Description
La présente invention concerne le domaine du bâtiment, notamment l'étanchéification et l'isolation de toitures, et a pour objet une membrane pare-vapeur, ainsi qu'un complexe isolant et étanchéifiant ou d'étanchéité comprenant notamment une telle membrane.The present invention relates to the building sector, in particular waterproofing and insulation of roofs, and has for object a vapor barrier membrane, as well as an insulating and sealing complex or sealing comprising in particular such a membrane.
Habituellement, et notamment sur les toitures acier, les couches de revêtement isolantes et d'étanchéité sont fixées sur les toitures par l'intermédiaire de fixations mécaniques traversant la couche isolante et, le cas échéant, une partie de la membrane pare-vapeur placée sous l'isolant et sur le support acier.Usually, and especially on steel roofs, the layers of insulating and waterproofing coatings are fixed on the roofs by through mechanical fasteners passing through the insulating layer and, the if necessary, part of the vapor barrier membrane placed under the insulation and on the steel support.
Toutefois, une telle fixation entraíne dans le cas de locaux à forte ou très forte hygrométrie des phénomènes de condensation dans la couche isolante et nécessite la prise de précaution particulière.However, such a fixation entails in the case of premises to high or very high humidity of the phenomena of condensation in the insulating layer and requires special care.
Il en résulte généralement une diminution conséquente des propriétés de ladite couche isolante et à terme une détérioration de cette couche.This generally results in a significant decrease in properties of said insulating layer and ultimately a deterioration of this layer.
Pour tenter de pallier cet inconvénient trois solutions ont été proposées.To try to overcome this drawback, three solutions have been proposed.
La première consiste à réaliser la couche isolante en un matériau insensible à l'humidité, tel que par exemple le verre cellulaire, mais elle entraíne un surcoût matière important.The first consists in making the insulating layer in one material insensitive to humidity, such as for example cellular glass, but it results in a significant additional material cost.
La deuxième solution consiste à étanchéifier, vis à vis des remontées de vapeur, les éléments constitutifs supports de la toiture, tels que par exemple des tôles d'acier nervurées, au niveau de leurs zones de chevauchement et au niveau des orifices de passage des moyens de fixation (vis ou analogues). La mise en oeuvre de cette solution est délicate à gérer sur site et fastidieuse dans son application.The second solution consists in sealing, with respect to rising steam, the supporting elements of the roof, such as for example ribbed steel sheets, at their areas of overlap and at the orifices of passage of the fixing means (screws or the like). The implementation of this solution is difficult to manage on site and tedious in its application.
La troisième solution proposée consiste à mettre en place entre les éléments constitutifs supports de toiture et la couche isolante une couche pare-vapeur, destinée à éviter la formation d'eau de condensation dans l'isolant en formant une barrière entre ce dernier et l'intérieur du bâtiment susceptible de présenter une atmosphère chargée en vapeur d'eau.The third solution proposed is to set up between the roof support components and the insulating layer a layer vapor barrier, intended to prevent the formation of condensation water in the insulation by forming a barrier between the latter and the interior of the building likely to present an atmosphere charged with water vapor.
Les couches pare-vapeur sont généralement de deux types, à savoir, un platelage en tôles minces revêtues d'une membrane bitumineuse ou une membrane bitumineuse disposée directement sur les tôles d'acier nervurées.Vapor barrier layers are generally of two types, know, a deck of thin sheets coated with a bituminous membrane or a bituminous membrane placed directly on the steel sheets ribbed.
Néanmoins, le premier type de pare-vapeur entraíne un surcoût important et un surpoids pour l'ouvrage considéré et nécessite des travaux d'étanchéification additionnels pour aboutir à une couche pare-vapeur parfaitement étanche à la vapeur d'eau.However, the first type of vapor barrier involves an additional cost important and overweight for the considered work and requires work additional sealing to achieve a vapor barrier layer perfectly waterproof to water vapor.
En outre, le second type de pare-vapeur présente une résistance mécanique limitée, notamment au droit des nervures des tôles.In addition, the second type of vapor barrier has resistance limited mechanics, especially at the level of the ribs of the sheets.
De plus, la membrane bitumineuse nécessite, dans les deux cas précités, l'intégration, dans son épaisseur, d'une couche continue étanche à la vapeur, en particulier d'une feuille d'aluminium, pouvant supporter les températures d'enduction bitumineuse.In addition, the bituminous membrane requires, in both cases mentioned above, the integration, in its thickness, of a continuous layer impervious to steam, particularly aluminum foil, which can withstand bituminous coating temperatures.
Or, ces couches d'aluminium présentent une résistance mécanique limitée et sont extrêmement sensibles aux plis.However, these aluminum layers have a resistance mechanical limited and are extremely sensitive to creases.
Pour tenter de pallier ces inconvénients, il a été proposé d'intégrer dans la structure du pare-vapeur, lors de sa formation par enduction bitumineuse, simultanément avec la feuille d'aluminium, une armature de renforcement en non-tissé synthétique ou minéral.To try to overcome these drawbacks, it has been proposed to integrate into the structure of the vapor barrier, during its formation by bituminous coating, simultaneously with aluminum foil, a reinforcement reinforcement in synthetic or mineral fleece.
Bien qu'aboutissant à un certain renforcement de la structure du pare-vapeur résultant, cette dernière proposition ne contribue pas à l'augmentation de la résistance mécanique de la feuille d'aluminium au cours du procédé d'enduction bitumineux et la dissociation spatiale de cette dernière avec l'armature non-tissée limite le transfert de propriétés de cette dernière à ladite feuille d'aluminium et autorise un mouvement relatif entre ces deux composantes nuisible pour la bonne tenue du pare-vapeur.Although resulting in some strengthening of the structure of the resulting vapor barrier, this latter proposition does not help increasing the mechanical resistance of the aluminum foil to during the bituminous coating process and the spatial dissociation of this last with the nonwoven reinforcement limits the transfer of properties of this last to said aluminum foil and allows relative movement between these two components detrimental to the good performance of the vapor barrier.
En outre les nappes non-tissées peuvent constituer des cavités ou des amas fibreux susceptibles de retenir l'humidité et les nappes elles-mêmes peuvent s'imprégner par capillarité et autoriser ainsi la pénétration d'eau dans l'épaisseur du pare-vapeur.In addition, the nonwoven webs can constitute cavities. or fibrous lumps that can retain moisture and the webs themselves can permeate by capillarity and thus allow penetration of water in the thickness of the vapor barrier.
De plus le bitume doit être imprégné à force pour qu'il soit présent sur toute l'épaisseur de la nappe.In addition, the bitumen must be force-impregnated in order for it to be present over the entire thickness of the tablecloth.
La présente invention a notamment pour but de pallier les inconvénients précités.The present invention aims in particular to overcome the aforementioned drawbacks.
A cet effet, elle a pour objet une membrane pare-vapeur à base de bitume, caractérisée en ce qu'elle comporte une armature composite constituée par une feuille mince d'aluminium et par une grille en un matériau à haute résistance mécanique, assemblées entre elles par contrecollage, ladite armature composite étant revêtue sur ses deux faces de couches de matériaux à base de bitume éventuellement de compositions différentes.To this end, it relates to a vapor barrier membrane based bitumen, characterized in that it comprises a composite reinforcement consisting of a thin sheet of aluminum and a grid in one material with high mechanical resistance, joined together by laminating, said composite reinforcement being coated on its two faces with layers of bitumen-based materials, possibly of compositions different.
L'invention sera mieux comprise, grâce à la description ci-après,
qui se rapporte à des modes de réalisation préférés, donnés à titre
d'exemple non limitatif, et expliqués avec référence aux dessins
schématiques annexés, dans lesquels :
Comme le montre cette dernière, ladite membrane pare-vapeur
1 comporte une armature composite constituée par une feuille mince
continue d'aluminium 2 ou d'un alliage à base d'aluminium et par une grille
3 en un matériau à haute résistance mécanique, assemblées entre elles par
contrecollage, ladite armature composite 2, 3 étant revêtue sur ses deux
faces de couches de matériaux à base de bitume 4 et 5 éventuellement de
compositions différentes (une couche par face).As the latter shows, said vapor barrier membrane
1 comprises a composite reinforcement constituted by a thin sheet
La solidarisation intime de la grille 3 avec la feuille 2 permet de
renforcer cette dernière de manière contrôlée en lui conférant notamment
une résistance mécanique et une stabilité dimensionnelle suffisante dans le
sens de défilement lors de l'enduction bitumineuse.The intimate connection of the grid 3 with the
L'utilisation d'une grille 3, qui ne forme aucune cavité ou amas
fibreux, empêche toute rétention d'eau, ne permet aucune pénétration d'eau
par capillarité et ne nécessite aucune imprégnation à force du bitume (une
simple enduction suffit) pour recouvrir tous les fils ou filaments et être
appliquée intimement contre la feuille d'aluminium 2, en vue d'obtenir une
membrane pleine, sans cavité vide de bitume.The use of a grid 3, which does not form any cavity or cluster
fibrous, prevents water retention, does not allow water penetration
by capillarity and does not require any force impregnation of the bitumen (a
simple coating is enough) to cover all the threads or filaments and be
intimately applied against the
De plus, la solidarisation grille 3 / feuille 2 par collage adapté
évite tout perçage ou perforation de ladite feuille d'aluminium et permet de
conserver une couche d'aluminium continue et donc à ladite membrane
composite 1 d'être utilisée en tant que pare-vapeur.In addition, the grid 3 /
Conformément à un mode de réalisation préféré de l'invention,
l'armature composite est composée d'une grille de fils ou de filaments
continus synthétiques ou minéraux à résistance élevée, notamment d'une
grille de fils de verre 3, contrecollée sur une mince feuille d'aluminium 2
présentant, le cas échéant, une surface martelée favorisant l'adhérence des
couches de matériaux bitumineux et le pliage sans génération de lignes de
pli ou de lignes fragilisées.In accordance with a preferred embodiment of the invention,
the composite reinforcement is composed of a grid of wires or filaments
high-strength synthetic or mineral continuous materials, especially of
glass wire grid 3, laminated on a
Les fils ou filaments de la grille 3 pourront avantageusement être traités ou être formés pour être totalement dépourvus d'action par capillarité. La mise en oeuvre avantageuse d'une grille 3 de fils de verre confère à la membrane 1 une grande résistance mécanique et une absence d'allongement sous contrainte, au moins dans les directions d'orientation desdits fils.The son or filaments of the grid 3 may advantageously be treated or trained to be completely powerless by capillarity. The advantageous implementation of a grid 3 of glass strands gives membrane 1 a high mechanical resistance and an absence elongation under stress, at least in the directions of orientation of said sons.
Selon une caractéristique de l'invention, la couche supérieure du
revêtement bitumineux 4 est traitée pour présenter une surface 4' à
accrochage privilégié notamment pour la fixation d'une couche d'isolant 6
thermique et/ou acoustique traditionnel.According to a characteristic of the invention, the upper layer of the
Avantageusement la couche supérieure du revêtement
bitumineux 4 présente une surface 4' sablée ou ayant été soumise à un
traitement similaire, permettant un collage à chaud et/ou à froid de la
couche d'isolant 6.Advantageously the upper layer of the
Afin de permettre une fixation sans moyens mécaniques et sans percement de la membrane pare-vapeur 1, la couche de revêtement bitumineuse inférieure 5 consiste en un mélange bitumineux à propriétés collantes, préférentiellement autocollantes à froid sur de l'acier ou du béton.In order to allow fixing without mechanical means and without perforation of the vapor barrier membrane 1, the covering layer bituminous lower 5 consists of a bituminous mixture with properties sticky, preferably self-adhesive when cold on steel or concrete.
Du fait de son renforcement et de sa rigidification intimes, préalablement aux opérations d'enduction, il sera également possible de réduire l'épaisseur de la couche d'aluminium jusqu'à une valeur minimale nécessaire pour son enduction et pour former une barrière à la vapeur efficiente.Because of its intimate strengthening and stiffening, prior to coating operations, it will also be possible to reduce the thickness of the aluminum layer to a minimum value necessary for its coating and to form a vapor barrier efficient.
Ainsi, la feuille d'aluminium 2 pourra présenter une épaisseur
comprise entre 10 µm et 100 µm, préférentiellement entre 20 µm et 70 µm,
et la grille de verre 3 être constituée de fils de verre de titre compris entre 40
tex et 100 tex, préférentiellement entre 60 tex et 80 tex et arrangés dans un
réseau à deux composantes sensiblement orthogonales entre elles, les fils 3',
3" de chaque composante étant espacés d'un intervalle compris entre
1,5 mm et 10 mm, préférentiellement entre 3 mm et 4 mm.Thus, the
Le contrecollage feuille/grille pourra être réalisé au moyen d'une colle adaptée aux matériaux en présence et résistant aux températures d'enduction bitumineuse, par exemple une colle de type émulsion acrylique et/ou butadiène.The sheet / grid laminating can be done using an adhesive suitable for the materials present and resistant to temperatures bituminous coating, for example an acrylic emulsion type adhesive and / or butadiene.
La présente invention a également pour objet, comme le montre
notamment la figure 2 des dessins annexés, un complexe ou système isolant
et étanchéifiant pour toitures, notamment de bâtiments soumis à forte ou
très forte hygrométrie, caractérisé en ce qu'il est principalement constitué,
d'une part, par une membrane pare-vapeur 1 telle que décrite ci-dessus
reposant sur le support ou les éléments supports de toiture, d'autre part, par
une couche de matériau isolant 6 rapportée par collage à froid ou à chaud
sur ladite membrane pare-vapeur 1 et, enfin, par une ou plusieurs couche(s)
de revêtement extérieur d'étanchéité 7 rapportée(s) sur ladite couche
isolante 6, par collage à froid, à chaud ou par thermofusion.The subject of the present invention is also, as shown
in particular Figure 2 of the accompanying drawings, an insulating complex or system
and waterproofing for roofs, in particular of buildings subjected to high or
very high humidity, characterized in that it is mainly made up,
on the one hand, by a vapor barrier membrane 1 as described above
resting on the support or the roof support elements, on the other hand, by
a layer of insulating
Dans cette application, il peut être avantageusement prévu que
la membrane pare-vapeur 1 présente une sous-face autocollante à froid sur
l'acier et/ou le béton et est rapportée par collage sur les éléments support 8
constitutifs de la toiture, tels que les tôles d'acier nervurées, permettant de
supprimer toute fixation mécanique susceptible de traverser la membrane
pare-vapeur 1, la couche isolante 6 et/ou les bacs acier.In this application, it can advantageously be provided that
the vapor barrier membrane 1 has a cold self-adhesive underside on
steel and / or concrete and is attached by bonding to the
Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the mode of embodiment described and shown in the accompanying drawings. Modifications remain possible, especially from the point of view of the constitution of the various elements or by substitution of technical equivalents, without going out of the protection field of the invention.
