- the flexible sealing tape that crosses the ridge and is air-permeable and air-permeable is used, which rests with its edge parts glued to the ridges adjacent to the roof covering, so that it can be laid in the simplest way.
- the ridge pans which cross over the ridges and therefore also overlap the sealing tape, and which sit on the pans while forming a protrusion over the web formed on the ridge tiles, form a comparatively large free space above the sealing tape, from which a correspondingly large throughput of incoming outside air results, which, due to its correspondingly high suction effect, leads to improved ventilation.

Description
Die Erfindung betrifft ein Firstlüftungssystem für Satteldächer, deren profilierte Pfannen verwendende Pfanneneindeckung mit firstangrenzenden Dachpfannen, die vor Kopf mit einem sich über die Breite der Pfannen erstreckenden, an deren Innenseite in die Pfannensenke/n auslaufenden Steg unter Aussparung des die angrenzende Pfanne überdeckenden Kupplungsbereichs versehen sind, von einer von der Traufe bis zur First durchgängigen Isolierung unter Belassung eines Zwischenraumes unterfangen ist, mit einem sich über die Länge der First erstreckenden Firstlüftungselement in Gestalt eines luftdurchlässigen, wasserabweisenden, mit seinen Längsrandteilen gegen die an die firstangrenzenden Dachpfannen angeformten Stege zur Anlage kommenden flexiblen, mit den Stegen eine Klebverbindung eingehenden Dichtungsbandes, das mittig von der Firstlatte unterfangen ist.The invention relates to a ridge ventilation system for saddle roofs, the profiled pans of which are covered with ridge-adjoining roof tiles, which are provided in front with a ridge that extends across the width of the pans and on the inside of which runs into the pan sink (s) with the exception of the coupling area covering the adjacent pan , underpinned by insulation from the eaves to the ridge, leaving a space in between, with a ridge ventilation element extending over the length of the ridge in the form of an air-permeable, water-repellent, with its longitudinal edge parts against the webs formed on the ridge-adjoining roof tiles , with the webs an adhesive connection of incoming sealing tape, which is underpinned in the middle by the ridge batten.
Bei der Eindeckung von Satteldächem mit Dachpfannen ist heute die Isolierung der Dacheindeckung durch die Dachpfannen unter Belassung eines Zwischenraumes hinterfangende, sich von der Traufe bis in den Firstbereich erstreckende Isolierbahnen die Regel. Diese Isolierung macht eine Ent- und Belüftung des Zwischenraums zwischen den Dachpfannen und der Isolierung erforderlich. Hierfür sind sich über die Länge der First erstreckende, sich an der Firstlatte und an den an die Firstlatte angrenzenden Pfannenreihen der Dacheindeckung abstützende Firstlüftungselemente vorgesehen, die von den Firstpfannen übergriffen sind. Als Firstlüftungselemente kommen mit Luftdurchtrittsöffnungen versehene Kunststofformteile zum Einsatz, die sich an den firstangrenzenden Pfannenreihen der Dacheindeckung über ihren Längsrandteilen zugeordnete Schaumstoffstreifen abstützen. Dabei kann es sich dann auch um zweiteilige Elemente handeln. An diesem Firstlüftungselement stützen sich die Firstpfannen ab (DE-A-30 23 083). Neuerdings kommen dann auch einerseits wasserundurchlässige und andererseits luftdurchlässige flexible Dichtungsbänder zur Anwendung, die auch wieder den Zwischenraum zwischen der Firstlatte und den firstangrenzenden Dachpfannen überdeckend mit ihren Längsrändern gegen die firstangrenzenden Pfannenreihen der Dacheindeckung zur Anlage kommen. In diesem Fall sitzt die Firstpfanne auf der Firstlatte auf (EP-A-0 341 343 und DE-A-40 01 766). Nach dem Stand der Technik bedarf es beim Einsatz von Auswölbungen und Senken ausbildend profilierten Dachpfannen der Anpassung der Längsrandteile der Firstlüftungselemente an die sich aus der Profilierung der Dachpfannen ergebenden Konturen. Daraus resultiert bei Kunststofformteilen, die sich über Schaumstoffstreifen an den firstangrenzenden Pfannen der Dacheindeckung abstützen, eine unterschiedliche Deformierung der Schaumstoffstreifen, wodurch die Standzeit der Schaumstoffstreifen beeinträchtigt wird. Auch läßt die gewünschte Ausbildung einer Wassersperre durch die Schaumstoffstreifen zu wünschen übrig. Kommen einerseits wasserundurchlässige und andererseits luftdurchlässige flexible Dichtungsbänder als Firstlüftungselement zum Einsatz, bedarf es besonderer Maßnahmen für die Anpassung der gegen die firstangrenzenden Pfannen zur Anlage kommenden Randbereiche des Dichtungsbandes an die Pfannenkonturen. Sitzen die Firstpfannen ausschließlich auf der Firstlatte auf, resultiert daraus ein vergleichsweise kleiner Freiraum zwischen Firstpfannen und Firstlüftungselement mit einem dementsprechend geringen Durchsatz anströmender Außenluft zu Lasten der Entlüftung.When covering saddle roofs with roof tiles, the insulation of the roof covering by the roof tiles is now the rule, leaving an intervening gap between the eaves and the ridge area. This insulation makes ventilation of the space between the roof tiles and insulation required. For this purpose, ridge ventilation elements are provided which extend over the length of the ridge and are supported on the ridge batten and on the rows of tiles of the roof covering which adjoin the ridge batten and which are overlapped by the ridge pans. Plastic molded parts with air passage openings are used as ridge ventilation elements, which are supported on the ridge-adjacent pan rows of the roof covering via their longitudinal edge parts assigned to them. It can then be a two-part element. The ridge pans are supported on this ridge ventilation element (DE-A-30 23 083). Recently, waterproof sealing tapes have been used on the one hand, and on the other hand air-permeable, they also come into contact with the space between the ridge slat and the ridge-adjoining roof tiles with their longitudinal edges against the ridge-adjacent tile rows of the roof covering. In this case, the ridge pan sits on the ridge batten (EP-A-0 341 343 and DE-A-40 01 766). According to the state of the art, when using bulges and depressions which form profiled roof tiles, the longitudinal edge parts of the ridge ventilation elements have to be adapted to the contours resulting from the profiling of the roof tiles. This results in a different deformation of the foam strips in the case of plastic molded parts which are supported by foam strips on the ridges adjacent to the roof covering, which affects the service life of the foam strips. The desired formation of a water barrier through the foam strips leaves something to be desired. If, on the one hand, water-impermeable and, on the other hand, air-permeable flexible sealing tapes are used as the ridge ventilation element, special measures are required for adapting the edge areas coming into contact with the ridge-adjoining pans of the sealing tape to the pan contours. If the ridge pans only sit on the ridge batten, this results in a comparatively small free space between the ridge pans and the ridge ventilation element with a correspondingly low throughput of incoming outside air at the expense of ventilation.
Ausgehend vom vorbeschriebenen Stand der Technik liegt der Erfindung die Aufgabe zugrunde, die Eindeckung des Firstbereichs von isolierten und belüfteten Satteldächem unter Optimierung der Entlüftung unproblematischer zu gestalten.Starting from the above-described prior art, the object of the invention is to make the roofing of the ridge area of insulated and ventilated gable roofs less problematic while optimizing the ventilation.
Die Aufgabe wird mit einem gattungsgemäßen Firstlüftungssystem gelöst, daß dadurch gekennzeichnet ist, daß das Dichtungsband unter Belassung eines durchgängigen Zwischenraumes von der einen Seite des Daches zur anderen Seite des Daches hin von Firstpfannen übergriffen ist, die fußseitig unter Ausbildung eines Überstandes über den an die firstangrenzenden Dachpfannen angeformten Steg auf den Pfannen aufsitzen.The object is achieved with a ridge ventilation system of the generic type, characterized in that the sealing tape is overlapped by ridge pans, leaving a continuous space from one side of the roof to the other side of the roof, forming a protrusion on the foot side to the one adjacent to the ridge Fit the roof tiles formed on the pans.
Die fristangrenzend zum Einsatz kommenden Spezialpfannen mit dem kopfseitig an sie angeformten Steg bilden im Verlegungszustand eine sich durchgehend über die Länge der First erstreckende plane Auflage für die Längsrandteile des firstüberdeckenden Firstlüftungselements aus, die die Zuordnung des Firstlüftungselementes erleichtert und die in diesem Bereich gewünschte Dichtfunktion des Systems gegen Schlagwasser verbessert. Das zum Einsatz kommende, die Firstlatte übergreifende einerseits wasserundurchlässige und andererseits luftdurchlässige flexible Dichtungsband, das mit seinen Randteilen auf den an der Dacheindeckung firstangrenzend ausgebildeten Auflagen, damit verklebt aufliegt, läßt sich auf einfachste Weise verlegen. Die firstübergreifenden und damit dann auch das Dichtungsband übergreifenden Firstpfannen, die unter Ausbildung eines Überstandes über den an die firstangrenzenden Dachpfannen angeformten Steg auf den Pfannen aufsitzen, bilden einen vergleichsweise großen Freiraum oberhalb des Dichtungsbandes aus, aus dem ein dementsprechend großer Durchsatz an anströmender Außenluft resultiert, die aufgrund ihrer dementsprechend hohen Sogwirkung im Ergebnis zu einer verbesserten Entlüftung führt. Der Überstand der Firstpfannen über den an die firstangrenzenden Dachpfannen angeformten Steg und damit dann auch über das unter ihm befindliche Dichtungsband, das also durch die Firstpfannen vollständig überdeckt ist, unterbindet zum einen die Einwirkung von die Standzeit des Dichtungsbandes beeinträchtigender UV-Strahlung auf das Band, zum andern wird auf diese Weise eine Beeinträchtigung des optischen Eindruckes der Dacheindeckung durch nach dem Stand der Technik überwiegend unter den Firstpfannen vorspringende Randbereiche der Firstlüftungselemente vermieden.When installed, the special pans with the ridge molded onto them on the head side form a flat support for the longitudinal edge parts of the ridge-covering ridge ventilation element that extends over the length of the ridge, which facilitates the assignment of the ridge ventilation element and the sealing function of the system desired in this area improved against blow water. The flexible sealing tape that crosses the ridge and is air-permeable and air-permeable is used, which rests with its edge parts glued to the ridges adjacent to the roof covering, so that it can be laid in the simplest way. The ridge pans, which cross over the ridges and therefore also overlap the sealing tape, and which sit on the pans while forming a protrusion over the web formed on the ridge tiles, form a comparatively large free space above the sealing tape, from which a correspondingly large throughput of incoming outside air results, which, due to its correspondingly high suction effect, leads to improved ventilation. The protrusion of the ridge tiles over the ridge formed on the ridge tiles and thus also over the sealing tape located below it, which is therefore completely covered by the ridge tiles, on the one hand prevents the effect of UV radiation on the tape which affects the service life of the sealing tape, on the other hand, in this way, an impairment of the visual impression of the roof covering by edge areas of the ridge ventilation elements that protrude predominantly under the ridge pans is avoided.
Ausgestaltungen des neuen Lüftungssystems ergeben sich aus den Unteransprüchen 2 bis 7. Springt der vor Kopf der Spezialpfanne vorgesehene Steg gegenüber dem Scheitel der Pfannenauswölbung/en zurück, resultiert daraus in wünschenswerter Weise ein noch größerer Eintrittsquerschnitt in den zwischen dem Firstlüftungselement und den Firstpfannen ausgebildeten Zwischenraum für die anströmende Außenluft. Ein stetiger Übergang des vor Kopf der Spezialpfanne vorgesehenen Steges in die Pfannensenke/n bildet in wünschenswerter Weise eine Leitfläche für die anströmende Außenluft aus. Um den Freiraum zwischen Dichtungsband und Firstpfanne nicht zu groß werden zu lassen, kann zwischen die Firstlatte und das Dichtungsband ein über die Firstlatte vorspringender formstabiler gelochter Kunststoffstreifen eingefügt sein.Refinements of the new ventilation system result from subclaims 2 to 7. If the web provided in front of the head of the special pan jumps back against the apex of the pan bulge / s, this desirably results in an even larger inlet cross section in the space formed between the ridge ventilation element and the ridge pans the incoming outside air. A continuous transition of the web provided in front of the head of the special pan into the pan sink / s desirably forms a guide surface for the incoming outside air. In order not to allow the space between the sealing tape and the ridge pan to become too large, a dimensionally stable perforated plastic strip projecting over the ridge bar can be inserted between the ridge batten and the sealing tape.
Die in den in den Dachpfannen ausgebildeten Rinnen anströmende Außenluft tritt in den zwischen dem firstübergreifenden, den Zwischenraum zwischen der Dacheindeckung und der Dachisolierung gegen den Zutritt von mit der anströmenden Außenluft mitgerissenem Wasser im Firstbereich abschirmenden wasserdichten Dichtungsband und den das Dichtungsband überdeckenden Firstpfannen ausgebildeten Zwischenraum ein und verläßt diesen Bereich auf der von der anströmenden Außenluft abgekehrten Seite der First, Die das Dichtungsband überstreichende Außenluft saugt im Bereich zwischen der Dacheindeckung und der Dachisolierung befindliche Luft durch die von ihr ausgeübte Sogwirkung durch das luftdurchlässige Dichtungsband an und ent- sowie belüftet diesen Bereich somit. Die Wasserdichtigkeit des Dichtungsbandes sichert also den Bereich zwischen Isolierung und Dacheindeckung gegen den Zutritt von durch die anströmende Außenluft mitgerissenen Wasserpartikeln. Der Zutritt von Schlagwasser zum unterhalb der Firstpfannen ausgebildeten Zwischenraum wird durch die an den firstangrenzenden Spezialpfannen ausgebildete Wassersperre blockiert.The outside air flowing in the gutters formed in the roof tiles enters and enters the space between the ridge-covering, the space between the roof covering and the roof insulation against the access of water-tight sealing tape shielding with water flowing in with the incoming outside air in the ridge area and the space between the ridge tiles covering the sealing tape leaves this area on the side of the ridge facing away from the incoming outside air, the outside air sweeping over the sealing tape sucks air in the area between the roof covering and the roof insulation due to the suction effect it exerts through the air-permeable sealing tape and thus ventilates and ventilates this area. The watertightness of the sealing tape thus secures the area between the insulation and the roof covering against the entry of water particles entrained by the incoming outside air. The access of blow water to the one below the ridge pans The space is blocked by the water barrier formed on the special pans adjacent to the ridge.

Die Pfanne 11 in den Figuren 1 und 2 ist zwei Auswölbungen 111, 111' ausbildend profiliert, wobei die vollständige Eingrenzung der einen (112) der an die Auswölbungen angrenzenden Senken 112, 112' durch den den Kupplungsbereich 113 überdeckenden Randbereich der in der Pfannenreihe folgenden Pfanne 11 erfolgt. Mit der an der Unterseite der Pfanne 11 angeformten Nase 116 (Fig. 2) wird die Pfanne an der firstangrenzenden Dachlatte 22 (Fig. 4 und 5) abgehängt. Die fußseitige Profilierung 117 dient der Aufnahme von Dichtungsschnüren oder dergleichen. Bei dieser Spezialpfanne ist vor Kopf der Pfanne 11 an die Pfanne ein sich über deren Breite unter Aussparung des Kupplungsbereichs 114 erstreckender Steg 118 angeformt, der bei der Ausführungsform der Pfanne nach den Figuren 1 und 2 gegenüber den Scheiteln 1111 der Pfanne 11 geringfügig zurückspringt (Pfeil 119 in Figur 1) und dessen plane Außenseite 1181 nach der von der Pfanne abgekehrten Seite hin geringfügig einfällt (Pfeil 121 in Figur 1). Bei der Ausführungsform der Pfanne nach Figur 3 verläuft die Außenseite 1181 des Steges 118' im Niveau der Pfannenscheitel 1111. Der Steg 118 bzw. 118' bildet eine Auflagefläche für ein firstüberdeckendes Dichtungsband, er übt an der Innenseite in die Senken 112, 112' auslaufend (1182) weitergehend die Funktion einer Wassersperre aus.The
Die Figuren 4 bis 6 verdeutlichen das neue Lüftungssystem. Bei den mit ihren Nasen 116 an den firstangrenzenden Dachlatten 22 abgehängten Pfannen 11 bzw. 11' handelt es sich um Spezialpfannen der in den Figuren 1 bis 3 aufgezeigten Ausgestaltung. Charakteristisch für diese Spezialpfannen ist der kopfseitig an sie angeformte Steg 118, aus dem im Verlegungszustand der Pfannen eine sich über die Länge der First erstreckende Auflage 1181 resultiert. Das firstüberdeckende, von der Firstlatte 21 unterfangene einerseits luftdurchlässige und andererseits wasserabweisende Dichtungsband 41 liegt mit seinen Randteilen 411 auf den von den firstangrenzenden Dachpfannen 11 bzw. 11' ausgebildeten längs der Firstlatte 21 verlaufenden Auflagen 1181 auf und geht mit diesen Auflagen 1181 eine Klebverbindung ein (42). Die Verlegung des Dichtungsbandes 41 erweist sich als denkbar unkompliziert. Das Dichtungsband 41 wird übergriffen von den Firstpfannen 12, die mit ihren Randteilen auf den firstangrenzenden Dachpfannen 11 bzw. 11' unter Belassung eines Zwischenraumes 61 zwischen Dichtungsband 41 und Firstpfannen 12 aufsitzen. Wie das insbesondere aus den Figuren 5 und 6 zu entnehmen ist, ist das Dichtungsband 41 durch die sie übergreifende Firstpfannen 12 vollständig gegen UV-Strahlung abgeschirmt, es ist dann auch der Sicht des Betrachters entzogen.Figures 4 to 6 illustrate the new ventilation system. The
Bei im Sinne des Pfeiles A in Figur 5 anströmender Außenluft wird diese auf die Dacheindeckung (11) auftreffend zum Zugang 611 zum zwischen dem Dichtungsband 41 und den Firstpfannen 12 ausgebildeten Zwischenraum 61 abgelenkt. Die in den Zwischenraum 61 zwischen dem Dichtungsband 41 und den Firstpfannen 12 gelangende Außenluft durchströmt diesen Zwischenraum 61 und verläßt ihn auf dem von der anströmenden Luft (Pfeil A') abgekehrten Seite des Daches durch den Ausgang 611'. Aufgrund der von der den Zwischenraum 61 zwischen dem Dichtungsband 41 und den Firstpfannen 12 durchströmenden Außenluft ausgeübten Sogwirkung wird zwischen der Dacheindeckung und der Dachisolierung befindliche Luft, also in dem Bereich 62 befindliche Luft durch das luftdurchlässige Dichtungsband 41 angesaugt (Pfeil B in Fig. 5) und zusammen mit der den Zwischenraum 61 durchströmenden Außenluft durch den Ausgang 611' abgeführt (Pfeil B'). Einher geht damit ein Nachströmen von Frischluft in den Bereich zwischen der Dacheindeckung und der Dachisolierung von der Traufe her. Der Bereich zwischen der Dacheindeckung und der Dachisolierung unterliegt somit einer ständigen Entlüftung und damit einhergehender Belüftung, wodurch sichergestellt wird, daß es in diesem Bereich nicht zu Nässeschäden kommt. Die wasserabweisende Einstellung des Dichtungsbandes 41 verhindert dabei, daß von der anströmenden Außenluft mitgerissene Wasserpartikel über den Firstbereich in den Bereich zwischen der Dacheindeckung und der Dachisolierung gelangen.When the outside air flows in the direction of arrow A in FIG. 5, it hits the roof covering (11) and is deflected to the
Wenngleich der Zwischenraum 61 zwischen dem Dichtungsband 41 und den Firstpfannen 12 möglichst groß ausgelegt werden soll, um einen möglichst großen Außenluftdurchsatz zu ermöglichen, so ist dieser Zwischenraum doch zwecks Unterbindung des Nisten von Vögeln in diesem Zwischenraum zu begrenzen. Dem kann beispielsweise dadurch Rechnung getragen werden, daß zwischen Firstlatte 21 und Dichtungsband 41 eine über die Firstlatte 21 vorspringend gelochte Platte 211 eingefügt wird.Although the
