Abstract

The insulated roof, with visible rafters, has a two part insulation with a relatively soft insulating panel fitted over the outside of the rafter and covered by strips of thicker, firmer insulation fitted over the top and covered by the tile battens. The strips are fitted between spacers on the rafters and are covered by a waterproofing foil before fitting the tile battens. The insulation is secured by ties through both layers. The edges of the roof have the waterproofing tucked over the edges. Both insulating layers are made of mineral wool. The fibres of the lower panel run parallel to the roof while those of the thicket cladding run normal to the roof.

Description

Die vorliegende Erfindung betrifft Dämmstoffelemente aus Mineralwolle für die Übersparrendämmung von Dächern, wie durch den Oberbegriff des Patentanspruches 1 beschrieben, sowie ein Verfahren zur Übersparrendämmung unter Verwendung dieses Dämmstoffelements.The present invention relates to insulation elements made of mineral wool for the Over-rafter insulation of roofs, as by the preamble of the claim 1 described, as well as a method for over rafter insulation Use of this insulation element.

Bei dem Ausbau von Steildächern besteht bei einem großen Teil der Bauherren heutzutage der Wunsch nach einer rustikalen Erscheinung des Dachausbaus zur Förderung der Wohnlichkeit. Besonders beliebt ist diesbezüglich ein derartiger Dachausbau, bei dem die Sparren des Daches sowie die auf den Sparren angeordnete Verbretterung von innen sichtbar ist. Bei einer derartigen Dachausbauweise ist es daher erforderlich, um den heutigen Anforderungen hinsichtlich Wärmedämmung zu entsprechen, diese oberhalb der Sparren anzuordnen. A large part of the builders are involved in the removal of pitched roofs nowadays the desire for a rustic appearance of the loft conversion Promotion of homeliness. This is particularly popular in this regard Roof extension, in which the rafters of the roof as well as those arranged on the rafters Boarding is visible from the inside. With such a roof construction it is therefore necessary to meet today's thermal insulation requirements to correspond to arrange them above the rafters.

Eine diesbezüglich bekannte Vorgehensweise ergibt sich z.B. aus dem Dokument EP 0 682 161, in dem eine Dachunterstruktur offenbart ist, bei der auf einer Verbretterung der Sparren eine filmartige Dampfsperre sowie eine auf der Dampfsperre angeordnete Dämmstoffschicht vorgesehen ist, welche schließlich durch einen wasserabweisenden und diffusionsoffenen Film abgedeckt ist. Die Dämmstoffschicht ist aus stegartigen Streifen sowie von der Rolle abwickelbare Dämmstoffbahnen gebildet, die alternierend und spaltenfrei parallel zu einer Kante des Daches ausgelegt sind. Die Streifen weisen dabei eine große Kompressionsstabilität auf, so daß sie die durch eine lastabtragende Einrichtung für die oberhalb der Dämmstoffschicht angeordneten Dachteile eingeleiteten Lasten aufnehmen kann. Die Dämmstoffbahn ist dagegen rein dichtemäßig auf optimale Dämmeigenschaften ausgelegt. Das System hat sich in der Praxis bewährt, jedoch werden zur abschließenden Folienüberdeckung des Gesamtdaches, insbesondere bei Verältnissen mit starkem Wind, mehrere Personen benötigt.A procedure known in this regard results e.g. from the document EP 0 682 161, in which a roof substructure is disclosed, in which on a Boarding the rafters a film-like vapor barrier as well as one on the Vapor barrier arranged insulation layer is provided, which finally is covered by a water-repellent and permeable film. The The insulation layer is made of web-like strips and can be unwound from the roll Insulation sheets formed that alternate and gap-free parallel to one Edge of the roof are laid out. The stripes show great compression stability on so that it can be replaced by a load transfer device for the loads introduced above the insulation layer can record. The insulation sheet, on the other hand, is purely density-optimized Insulation properties designed. The system has proven itself in practice, however become the final foil covering of the entire roof, in particular in conditions with strong wind, several people needed.

Des weiteren ist aus dem Dokument DE 36 15 109 C2 ein Unterdach für mit Dacheindeckungsplatten eingedeckte Sparrendächer bekannt, welches aus Mineralfaser-Dämmplatten besteht, die auf einer auf den Dachsparren angeordneten und mit einer folienartigen Dampfsperre abgedeckten Schalung verlegt sind und die oberseitig jeweils mittels einer wasserabweisenden, trittfesten Kaschierlage abgedeckt sind. Die Kaschierlage steht an zwei einander benachbarten Plattenrändern seitlich über diese vor und überlappt die Ränder der Kaschierlagen der benachbarten Dämmplatte. Über der Dämmstoffschicht sind vom First zur Traufe sich erstreckenden Konterlatten angeordnet, welche wiederum Dachlatten tragen, die zur Aufnahme der Dacheindeckungsplatten vorgesehen sind. Das hier beschriebene Unterdach hat sich ebenfalls in der Praxis bewährt ist jedoch aufgrund des hohen Materialanteils zur Erreichung einer ausreichenden Trittfähigkeit relativ teuer.Furthermore, from document DE 36 15 109 C2 is a sub-roof for with Rafter roofs covered, which are made of mineral fiber insulation boards exists, which is arranged on a rafters and are laid with a foil-like formwork covered formwork and the top of each with a water-repellent, non-slip liner are covered. The liner is on two adjacent plate edges sideways over this and overlaps the edges of the lamination layers of the neighboring insulation board. Above the insulation layer are from the ridge to the eaves extending counter battens arranged, which in turn carry roof battens, which are intended to accommodate the roofing slabs. This one Sub-roof described has also proven itself in practice, however, is due to the high proportion of material to achieve sufficient pedaling ability relative expensive.

Die Aufgabe der vorliegenden Erfindung ist es, eine Wärmedämmung von Dächern oberhalb der Sparren vorzusehen, welche unter Beibehaltung der Vorteile der vorgenannten Systeme einfach und schnell auch von ungeübtem Personal verlegt und nach Möglichkeit kostengünstiger ist.The object of the present invention is to provide thermal insulation of roofs to be provided above the rafters, while maintaining the advantages of the aforementioned systems easily and quickly even by inexperienced personnel relocated and, if possible, less expensive.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst, wobei zweckmäßige Ausführungsformen durch die Unteransprüche gekennzeichnet sind.This object is achieved by the characterizing features of the claim 1 solved, expedient embodiments characterized by the subclaims are.

Vorgesehen ist ein Dämmstoffelement aus Mineralwolle für die Übersparrendämmung von Dächern sowie ein Verfahren zur Übersparrendämmung unter Verwendung dieses Dämmstoffelements, das auf der Verbretterung der Dachkonstruktion parallel zur Dachrandkante verlaufend anzuordnen ist und aus abwechselnd schmalen Dämmstoffstreifen sowie dazwischen angeordnete Dämmstoffplatten besteht. Die Dämmstoffstreifen sind dabei bezüglich der dazwischen angeordneten Dämmstoffplatten relativ druckfest ausgebildet und bestehen vorzugsweise aus einem Abschnitt einer gestauchten Dämmstoffplatte, der in der Form eines Lamellensteges abgeschnitten wurde. Die so gebildeten Dämmstoffstreifen sind dabei vorzugsweise so in der Wärmedämmung des Daches angeordnet, daß ihre Faserrichtung im wesentlichen rechtwinklig zur Erstreckung der Dachfläche verläuft. Die zwischen den Dämmstoffstreifen angeordneten Dämmstoffplatten sind dahingegen im wesentlichen auf optimale Wärmedämmeigenschaften ausgelegt und bezüglich der Dämmstoffstreifen relativ weich. Die Faserrichtung der Dämmstoffplatten dagegen verläuft im wesentlichen parallel zu der zu dämmenden Dachfläche. Aufgrund der höheren Festigkeit der Dämmstoffstreifen, welche vornnehmlich aufgrund der stehenden Faserausrichtung erreicht wird, können diese trotz ihrer schmalen Ausbildung eine hohe Druckbelastung aufnehmen, wodurch die Wärmedämmung bzw. das mit der Wärmedämmung versehene Dach begehbar ist. Die zwischen den Dämmstoffstreifen angeordneten Dämmstoffplatten hingegen brauchen dagegen nur bezüglich ihrer Wärmedämmungsfunktion optimiert sein, so daß hierdurch Material und somit Kosten eingespart werden können. A mineral wool insulation element is provided for the over-rafter insulation of roofs as well as a method for insulation above rafters Use of this insulation element on the planking of the roof structure is to be arranged parallel to the edge of the roof and alternating narrow strips of insulation and insulation panels arranged in between consists. The insulation strips are in between arranged insulation boards are relatively pressure-resistant and preferably exist from a section of a compressed insulation board, which in the Form of a lamella web was cut off. The insulation strips thus formed are preferably arranged in the thermal insulation of the roof that their fiber direction is substantially perpendicular to the extension the roof area runs. The arranged between the insulation strips Insulation boards, on the other hand, are essentially geared towards optimal thermal insulation properties designed and relatively soft with regard to the insulation strips. The In contrast, the grain of the insulation boards runs essentially parallel to the roof surface to be insulated. Due to the higher strength of the insulation strips, which mainly due to the standing fiber orientation is achieved, these can withstand a high pressure load despite their narrow design record, whereby the thermal insulation or that with the thermal insulation provided roof is accessible. The between the insulation strips arranged insulation boards, however, only need with respect to their Thermal insulation function can be optimized, so that this material and thus Costs can be saved.

Nach Maßgabe der Erfindung sind die Länge der Dämmstoffstreifen sowie der Dämmstoffplatten aufeinander abgestimmt. An dem jeweiligen Dämmstoffstreifen ist darüber hinaus eine Folie befestigt, deren Länge so gewählt ist, daß sie auf einer Seite über die Länge des Dämmstoffstreifens vorsteht, und deren Breite derart gewählt ist, daß sie neben dem Dämmstoffstreifen, an dem sie befestigt ist, zusätzlich auch die angrenzend an dem Dämmstoffstreifen angeordnete Dämmstoffplatte überdeckt sowie ein gewisses Maß über den freien Rand der Dämmstoffplatte vorsteht. Ausgebildet ist daher eine Anordnung aus Dämmstoffstreifen und angrenzend angeordneter Dämmstoffplatte, wobei diese Anordnung von einer Folie überdeckt ist, die an vorzugsweise zwei der vier Randkanten der zusammengesetzten Anordnung übersteht. Die Folie ist dabei vorzugsweise mit dem Dämmstoffstreifen verklebt, wobei auch nur eine Transportbefestigung vorgesehen sein kann, die lediglich sicherstellt, daß sich die Folie während des Transports nicht ablöst. Die Fixierung der Folie im montierten Zustand erfolgt dabei durch die Nebeneinanderanordnung sowie die daraus resultierende Druckbelastung der Folie zwischen den Dämmstoffplatten bzw. Dämmstoffstreifen, wenn die Folie um zumindest eine Kante der Dämmstoffstreifen herum gelegt ist. Darüber hinaus erfolgt nach der Verlegung der Dachziegel ohnehin keine Beanspruchung durch Windlasten, so daß die Anforderungen an die Befestigung der Folie an den Dämmstoffstreifen geringgehalten werden kann. Die über eine Längs- sowie eine Schmalseitenkante der aus Dämmstoffstreifen und Dämmwollplatte gebildeten Anordnung überstehenden Ränder der Folie sind vorzugsweise mit einem Kleber, weiterhin bevorzugt in der Art eine Klebebandes mit abziehbarer Abdeckung versehen. Auf diese Weise ist es möglich, mehrere aus einem Dämmstoffstreifen, einer Dämmstoffplatte sowie einer diese abdeckenden Folie gebildete Anordnungen zur Herstellung einer Wärmedämmung von Dächern oberhalb der Sparren auf der Verbretterung der Sparren nebeneinander anzuordnen, so daß die überstehenden Ränder der Folie jeweils über die nicht mit überstehenden Rändern der Folie versehene Randkanten der nebengeordneten Zusammensetzung aus Dämmstoffstreifen, Dämmstoffplatte und Folie überlappen und verliebt werden, so daß eine zusammenhängende Dämmstoffschicht erzielt wird, die bereits nach der Montage ein regendichtes Dach darstellt bis später die eigentliche Dacheindeckung mit z.B. Ziegeln erfolgt.According to the invention, the length of the insulation strips and the Insulation boards matched to one another. On the respective insulation strip is also attached a film, the length of which is selected so that it protrudes on one side over the length of the insulation strip and its width is chosen such that it is next to the strip of insulation to which it is attached, in addition also the insulation board arranged adjacent to the insulation strip covered and a certain amount over the free edge of the insulation board protrudes. An arrangement of insulating strips is therefore formed and adjacent insulation board, this arrangement of a film is covered, which preferably on two of the four edge edges of the composite Arrangement survives. The film is preferably with glued to the insulation strip, with only one transport attachment provided can be, which only ensures that the film during the Transport does not replace. The film is fixed in the assembled state thereby by the side-by-side arrangement and the resulting pressure load the film between the insulation boards or strips, if the film is placed around at least one edge of the insulation strips is. In addition, there is no stress after the roof tiles have been laid by wind loads, so that the requirements for fastening the Foil on the insulation strips can be kept low. The one Longitudinal and a narrow side edge of the insulation strips and wool panel Formed arrangement projecting edges of the film are preferred with an adhesive, further preferably in the manner of an adhesive tape removable cover. This way it is possible to make several out an insulation strip, an insulation board and one covering these Foil formed arrangements for the production of thermal insulation of roofs above the rafters on the planks of the rafters side by side to be arranged so that the protruding edges of the film are each not over the Edge edges of the neighboring ones provided with protruding edges of the film Overlap the composition of insulation strips, insulation panels and foil and fall in love, so that a coherent layer of insulation is achieved, which is a rainproof roof after assembly until later the actual roof covering with e.g. Bricks are made.

Die aus den Dämmstoffstreifen, den dazwischen angeordneten Dämmstoffplatten sowie der diese beiden überdeckenden Folie bestehenden Dämmelemente überlagernd ist eine vorzugsweise aus einer Lattung bestehende Konstruktion zum Abtrag der Lasten der Dachziegel oder anderer geeigneter Elemente zum Decken des Daches vorgesehen. Diese im folgenden auch als Tragekonstruktion bezeichnete Einrichtung zum Abtrag der Lasten der Dachziegel etc. ist zur Übertragung der Lasten auf die Sparren bzw. die darauf angeordnete Verbretterung durch geeignete Verbindungselemente, vorzugsweise Nägel oder insbesondere Schrauben, die beiderseitig mit Gewinde versehen sind, mit der Sparrenkonstruktion verbunden, so daß die Dämmstoffstreifen bzw. die Dämmstoffplatten zwischen der Verbretterung der Dachsparren sowie der über der Wärmedämmung angeordneten Tragekonstruktion eingeschlossen sind. Auf diese Weise wird ein definierter Lastabtrag erzielt, wodurch die Dämmstoffstreifen mit erhöhter Festigkeit schmal gehalten werden können, was wiederum dem Materialverbrauch zugute kommt.The from the insulation strips, the insulation panels arranged in between as well as overlying the insulation elements existing over these two covering foils is a preferably made of battens for removal the loads of the roof tiles or other suitable elements for covering of the roof.

Entsprechend Fig. 1 weist das Dämmstoffelement aus Mineralwolle nach der Erfindung einen Dämmstoffstreifen 1 auf, der in diesem Falle aus einer gestauchten Dämmstoffplatte besteht, die in Richtung des Faserverlaufes zu Plättchen bzw. Lamellen oder Lamellenstegen zerschnitten worden ist. Die Verwendung des Dämmstoffstreifens 1 erfolgt, wie in Fig. 1 dargestellt, so, daß der Faserverlauf des Dämmstoffstreifens 1 im wesentlichem senkrecht zu einer zu dämmenden Fläche liegt. Der Dämmstoffstreifen weist aufgrund seiner Materialstauchung eine höhere Dichte auf und ist gegenüber unverdichtetem Dämmstoffmaterial, wesentlich druckfester. Unmittelbar angrenzend an den Dämmstoffstreifen 1 ist, wie ebenfalls aus Fig. 1 ersichtlich, eine Dämmstoffplatte 2 angeordnet, deren Länge der Länge des Dämmstoffstreifens 1 entspricht. Das Kompendium aus Dämmstoffstreifen 1 und Dämmstoffplatte 2 wird von einer Folie 3 komplettiert, die vorzugsweise an dem Dämmstoffstreifen 1 befestigt ist und eine Länge sowie eine Breite aufweist, daß sie, wie in Fig. 1 dargestellt, über eine Schmal- sowie eine Längskante der Kombination aus dem Dämmstoffsteg und Dämmstoffplatte übersteht, wobei die überstehenden Ränder der Folie 3 mit den Bezugszeichen 4 und 5 versehen sind. Zur besseren Darstellung sind Teile des Dämmstoffelements in Fig. 2 in aufgelöster Stellung dargestellt, in der man sieht, daß die Folie 3 an dem im Kompendium von der Dämmstoffplatte abgewandten Seite des Streifens 1 nach Umschlagen befestigt, insbesondere verklebt ist, so daß die Folie auch den Dämmstoffstreifen 1 oben überdeckt.1, the insulating element made of mineral wool according to the invention an insulation strip 1, which in this case consists of a compressed Insulation board exists, which in the direction of the fiber course to platelets or slats or lamella webs has been cut. The usage the insulation strip 1, as shown in Fig. 1, so that the grain the insulation strip 1 essentially perpendicular to one to be insulated Area. The insulation strip shows due to its material compression has a higher density and is compared to non-compressed insulation material, much more pressure resistant. Immediately adjacent to the insulation strips 1, as can also be seen from FIG. 1, an insulation board 2 is arranged, whose length corresponds to the length of the insulation strip 1. The compendium of insulation strip 1 and insulation plate 2 is completed by a film 3, which is preferably attached to the insulation strip 1 and a length and has a width that it, as shown in Fig. 1, over a narrow and a longitudinal edge of the combination of the insulating web and insulating board protrudes, the protruding edges of the film 3 with the reference numerals 4 and 5 are provided. Parts of the Insulating element shown in Fig. 2 in the released position, in which one sees that the film 3 on the facing away from the insulation board in the compendium Side of the strip 1 attached after folding, in particular glued is so that the film also covers the insulation strip 1 above.

Wie sich aus Fig. 3 ergibt, erfolgt die Verlegung der zusammengesetzten Dämmelemente derart, daß ausgehend von derjenigen Ecke der zu dämmenden Dachfläche, die der Ecke der zusammengesetzten Dämmelemente entspricht, wo die überlappenden Ränder der Folie 4, 5 aufeinandertreffen, im vorliegenden Fall unten rechts, die Dämmelemente bis zu der diagonal gegenüberliegenden Ecke der zu dämmenden Dachfläche verlegt werden. Die überstehenden Reste der zusammengesetzten Dämmelemente am Ende der zu dämmenden Dachfläche können bei dieser Art der Verlegung auf die geeignete Breite und Länge zugeschnitten werden, so daß eine exakte Anpassung an die zu dämmende Dachfläche erfolgt. Wie ebenfalls aus Fig. 3 ersichtlich, sind die aus den Dämmstoffstreifen 1 sowie den Dämmstoffplatten 2 und den Folien 3 zusammengesetzten Dämmelemente versetzt zueinander positioniert. Ebenso ist aber auch eine bezüglich der Dachränder ausgerichtete Verlegung der zusammengesetzten Dämmelemente von unten nach oben möglich. Die Verlegeart eignet sich insbesondere für Steildächer, insbesonde Dächer mit einer Dachneigung größer 30°, da dies eine Verlegung von einer auf das Steildach aufgelegten Leiter aus ermöglicht. Hierbei werden die Dämmelemente ausgehend von einem Dachrand von einer Leiter aus von unten nach oben in einer ersten Reihe und dann benachbart wieder von unten nach oben in einer zweiten Reihe und so weiter bis zum anderen Dachrand hin verlegt. In Verlegeposition überlappen die überstehenden Folienränder 4 und 5 die jeweils angrenzend angeordneten zusammengesetzten Dämmelemente, wobei die unteren Seiten der überstehenden Folienränder 4 und 5 mit einem Kleber versehen sind, vorzugsweise mit einem Abzugstreifen versehen, so daß sich letztendlich eine geschlossene Isolationsfläche ergibt, die durch die modulartigen zusammengesetzten Dämmelemente jedoch einfach, schnell und kostengünstig erstellt werden kann.As can be seen from FIG. 3, the composite insulation elements are laid such that, starting from that corner of the roof surface to be insulated, which corresponds to the corner of the composite insulation elements, where the overlapping edges of the film 4, 5 meet, in the present case bottom right, the insulation elements up to the diagonally opposite corner the roof surface to be insulated. The remaining remnants of the compound Insulation elements at the end of the roof surface to be insulated with this type of installation cut to the appropriate width and length be, so that an exact adjustment to the roof surface to be insulated takes place. As can also be seen from FIG. 3, those from the insulation strips 1 and the insulation panels 2 and the foils 3 composite insulation elements positioned offset to each other. But there is also one regarding the Laying of the composite insulation elements aligned to the roof edges possible from bottom to top. The type of installation is particularly suitable for steep roofs, in particular roofs with a roof pitch greater than 30 °, since this is a relocation from a ladder placed on the pitched roof. Here are the insulation elements starting from a roof edge from a ladder from bottom up in a first row and then adjacent again from below up in a second row and so on to the other edge of the roof relocated. In the laying position, the protruding film edges 4 and 5 overlap the respectively arranged composite insulation elements, whereby the lower sides of the protruding film edges 4 and 5 with an adhesive are provided, preferably provided with a trigger strip, so that ultimately a closed insulation surface results from the modular composite Insulation elements, however, created easily, quickly and inexpensively can be.
