Description

L'invention concerne un dispositif de ventilation permettant l'isolation acoustique et installé sur un vitrage ou une paroi, comportant deux boîtiers disposés de part et d'autre dudit vitrage ou paroi. Ces dispositifs permettent d'une part de réaliser l'aération d'un local tout en constituant une isolation acoustique de ce local par rapport aux bruits extérieurs.The invention relates to a ventilation device for sound insulation and installed on a glazing or a wall, comprising two housings arranged on either side of said glazing or wall. On the one hand, these devices make it possible to ventilate a room while constituting an acoustic insulation of this room from outside noise.

Le problème de la ventilation de locaux présentant des ouvertures telles que des portes, des fenêtres ou analogues tout en réalisant une isolation acoustique a déjà été résolu de différentes manières. En particulier, on connaît des dispositifs de ventilation acoustique qui peuvent être disposés aussi bien sur les matériaux constituant les parois que sur les surfaces vitrées des ouvertures du local.The problem of ventilating rooms with openings such as doors, windows or the like while providing sound insulation has already been solved in different ways. In particular, acoustic ventilation devices are known which can be arranged both on the materials constituting the walls and on the glass surfaces of the openings in the room.

Ainsi, on connaît déjà des dispositifs de ventilation acoustique qui sont constitués d'un ou deux boîtiers réalisés à partir d'un profilé et venant en applique sur le matériau des parois en masquant de part et d'autre les bouches d'aération aménagées dans ladite paroi; ces dispositifs (p.e. FR-A 2 561 706) utilisent des matériaux absorbants au point de vue acoustique qui sont disposés, d'une part, à intérieur des boîtiers et, d'autre part, sur le support préparé à cet effet, de sorte qui'ils imposent à la circulation de l'air une trajectoire forcée non rectiligne. Ces dispositifs connus qui doivent respecter des normes et prescriptions en matière d'isolation phonique et acoustique et en matière de ventilation, mettent à profit les techniques issues de l'application de la physique des fluides et des sons.Acoustic ventilation devices are therefore already known which consist of one or two housings made from a profile and applied on the wall material by masking on both sides the air vents arranged in said wall; these devices (eg FR-A 2 561 706) use acoustically absorbent materials which are arranged, on the one hand, inside the housings and, on the other hand, on the support prepared for this purpose, so which they impose on the air circulation a non-rectilinear forced trajectory. These known devices which must comply with standards and prescriptions in terms of sound and acoustic insulation and in terms of ventilation, take advantage of the techniques resulting from the application of the physics of fluids and sounds.

Ces dispositifs de ventilation de type connu présentent des inconvénients à la fois pour les utilisateurs et pour les fabricants. Dans le cas de deux boîtiers différents disposés l'un à l'extérieur de la paroi, l'autre à l'intérieur, la fabrication nécessite de nombreux outillages, ce qui élève le coût de fabrication. Par ailleurs, les boîtiers doivent permettre d'obtenir le rejet d'eau à l'extérieur et ne doivent pas gêner le fonctionnement des ouvertures ainsi que des protections telles que volets, grilles ou analogues.These known type of ventilation devices have drawbacks for both users and manufacturers. In the case of two different housings arranged one outside the wall, the other inside, the manufacturing requires many tools, which increases the manufacturing cost. Furthermore, the boxes must allow the discharge of water to the outside and must not interfere with the operation of the openings as well as protections such as shutters, grilles or the like.

En ce qui concerne les utilisateurs, c'est-à-dire les constructeurs de bâtiments ou des intervenants dans des travaux de rénovation, ils doivent réaliser des travaux de façonnage pour préparer le support pour la réception d'appliques des dispositifs décrits ci-dessus, ce qui accroît le coût de la main- d'oeuvre.Regarding the users, that is to say, the builders of buildings or those involved in renovation works, they must carry out shaping work to prepare the support for the reception of wall lights from the devices described above. , which increases the cost of labor.

La présente invention se propose de réaliser un dispositif de ventilation à isolation acoustique, du type comportant deux boîtiers disposés de part et d'autre dudit vitrage ou paroi dont le coût de fabrication et d'installation est réduit, tout en réalisant une bonne isolation acoustique.The present invention proposes to produce a ventilation device with acoustic insulation, of the type comprising two housings arranged on either side of said glazing or wall whose manufacturing and installation cost is reduced, while achieving good acoustic insulation. .

Le dispositif de ventilation à isolation acoustique selon l'invention est notamment remarquable en ce qu'il est constitué de deux boîtiers identiques de forme allongée, qui comportent un trou de ventila dans une paroi hoizontale et qui sont disposés horizontalement, symétriquement par rapport à un axe horizontal médian, d'un support intermédiaire sur lequel chacun desdits boîtiers est fixé de manière amovible, qui est disposé à la place dudit vitrage ou paroi, qui présente approximativement les mêmes caractéristiques mécaniques que ce dernier et qui comporte deux trous de circulation disposés dans un plan horizontal et d'un manchon en matériau pelliculé lavable tel qu'une mousse présentant des propriétés isolantes acoustiques entourant l'espace intermédiaire entre les deux trous de circulation du support intermédiaire et réalisant en combinaison avec des matériaux isolants situés dans chacun des boîtiers un conduit reliant lesdits trous de ventilation et lesdits trous de circulation et conformés de sorte qu'ils ne comportent que des parois lisses et sans aspérités.The acoustically insulated ventilation device according to the invention is notably remarkable in that it consists of two identical elongated housings, which have a ventila hole in a horizontal wall and which are arranged horizontally, symmetrically with respect to a horizontal median axis, of an intermediate support on which each of said housings is detachably fixed, which is arranged in place of said glazing or wall, which has approximately the same mechanical characteristics as the latter and which has two circulation holes arranged in a horizontal plane and a sleeve of washable film-coated material such as a foam having acoustic insulating properties surrounding the intermediate space between the two circulation holes of the intermediate support and producing, in combination with insulating materials located in each of the housings, a duct connecting said ventilation holes and l Said circulation holes and shaped so that they have only smooth walls and without roughness.

Du fait que les deux boîtiers sont identiques, les coûts de fabrication sont fortement réduits ; par ailleurs, le conduit réalisant la ventilation présentant de bonnes qualités acoustiques, l'isolation acoustique est très satisfaisante. Le dispositif selon l'invention peut être utilisé aussi bien pour des travaux de réfection que pour des travaux neufs. Dans le cas d'une restauration, on peut utiliser le support intermédiaire ce qui nécessite un découpe de l'élément de paroi mais on peut également placer les boîtiers en applique sur la paroi existante sand aucune préparation supplémentaire. Dans le cas de travaux neufs, seul intervient le support intermédiaire. En effet, le constructeur va préparer une réservation dans la paroi ou poser une vitre dont les dimensions vont permettre la pose de ce support intermédiaire. Ceci permet d'une part de standardiser la production et d'autre part de protéger les boîtiers et les manchons qui restent dans leur emballage d'origine jusqu'à leur montage.Because the two boxes are identical, manufacturing costs are greatly reduced; moreover, the duct providing ventilation having good acoustic qualities, the sound insulation is very satisfactory. The device according to the invention can be used both for repair work and for new work. In the case of a restoration, one can use the intermediate support which requires a cutting of the wall element but one can also place the boxes on the existing wall without any additional preparation. In the case of new works, only the intermediate support intervenes. Indeed, the manufacturer will prepare a reservation in the wall or install a window whose dimensions will allow the installation of this intermediate support. This allows on the one hand to standardize the production and on the other hand to protect the cases and the sleeves which remain in their original packaging until their assembly.

Avantageusement, le manchon précité et le matériau isolant des boîtiers sont conformés de manière que ledit conduit ne comporte que des parois courbes et sans aspérités. De cette manière, la ventilation ne crée aucun bruit ; de plus, cela supprime la possibilité d'accumulation de poussières dans ledit conduit.Advantageously, the aforementioned sleeve and the insulating material of the housings are shaped so that said duct has only curved walls and without roughness. In this way, ventilation does not create any noise; moreover, this eliminates the possibility of accumulation of dust in said duct.

Selon une autre caractéristique de l'invention, le manchon est réalisé en une mousse pelliculée lavable. Ceci permet de réaliser un nettoyage du dispositif de ventilation, le conduit recouvrant après lavage ses qualités d'isolation acoustique.According to another characteristic of the invention, the sleeve is made of a washable film-coated foam. This makes it possible to clean the ventilation device, the duct covering after washing its qualities of acoustic insulation.

Le support intermédiaire peut être muni au moins partiellement d'une parclose ; en particulier, dans le cas où le dispositif selon l'invention est monté sur un vitrage, la parclose remplacera la feuillure dans les endroits où le support intermédiaire n'est pas logé dans une telle feuillure.The intermediate support can be provided at least partially with a glazing bead; in particular, in the case where the device according to the invention is mounted on a glazing, the glazing bead will replace the rebate in the places where the intermediate support is not housed in such a rebate.

Selon un mode de réalisation de l'invention, chaque boîtier est constitué par un profilé horizontal muni d'un paroi de fermeture à chacune de ses extrémités et le matériau isolant dudit boîtier est constitué de deux pièces identiques en forme d'auges qui sont disposées symétriquement par rapport à un axe horizontal médian, les faces libres desdites pièces en forme d'auges se faisant face, et qui comportent sur un de leurs côtés une ouverture en regard du trou de ventilation précité. Ce mode de réalisation permet également de simplifier tant la fabrication que la mise en place du dispositif de ventilation selon l'invention.According to one embodiment of the invention, each housing is constituted by a horizontal profile provided with a closure wall at each of its ends and the insulating material of said housing consists of two identical parts in the form of troughs which are arranged symmetrically with respect to a median horizontal axis, the free faces of said trough-shaped parts facing each other, and which have on one of their sides an opening opposite the aforementioned ventilation hole. This embodiment also makes it possible to simplify both the manufacturing as the establishment of the ventilation device according to the invention.

D'autres caractéristiques et avantages dee l'invention ressortiront de la description qui suit ainsi que des dessins ci-annexés sur lesquels :

  • la figure 1 est une vue en coupe verticale d'un dispositif de ventilation selon l'invention;
  • la figure 2 est une vue en coupe horizontale selon la ligne 11-11 de la figure 1, et
  • la figure 3 est une vue en perspective éclatée du dispositif de ventilation selon l'invention.
Other characteristics and advantages of the invention will emerge from the description which follows as well as from the appended drawings in which:
  • Figure 1 is a vertical sectional view of a ventilation device according to the invention;
  • FIG. 2 is a view in horizontal section on line 11-11 of FIG. 1, and
  • Figure 3 is an exploded perspective view of the ventilation device according to the invention.

Comme on peut le voir en particulier sur la figure 1, le dispositif de ventilation selon l'invention est constitué de deux boîtiers, un boîtier inté rieur 1 et un boîtier extérieur 2 qui sont identiques et qui sont placés de part et d'autre d'une paroi ou d'un vitrage 3 ; ces deux boîtiers comportent un trou de ventilation 4 respectivement 5, qui sont aménagés dans une paroi 6 respectivement 7 sensiblement horizontale. Les deux boîtiers 1 et 2 sont disposés l'un par rapport à l'autre de manière inversée à 1800 autour d'un axe horizontal 8 de telle sorte que le trou de ventilation intérieur 6 débouche vers le haut et que le trou de ventilation extérieur 7 débouche vers le bas.As can be seen in particular in FIG. 1, the ventilation device according to the invention consists of two housings, an interior housing 1 and an exterior housing 2 which are identical and which are placed on either side of the housing. 'a wall or glazing 3; these two housings have a ventilation hole 4 respectively 5, which are arranged in a wall 6 respectively 7 substantially horizontal. The two housings 1 and 2 are arranged with respect to each other in an inverted manner at 180 0 around a horizontal axis 8 so that the internal ventilation hole 6 opens upwards and the ventilation hole exterior 7 opens down.

Les deux boîtiers 1 et 2 sont fixés chacun sur un support intermédiaire 9 qui est placé dans une ouverture aménagée dans la paroi ou le vitrage 3. Dans le cas où le dispositif de ventilation selon l'invention est placé sur un vitrage, on peut avantageusement découper une bande supérieure dans le vitrage de telle manière que le support intermédiaire 9 soit fixé par les feuillures de la fenêtre ; une parclose (non représentée) peut avantageusement être disposée sur ledit support intermédiaire de manière à consolider sa fixation sur le vitrage. Cette parclose peut être placée sur la face du support intermédiaire 9 qui n'est pas engagée dans la feuillure. Le support intermédiaire remplace donc la paroi ou vitrage sur lequel est mis en place le dispositif de ventilation selon l'invention ; il est avantageux de réaliser ce support intermédiaire dans une matière qui présente les mêmes caractéristiques mécaniques que la paroi ou le vitrage considéré de manière à ne pas diminuer la résistance mécanique de l'ensemble de la paroi ou du vitrage.The two boxes 1 and 2 are each fixed to an intermediate support 9 which is placed in an opening in the wall or the glazing 3. In the case where the ventilation device according to the invention is placed on a glazing, it is advantageously possible cut an upper strip in the glazing so that the intermediate support 9 is fixed by the rebates of the window; a glazing bead (not shown) can advantageously be arranged on said intermediate support so as to consolidate its fixing to the glazing. This glazing bead can be placed on the face of the intermediate support 9 which is not engaged in the rebate. The intermediate support therefore replaces the wall or glazing on which the ventilation device according to the invention is installed; it is advantageous to produce this intermediate support in a material which has the same mechanical characteristics as the wall or the glazing considered so as not to reduce the mechanical resistance of the entire wall or glazing.

Au moins un des trous de ventilation 4 ou 5 est muni d'un dispositif de filtrage tel qu'une grille 11 qui peut être disposée à l'extérieur ou à l'inté rieur du boîtier 2. Ce dispositif de filtrage évite l'introduction de particules de toutes sortes quand il est disposé à l'extérieur et quand il est disposé à l'intérieur il capte des microparticules et fait ainsi office de purificateur.At least one of the ventilation holes 4 or 5 is provided with a filtering device such as a grid 11 which can be arranged outside or inside the housing 2. This filtering device avoids the introduction particles of all kinds when it is placed outside and when it is placed inside it captures microparticles and thus acts as a purifier.

Conformément à l'invention, on prévoit un manchon 12 qui est réalisé en une matière qui présente des propriétés isolantes du point de vue acoustique; ce manchon est conformé de manière à réaliser, en combinaison avec des matériaux isolants situés dans chacun des boîtiers, un conduit reliant les deux trous de ventilation 4 et 5 ; à cet effet, on prévoit dans le support interméiaire 9 deux trous de circulation 13 et 14 qui sont disposés tous les deux dans un plan horizontal à chacune des extrémités dudit support intermédiaire 9. Comme on peut le voir en particulier sur la figure 2, le manchon 12 entoure la partie 15 du support intermédiaire 9 qui est comprise entre les deux trous de circulation 13 et 14. De préférence, le manchon 12 est conformé de telle manière que le conduit 16 reliant les trous de ventilation et les trous de circulation présentent des surfaces lisses sans aspérités ni recoins de manière à éviter toute accumulation de poussière dans ce conduit.According to the invention, a sleeve 12 is provided which is made of a material which has insulating properties from an acoustic point of view; this sleeve is shaped so as to produce, in combination with insulating materials located in each of the housings, a duct connecting the two ventilation holes 4 and 5; for this purpose, there are provided in the intermediate support 9 two circulation holes 13 and 14 which are both arranged in a horizontal plane at each end of said intermediate support 9. As can be seen in particular in FIG. 2, the sleeve 12 surrounds part 15 of the intermediate support 9 which is between the two circulation holes 13 and 14. Preferably, the sleeve 12 is shaped so that the duct 16 connecting the ventilation holes and the circulation holes has smooth surfaces without roughness or nooks so as to avoid any accumulation of dust in this duct.

La matière isolante utilisée pour réaliser le manchon 12 est de préférence une mousse pelliculée lavable ; cela permet de procéder au nettoyage du manchon, le cas échéant ; en effet, les qualités d'isolation acoustique d'une telle mousse ne sont pas modifiées par cette opération de lavage.The insulating material used to make the sleeve 12 is preferably a washable film-coated foam; this allows the sleeve to be cleaned, if necessary; in fact, the sound insulation qualities of such foam are not modified by this washing operation.

La figure 3 est une vue en perspective éclatée d'un mode de réalisation de l'invention. On voit que les boîtiers sont constitués par une section de profilé 17 qui est fermée à chacune des ses extrémités par une paroi de fermeture 18. Les trous de ventilation sont de forme oblongue et disposés au centre du profilé 17.Figure 3 is an exploded perspective view of an embodiment of the invention. It can be seen that the housings are constituted by a section of profile 17 which is closed at each of its ends by a closing wall 18. The ventilation holes are of oblong shape and arranged in the center of profile 17.

Sur la partie gauche de la figure, une moitié du machon a été représentée démontée. De part et d'autre de la pièce intermédiaire 9, le "matériau absorbant du conduit est constitué d'une pièce 19 en forme d'auge dont le fond 21 est disposé du côté du fond du profilé 17, la face libre 22 de ladite pièce en forme d'auge 19 étant dirigée vers le support intermédiaire 9 avec lequel elle vient en contact lorsque l'ensemble du dispositif est monté. La pièce 19 comporte une couverture 23 disposée en regard du trou de ventilation 4. L'invention nécessite une plaque 24 qui vient se mettre au fond du profilé 17 entre ce dernier et la pièce 19 en forme d'auge.On the left side of the figure, half of the machon has been shown disassembled. On either side of the intermediate piece 9, the "absorbent material of the duct consists of a piece 19 in the shape of a trough, the bottom 21 of which is disposed on the side of the bottom of the profile 17, the free face 22 of said trough-shaped part 19 being directed towards the intermediate support 9 with which it comes into contact when the entire device is mounted .. The part 19 comprises a cover 23 disposed opposite the ventilation hole 4. The invention requires a plate 24 which is placed at the bottom of the profile 17 between the latter and the part 19 in the form of a trough.

Comme pour les boîtiers, la pièce 19 en forme d'auge disposée à l'extérieur et qui se trouve dans le profilé de la partie droite de la figure est disposée avec inversion à 180° de manière que son ouverture 23 soit disposée en regard du trou de ventilation 5 qui n'est pas visible sur la figure.As for the housings, the part 19 in the shape of a trough disposed outside and which is in the profile of the right part of the figure is arranged with 180 ° inversion so that its opening 23 is arranged facing the ventilation hole 5 which is not visible in the figure.

Avantageusement, l'ensemble du dispositif de ventilation selon l'invention est démontable, les boîtiers 1 et 2 étant fixés de manière amovible sur le support intermédiaire 9. Cette fixation peut se faire par encliquetage du boîtier sur le support intermédiaire ; on peut également prévoir une fixation par accrochage d'une arête du boîtier sur le support intermédiaire, la deuxième arête opposée étant bloquée par exemple au moyen d'une vis. Enfin, on peut prévoir également une fixation par vissage direct du boîtier sur la pièce intermédiaire et on prévoit dans ce cas des trous de passage de vis dans le boîtier à chacune de ses extrémités.Advantageously, the assembly of the ventilation device according to the invention is removable, the boxes 1 and 2 being removably fixed on the intermediate support 9. This fixing can be done by snap-fastening of the box on the intermediate support; one can also provide a fixing by hooking an edge of the housing on the intermediate support, the second opposite edge being blocked for example by means of a screw. Finally, provision can also be made for direct screwing of the housing to the intermediate piece and in this case provision is made for screw passage holes in the housing at each of its ends.

Avantageusement, le boîtier est muni de joints qui permettent d'obtenir une bonne étanchéité lorsqu'il est fixé sur la pièce intermédiaire.Advantageously, the housing is provided with seals which make it possible to obtain a good seal when it is fixed to the intermediate piece.

On voit que l'invention permet de simplifier notablement le coût de fabrication de tels dispositifs de ventilation puisque le dispositif selon l'invention est seulement constitué de deux boîtiers identiques, de deux éléments de manchon identiques et d'un support intermédiaire. L'ensemble étant facilement démontable, on peut procéder à son entretien, en particulier en procédant au lavage du manchon. Lors du démontage, la pièce intermédiaire reste en place sur la paroi ou le vitrage et cette opération de démontage est très rapide puisqu'il suiffit d dégager le boîtier et d'en extraire l'élément de manchon.It can be seen that the invention makes it possible to considerably simplify the manufacturing cost of such ventilation devices since the device according to the invention only consists of two identical housings, two identical sleeve elements and an intermediate support. The whole being easily removable, it can be maintained, in particular by washing the sleeve. During disassembly, the intermediate piece remains in place on the wall or the glazing and this disassembly operation is very rapid since it suffices to disengage the housing and extract the sleeve element therefrom.

Comme on peut le voir sur la figure 1, du fait de la disposition alternée des deux trous de ventilation intérieur 4 et extérieur 5, ce dernier est disposé dans la paroi inférieure du boîtier extérieur 2. Pour éviter le ruissellement d'eau et la pénétration d'eau à l'intérieur du boîtier par le trou de ventilation extérieur 5, l'arête longitudinale 20 proche du trou de ventilation déborde du plan du boîtier comme on peut le voir en particulier sur la figure 1. Par ailleurs, du fait que le trou de ventilation intérieur 4 qui est dirigé vers le haut, l'air frais qui peut pénétrer par le dispositif n'est pas envoyé directement sur les personnes se trouvant dans le local comme cela peut être le cas avec des dispositifs de ventilation dans lesquels les trous de ventilation sont disposés verticalement.As can be seen in Figure 1, due to the alternating arrangement of the two interior 4 and exterior 5 ventilation holes, the latter is disposed in the bottom wall of the exterior housing 2. To avoid water runoff and penetration of water inside the housing through the external ventilation hole 5, the longitudinal edge 20 close to the ventilation hole projects beyond the plane of the housing as can be seen in particular in FIG. 1. Furthermore, because the internal ventilation hole 4 which is directed upwards, the fresh air which can penetrate through the device is not sent directly to the people in the room as may be the case with ventilation devices in which the ventilation holes are arranged vertically.

Comme on peut le voir en particulier sur la figure 3, il est avantageux que le support intercalaire 9 déborde au-delà du périmètre de la surface de contact du boîtier. Cet espace disponsible permet la pose du support intercalaire sur des feuillures prévues pour recevoir initialement un vitrage et pour recevoir par ailleurs éventuellement une parclose comme indiqué ci-dessus ; cette parclose fixée sur les montants de l'ouvrage assure alors le contact étanche et solide du support intercalaire avec le vitrage ou la paroi. On peut également concevoir, selon une variante de réalisation, un support intercalaire qui présente sur l'un de ses bords une parclose intégrée à sa masse, apte à recevoir le bord du vitrage, ainsi que des moyens d'étanchéité.As can be seen in particular in FIG. 3, it is advantageous for the intermediate support 9 to project beyond the perimeter of the contact surface of the housing. This available space allows the installation of the intermediate support on rebates provided to initially receive glazing and to also optionally receive a glazing bead as indicated above; this glazing bead fixed on the uprights of the structure then ensures tight and solid contact of the intermediate support with the glazing or the wall. One can also design, according to an alternative embodiment, an intermediate support which has on one of its edges a glazing bead integrated in its mass, capable of receiving the edge of the glazing, as well as sealing means.

Selon l'invention on peut également prévoir d'installer des limiteurs de débit connus sous le nom d'entrées d'air autoréglables (débit d'environ 100 m3/h) à l'intérieur du boîtier extérieur 2. Cela présente l'avantage d'équilibrer les débits dans un local qui est ventilé de manière mécanique lorsque cela est nécessaire.According to the invention, provision can also be made to install flow limiters known under the name of self-adjusting air inlets (flow rate of approximately 100 m 3 / h) inside the outer casing 2. This has the advantage to balance the flows in a room which is mechanically ventilated when necessary.

Le dispositif selon l'invention peut être utilisé en premier montage dans le cas d'une construction neuve ou en remplacement à la place d'un dispositif existant ; dans ce cas il se substitue aux anciens dispositifs en respectant l'état du support.The device according to the invention can be used as a first assembly in the case of a new construction or as a replacement in place of an existing device; in this case it replaces the old devices while respecting the state of the support.

Dans le cas où l'on désire éviter des travaux de façonnage sur des parois ou des montants de fenêtres, qui sont de plus en plus réalisés avec des matériaux tels que des profilés en aluminium ou autres matériaux creux interdisant toute intervention dans leur masse, l'invention permet de placer un dispositif de ventilation en remplacement d'une partie supérieure d'un vitrage par exemple. Dans ce cas des opérations de mise en place sont réduites au maximum.If it is desired to avoid shaping work on walls or window jambs, which are increasingly made with materials such as aluminum profiles or other hollow materials preventing any intervention in their mass, l he invention allows to place a ventilation device to replace an upper part of a glazing for example. In this case, set-up operations are reduced to a minimum.

L'invention permet également de réaliser un conduit de ventilation qui présente l'état intérieur d'un boyau lisse, ce qui permet de respecter les normes et prescriptions en matière d'isolation acous tique.The invention also makes it possible to produce a ventilation duct which has the internal condition of a smooth hose, which makes it possible to comply with the standards and prescriptions in terms of acoustic insulation.

L'utilisation d'une mousse à surface pelliculée permet d'obtenir un dispositif qui peut être lavé et nettoyé, ce qui en augmente la durée de vie efficace.The use of a foam with a film-coated surface makes it possible to obtain a device which can be washed and cleaned, which increases its effective life.
