Description

Die Erfindung betrifft eine wasserdichte Dichtungsbahn, welche sich insbesondere zur Verwendung im Hoch- und Tiefbau eignet.The invention relates to a waterproof membrane, which is particularly suitable for use in building and civil engineering.

Es ist bereits bekannt, Folien aus Kunststoff in der Weise als Dichtungsmaterial zu verwenden, daß man-die bahnförmigen Folien überlappend auf einen Untergrund aufbringt und zur Verbindung der Bahnen im Überlappungsbereich ein Band aus selbstklebender profilierter Dichtungsmasse, z.B. aus Butylkautschuk, zwischen die Folien legt. Das hierfür benötigte Klebeband ist zum Zweck des Transports und der Handhabung bei der Verlegung zwischen zwei Schichten einer abziehbaren Schutzfolie, beispielsweise aus Silikonpapier, eingelegt. Aus der DE-OS 25 10 162 ist es bekannt, Dichtungsbahnen aus Gummi bereits bei ihrer Herstellung mit einem Klebeband zu versehen; dabei ist ein Klebeband an einem Längsrand an der Oberseite und ein weiteres Klebeband an dem gegenüberliegenden Rand an der Unterseite angebracht. Die Klebebänder können mit Silikonpapier abgedeckt sein.It is already known to use plastic films as a sealing material in such a way that the web-shaped films are applied overlapping to a substrate and a tape made of self-adhesive profiled sealing compound, for example made of butyl rubber, is placed between the films to connect the webs in the overlap area. The adhesive tape required for this purpose is placed between two layers of a removable protective film, for example made of silicone paper, for the purpose of transport and handling when laying. From DE-OS 25 1 0 162 it is known to provide sealing sheets made of rubber with an adhesive tape during their manufacture; an adhesive tape is attached to a longitudinal edge on the top and a further adhesive tape on the opposite edge on the underside. The adhesive tapes can be covered with silicone paper.

Dichtungsbahnen aus Kunststoff können auch mit Hilfe von Lösungsmitteln oder durch Erhitzen verschweißt werden.Plastic sealing sheets can also be welded using solvents or by heating.

Die Verlegung derartiger Dichtungsbahnen ist sehr umständlich und schon bei geringsten Ungenauigkeiten beim Einlegen des Klebebandes oder beim Verschweißen wird im Uberlappungsbereich keine dichte Verbindung erhalten.The laying of such sealing sheets is very cumbersome and even with the slightest inaccuracies when inserting the adhesive tape or when welding, no tight connection is obtained in the overlap area.

Eine aus dem DE-GM 79 o7 342 bekannte Dichtungsbahn besteht aus einer Bitumenschicht, die auf der Unterseite mit einem Vliesmaterial und auf der Oberseite mit Sand abgedeckt ist, wobei zur Verbindung im Randbereich eine blanke, nicht abgedeckte Zone vorgesehen ist. Zum Verschweißen der Bahnen muß erhitzt werden.A sealing membrane known from DE-GM 79 o7 342 consists of a bitumen layer which is covered on the underside with a non-woven material and on the top with sand, a bare, uncovered zone being provided for connection in the edge region. Heating is required to weld the sheets.

Aus der DE-OS 16 21 939 sind ferner Dichtungsmaterialien bekannt, welche aus einer flexiblen Folie mit einer Beschichtung aus einer selbstklebenden Dichtungsmasse bestehen. Das bevorzugte Material für die Dichtungsmasse ist eine Bitumen/Kautschukmasse. Auch dieses Material wird bahnweise überlappend in der Weise verlegt, daß die selbstklebende Dichtungsmasse an dem abzudichtenden Untergrund haftet und durch die Deckfolie geschützt ist. Im Überlappungsbereich liegt die selbstklebende Dichtungsmasse der oberen Bahn.auf der Deckfolie der unteren Bahn, so daß eine Verklebung Masse auf Folie erreicht wird. Bei nicht vollständig glatter Verlegung der Bahnen, z.B. wegen Unebenheiten des Untergrundes, oder bei Spannungen aufgrund von Temperaturschwankungen kann es jedoch im Uberlappungsbereich zu einer unvollständigen Verklebung zwischen Dichtungsmasse und Folie bzw. zu einer Bildung von Kapillaren kommen, durch welche Wasser eindringen kann.From DE-OS 16 21 939 sealing materials are also known which consist of a flexible film with a coating of a self-adhesive sealant. The preferred material for the sealant is a bitumen / rubber compound. This material is also laid overlapping in layers in such a way that the self-adhesive sealant adheres to the surface to be sealed and is protected by the cover film. In the area of overlap, the self-adhesive sealing compound of the upper sheet lies on the cover sheet of the lower sheet, so that bonding compound to sheet is achieved. If the membrane is not completely smooth, e.g. due to unevenness in the substrate, or if there is tension due to temperature fluctuations, incomplete bonding between the sealant and the film or the formation of capillaries through which water can penetrate can occur.

Aus der US-PS 41 72 83o ist es bekannt, ein Dichtungsmaterial der vorstehend angegebenen Art so abzuwandeln, daß auf die Bitumen/Kautschukmasse eine an der Außenseite silikonisierte Polyethylenfolie als Deckschicht aufgebracht wird, welche einen etwa 1o cm breiten Randbereich nicht abdeckt; letzterer ist mit einer abziehbaren Schutzfolie bedeckt. Auf diese Weise wird bei überlappender Verlegung der Bahnen eine bessere Verbindung erreicht, doch kann auf die silikonisierte Oberfläche kein weiteres Material aufgeklebt werden. Es kommt hinzu, daß sich derartige bitumenbeschichtete Dichtungsbahnen nicht überall einsetzen lassen; sie sind beispielsweise nicht für eine Verlegung auf bestimmten Wärmedämm-Materialien geeignet, welche in zunehmendem Maße sowohl im Innenausbau als auch für Dachabdeckungen eingesetzt werden.From US-PS 41 72 83o it is known to modify a sealing material of the type specified above in such a way that a polyethylene film siliconized on the outside is applied as a cover layer to the bitumen / rubber composition, which does not cover an approximately 10 cm wide edge area; the latter is covered with a removable protective film. In this way, a better connection is achieved when the sheets are laid overlapping, but no further material can be glued to the siliconized surface. In addition, bitumen-coated waterproofing membranes of this type cannot be used everywhere; for example, they are not suitable for laying on certain thermal insulation materials, which are increasingly being used both in interior construction and for roof coverings.

Der Erfindung liegt demgegenüber die Aufgabe zugrunde, eine Dichtungsbahn zu entwickeln, welche nicht nur die Vorteile der herkömmlichen Materialien aufweist, sondern sich darüber hinaus besonders bequem und problemlos verlegen läßt und dabei eine völlig wasserdichte Schicht liefert. Insbesondere soll mit Hilfe der Erfindung eine zuverlässig dichte, homogene-Verbindung im überlappungsbereich der Dichtungsbahnen erzielt werden, eine Verlegung auf Substraten aller Art möglich sein und ein Aufbringen weiterer Materialien durch Verkleben nicht ausgeschlossen sein.In contrast, the invention is based on the object of developing a sealing membrane which not only has the advantages of the conventional materials, but moreover can be laid particularly conveniently and easily, and at the same time one provides completely waterproof layer. In particular, with the aid of the invention, a reliably tight, homogeneous connection is to be achieved in the overlap area of the sealing sheets, laying on substrates of all kinds should be possible, and application of further materials by adhesive bonding should not be ruled out.

Gegenstand der Erfindung ist eine Dichtungsbahn zur Verwendung im Hoch- und Tiefbau auf Basis einer plastisch-elastischen selbstklebenden Dichtungsmasse und einer flexiblen Schicht, welche dadurch gekennzeichnet ist, daß die Dichtungsmasse zwischen zwei flexiblen Schichten eingeschlossen ist, wobei die untere Schicht die Dichtungsmasse im Bereich einer Längsseite und die obere Schicht die Dichtungsmasse im Bereich der gegenüberliegenden Längsseite nicht abdeckt und so einen überstand für die überlappende Verbindung der Bahnen bilden. Gemäß einer bevorzugten Ausführungsform lassen die obere Schicht im Bereich der einen Längsseite und die untere Schicht im Bereich der anderen Längsseite einen schmalen Streifen der Dichtungsmasse als Fixierungsrand frei, welcher jeweils auf der dem Überlappungsüberstand gegenüberliegenden Seite angeordnet ist.The invention relates to a sealing membrane for use in building and civil engineering based on a plastic-elastic self-adhesive sealant and a flexible layer, which is characterized in that the sealant is enclosed between two flexible layers, the lower layer of the sealant in the region of a Long side and the upper layer does not cover the sealing compound in the area of the opposite long side and thus form a protrusion for the overlapping connection of the webs. According to a preferred embodiment, the upper layer in the area of one long side and the lower layer in the area of the other long side leave a narrow strip of the sealing compound as a fixing edge, which is arranged on the side opposite the overlap projection.

Als Dichtungsmasse sind Bitumen/Kautschukmischungen besonders geeignet, wobei ihre hervorragenden Temperatureigenschaften wichtig sind: Sie lassen sich noch bis -30°C um 18o0 biegen und zeigen andererseits bis zu Temperaturen von +80°C noch kein Fließen, d.h. eine ausreichende Standfestigkeit. Eine Verlegung der Dichtungsbahnen ist bereits bei Temperaturen um 0°C möglich, da die selbstklebenden Eigenschaften der Dichtungsmasse dann für eine homogene Verbindung schon ausreichen. Eine geeignete Dichtungsmasse für die erfindungsgemäße Dichtungsbahn besteht z.B. aus 4o bis 8o Gewichtsteilen'Bitumen (Erweichungspunkt 6o bis 100°C nach DIN 1995), 15 bis 45 Teilen aromatisches öl und 5 bis 15 Teilen Kautschuk, z.B. einem Styrol/Butadien-Copolymer. Die Schichtdicke für die selbstklebende Dichtungsmasse liegt zwischen etwa o,4 und 3 mm, vorzugsweise zwischen 1 und 2 mm, insbesondere bei etwa 1,5 mm.Bitumen / rubber mixtures are particularly suitable as sealing compounds, whereby their excellent temperature properties are important: They can be bent by 18o 0 to -30 ° C and show on the other hand no flow up to temperatures of + 80 ° C, ie sufficient stability. It is possible to lay the sealing membrane at temperatures around 0 ° C, since the self-adhesive properties of the sealing compound are then sufficient for a homogeneous connection. A suitable sealing compound for the sealing membrane according to the invention consists, for example, of 40 to 80 parts by weight of bitumen (softening point 60 to 100 ° C. according to DIN 1995), 15 to 45 parts of aromatic oil and 5 to 15 parts of rubber, for example a styrene / butadiene copolymer. The layer thickness for the self-adhesive sealant is between approximately 0.4 and 3 mm, preferably between 1 and 2 mm, in particular approximately 1.5 mm.

Als Folien eignen sich solche aus Polyvinylchlorid oder -fluorid, EPDM-Kautschnk, Butylkautschuk, Chloropren oder Naturkautschuk, d.h. Materialien mit einer ausreichenden Elastizität, die selbst bei größerer mechanischer oder thermischer Beanspruchung nicht reißen, insbesondere aber Polyolefinfolien, d.h. Folien aus Polyethylen oder Polyethylen/Polypropylen, die mono- oder biaxial gestreckt sein können. Die Stärke der Folien liegt zwischen 4o und 5oo, vorzugsweise zwischen 60 und 200, insbesondere bei eta 100 µm. Bei Verwendung von laminierten Folien können beispielsweise zwei Folien von je 5o µm Stärke miteinander verbunden sein.Suitable films are those made of polyvinyl chloride or fluoride, EPDM rubber, butyl rubber, chloroprene or natural rubber, i.e. Materials with sufficient elasticity that will not tear even with greater mechanical or thermal stress, but in particular polyolefin films, i.e. Films made of polyethylene or polyethylene / polypropylene, which can be stretched mono- or biaxially. The thickness of the foils is between 4o and 5oo, preferably between 60 and 200, in particular around 100 µm. When using laminated foils, for example, two foils each with a thickness of 50 μm can be connected to one another.

Für bestimmte Zwecke sind auch Metallfolien geeignet, obwohl sie eine geringere Elastizität besitzen. Besonders günstig sind mit Metallen, z.B. mit Aluminium oder Kupfer bedampfte Kunststoffolien oder laminierte Metall/Kunststoffolien, z.B. aus einer Aluminiumfolie zwischen zwei Polyethylenfolien. Derartige Folien zeichnen sich insbesondere durch ihre Wasserdampfdichtigkeit aus, was sie z.B. zur Verwendung im Kühlhausbau besonders geeignet macht.Metal foils are also suitable for certain purposes, although they have a lower elasticity. Particularly favorable are metals, for example plastic foils vapor-coated with aluminum or copper, or laminated metal / plastic foils, for example made of an aluminum foil between two polyethylene foils. Such films are particularly characterized by their water vapor tightness, which makes them particularly suitable, for example, for use in cold store construction.

Die erfindungsgemäße Dichtungsbahn kann auch so aufgebaut sein, daß die obere flexible Schicht aus einer Folie und die untere aus einem Faservlies oder einer mit einem Faservlies kaschierten Kunststoffolie besteht. Man erhält auf diese Weise eine Dichtungsbahn, welche sich wesentlich besser als eine Kunststoffolie mit Hilfe von Klebstoff mit einem Untergrund verkleben läßt, was insbesondere dann wünschenswert sein kann, wenn die Dichtungsbahnen nach dem Verlegen nicht beschwert werden können, beispielsweise mit Hilfe einer Kiesschüttung. Eine weitere Möglichkeit besteht darin, daß die untere flexible Schicht der erfindungsgemäßen Dichtungsbahn aus einem Gittergewebe besteht, so daß durch Andrücken an den Untergrund ein Durchkleben (stellenweise Selbstverklebung mit dem Untergrund) erreicht werden kann. Im Naht- bzw. überlappungsbereich zwischen den Bahnen wird in allen diesen Fällen die -homogene und dichte Verbindung jeweils dadurch erreicht, daß ein selbstklebender Seitenbereich über einem anderen liegt.The sealing membrane according to the invention can also be constructed in such a way that the upper flexible layer consists of a film and the lower one consists of a non-woven fabric or a plastic film laminated with a non-woven fabric. In this way, a sealing membrane is obtained which can be bonded to a substrate much better than a plastic film with the aid of adhesive, which can be particularly desirable if the sealing membranes cannot be weighed down after installation, for example with the aid of a gravel fill. A further possibility is that the lower flexible layer of the sealing membrane according to the invention consists of a mesh fabric, so that by pressing against the substrate it is possible to stick through (self-adhesive in places with the substrate). In all of these cases, in the seam or overlap area between the webs, the -homogeneous and tight connection is achieved in that one self-adhesive side area lies over another.

Die Dichtungsbahnen gemäß Erfindung können in unterschiedlichen Breiten hergestellt und eingesetzt werden. Eine günstige Breite liegt bei etwa o,9 bis 1,2 m. Die Breite des selbstklebenden Bereiches an der oberen Fläche längs der einen Seite und an der unteren Fläche längs der gegenüberliegenden Seite soll bis zu 1o cm, z.B. etwa 2 bis 8, günstigerweise 4 bis 7, insbesondere aber etwa 7 bis 8 cm betragen. Gegenüber den Materialien der DE-OS 16 21 939 ist es ein zusätzlicher Vorteil der erfindungsgemäßen Dichtungsbahn, daß der Überlappungsbereich eine geringere Breite aufweisen kann, weil durch das Aufeinandertreffen von zwei Bereichen mit selbstklebender Dichtungsmasse eine besonders homogene und dichte Verbindung erreicht wird.The sealing sheets according to the invention can be manufactured and used in different widths. A favorable width is about 0.9 to 1.2 m. The width of the self-adhesive area on the upper surface along one side and on the lower surface along the opposite side should be up to 10 cm, e.g. about 2 to 8, advantageously 4 to 7, but in particular about 7 to 8 cm. Compared to the materials of DE-OS 16 21 939, it is an additional advantage of the sealing membrane according to the invention that the overlap area can have a smaller width because a particularly homogeneous and tight connection is achieved by the meeting of two areas with self-adhesive sealant.

Der gegebenenfalls vorgesehene Fixierungsrand ist normalerweise wesentlich schmäler als der gegenüberliegende überstand für die überlappende Verbindung der Bahnen. Der Fixierungsrand hat demgemäß vorzugsweise eine Breite von etwa o,5 bis 2, insbesondere etwa 1 cm. Der Fixierungsrand ist ebenfalls mit einer Schutzfolie, beispielsweise einem Silikonpapier abgedeckt. Er dient einmal zur a Fixierung der Bahnen auf dem Untergrund ohne zusätzliche Hilfsmittel, was die Verlegung beträchtlich erleichtert. Der an'der Oberseite liegende Fixierungsrand ermöglichst zum anderen ein Festlegen nachfolgender Schichten, z.B. von Schutzvliesen oder dergleichen.The optionally provided fixing edge is normally much narrower than the opposite overhang for the overlapping connection of the webs. The fixing edge accordingly preferably has a width of approximately 0.5 to 2, in particular approximately 1 cm. The fixing edge is also covered with a protective film, for example a silicone paper. It is used to fix the sheets on the substrate without additional aids, which considerably simplifies the laying. The an'der top lying F ixierungsrand ermöglichst the other hand a set of subsequent layers, for example of fleeces or the like.

Für die Lagerung und den Transport werden die selbstklebenden Bereiche der erfindungsgemäßen Dichtungsbahn günstigerweise mit einer abziehbaren Schutzfolie abgedeckt, welche beim Verlegen des Materials entfernt wird. Bevorzugt findet hierfür silikonisiertes Papier Verwendung.For storage and transport, the self-adhesive areas of the invention The sealing membrane is advantageously covered with a removable protective film, which is removed when the material is laid. Siliconized paper is preferably used for this.

Die erfindungsgemäße Dichtungsbahn aus selbstklebender plastisch-elastischer Dichtungsmasse zwischen zwei flexiblen Schichten zeichnet sich insbesondere dadurch aus, daß die obere Schicht gewissermaßen auf der unteren schwimmt, was einen Ausgleich von mechanischen oder thermischen Spannungen beträchtlich begünstigt. Darüber hinaus vereinigt dieses Mateiral in sich praktisch die vorteilhaften Eigenschaften einer einfachen Kunststofffolie und einer mit einer Dichtungsmasse beschichteten Kunststoffolie: Es kann auch dort verlegt werden, wo die direkte Aufbringung von Bitumen- oder Klebemassen, sei es durch Gießen, Streichen oder in Form von Bitumen-Trägerfolien, nicht möglich ist; gegenüber einfachen Folien weist das Material selbstheilende Eigenschaften auf, weil die Dichtungsmasse selbst Löcher in beiden Deckfolien verschließt, wie sie beispielsweise beim Durchtreten von einzelnen Kiessteinen beim Verlegen des Materials entstehen können.The sealing sheet according to the invention, made of self-adhesive, plastic-elastic sealing compound between two flexible layers, is characterized in particular by the fact that the upper layer floats to a certain extent on the lower one, which considerably promotes a compensation of mechanical or thermal stresses. In addition, this material combines practically the advantageous properties of a simple plastic film and a plastic film coated with a sealing compound: It can also be installed where the direct application of bitumen or adhesive compounds, whether by pouring, brushing or in the form of bitumen - carrier films, is not possible; Compared to simple foils, the material has self-healing properties because the sealing compound itself closes holes in both cover foils, such as can occur when individual gravel stones pass through when laying the material.

Die Verwendung von dünnen Einzelfolien gibt der Gesamtbahn eine große Flexibilität, die besser ist als diejenige von dicken Abdichtungsbahnen aus einer Einzelfolie mit vergleichbarer Festigkeit.The use of thin individual foils gives the entire web great flexibility, which is better than that of thick sealing webs made of a single foil with comparable strength.

Die Herstellung der erfindungsgemäßen Dichtungsbahn mit einer zwischen zwei flexiblen Schichten eingeschlossenen selbstklebenden Dichtungsmasse kann in besonders günstiger Weise so erfolgen, daß einem Walzenstuhl mit zwei gekühlten Walzen die beiden Schichtmaterialien, z.B. zwei Folien von oben trichterförmig zugeführt werden, wobei in jeweils einem Randbereich ein Silikonpapierstreifen überlappend in etwas größerer Breite mitgeführt wird. Die Dichtungsmasse wird in den von den beiden zugeführten Folien und dem Silikonpapier gebildeten Trichter gegeben und die Schichtdicke der Dichtungsmasse und zugleich auch die der fertigen Dichtungsbahn werden durch den Abstand der beiden Walzen voneinander gesteuert. Der zum Verkleben der Dichtungsbahn beim späteren überlappenden Verlegen dienende Bereich an den beiden Längsseiten wird dadurch erhalten, daß hier an je einer Seite die Folie nicht bis zum Rand reicht, sondern durch das abziehbare Silikonpapier ersetzt ist.The sealing membrane according to the invention with a self-adhesive sealing compound enclosed between two flexible layers can be produced in a particularly favorable manner in such a way that the two layer materials, e.g. Two foils are fed from above in a funnel shape, with a silicone paper strip being carried overlapping in a somewhat larger width in each edge region. The sealing compound is placed in the funnel formed by the two supplied films and the silicone paper and the layer thickness of the sealing compound and at the same time that of the finished sealing membrane are controlled by the distance between the two rollers. The area on the two long sides, which is used to glue the sealing membrane during the later overlapping laying, is obtained in that the film does not reach the edge on each side, but is replaced by the removable silicone paper.

The accompanying drawings are intended to illustrate the invention; show it
  • FIG. 1 shows a perspective sectional illustration of the sealing membrane according to the invention,
  • Figure 2 shows a section through two overlapping sealing sheets according to another embodiment of the invention.

Die Dichtungsbahn der Figur 1 besteht aus einer selbstklebenden Dichtungsmasse 11 zwischen zwei Folien 12 und 13. Die obere Folie 12 reicht nicht bis zur Längsseite 17, so daß im Bereich dieser Seite in Längserstreckung ein Streifen der selbstklebenden Dichtungsmasse frei liegt. In ähnlicher Weise reicht die untere Folie 13 nicht bis zu der gegenüberliegenden Längsseite 16, so daß im Bereich dieser Seite an der Unterseite ein freiliegender selbstklebender Bereich vorhanden ist. Die selbstklebenden Bereiche an den beiden Seiten auf der oberen bzw. unteren Fläche der Dichtungsbahn sind jeweils mit einer abziehbaren Schutzfolie (z.B. aus Silikonpapier) 14 bzw. 15 abgedeckt, welche beim Verlegen der Bahnen entfernt werden. Die Schutzfolie steht vorzugsweise seitlich etwas über, damit sie sich leichter entfernen läßt.1 consists of a self-adhesive sealant 11 between two films 12 and 13. The upper film 12 does not extend to the long side 17, so that a strip of the self-adhesive sealant is exposed in the area of this side in the longitudinal direction. Similarly, the lower film 13 does not extend to the opposite longitudinal side 16, so that an exposed self-adhesive area is present in the area of this side on the underside. The self-adhesive areas on both sides on the upper and lower surface of the waterproofing membrane are each covered with a removable protective film (e.g. made of silicone paper) 14 and 15, which are removed when the membranes are laid. The protective film preferably protrudes slightly from the side so that it can be removed more easily.

Beim überlappenden Verlegen der Bahnen liegt die Seite 16 über der Seite 17, so daß die von den Folien 12 bzw. 13 nicht abgedeckten Bereiche der selbstklebenden Dichtungsmasse 11 unmittelbar aufeinandertreffen und zu einer homogenen, dauerhaften und wasserdichten Verbindung führen. Wie Figur 2 zeigt, wird eine voll befriedigende Verbindung schon bei einer Überlappung der Bahnen erreicht, bei welcher die klebenden Schichten zu einem wesentlichen Teil direkt aufeinanderliegen, zum Teil aber auch eine Verklebung zwischen Klebeschicht und Folie stattfindet.When the sheets are laid overlapping, the side 16 lies above the side 17, so that the areas of the self-adhesive sealant 11 not covered by the foils 12 or 13 meet directly and lead to a homogeneous, permanent and watertight connection. As FIG. 2 shows, a completely satisfactory connection is achieved even when the webs overlap, in which the adhesive layers lie directly on top of one another to a large extent, but in some cases there is also an adhesive bond between the adhesive layer and the film.

Die den Folien 12 und 13 gegenüberliegenden Folien 13' und 12' lassen bei der in Figur 2 gezeigten Ausführungsform einen schmalen Streifen 18,19 der Dichtungsmase 11 frei. Dadurch wird ein Fixierungsrand gebildet, der die Verlegung der Bahnen beträchtlich erleichtert. Der Fixierungsrand 19 an der Unterseite bewirkt eine Haftung am Untergrund, während der Fixierungsrand 18 an der Oberseite die Festlegung weiterer Schichten bewirkt. Ein Verkleben des Materials im Bereich der Fixierungsränder bei Transport und Lagerung wird durch die Schutzfolien 14,15 verhindert.In the embodiment shown in FIG. 2, the films 13 'and 12' opposite the films 12 and 13 leave a narrow strip 18, 19 of the sealing lug 11 free. This creates a fixing edge, which considerably facilitates the laying of the sheets. The fixing edge 19 on the underside causes adhesion to the substrate, while the fixing edge 18 on the upper side causes additional layers to be fixed. The protective films 14, 15 prevent the material from sticking in the area of the fixing edges during transport and storage.
