorzugsweise eine durchgehende Lage (im Folgenden "Sperrlage" genannt).The rev. WDD material preferably forms a layer of the barrier layer, preferably a continuous layer (hereinafter referred to as "barrier layer").
Die Sperrlage erstreckt sich (ggf. in Kombination mit dem oben Gesagten) über vorzugsweise ≥ 30 - 40 %, besonders bevorzugt überwiegend, d. h. ≥ 50 - 75 % oder ≥ 80 - 90 %, insbesondere besonders bevorzugt um ≥ 95 % bis praktisch 100 % über den Dichtbandquerschnitt, bezogen auf den Dichtbandquerschnitt, an welchem sich die Sperrlage befindet. Dies kann sich jeweils auf den maximal entspannten Zustand des Dichtbandes in der Fuge (also bei gleichmäßiger Entspannung und vollständiger Ausfüllung der Fuge) oder den vollständig entspannten Zustand des Dichtbandes bei freier Anordnung beziehen.
Vorzugsweise ist die Sperrlage als durchgehende Schicht oder Folie ausgebildet. Diese ist vorzugsweise über deren Flächenerstreckung durchgehend ohne Durchbrechungen ausgebildet, also vorzugsweise in Bezug auf strömende Luft bzw. Luftdruck luftundurchlässig (unter den Messbedingungen für den a-Wert nach DIN EN ISO 1026). Gegebenenfalls können derartige Durchbrechungen jedoch vorgesehen sein, welche gegebenenfalls durch ein Material vorzugsweise vollständig überdeckt sind, welches einen sich mit der Luftfeuchtigkeit nicht ändernden Wasserdampfdiffusionswiderstand aufweist oder- bei nur teillagiger Erstreckung-wasserdampfdiffusionsdicht sein kann. Dieses Material kann beispielsweise ebenfalls schichtenförmig ausgebildet sein und mit der Lage des Materials mit sich reversibel änderndem Wasserdampfdiffusionswiderstand lamelliert sein oder lediglich die Durchbrechungen ausfüllen. Hierdurch kann beispielsweise ein Minimalwert des Wasserdampfdiffusionswiderstandes durch die weitere Schicht mit konstantem Wasserdampfdiffusionswiderstand erzeugt werden, so dass das Dichtband an unterschiedliche Erfordernisse und Umgebungsbedingungen anpassbar ist. Diese weitere Schicht kann beispielsweise aus einem Kunststoffmaterial bestehen, insbesondere einem luftundurchlässigen Material (luftundurchlässig in Bezug auf strömende Luft).The blocking position extends (possibly in combination with the above) over preferably ≥ 30-40%, particularly preferably predominantly, ie ≥ 50-75% or ≥ 80-90%, particularly particularly preferably by ≥ 95% to practically 100% across the sealing tape cross-section, based on the sealing tape cross-section at which the blocking position is located. This can relate to the maximum relaxed state of the sealing tape in the joint (that is, with even relaxation and complete filling of the joint) or the completely relaxed state of the sealing tape with free arrangement.
The barrier layer is preferably designed as a continuous layer or film. This is preferably formed without openings through its surface extension, that is to say preferably impermeable to air with respect to flowing air or air pressure (under the measurement conditions for the a value according to DIN EN ISO 1026). If necessary, such openings can, however, be provided, which are optionally completely covered by a material which has a water vapor diffusion resistance that does not change with the atmospheric humidity, or can be water vapor diffusion-tight with only partial layers. This material can, for example, also be layer-shaped and be laminated with the position of the material with reversibly changing water vapor diffusion resistance or only fill the openings. In this way, for example, a minimum value of the water vapor diffusion resistance can be generated by the further layer with constant water vapor diffusion resistance, so that the sealing tape can be adapted to different requirements and environmental conditions. This further layer can consist, for example, of a plastic material, in particular an air-impermeable material (air-impermeable with respect to flowing air).
Besonders bevorzugt weist die Sperrschicht einen sD-Wert von 0,05 m bis 100 m, vorzugsweise von 0,1 m bis 25 m oder von 0,2 m bis 15 m, auf (bei 25 % relativer Luftfeuchtigkeit (rel. LF), (die Prüfung des sD-Wertes erfolgt wie allgemein im Rahmen der Erfindung nach DIN EN ISO 12572), um die Wasserdampfdiffusion ausreichend steuern zu können. Der sD-Wert der Sperrschicht beträgt vorzugsweise ≥ 0,2 - 0,5 m oder ≥ 1 - 2 m, der sD-Wert kann ≤ 15-20 oder ≤ 5 - 10 m betragen, jeweils bei 25 % rel. LF, insbesondere kann der sD-Wert im Bereich von 0,5 m - 20 m oder 1 - 10 m liegen. Unabhängig hiervon oder in Kombination hiermit kann die Sperrschicht einen sD-Wert von 0,02 m - 10 m oder 0,03 m - 6 m oder 0,05 m - 2 m bei 72,5% rel. LF aufweisen, gemäß DIN EN ISO 12572. Beispielsweise kann der sD-Werte bei 25 % rel. LF im Bereich von 1 - 10m und bei 72,5 % rel. LF im Bereich von 0,1 - 5m liegen. Sofern nach DIN EN ISO 12572 nichts anderes bestimmt beziehen sich die sD-Werte allgemein im Rahmen der Erfindung auf eine Temperatur von 20°C.The barrier layer particularly preferably has an s D value of 0.05 m to 100 m, preferably 0.1 m to 25 m or 0.2 m to 15 m (at 25% relative atmospheric humidity (rel. LF) , (the s D value is tested as is generally the case according to the invention in accordance with DIN EN ISO 12572) in order to be able to adequately control the water vapor diffusion. The s D value of the barrier layer is preferably 0,2 0.2-0.5 m or ≥ 1 - 2 m, the s D value can be ≤ 15-20 or ≤ 5 - 10 m, in each case at 25% rel.LF, in particular the s D value can be in the range of 0.5 m - 20 m or Independent of this or in combination with this, the barrier layer can have an s D value of 0.02 m - 10 m or 0.03 m - 6 m or 0.05 m - 2 m at 72.5% rel LF, according to DIN EN ISO 12572. For example, the sD values at 25% rel. LF in the range of 1 - 10m and at 72.5% rel. LF in the range of 0.1 - 5m EN ISO 12572 nothing else specifies the s D Values generally within the scope of the invention at a temperature of 20 ° C.
Der sD-Wert (Wasserdampfdiffusionswert bezogen auf eine Luftschichtdicke in Metern) der Sperrschicht bei 25 % einerseits und bei 72,5 % relativer Luftfeuchtigkeit andererseits (jeweils bei 20°C) unterscheidet sich vorzugsweise um einen Faktor von ≥ 1,1 - 1,2, vorzugsweise ≥ 1,5 - 2, gegebenenfalls bis zu einem Faktor von 3 bis 5 oder bis 10 bis 20 oder auch bis 50 oder bis 100 oder 150 oder darüber hinaus, wodurch die Abhängigkeit der Wasserdampfdiffusion der Sperrschicht von der Luftfeuchtigkeit definiert wird. Die Differenz beider sD-Werte der Sperrschicht bei den beiden angegebenen relativen Luftfeuchtigkeiten kann ≥ 0,25 m oder ≥ 0,5 m oder vorzugsweise ≥ 0,75 - 1 m betragen, beispielsweise bis zu 5-10 m oder bis zu 20-25 m oder darüber hinaus. Hierdurch ergibt sich bei verschiedenen Umgebungsbedingungen, beispielsweise im Sommer oder Winter oder in unterschiedlichen Klimazonen, eine ausreichende Abhängigkeit des Wasserdampfdiffusionswiderstandes, um auch bei unterschiedlicher relativer Luftfeuchtigkeit der Umgebung eine ausreichende Anpassung des Wasserdampfdiffusionswiderstandes an die Umgebungsbedingungen zu erzielen. Der sD-Wert bei 25 % rel. Luftfeuchtigkeit ist hierbei vorzugsweise jeweils der höhere Wert gegenüber dem bei 72,5 % Luftfeuchtigkeit.The s D value (water vapor diffusion value based on an air layer thickness in meters) of the barrier layer at 25% on the one hand and at 72.5% relative air humidity on the other hand (each at 20 ° C) differs preferably by a factor of ≥ 1.1 - 1, 2, preferably ≥ 1.5-2, optionally up to a factor of 3 to 5 or to 10 to 20 or even to 50 or to 100 or 150 or more, as a result of which the dependence of the water vapor diffusion of the barrier layer on the air humidity is defined. The difference between the two s D values of the barrier layer at the two specified relative atmospheric humidities can be 0,2 0.25 m or 0,5 0.5 m or preferably 0,7 0.75-1 m, for example up to 5-10 m or up to 20 m 25 m or more. This results in a sufficient dependency of the water vapor diffusion resistance in various environmental conditions, for example in summer or winter or in different climatic zones, in order to achieve a sufficient adaptation of the water vapor diffusion resistance to the ambient conditions even with different relative atmospheric humidity. The s D value at 25% rel. Air humidity is preferably the higher value than that at 72.5% air humidity.
Vorzugsweise besteht die Sperrschicht zumindest teilweise aus einem synthetischen, wasserquellbaren Polymer als rev. WDD-Material.The barrier layer preferably consists at least partially of a synthetic, water-swellable polymer as rev. WDD material.
Besonders bevorzugt besteht die Sperrschicht oder eine Lage derselben zumindest teilweise aus einem lonomer-Material als rev. WDD-Material. Es hat sich herausgestellt, dass durch derartige lonomer-Materialien der WDD-Widerstand der Sperrschicht in Abhängigkeit von den üblicherweise auftretenden Wasserdampfgehalten des Raumklimas im Innenraum von Gebäuden und/oder im atmosphärischen Klima (raumaußenseitig) eine ausreichend hohe Abhängigkeit des WDD-Widerstandes von der Luftfeuchtigkeit aufweist, um bei den in der Praxis üblichen Änderungen der Luftfeuchtigkeit eine ausreichend empfindliche Einstellung der Sperrwirkung zu erzielen. Weiterhin weisen derartige Schichten aus lonomer-Material eine ausreichende Flexibilität und ausreichend geringe Biegesteifigkeit auf, so dass diese ausreichend leicht gefaltet werden können und einer Entspannung des Schaumstoffmaterials des Dichtbandes aus einem komprimierten Zustand (vorzugsweise einer selbsttätigen Entspannung aufgrund elastischer Rückstellkräfte) keinen oder einen nur geringen Rückstellwiderstand entgegensetzen, eine Rückstellung also zumindest nicht wesentlich beeinträchtigen (bzgl. Rückstellzeit und/oder Rückstellhöhe).The barrier layer or a layer thereof particularly preferably exists at least partially from an ionomer material as rev. WDD material. It has been found that such ionomer materials mean that the WDD resistance of the barrier layer is sufficiently dependent on the WDD resistance on the air humidity, depending on the water vapor contents of the indoor climate normally occurring in the interior of buildings and / or in the atmospheric climate (outside of the room) has in order to achieve a sufficiently sensitive setting of the barrier effect in the usual changes in air humidity. Furthermore, such layers of ionomer material have sufficient flexibility and low bending stiffness, so that they can be folded sufficiently easily and relaxation of the foam material of the sealing tape from a compressed state (preferably automatic relaxation due to elastic restoring forces) has little or no effect Oppose resetting resistance, i.e. at least not significantly impair resetting (with regard to resetting time and / or resetting height).
Nach einer anderen bevorzugten Ausführungsform besteht das rev. WDD-Material der Sperrschicht aus einem Polyamidmaterial oder aus EVOH (Ethylen-Vinylalkohol), auch wenn lonomer-Materialien zumeist bevorzugt sind, insbesondere im Hinblick auf die Empfindlichkeit des WDD-Widerstandes des Materials von der Luftfeuchtigkeit. Die rev. WDD-Materialien können auch als Copolymere vorliegen, beispielsweise in Form eines Polyether-Copolymers mit eingebauten lonomer-Bestandteilen oder einem Copolymer mit Polyethylen-Polyacrylsäure-Copolymer-Bestandteilen (insbesondere in Form eines Polyether-Copolymers). Das rev. WDD-Material kann auch aus Kombinationen der genannten Materialien bestehen.According to another preferred embodiment, the rev. WDD material of the barrier layer made of a polyamide material or of EVOH (ethylene vinyl alcohol), even if ionomer materials are mostly preferred, in particular with regard to the sensitivity of the material's WDD resistance to atmospheric humidity. The rev. WDD materials can also be present as copolymers, for example in the form of a polyether copolymer with built-in ionomer components or a copolymer with polyethylene-polyacrylic acid copolymer components (in particular in the form of a polyether copolymer). The rev. WDD material can also consist of combinations of the materials mentioned.
Derartige erfindungsgemäß einsetzbare Sperrschichtmaterialien mit feuchtigkeitsabhängigem Wasserdampfdiffusionswiderstand sind beispielsweise aus der
Unter "Ionomermaterial" sei ein polymeres Material verstanden, bei welchem das Polymermaterial ionische Gruppen aufweist, insbesondere Acrylat- oder Metacrylatgruppen, welche jeweils durch chemische Valenzbindungen mit Seitenketten oder dem Grundgerüst des polymeren Materials verbunden sind. Das Polymergerüst ist somit vorzugsweise negativ geladen. Die Gegenkationen zu dem Polymergerüst sind vorzugsweise ausgewählt aus der Gruppe Ammonium, Lithium, Natrium, Kalium, Magnesium, Calcium oder Zink oder Mischungen derselben, besonders bevorzugt Natrium und/oder Kalium, insbesondere bevorzugt Natrium.“Ionomer material” is understood to mean a polymeric material in which the polymeric material has ionic groups, in particular acrylate or methacrylate groups, which are each linked to side chains or to the basic structure of the polymeric material by chemical valence bonds. The polymer structure is thus preferably negatively charged. The counter cations to the polymer backbone are preferably selected from the Group ammonium, lithium, sodium, potassium, magnesium, calcium or zinc or mixtures thereof, particularly preferably sodium and / or potassium, particularly preferably sodium.

Besonders bevorzugt ist das lonomermaterial frei von Stickstoff bzw. enthält Stickstoff zu ≤ 3 - 5 Gew.-% oder ≤ 0,5 - 1 Gew.-%, vorzugsweise ≤ 0,1 - 0,25 Gew.-% bezogen auf die sich bei einer Verbrennung des Materials unter Sauerstoffüberschuss bei 300°C freisetzenden Komponenten (hierdurch soll abgegrenzt werden gegenüber Polyamid oder Polyurethanmaterialien, bei welchen sich ebenfalls der Wasserdampfdiffusionswiderstand mit der relativen Luftfeuchtigkeit ändert.The ionomeric material used preferably has no amide and / or urethane groups, which is ecologically preferred, for example when the material is disposed of by incineration, in relation to the UV resistance of the material and in relation to a more adjustable dependence of the water vapor diffusion resistance on the Moisture, which is preferred for many applications in relation to the sealing of the wall construction area. The ionomer material is particularly preferably free of nitrogen or contains nitrogen to 3 3 to 5% by weight or - 0.5 to 1% by weight, preferably 0,1 0.1 to 0.25% by weight, based on the when the material is burned under an excess of oxygen at 300 ° C-releasing components (this is to be differentiated from polyamide or polyurethane materials, in which the water vapor diffusion resistance also changes with the relative humidity).
Die Sperrlage aus dem rev. WDD-Material, insbesondere Ionomermaterial, kann eine Dicke von 1 µm bis 1 mm aufweisen, vorzugsweise eine Dicke von 1 - 500 µm oder 2 - 250 µm, besonders bevorzugt im Bereich von 5 - 100 µ oder 5 - 50 µ.The restricted area from the rev. WDD material, in particular ionomer material, can have a thickness of 1 μm to 1 mm, preferably a thickness of 1 to 500 μm or 2 to 250 μm, particularly preferably in the range from 5 to 100 μ or 5 to 50 μ.
Gegebenenfalls kann die lonomerschicht auch als flächenförmiger Tränkwerkstoff vorliegen in welchem die Menge der lonomere 1 - 500 g/m2, vorzugsweise 2 - 100 g/m2 beträgt.If appropriate, the ionomer layer can also be in the form of a sheet-like impregnation material in which the amount of ionomers is 1-500 g / m 2 , preferably 2-100 g / m 2 .
Die Sperrschicht kann mehrlagig, insbesondere eine mehrlagige Verbundschicht, sein. Ein- oder beidseitig der lonomerschicht bzw. der rev. WDD-Schicht kann jeweils zumindest eine Lage zumindest eines weiteren Materials angeordnet sein. Die eine oder beiden weiteren Lagen, welche die lonomerschicht oder allgemein die rev. WDD-Schicht jeweils teilweise oder vollständig bedecken, können die lonomer- bzw. rev. WDD-Schicht schützen und tragen bzw. unterstützen und die Stabilität der Sperrlage erhöhen, die einzelnen Lagen können jeweils aus gleichem oder verschiedenem Material bestehen, insbesondere beidseitig der lonomer- bzw. rev. WDD-Schicht. Die Sperrschicht hat jeweils vorzugsweise einen sD-Wert, welcher unter dem tiefsten sD-Wert der lonomerschicht bzw. rev. WDD-Schicht liegt. Gegebenenfalls können weitere Schichten aus wasserdampfdurchlässigem Gerüst- und/oder verarbeitungstechnischen Hilfsstoffen vorgesehen sein.The barrier layer can be multi-layer, in particular a multi-layer composite layer. One or both sides of the ionomer layer or the rev. WDD layer can be arranged at least one layer of at least one other material. The one or two further layers, which the ionomer layer or generally the rev. Partially or completely covering the WDD layer, the ionomer or rev. WDD layer protect and support or support and increase the stability of the barrier layer, the individual layers can each consist of the same or different material, in particular on both sides of the ionomer or rev. WDD layer. The barrier layer preferably has an s D value, which is below the lowest s D value of the ionomer layer or rev. WDD layer lies. If necessary, further layers of water vapor permeable framework and / or processing aids can be provided.
Die ein- oder beidseitig der lonomer- bzw. rev. WDD-Schicht angeordneten Lagen können insbesondere Vliese, Gewebe oder Gitter aus inerten Stoffen wie Polyethylen, Polypropylen, Polyester, Glasfasern oder Viskose sein, gegebenenfalls auch perforierte Folien, insbesondere solche aus Polyethylen, Polypropylen oder Polyester. Die Schichten können allgemein aus jedem geeigneten Material bestehen, welches in Schichtform vorliegt und vorzugsweise keine höheren sD-Werte hat als die lonomerschicht bzw. rev. WDD-Schicht.The one or both sides of the ionomer or rev. Layers arranged in the WDD layer can be, in particular, nonwovens, woven fabrics or grids made of inert substances such as polyethylene, polypropylene, polyester, glass fibers or viscose, optionally also perforated films, in particular those made of polyethylene, polypropylene or polyester. The layers can generally consist of any suitable material which is in layer form and preferably has no higher s D values than the ionomer layer or rev. WDD layer.
Das lonomermaterial kann als Abmischung (Blend oder Copolymer) mit anderen polymeren Materialien vorliegen wie Polyester, Polyamide, Vinylacetate usw., wie beispielsweise in der
Die Dicke der die lonomermaterialschicht bzw. rev. WDD-Schicht umgebenden Schichten der Sperrschicht können insgesamt je Seite unabhängig voneinander eine Dicke von 10 - 2.000 µm, vorzugsweise 10 - 500 µm, insbesondere 10 - 250 µm, besonders bevorzugt 10 - 90 µm betragen.The thickness of the ionomer material layer or rev. Layers of the barrier layer surrounding the WDD layer can have a total thickness of 10-2000 µm, preferably 10-500 µm, in particular 10-250 µm, particularly preferably 10-90 µm, independently of one another on each side.
Die lonomerschicht bzw. rev. WDD-Schicht bildet allgemein im Rahmen der Erfindung vorzugsweise eine durchgehend, nicht poröse und nicht-perforierte Schicht, besonders bevorzugt ist diese zumindest im Wesentlichen luftundurchlässig. Die Luftdurchlässigkeit der Sperrschicht bzw. Sperrlage kann ≤ 2 - 5 l/m2s oder vorzugsweise ≤ 0,5 -1 l/m2s oder ≤ 0,1 - 0,25 l/m2s oder besonders bevorzugt ≤ 0,01 -0,05 l/m2s nach DIN EN ISO 9237; Prüffläche 100 cm2 bei einem Messdruck (Unterdruck) von 0,5 mbar, Prüfgerät Frank 21443, betragen oder nicht messbar sein . Gegebenenfalls können diese Werte jeweils auch bei 2 mbar Unterdruck gelten. Die angegebene Norm und die Prüfbedingungen gelten für alle weiteren Messungen der Luftdurchlässigkeit soweit nicht anders angegeben. Die Sperrlage, insbesondere in Form einer luftundurchlässigen durchgehenden Schicht, kann die Reißfestigkeit und/oder Dehnbarkeit der Sperrschicht zumindest im Wesentlichen mitbestimmen (d. h. diese Lage für sich weist ≥ 50 - 75 % oder vorzugsweise ≥ 85 - 90 % der Reißfestigkeit und/oder des Elastizitätsmoduls der Sperrschicht insgesamt auf).The ionomer layer or rev. In general, WDD layer preferably forms a continuous, non-porous and non-perforated layer within the scope of the invention, particularly preferably this is at least essentially air-impermeable. The air permeability of the barrier layer or barrier layer can be 2 2-5 l / m 2 s or preferably 0,5 0.5-1 l / m 2 s or 0,1 0.1 - 0.25 l / m 2 s or particularly preferably 0 0, 01 -0.05 l / m 2 s according to DIN EN ISO 9237;
Die Luftdurchlässigkeit des den Dichtbandkorpus bildenden Schaumstoffmaterials liegt vorzugsweise im Bereich von 5 - 1.000 l/m2s oder 25 - 800 l/m2s, was sich in Kombination mit der Sperrschicht mit rev. WDD-Material als besonders geeignet in Hinblick auf die Diffusionseigenschaften erwiesen hat, vorzugsweise im Bereich von oder 50 - 600 l/m2s oder 100 - 450 l/m2s, gegebenenfalls auch bis zu 2000 l/m2s. Die jeweils angegebene Luftdurchlässigkeit bezieht sich auf die Normbedingungen (siehe oben) eines 10 mm dicken Schaumstückes (vollständig entspannt).The air permeability of the foam material forming the sealing tape body is preferably in the range from 5 to 1,000 l / m 2 s or 25 to 800 l / m 2 s, which in combination with the barrier layer with rev. WDD material has proven to be particularly suitable with regard to the diffusion properties, preferably in the range from or 50 to 600 l / m 2 s or 100 to 450 l / m 2 s, optionally also up to 2000 l / m 2 s. The air permeability specified relates to the standard conditions (see above) of a 10 mm thick piece of foam (completely relaxed).
Die Sperrlage kann auf unterschiedliche Weise an dem Dichtband angeordnet bzw. an diesem befestigt sein.The blocking position can be arranged on the sealing tape or fastened to it in different ways.
Nach einer besonders bevorzugten Ausführungsform ist die Sperrlage in einem Einschnitt des Schaumstoffmaterials angeordnet, so dass der innerhalb des Einschnittes angeordnete Bereich der Sperrlage also innerhalb des Querschnittes des Dichtbandes angeordnet ist. Die Sperrlage ist hierdurch innerhalb des Einschnittes von Beschädigungen durch äußere Eingriffe an das Dichtband geschützt. Weiterhin ist hierdurch die Sperrlage auf einfache Weise an dem Dichtband befestigbar. Insbesondere kann hierdurch auch die Lage der Sperrlage innerhalb der Fuge bei montiertem Dichtband entsprechend den jeweiligen Erfordernissen angepasst werden. So kann die Sperrlage beispielsweise von der rauminnenseitigen und raumaußenseitigen Seitenfläche des Dichtbandes beabstandet angeordnet sein, so dass die Außenseite des Dichtbandes nicht durch die Materialbeschaffenheit der Sperrlage beeinflusst wird. Andererseits kann die Sperrlage in einem gewünschten Querschnittsbereich des Dichtbandes angeordnet sein, beispielsweise im mittleren Bereich desselben oder aber auch benachbart der rauminnenseitigen Seitenfläche. Hierdurch kann die Wasserdampfdiffusionscharakteristik des Dichtbandes in Bezug auf die Fugentiefe eingestellt werden, insbesondere hinsichtlich einer Abführung von Wasserdampf von der Mauerwerkslaibung oder dergleichen. Der Einschnitt des Dichtbandes durchtrennt also das Dichtband nicht vollständig, sondern unter Verbleib eines verbindenden Schaumstoffsteges des Dichtbandes, welcher die beiden dem Einschnitt gegenüberliegenden Dichtbandbereiche einstückig miteinander verbindet. Hierdurch ist das Dichtband zudem einfach herstellbar, da ein Vorformling des Dichtbandschaumkörpers auf einfache Weise mit dem Einschnitt versehen und die Sperrschicht in diesen eingebracht werden kann, um das Dichtband herzustellen. Durch Schließen des Einschnittes ist die Sperrschicht an dem Dichtband vorfixiert. Eine Handhabung mit mehreren Schaumstoffkörpern, welche unter Erzeugung des Dichtbandes miteinander zu verbinden wären, ist hierdurch entbehrlich (auch wenn prinzipiell möglich). Weiterhin kann die Lage des Einschnittes auf vielfältige Weise variiert und den jeweiligen Erfordernissen angepasst werden. Zudem wirkt der verbleibende Dichtbandsteg bezgl. der Wasserdampfdiffusion als ein Art Bypass gegenüber der Sperrschicht, was bei bestimmten Gegebenheiten wie zeitweise sehr hoher Wasserdampfbeaufschlagung vorteilhaft sein kann.According to a particularly preferred embodiment, the blocking layer is arranged in an incision in the foam material, so that the region of the blocking layer arranged within the incision is therefore arranged within the cross section of the sealing tape. The blocking position is hereby protected from damage by external interventions on the sealing tape within the incision. Furthermore, the blocking position can thereby be fastened to the sealing tape in a simple manner. In particular, the position of the blocking position within the joint with the sealing tape installed can also be adapted to the respective requirements. For example, the blocking layer can be arranged at a distance from the inner and outer side surfaces of the sealing tape, so that the outside of the sealing tape is not influenced by the material properties of the blocking layer becomes. On the other hand, the blocking position can be arranged in a desired cross-sectional area of the sealing tape, for example in the central area thereof or also adjacent to the side surface inside the room. As a result, the water vapor diffusion characteristic of the sealing tape can be adjusted in relation to the joint depth, in particular with regard to the removal of water vapor from the masonry reveal or the like. The incision of the sealing tape thus does not completely cut through the sealing tape, but instead leaves a connecting foam web of the sealing tape, which integrally connects the two sealing tape areas opposite the incision. As a result, the sealing tape is also easy to produce, since a preform of the sealing tape foam body can be provided with the incision in a simple manner and the barrier layer can be introduced into it to produce the sealing tape. By closing the incision, the barrier layer is pre-fixed on the sealing tape. Handling with several foam bodies, which would have to be connected to one another while producing the sealing tape, is therefore unnecessary (even if in principle possible). Furthermore, the position of the incision can be varied in many ways and adapted to the respective requirements. In addition, the remaining sealing tape web acts as a kind of bypass with respect to the water vapor diffusion with respect to the barrier layer, which can be advantageous in certain circumstances, such as temporarily very high exposure to water vapor.
Der Einschnitt kann sich schräg zu der Normalen einer der Breitseiten des Schaumstoffbandes, z. B. in einem Winkel von ≤ ± 60° oder ≤ ± 45°, vorzugsweise ≤ ± 30° zu der Normalen erstrecken, oder zumindest im Wesentlichen senkrecht zu dieser, z. B. in einem Winkel ≤ ± 10 -15° oder ca. 0° zu dieser. Die Normale setzt hierbei am Beginn des Einschnittes (von der Dichtbandaußenseite her gesehen) an. Bei im Wesentlichen senkrechter Anordnung oder leichter Querneigung des Einschnittes ist die Sperrschicht zudem besonders einfach in den Einschnitt einbringbar, da hierzu das Dichtband kurvenförmig abgelegt werden kann, wobei der Einschnitt auf der Krümmungsaußenseite anzuordnen ist, so dass sich dieser durch die bogenförmige Biegung des Dichtbandes von alleine öffnet. Wird das Dichtband anschließend gestreckt angeordnet, schließt sich der Einschnitt wieder, unter Fixierung der Sperrschicht.The incision can be oblique to the normal of one of the broad sides of the foam tape, e.g. B. at an angle of ≤ ± 60 ° or ≤ ± 45 °, preferably ≤ ± 30 ° to the normal, or at least substantially perpendicular to this, z. B. at an angle ≤ ± 10 -15 ° or about 0 ° to this. The standard starts at the beginning of the incision (seen from the outside of the sealing tape). In the case of an essentially vertical arrangement or a slight transverse inclination of the incision, the barrier layer can also be introduced particularly easily into the incision, since the sealing tape can be deposited in a curved manner for this purpose, the incision being to be arranged on the outside of the curve so that it is separated by the arcuate bend of the sealing tape alone opens. If the sealing tape is then stretched, the incision closes again, fixing the barrier layer.
Allgemein im Rahmen der Erfindung kann die Sperrschicht durch Befestigungsmittel an dem Dichtband lagefixiert sein kann, beispielsweise durch einen Klebstoff, doppelseitiges Klebeband, geeignete Haftmittel, mechanische Mittel wie Vernähen, thermische Fixierung bei Anwesenheit von thermoplastischer Fixierungsmaterialien oder dergleichen.Generally within the scope of the invention, the barrier layer can be fixed in position by fastening means on the sealing tape, for example by an adhesive, double-sided adhesive tape, suitable adhesives, mechanical means such as sewing, thermal fixing in the presence of thermoplastic fixing materials or the like.
Vorzugsweise ist der Einschnitt an einer Breitseite des Schaumstoffbandes angebracht, so dass sich der Einschnitt im Wesentlichen entlang der Höhe des Dichtbandes (z. B. parallel zu den Seitenflächen) erstrecken kann. Der WDD-Widerstand des Dichtstreifens insgesamt kann somit durch die Sperrschicht einfach eingestellt werden.The incision is preferably made on a broad side of the foam tape, so that the incision can extend essentially along the height of the sealing tape (eg parallel to the side surfaces). The WDD resistance of the sealing strip as a whole can thus be easily adjusted by means of the barrier layer.
Gegebenenfalls kann der Einschnitt auch an einer Schmalseite des Dichtbandes angebracht sein. Hierdurch wird die Sperrschicht weniger in der ebenen Richtung der Schicht, sondern verstärkt in einer Richtung vertikal zur Lage druckbeaufschlagt, wenn das Dichtband vorkonfektioniert oder in der Fuge teilweise komprimiert ist. Die Sperrschicht kann hierdurch eine höhere Steifigkeit aufweisen, als bei der obigen Ausführungsform mit Erstreckung der Sperrschicht mit Einschnitt an der Breitseite.If necessary, the incision can also be made on a narrow side of the sealing tape. As a result, the barrier layer is pressurized less in the flat direction of the layer, but rather in a direction vertical to the position, when the sealing tape is pre-assembled or partially compressed in the joint. As a result, the barrier layer can have a higher rigidity than in the above embodiment with extension of the barrier layer with an incision on the broad side.
Alternativ oder gegebenenfalls in Kombination mit den weiteren Ausführungsformen im Rahmen der Erfindung, insbesondere jeweils mit den oben beschriebenen Ausführungsformen, kann die Sperrschicht in einer Durchtrennung des Schaumstoffkorpus angeordnet sein, so dass der Schaumstoffkorpus also zumindest zweiteilig ausgebildet ist. Die Durchtrennung kann sich insbesondere von Breitseite zu Breitseite oder von Schmalseite zu Schmalseite erstrecken oder auch von Eckbereich zu Eckbereich (diagonal) des Schaumstoffkorpus. Die Sperrschicht kann sich hier jeweils bezogen auf den Dichtbandquerschnitt vollständig über die Durchtrennung erstrecken oder nur über einen Teilbereich derselben unter Belassung eines sperrschichtfreien Bereichs des Dichtbandes.Alternatively or optionally in combination with the other embodiments within the scope of the invention, in particular in each case with the above-described embodiments, the barrier layer can be arranged in a cut through the foam body, so that the foam body is thus formed at least in two parts. The severing can extend in particular from broadside to broadside or from narrow side to narrow side or from corner area to corner area (diagonally) of the foam body. In relation to the sealing tape cross section, the barrier layer can here extend completely over the severing or only over a partial area thereof, leaving an area of the sealing tape free of a barrier layer.
Beispielsweise kann die Sperrschicht auch das Dichtband von Schmalseite zu Schmalseite vollständig durchsetzen, so dass der Schaumkörper des Dichtstreifens aus zwei Teilstücken zusammengesetzt sein kann.For example, the barrier layer can also completely penetrate the sealing tape from narrow side to narrow side, so that the foam body of the sealing strip can be composed of two parts.
Alternativ oder gegebenenfalls in Kombination mit den weiteren Ausführungsformen im Rahmen der Erfindung, insbesondere jeweils mit den oben beschriebenen Ausführungsformen, kann die Sperrschicht zumindest teilweise eine Seitenfläche des Dichtbandes überdecken, also außenseitig an dem Dichtband angeordnet sein, was fertigungstechnisch besonders einfach realisierbar ist. Die Sperrschicht kann sich hierbei über ≥ 20 - 30 % oder über den überwiegenden Teil der Dichtbandseitenfläche (d. h. ≥ 50 - 75 % oder ≥ 80 - 90 % oder besonders bevorzugt ≥ 95 - 100 %) erstrecken.Alternatively or optionally in combination with the other embodiments within the scope of the invention, in particular in each case with the above-described embodiments, the barrier layer can at least partially cover a side face of the sealing tape, that is to say be arranged on the outside of the sealing tape, which is particularly easy to implement in terms of production technology. The barrier layer can extend over ≥ 20-30% or over the major part of the sealing tape side surface (i.e. ≥ 50-75% or ≥ 80-90% or particularly preferably ≥ 95-100%).
Weiterhin kann jeweils ergänzend in Bezug auf die erfindungsgemäßen Ausführungsformen die Sperrschicht zusätzlich zumindest eine an die Seitenfläche angrenzende Breitseite des Dichtbandes teilweise oder vollständig überdecken. Hierdurch kann die Befestigung der Sperrschicht an dem Schaumstoffkörper verbessert werden, insbesondere auch, da die Breitseite bei Montageanordnung des Dichtbandes zwischen den benachbarten Fugenwänden druckbeaufschlagt ist.Furthermore, each can be supplementary with respect to the embodiments according to the invention the barrier layer additionally partially or completely cover at least one broad side of the sealing tape adjoining the side surface. As a result, the fastening of the barrier layer to the foam body can be improved, in particular also since the broad side is pressurized when the sealing tape is arranged between the adjacent joint walls.
Ist die Sperrschicht in einem Einschnitt des Dichtbandes angeordnet, so kann sich dieses auch teilweise außenseitig über die mit dem Einschnitt versehene Dichtbandseite erstrecken, beispielsweise die mit dem Einschnitt versehene Breitseite oder die mit dem Einschnitt versehene Schmalseite.If the barrier layer is arranged in an incision in the sealing tape, it can also extend partially on the outside over the sealing tape side provided with the incision, for example the broad side provided with the incision or the narrow side provided with the incision.
Der außenseitig an dem Dichtband angeordnete Sperrschichtabschnitt kann jeweils mit dem Dichtband verbunden werden, beispielsweise durch Anhaftung mittels einer Klebeschicht an dieses, so dass eine verbesserte Lagefixierung der Sperrschicht an dem Dichtband gegeben ist. Dies kann für den an einer Schmalseite und/oder an einer Breitseite des Dichtbandes (insbesondere letzteres) angeordneten Sperrschichtabschnitt gelten.The barrier layer section arranged on the outside on the sealing tape can in each case be connected to the sealing tape, for example by adhering to it by means of an adhesive layer, so that there is an improved fixing of the position of the barrier layer on the sealing tape. This can apply to the barrier layer section arranged on a narrow side and / or on a broad side of the sealing tape (in particular the latter).
Alternativ kann die Sperrschicht das Dichtband auch zumindest teilweise außenseitig überdecken. Die Sperrschicht kann hierbei Teil einer das Dichtband vollumfänglich umschließenden, vorzugsweise öffenbaren Umhüllung sein. Die Sperrschicht kann hierbei die öffenbare Umhüllung ausbilden, d. h. das Dichtband vollumfänglich umschließen, gegebenenfalls unter Verlängerung des Dichtbandes an der Verbindungsstelle der gegenüberliegenden Abschnitte der Sperrschicht, zwischen welchen das Dichtband eingeschlossen ist. Die Sperrschicht kann auch Teil einer mehrteiligen Umhüllung sein, beispielsweise Teil einer Umhüllungsfolie mit anderen Folienabschnitten als solchen aus der Sperrschicht, wobei diese anderen Abschnitte mit sich nicht reversibel änderndem Wasserdampfdiffusionswiderstand in Abhängigkeit von der Luftfeuchtigkeit insbesondere die jeweiligen Breitseiten des Dichtbandes überdecken können, gegebenenfalls zusätzlich auch die der Sperrschicht gegenüberliegende Schmalseite. Die Sperrschicht kann auch Teil einer Umhüllung sein, welche aus unterschiedlichen Abschnitten besteht, welche vorzugsweise jeweils in unterschiedlichen Umfangsabschnitten des Schaumstoffkörpers angeordnet sind. Die unterschiedlichen Umhüllungsabschnitte können aus unterschiedlichen Materialien und/oder unterschiedlichen Schichtdicken bestehen. So kann einer der Abschnitte der Befestigung des Dichtbandes an einem Bauwerksteil wie einem Rahmenteil ausgebildet sein oder eine andere Funktion aufweisen. Dieser Befestigungsbereich der Umhüllung kann eine höhere Steifigkeit aufweisen, als angrenzende Bereiche derselben, insbesondere als der die Sperrschicht umfassende Umhüllungsabschnitt. Der Schaumstoffkörper kann in der Umhüllung lagefixiert sein, beispielsweise durch eine Haftmittelschicht, welche vorzugsweise an einem Bereich der Umhüllung angeordnet ist, welcher die Sperrschicht nicht oder nur teilweise umfasst.Alternatively, the barrier layer can also at least partially cover the sealing tape on the outside. The barrier layer can in this case be part of a covering which preferably completely opens and surrounds the sealing tape. The barrier layer can form the openable covering, ie enclose the sealing tape over its entire circumference, possibly with the sealing tape being extended at the junction of the opposite sections of the barrier layer, between which the sealing tape is enclosed. The barrier layer can also be part of a multi-part wrapping, for example part of a wrapping film with film sections other than those from the barrier layer, these other sections being able to cover the respective broad sides of the sealing tape, in particular, if necessary, with non-reversibly changing water vapor diffusion resistance depending on the air humidity the narrow side opposite the barrier layer. The barrier layer can also be part of an envelope, which consists of different sections, which are preferably each arranged in different peripheral sections of the foam body. The different cladding sections can consist of different materials and / or different layer thicknesses. For example, one of the sections of the fastening of the sealing tape to a structural part such as a frame part can be designed or have another function. This fastening area of the casing can have a higher rigidity than adjacent areas thereof, in particular as the cladding section comprising the barrier layer. The foam body can be fixed in position in the covering, for example by means of an adhesive layer, which is preferably arranged on a region of the covering which does not or only partially surround the barrier layer.
Die die Seitenfläche zumindest teilweise überdeckende Sperrschicht kann auch sich zumindest teilweise über die beiden angrenzenden Breitseiten des Dichtbandes erstrecken und an zumindest einer oder beiden Breitseiten mit dem Schaumstoffkörper Zugkräfte aufnehmend verbunden sein. Gegebenenfalls kann die Sperrschicht auch entlang eines oder beider Längsränder mit einem weiteren Abschnitt eines anderen Materials verbunden sein, insbesondere eines Folienabschnittes, wobei der Folienabschnitt mit dem Schaumstoffkörper Zugkräfte aufnehmend verbunden ist.The barrier layer at least partially covering the side surface can also at least partially extend over the two adjacent broad sides of the sealing tape and can be connected to the foam body to absorb tensile forces on at least one or both broad sides. If appropriate, the barrier layer can also be connected along one or both longitudinal edges to a further section of another material, in particular a film section, the film section being connected to the foam body to absorb tensile forces.
Der außenseitig an dem Dichtband liegende Bereich der Sperrschicht kann von einem Befestigungsmittel wie z. B. einer Selbstklebeschicht überdeckt sein, mittels welcher beispielsweise das Dichtband an einem Bauteil oder Mauerwerk befestigbar ist, oder nur zur Fixierung der Sperrschicht an dem Dichtband. Die Überdeckungsseite kann insbesondere eine Dichtbandbreitseite sein.The outside of the sealing band area of the barrier layer can be fastened by a fastener such. B. a self-adhesive layer can be covered, by means of which, for example, the sealing tape can be fastened to a component or masonry, or only for fixing the barrier layer to the sealing tape. The overlap side can in particular be a sealing tape broadside.
Die Sperrschicht erstreckt sich im Rahmen der Erfindung im Allgemeinen in Längsrichtung des Dichtungsbandes, so dass sich die Längsränder der Sperrschicht vorzugsweise in Dichtbandlängsrichtung erstrecken, besonders bevorzugt parallel zu dieser.In the context of the invention, the barrier layer generally extends in the longitudinal direction of the sealing tape, so that the longitudinal edges of the barrier layer preferably extend in the longitudinal direction of the sealing tape, particularly preferably parallel to it.
Das Dichtband kann in einem komprimierten Zustand vorliegen, beispielsweise im vorkonfektionierten Zustand oder in Einbaulage der Fuge, vor dessen Rückstellung. Umgibt die Sperrlage das Dichtband außenseitig, ist vorzugsweise eine Dehnungsreserve der Außenumhüllung vorgesehen, welche die Sperrschicht umfassen kann. Die Dehnungsreserve kann beispielsweise in Form einer Faltelung ausgebildet sein. Die Dehnungsreserve bedingt, dass der komprimierte Schaumstoffkörper des Dichtbandes sich im Volumen vergrößern kann, ohne dass die Umhüllung einer Dehnung ausgesetzt wird. Bei dem erfindungsgemäßen Dichtband kann nach einer bevorzugten Ausführungsform die Sperrschicht mit der Dehnungsreserve versehen sein, wozu die Sperrschicht eine ausreichende Biegeschlaffheit aufweist. Hierdurch kann die Sperrschicht mehrere Funktionen in sich vereinen. Nach einer anderen bevorzugten Ausführungsform ist die Dehnungsreserve in einem Bereich der Umhüllung vorgesehen, welcher von der Sperrschicht verschieden ist. Hierdurch können Sperrschicht und Dehnungsreserve unabhängig voneinander optimal an die jeweiligen Erfordernisse angepasst werden, beispielsweise hinsichtlich der Sperrwirkung einerseits und der Flexibilität der Dehnreserve andererseits.The sealing tape can be in a compressed state, for example in the pre-assembled state or in the installed position of the joint, before it is reset. If the barrier layer surrounds the sealing tape on the outside, an expansion reserve of the outer covering is preferably provided, which may include the barrier layer. The expansion reserve can be designed, for example, in the form of a fold. The expansion reserve means that the compressed foam body of the sealing tape can increase in volume without exposing the casing to expansion. In the sealing tape according to the invention, according to a preferred embodiment, the barrier layer can be provided with the expansion reserve, for which purpose the barrier layer has sufficient bending slack. As a result, the barrier layer can combine several functions. According to another preferred embodiment, the expansion reserve is provided in an area of the envelope which is different from the barrier layer. This can create a barrier layer and the expansion reserve can be optimally adapted to the respective requirements independently of one another, for example with regard to the locking effect on the one hand and the flexibility of the expansion reserve on the other.
Nach einer bevorzugten Abwandlung kann das Dichtband verschiedene Sperrlagen mit unterschiedlicher reversibler Abhängigkeit des Wasserdampfdiffusionswiderstandes von der Luftfeuchtigkeit aufweisen. Diese Sperrlagen können bei unterschiedlichen Luftfeuchtigkeiten der Umgebung eine Abhängigkeit des Wasserdampfdiffusionswiderstandes von der Luftfeuchtigkeit aufweisen, also beispielsweise eine der Sperrschichten bei vergleichsweise niedriger Luftfeuchtigkeit und die andere Sperrschicht bei vergleichsweise hoher Luftfeuchtigkeit. Alternativ oder zusätzlich können die beiden Sperrschichten unterschiedlich starke Abhängigkeiten des Wasserdampfdiffusionswiderstandes von der Luftfeuchtigkeit aufweisen (d. h. unterschiedliche Empfindlichkeiten), beispielsweise um ≥ den Faktor 1,1 bis 1,2 oder ≥ 1,5 bis 2 oder vorzugsweise ≥ 3 bis 5 oder auch ≥ 10. Der Unterschied der Empfindlichkeit kann ≤ 500 - 1.000 oder ≤ 100 - 250 sein, insbesondere auch ≤ 50 - 75 oder ≤ 10 - 20, gegebenenfalls auch ≤ 5 - 7. Dies bezieht sich jeweils auf Raumtemperatur (20°C). Der Unterschied der Empfindlichkeit kann insbesondere bei einer relativen Luftfeuchtigkeit von 50 % bei 20°C bestimmt sein. Beispielsweise kann die Sperrschicht mit vergleichsweise großem WDD-Widerstand rauminnenseitig angeordnet sein und die mit kleinem WDD-Widerstand raumaußenseitig. Beispielsweise kann die Sperrschicht mit vergleichsweise großer Abhängigkeit des WDD-Widerstandes von der relativen Luftfeuchtigkeit rauminnenseitig und die Sperrschicht mit relativ kleiner Abhängigkeit raumaußenseitg angeordnet sein.According to a preferred modification, the sealing tape can have different barrier layers with different reversible dependencies of the water vapor diffusion resistance on the air humidity. In the case of different atmospheric humidities in the environment, these barrier layers can have a dependence of the water vapor diffusion resistance on the atmospheric humidity, that is to say, for example, one of the barrier layers when the humidity is comparatively low and the other barrier layer when the humidity is comparatively high. Alternatively or additionally, the two barrier layers can have dependencies of the water vapor diffusion resistance on the air humidity of different strengths (ie different sensitivities), for example by ≥ the factor 1.1 to 1.2 or ≥ 1.5 to 2 or preferably ≥ 3 to 5 or also ≥ 10. The difference in sensitivity can be ≤ 500 - 1,000 or ≤ 100 - 250, in particular also ≤ 50 - 75 or ≤ 10 - 20, possibly also ≤ 5 - 7. This refers to room temperature (20 ° C). The difference in sensitivity can be determined in particular at a relative humidity of 50% at 20 ° C. For example, the barrier layer with a comparatively large WDD resistance can be arranged on the inside and that with a small WDD resistance on the outside. For example, the barrier layer with a comparatively large dependence of the WDD resistance on the relative air humidity can be arranged on the inside of the room and the barrier layer with a relatively small dependency on the outside of the room.
Weiterhin von der Erfindung umfasst ist ein Wandaufbau mit einem in einer Fuge angeordneten Dichtband gemäß der Erfindung, wobei das Dichtband vorzugsweise derart in der Fuge angeordnet ist, dass die Sperrlage in Bezug auf die Mittelebene des Dichtbandes (Anordnung der Mittelebene zwischen rauminnenseitiger und raumaußenseitiger Seitenfläche des Dichtbandes) rauminnenseitig gerichtet in der Fuge angeordnet ist. Vorzugsweise ist die Sperrlage an der rauminnenseitigen Seitenfläche des Dichtbandes angeordnet oder in einem Erstreckungsbereich von ≤ 25 -33 % oder ≤ 10 - 20 % in Bezug auf die Breitenerstreckung des Dichtbandes (Erstreckung des Dichtbandes in der Fugentiefe). Hierdurch kann eine funktionsgerechte Abführung von Luftfeuchtigkeit aus dem Dichtband zur raumaußenseitigen Umgebung hin erfolgen.Also included in the invention is a wall structure with a sealing tape arranged in a joint according to the invention, the sealing tape preferably being arranged in the joint in such a way that the blocking position with respect to the central plane of the sealing tape (arrangement of the central plane between the inside and outside surfaces of the room Sealing tape) is arranged inside the joint in the room. The blocking position is preferably arranged on the side surface of the sealing tape on the inside of the room or in an extension range of 25 25 -33% or 10 10-20% in relation to the width of the sealing tape (extension of the sealing tape in the joint depth). In this way, a functional removal of air moisture from the sealing tape to the outside of the room can take place.
Insbesondere kann der Wandaufbau Teil eines Passivhauses oder einer Vollwärmeschutzwand sein, wo sich die mit der der Erfindung zugrunde liegenden Aufgabenstellung ergebenden Probleme in besonderem Umfang ergeben.In particular, the wall structure can be part of a passive house or a full heat protection wall be where the problems arising from the problem underlying the invention arise to a particular extent.
Vorzugsweise ist das Dichtband derart in der Fuge zwischen einem Rahmenbauteil und der angrenzenden Mauerwerkslaibung angeordnet, dass sich das Dichtband über die gesamte Tiefe (rauminnenseitig zu raumaußenseitig) des Abdichtungsbereiches zwischen Rahmenbauteil und Laibung erstreckt. Gegebenenfalls ist jedoch auch nur eine Teilerstreckung möglich, unter Heranziehung weiterer Dichtungsmaterialien.The sealing tape is preferably arranged in the joint between a frame component and the adjacent masonry reveal that the sealing tape extends over the entire depth (inside the room to the outside of the room) of the sealing area between the frame component and the reveal. If necessary, however, only a partial extension is possible, using other sealing materials.

Die Sperrschicht hat nach dem Ausführungsbeispiel einen SD-Wert von 0,1 m bis 20 m, im speziellen von 5 - 10 m, bei 25 % rel. LF. Die Sperrschicht weist bei einer relativen Luftfeuchtigkeit von 72,5 % einen um den Faktor ≥ 1,1, im Speziellen ca. den Faktor 5 - 10, kleineren WDD-Widerstand auf, als bei einer Luftfeuchtigkeit von 25 % (jeweils relative Luftfeuchtigkeit bei 20°C). Die Sperrlage kann jeweils hydrophobierende oder hydrophilierende Mittel aufweisen, beispielsweise entsprechend der
Die Sperrschicht umfasst neben der Lage aus dem rev. WDD-Material vorzugsweise eine zusätzliche Lage aus einem Material, welches das rev. WDD-Material stützt und schützt, z. B. einem textilen Material wie einem Vlies- oder Gewebematerial. Nach dem Ausführungsbeispiel ist die Sperrlage beidseitig von derartigem Material umgeben. Das dieses Material jedoch (praktisch) keinen Einfluss auf die Wasserdampfdiffusion hat, gelten die obigen Angaben zur Wasserdampfdiffusion auch für die Sperrlage.In addition to the location from the rev. WDD material preferably an additional layer of a material that rev. WDD material supports and protects, e.g. B. a textile material such as a nonwoven or woven material. According to the embodiment, the barrier layer is surrounded on both sides by such material. However, since this material has (practically) no influence on water vapor diffusion, the above information on water vapor diffusion also applies to the barrier layer.
