Description

Die Erfindung betrifft einen zur Abdichtung eines Fensterrahmens in Bezug auf eine Laibung geeigneten Schaumstoff-Dichtstreifen, der zumindest teilweise zur verzögerten Rückstellung getränkt ist, wobei der Schaumstoff-Dichtstreifen zwei gegenüberliegende, im Einbauzustand dem Rauminneren bzw. dem Raumäußeren zugewandte Längsseiten aufweist und weiter zur Anlage an der Fensterseite bzw. der Laibung gegenüberliegende Ober- und Unterseite aufweist, wobei weiter der Schaumstoff-Dichtstreifen zugeordnet den Längsseiten durch zusammengefügte unterschiedliche, aber jeweils offenporige Schaumstoffstreifen, die durch eine eine Seite abdeckende Klebelage zusammengehalten sind, unterschiedlich ausgebildet ist, derart, dass sich jedenfalls im Einbauzustand eine unterschiedliche Dampfbremswirkung ergibt.The invention relates to a suitable for sealing a window frame with respect to a soffit foam sealing strip, which is at least partially soaked for delayed recovery, the foam sealing strip has two opposite, in the installed state the room interior or the room outside facing longitudinal sides and further to the plant on the window side or the soffit opposite upper and lower side, said further the foam sealing strips associated with the longitudinal sides by joined different, but each open-pore foam strips, which are held together by a side covering adhesive layer, is formed differently, such that at least in the installed state results in a different vapor barrier effect.

Ein derartiger Schaumstoff-Dichtstreifen ist aus der DE 10 2006 043 050 A1 bekannt. Bei dem bekannten Schaumstoff-Dichtstreifen ist zu diesem Zweck einseitig - bezogen auf eine Längsrandseite - ein nicht lösbar mit dem ansonsten einheitlichen Schaumstoffmaterial des Schaumstoff-Dichtstreifens verbundenes Zusatz-Schaumstoffmaterial vorgesehen. Entweder als geschlossenzelliger Schaumstoff, wodurch sich allein schon bei einer taschenartigen Ausformung des verbleibenden Schaumstoffbereiches, in dem das Zusatz-Schaumstoffmaterial einliegt, die gewünschte höhere Dampfbremswirkung ergibt. Oder in Form von offenzelligem Schaumstoff, wobei durch eine größere Ausgangshöhe des so gebildeten Schaumstoff-Dichtstreifens zugeordnet diesem Längsrandbereich sich im Einbauzustand eine höhere Komprimierung und damit die gewünschte höhere Dampfbremswirkung ergibt.Such a foam-sealing strip is made of DE 10 2006 043 050 A1 known. In the known foam sealing strip is for this purpose on one side - provided on a longitudinal edge side - a non-detachably connected to the otherwise uniform foam material of the foam sealing strip additional foam material. Either as a closed-cell foam, which results in the desired higher vapor barrier effect even with a pocket-like shaping of the remaining foam area in which the additional foam material rests. Or in the form of open-cell foam, which is associated with a higher initial height of the foam sealing strip thus formed associated with this longitudinal edge region in the installed state, a higher compression and thus the desired higher vapor barrier effect.

Zum Stand der Technik ist des Weiteren auf die DE 200 09 674 U1 zu verweisen. Hier sind über die Breite mehrere miteinander verbundene Schaumstoffstreifen vorgesehen, wobei zwischen mindestens zwei der Schaumstoffstreifen eine luftdichte Sperrschicht ausgebildet ist. Eine gleiche Ausgestaltung, jedoch mit gleichen Schaumstoffschichten, ist aus der DE 35 44 277 C1 bekannt.The prior art is further on the DE 200 09 674 U1 to refer. Here, a plurality of interconnected foam strips are provided over the width, wherein between at least two of the foam strips a airtight barrier layer is formed. A same design, but with the same foam layers, is from the DE 35 44 277 C1 known.

Aus der EP 0 317 833 A1 ist ein aus Schaumstoff bestehendes Dichtungselement mit zufolge Tränkung verzögerter elastischer Rückstellfähigkeit bekannt, bei welchem auf jeder Querschnittsfläche ein Teil des Dichtstreifens aus einem zur verzögerten Rückstellung imprägnierten Schaumstoffmaterial besteht, der auf der Querschnittsfläche gegenüberliegende Teil jedoch aus einem aus zufolge Tränkung verzögert elastisch rückstellfähigen geschlossenzelligen Schaumstoff. Dabei kann eine formschlüssige Verbindung eines offenzelligen Schaumstoffs und dem elastisch rückstellfähigen geschlossenzelligen Schaumstoff vorgesehen sein.From the EP 0 317 833 A1 For example, there is known a foamed sealant having a delayed elastic recovery capability in which a portion of the sealant strip is comprised of a delayed recovery impregnated foam material, but the portion facing the cross sectional area is an elastically resilient closed cell foam retarded by impregnation. In this case, a positive connection of an open-cell foam and the elastically resilient closed-cell foam can be provided.

Aus der DE 43 07 528 A1 ist ein Fugendichtungsband aus weichem Schaumstoff, mit zur verzögerten Rückstellung führenden Imprägnierung bekannt, wobei die Imprägnierung über eine Breite des Fugendichtungsbandes unterschiedlich ist, nämlich in einem Rand-Längsbereich, derart dass nach Freigabe der Rückstellung sich ein zu einer Mittellängsachse des Fugendichtungsbandes hin ansteigendes Profil einstellt.From the DE 43 07 528 A1 is a joint sealing strip made of soft foam, known impregnation leading to delayed recovery, wherein the impregnation over a width of the joint sealing strip is different, namely in a longitudinal edge region, so that adjusts the release of the provision adjusts to a central longitudinal axis of the joint sealing strip towards increasing profile ,

Ausgehend von dem zunächst genannten Stand der Technik stellt sich der Erfindung die Aufgabe, einen vorteilhaften Schaumstoff-Dichtstreifen zur Abdichtung eines Fensterrahmens in Bezug auf eine Laibung anzugeben.Based on the first-mentioned prior art, the object of the invention is to provide an advantageous foam-sealing strip for sealing a window frame with respect to a soffit.

Eine mögliche Lösung der Aufgabe ist durch den Gegenstand des Anspruches 1 gegeben, wobei in diesem Fall darauf abgestellt ist, dass die unterschiedlichen Schaumstoffstreifen jeweils zur verzögerten Rückstellung imprägniert sind, dass sich die Schaumstoffstreifen jeweils über die gesamte Dicke des Schaumstoff-Dichtstreifens erstrecken und sich an ihren einander zugewandten Längsseiten zumindest teilweise verklebungsfrei nebeneinander erstrecken, derart, dass der Schaumstoff-Dichtstreifen in Querrichtung luftdurchlässig ist, wobei die Luftdurchlässigkeit des Schaumstoff-Dichtstreifens allein durch die Kombination der Luftdurchlässigkeiten der jeweils imprägnierten Schaumstoffstreifen bestimmt ist, und dass die unterschiedliche Dampfbremswirkung durch eine unterschiedliche Ausgangsdichte und/ oder eine unterschiedliche Imprägnierung der Schaumstoffstreifen erreicht ist. Es liegt ein grundsätzlich luftdurchlässiger Schaumstoff-Dichtstreifen vor, der insgesamt - nur - aus offenporigem Schaumstoff zusammengesetzt ist. Dadurch, dass sich die Schaumstoffstreifen jeweils über die gesamte Dicke des Schaumstoff-Dichtstreifens erstrecken ist ein einfacher Aufbau erreicht. Die verklebungsfreie Erstreckung nebeneinander der Schaumstoff-Dichtstreifen an ihren einander zugewandten Längsseiten, an denen sie auch bevorzugt unmittelbar aneinander anliegen, sorgt für definierte Verhältnisse. Ein gewisser Zusammenhalt ist zwar in der Praxis durch eventuell austretendes Imprägnat an dieser Schnittstelle gegeben. Hierdurch ist aber keine Verklebung im Sinne eines nur zerstörend aufhebbaren Verbundes gegeben. Denn das Imprägnat ist nicht aushärtend. Die unterschiedliche Dampfbremswirkung ist allein durch eine unterschiedliche Ausgangsdichte und/ oder eine unterschiedliche Imprägnierung der Schaumstoffstreifen erreicht. Es bedarf grundsätzlich keiner sonstigen Zusatzmittel wie etwa einer durch Einlegung einer Leiste oder dgl. erreichten höheren Komprimierung oder einer einseitigen Beschichtung.
Da das verklebungsfreie Anliegen der Schaumstoffstreifen an ihren Längsseiten die Luftdurchlässigkeit in Querrichtung des Schaumstoff-Dichtstreifens nicht hindern soll, ist die Möglichkeit gegeben, dass gewisse, die Luftdurchlässigkeit nicht oder nicht wesentlich hindernde Verklebungen vorgesehen sind. Erfindungsgemäß sind die Schaumstoffstreifen an ihren einander zugewandten Längsseiten unter Belassung von verklebungsfreien Bereichen miteinander verklebt. Die verklebungsfreien Bereiche können insbesondere 20% bis 90% der Seitenfläche ausmachen, wobei diese genannte Bandbreite auch alle Zwischenwerte, insbesondere in Ein-Zehntel-Prozent-Schritten in die Offenbarung einschließt.
In weiterer Einzelheit kann eine solche Verklebung rasterartig vorgesehen sein. Weiter kann sie auch durch isolierte Klebepunkte vorgesehen sein. Die Verklebung ist bevorzugt so vorgesehen, dass sie nur zerstörend aufgehoben werden kann, also bspw. unter Mitreißen von miteinander verklebten Schaumstoffbereichen.A possible solution to the problem is given by the subject matter of claim 1, which is in this case based on the fact that the different foam strips are each impregnated for delayed recovery, that the foam strips each extend over the entire thickness of the foam sealing strip and to their sides facing each other at least partially without gluing side by side extend, such that the foam sealing strip is permeable to air in the transverse direction, wherein the air permeability of the foam sealing strip solely by the combination the air permeabilities of the respective impregnated foam strips is determined, and that the different vapor barrier effect is achieved by a different starting density and / or a different impregnation of the foam strips. There is a basically air-permeable foam sealing strip, the total - only - is composed of open-cell foam. The fact that the foam strips each extend over the entire thickness of the foam sealing strip a simple structure is achieved. The non-stick extension side by side of the foam-sealing strips on their mutually facing longitudinal sides, where they also preferably directly abut each other, provides for defined conditions. A certain cohesion is indeed given in practice by any emerging impregnate at this interface. As a result, however, there is no bonding in the sense of a network that can only be broken down in a destructive manner. Because the impregnate is not hardening. The different vapor barrier effect is achieved solely by a different starting density and / or a different impregnation of the foam strips. It requires basically no other additives such as a higher compression achieved by inserting a strip or the like or a one-sided coating.
Since the non-sticking concerns of foam strips on their long sides should not prevent the air permeability in the transverse direction of the foam sealing strip, there is the possibility that certain, the air permeability or not significantly hindering bonds are provided. According to the invention, the foam strips are bonded to one another on their longitudinal sides facing one another, leaving no gluing-free areas. In particular, the non-adherent regions can make up 20% to 90% of the side surface, whereby said bandwidth also includes all intermediate values, in particular in one-tenths of a percent increments, in the disclosure.
In further detail, such an adhesive bond may be provided in a grid-like manner. Furthermore, it can also be provided by insulated adhesive dots. The bonding is preferably provided so that it can be lifted only destructive, so for example. Under entrainment of foam areas bonded together.

Bezüglich des Imprägnierungsmittels handelt es sich in weiterer Einzelheit bevorzugt um ein acrylatbasiertes Imprägnierungsmittel. Es ist darüber hinaus bevorzugt derart eingestellt, dass sich ein beispielsweise auf eine Glasplatte aufgepresster imprägnierter Schaumstoffstreifen rückstandslos entfernen lässt. Dies ist bei einem Klebstoff, wie er beispielsweise auch für den Selbstklebestreifen zum Einsatz kommt, nicht möglich.
Die Rohdichten der verwendeten Schaumstoffe können zwischen 20 und 50, bevorzugt zwischen 25 und 40 kg/m3 gewählt sein. Im imprägnierten Zustand, welches dann auch der hier angesprochenen Ausgangsdichte entspricht, kann eine Dichte zwischen 40 und 120, bevorzugt zwischen 50 und 100 kg/m3 gewählt sein. In die Offenbarung sind auch die Zwischenwerte jeweils im Einzelnen mit eingeschlossen. Also beispielsweise 21 oder 49 oder 41, 119 etc. kg/m3. Die unterschiedliche Dampfbremswirkung kann durch die Dampfdiffusionswiderstandszahl µ ausgedrückt werden. Dies ist ein Maß dafür, welchen Widerstand der - getränkte - Schaumstoffstreifen dem Wasserdampf (Luftfeuchte) im Vergleich zu einem Meter Luftschichtdicke entgegensetzt. Auf die DIN 18542 ist zu verweisen. Der dem Rauminneren zugewandte Schaumstoffstreifen kann hierbei beispielsweise einen µ-Wert von 5 bis 20, bevorzugt 8 bis 15, weiter bevorzugt 10 aufweisen. Dagegen kann der dem Raumäußeren zugewandte Schaumstoffstreifen einen µ-wert von 2 bis 15, bevorzugt 4 bis 10, weiter bevorzugt 4,5 oder 5 aufweisen. Auch in diese Werte sindjeweils alle Zwischenwerte, auch im Zehntelschrittbereich, in die Offenbarung einbezogen. Weitere Merkmale der Erfindung sind nachstehend, auch in der Figurenbeschreibung, oftmals in ihrer bevorzugten Zuordnung zum Gegenstand des Anspruches 1 oder zu Merkmalen weiterer Ansprüche erläutert. Sie können aber auch in einer Zuordnung zu nur einzelnen Merkmalen des Anspruches 1 oder des jeweiligen weiteren Anspruches oder auch jeweils unabhängig von Bedeutung sein.With regard to the impregnating agent, in further detail it is preferably an acrylate-based impregnating agent. In addition, it is preferably set in such a way that a impregnated foam strip pressed onto a glass plate, for example, can be removed without residue. This is not possible with an adhesive, as used, for example, for the self-adhesive strip.
The bulk densities of the foams used may be between 20 and 50, preferably between 25 and 40 kg / m 3 . In the impregnated state, which then also corresponds to the starting density mentioned here, a density between 40 and 120, preferably between 50 and 100 kg / m 3 can be selected. The interim values are also included in detail in the disclosure. So for example 21 or 49 or 41, 119 etc. kg / m 3 . The different vapor barrier effect can be expressed by the vapor diffusion resistance coefficient μ. This is a measure of what resistance the - impregnated - foam strip opposes the water vapor (humidity) compared to one meter air layer thickness. Reference is to be made to DIN 18542. The foam strip facing the interior of the room may in this case have, for example, a μ value of 5 to 20, preferably 8 to 15, more preferably 10. By contrast, the foam strip facing the exterior can have a μ value of 2 to 15, preferably 4 to 10, more preferably 4.5 or 5. Also in these values, all intermediate values, even in the tenth step range, are included in the disclosure. Further features of the invention are explained below, also in the description of the figures, often in their preferred association with the subject matter of claim 1 or with features of further claims. But you can even in an assignment to only individual features of claim 1 or the respective further claim or each independently of importance.

So ist es bevorzugt, dass die Schaumstoffstreifen eine gleiche Ausgangsdicke aufweisen. Im vollständig zurückgestellten Zustand, der allerdings in der Praxis so nicht erreicht wird, da im Einbauzustand immer eine gewisse Komprimierung verbleibt, stellen sich die nebeneinander liegenden Schaumstoffstreifen also auf eine gleiche Höhe zurück. Dies bedeutet aber auch, dass die Rückstellkräfte über die Breite des Schaumstoff-Dichtstreifens praktisch gleich sind.Thus, it is preferred that the foam strips have a same initial thickness. In the fully reset state, which is not achieved in practice, however, since a certain amount of compression always remains in the installed state, the juxtaposed foam strips thus return to an equal height. But this also means that the restoring forces over the width of the foam sealing strip are practically the same.

Darüber hinaus ist bevorzugt, dass die Breite der Schaumstoffstreifen unterschiedlich ist. Hierdurch kann eine vorteilhafte Anpassung an die Einsatzbedingungen erreicht werden. Etwa indem der dem Raumäußeren zugeordnete Schaumstoffstreifen, der mehr den Witterungseinflüssen ausgesetzt ist, über eine größere Tiefe ausgebildet ist als der dem Rauminneren zugewandte Schaumstoffstreifen. Letzteres ist nämlich auch die weiter bevorzugte Gestaltung, wenn auch in Einzelfällen eine umgekehrte Ausgestaltung möglich ist, dass nämlich der der inneren Seite zugewandte Schaumstoffstreifen die geringere Breite aufweist.Moreover, it is preferred that the width of the foam strips is different. As a result, an advantageous adaptation to the operating conditions can be achieved. For example, in that the foam strip assigned to the outside of the room, which is more exposed to the effects of the weather, is formed over a greater depth than the foam strip facing the interior of the room. The latter is in fact also the further preferred embodiment, although in some cases a reverse configuration is possible, namely that the foam strip facing the inner side has the smaller width.

Dargestellt und beschrieben ist mit Bezug zu den Fig. 1 bis 3 ein Schaumstoff-Dichtstreifen 1, der bevorzugt zum Einbau zwischen einem Fensterrahmen 2 und einer durch eine Mauer 3 gegebene Laibung 4 eines Gebäudes dient, siehe Fig. 3.Shown and described is with reference to the Fig. 1 to 3 a foam sealing strip 1, which is preferably used for installation between a window frame 2 and a given by a wall 3 soffit 4 of a building, see Fig. 3 ,

Der Schaumstoff-Dichtstreifen 1 setzt sich zusammen aus zwei parallel zueinander verlaufenden Schaumstoffstreifen 5, 6. Bevorzugt setzt er sich auch nur aus diesen zwei Schaumstoffstreifen 5, 6 zusammen. Die Schaumstoffstreifen 5, 6 liegen an ihren einander zugewandten Innen-Längsseiten 7, 8 unmittelbar aneinander an. Sie können auch einen Spalt zwischen sich belassen. Beide Schaumstoffstreifen 5, 6 bestehen aus einem offenporigen bzw. offenzelligen Weichschaumstoff. Die zusammengefassten Schaumstoffstreifen 5, 6 bzw. der Schaumstoff-Dichtstreifen 1 weist weiter eine zur Anlage an der Fensterseite kommende Oberseite 9 und eine zur Anlage an der Laibung kommende Unterseite 10 (siehe Fig. 3) auf.
Die Schaumstoffstreifen 5, 6 sind durch eine zugleich die Oberseite 9 bildende Klebelage 11 zusammengehalten. Die Klebelage 11 besteht beim Ausführungsbeispiel aus einer doppelseitigen Selbstklebeschicht, wobei der Klebstoff beispielsweise in ein Vliesmaterial oder Gewebematerial getränkt vorgesehen sein kann.The foam sealing strip 1 is composed of two mutually parallel foam strips 5, 6. Preferably, it is also composed only of these two foam strips 5, 6 together. The foam strips 5, 6 are located at their mutually facing inner longitudinal sides 7, 8 directly to each other. You can also leave a gap between them. Both foam strips 5, 6 consist of an open-pore or open-cell flexible foam. The combined foam strips 5, 6 or the foam-sealing strip 1 further has an upper side 9 which comes to bear against the window side and an underside 10 coming into contact with the reveal (see FIG Fig. 3 ) on.
The foam strips 5, 6 are held together by a simultaneously forming the top 9 adhesive layer 11. The adhesive layer 11 consists in the embodiment of a double-sided self-adhesive layer, wherein the adhesive may be provided soaked, for example, in a nonwoven material or fabric material.

Beide Schaumstoffstreifen 5, 6 sind zur verzögerten Rückstellung imprägniert. Beide Schaumstoffstreifen 5, 6 erstrecken sich auch über die gesamte Dicke d des Schaumstoff-Dichtstreifens 1. Bevorzugt sind auch, wie im Ausführungsbeispiel dargestellt, die einander zugewandten Längsrandseiten 7, 8 der Schaumstoffstreifen 5, 6 senkrecht verlaufend zu der Oberseite 9 bzw. der Unterseite 10. Somit ist in jeder Längsebene, die auf der Oberseite 9 bzw. der Unterseite 10 senkrecht steht, nur ein und dasselbe Schaumstoffmaterial, entweder des Schaumstoffstreifens 5 oder des Schaumstoffstreifens 6, gegeben.Both foam strips 5, 6 are impregnated for delayed recovery. Both foam strips 5, 6 extend over the entire thickness d of the foam sealing strip 1. Preferably, as shown in the embodiment, the longitudinal edges facing each other 7, 8 of the foam strips 5, 6 perpendicular to the top 9 and the bottom 10. Thus, in each longitudinal plane which is perpendicular to the top 9 and the bottom 10, only one and the same foam material, either the foam strip 5 or the foam strip 6, given.

Bei dem gewählten Schaumstoffmaterial handelt es sich weiter bevorzugt um einen Polyurethan-Weichschaum. Dieser ist jeweils zur verzögerten Rückstellung imprägniert. Beispielsweise durch ein acrylatbasiertes Imprägnat. In der Bevorratungsstellung kann der Schaumstoff-Dichtstreifen 1 auch in einer aufreißbaren Umhüllungsfolie gehalten sein. Hierzu sei etwa auf die EP 1 131 525 B1 verwiesen.The selected foam material is more preferably a flexible polyurethane foam. This is each impregnated for delayed recovery. For example, by an acrylate-based impregnate. In the storage position, the foam sealing strip 1 may also be held in a tearable wrapping film. This is about on the EP 1 131 525 B1 directed.

Die Breiten B1 des Schaumstoffstreifens 5 bzw. B2 des Schaumstoffstreifes 6 sind unterschiedlich. B2 ist beim Ausführungsbeispiel kleiner als B1. B2 entspricht bevorzugt etwa 10 bis 49 % von B1, wobei auch sämtliche Zwischenwerte, nicht nur in Form von ganzen Zahlen, sondern auch in hundertstel oder zehntel Werten in die Offenbarung mit eingeschlossen sind, derart, dass jeder solcher Zwischenwert als exakter Wert oder Bereich-Grenzwert beansprucht werden kann.The widths B1 of the foam strip 5 or B2 of the foam strip 6 are different. B2 is smaller than B1 in the embodiment. B2 preferably corresponds to about 10 to 49% of B1, whereby all intermediate values, not only in the form of integers but also in hundredths or tenths of values are included in the disclosure such that each such intermediate value can be claimed as an exact value or range limit.

Dagegen ist die Ausgangs-Dicke der Schaumstoffstreifen bevorzugt gleich. Also die Dicke vor einer Komprimierung oder nach erfolgter vollständiger Rückstellung.By contrast, the starting thickness of the foam strips is preferably the same. So the thickness before compression or after full recovery.

Weiterhin ist aber wesentlich, dass die Schaumstoffstreifen 5, 6 eine unterschiedliche Dampfbremswirkung besitzen. Diese kann einerseits durch eine unterschiedlich starke Imprägnierung oder die Wahl einer unterschiedlichen Dichte des Schaumstoff-Ausgangsmaterials erreicht sein. Hierbei ist die Dampfbremswirkung der Gebäudeinnenseite zugewandt höher eingestellt als der Gebäudeaußenseite zugewandt.Furthermore, it is essential that the foam strips 5, 6 have a different vapor barrier effect. This can be achieved on the one hand by a different degrees of impregnation or the choice of a different density of the foam starting material. Here, the vapor barrier effect facing the inside of the building facing set higher than the building exterior.

Die Breite, also die Summe aus B1 und B2, des Schaumstoff-Dichtstreifens entspricht im komprimierten Bevorratungszustand etwa einem Zehnfachen der Dicke d, während im Einbauzustand, das heißt im dekomprimierten Ruhezustand, ein Verhältnis von der genannten Breite zu der Dicke von etwa 5:1 vorliegt (Diese Dicke wird fachmännisch auch als Fugenbreite bezeichnet während das vorstehend als Breite angesprochene - zusammengesetzte - Maß auch fachmännisch als Fugentiefe bezeichnet wird). Die Gesamtbreite, B1 plus B2, eines solchen Schaumstoff-Dichtstreifens 1 entspricht der Gesamtbreite eines Fensterrahmens, liegt also beispielsweise zwischen 5 und 20 cm. Im Falle eines Spaltes zwischen den Schaumstoffstreifen ist dieser Spalt in die genannte Gesamtbreite auch mit einbezogen.The width, ie the sum of B1 and B2, of the foam sealing strip corresponds to approximately ten times the thickness d in the compressed storage state, while in the installed state, that is to say in the decompressed state of rest, a ratio of said width to the thickness of approximately 5: 1 (This thickness is expertly referred to as the joint width while the above referred to as width - composite - measure is also referred to expertly as joint depth). The overall width, B1 plus B2, of such a foam sealing strip 1 corresponds to the total width of a window frame, that is, for example, between 5 and 20 cm. In the case of a gap between the foam strips this gap is also included in the said total width.

Die Klebelage 11 ist im Verwahrzustand von einer Schutzfolie 9 überdeckt. Es kann sich etwa um eine silikonisierte Folie handeln.The adhesive layer 11 is covered in the storage state of a protective film 9. It may be about a siliconized film.

Bei der Ausführungsform der Fig. 4, die im Übrigen der Ausführungsform der Fig. 2 entspricht, ist zwischen den einander zugewandten Innen- und Längsseiten 7,8 der Schaumstoffstreifen 5,6 eine Verklebung 12 vorgesehen. Die Verklebung 12 ist so ausgeführt, dass sich zwischen einzelnen Verklebungen 12 ein Bereich a ergibt, in dem die Schaumstoffstreifen 5,6, wie zuvor auch beschrieben, lediglich aneinander anliegen (oder gar entsprechend der Darstellung durch einen Spalt voneinander gesondert sind).In the embodiment of the Fig. 4 Incidentally, the embodiment of the Fig. 2 corresponds, is provided between the mutually facing inner and longitudinal sides 7,8 of the foam strip 5,6 12 gluing. The bond 12 is designed so that there is a region a between individual bonds 12, in which the foam strips 5, 6, as also described above, rest against one another only (or are separated from each other by a gap, as shown).

In Fig. 5 zeigt die Darstellung eine mögliche Ausgestaltung der Verklebung 12 in Form von verkürzend angeordneten Klebestreifen. Die Klebestreifen können sich unter Einschluss eines spitzen Winkels zu der Oberseite 9 bzw. der Klebelage 11 erstrecken. Im Einzelnen ergeben sich bei der dargestellten Ausführungsform rautenförmige Zwischenbereiche a. Die Zwischenbereiche a sind solche Bereiche, in denen die Schaumstoffstreifen 5, 6 verklebungsfrei aneinander anliegen bzw. gar voneinander distanziert sind.In Fig. 5 shows the representation of a possible embodiment of the bond 12 in the form of shortened adhesive strips. The adhesive strips may extend to include an acute angle to the top 9 and the adhesive layer 11. In detail, diamond-shaped intermediate regions a result in the illustrated embodiment. The intermediate areas a are those areas in which the foam strips 5, 6 rest against each other without any adhesion or even are distanced from one another.
