Abstract

The carrier material consisting of glass fibres and/or mineral fibres is sealed with respect to water vapour, is designed such that it has at least three layers and is connected to the insulating material to form an insulating element for sound and/or heat insulation. One of the two outer layers (4, 6) of the carrier material (2) has, with low production complexity for high fireproofing requirements, through-passages (5) as points of adhesion between the insulating material (3) and a layer (7) which fixes the perforated outer layer (6) on a material layer (4) with continuous surface, likewise has a continuous surface and consists of a sealable composition.

Description

Matériau isolant à plusieurs couches.Insulating material with several layers.

L'invention est relative à un matériau-support destiné à supporter un matériau d'isolation constitué de fibres ou laine de verre et/#u de fibres minérales, lequel matériau-support comporte au minimum trois couches, est étanche à la vapeur d'eau et est lié au matériau d'isolation de façon à former un élément isolant destiné à l'isolation acoustique et/ou thermique. The invention relates to a support material intended to support an insulation material consisting of fibers or glass wool and / # u of mineral fibers, which support material comprises at least three layers, is vapor tight. water and is linked to the insulation material so as to form an insulating element intended for acoustic and / or thermal insulation.

De tels éléments isolants sont utilisés par exemple pour le revêtement de toits, de murs ou de parois et de plafonds ainsi que pour le revêtement de tuyauteries de chauffage ou de gaines de ventilation. Such insulating elements are used for example for coating roofs, walls or walls and ceilings as well as for coating heating pipes or ventilation ducts.

Ils peuvent comporter une base constituée d'un matériausupport étanche à la vapeur d'eau et formé d'au moins trois couches, lequel est lié au matériau d'isolation en fibres ou laine de verre et/ou en fibres minérales.They may include a base made of a support material that is impervious to water vapor and formed of at least three layers, which is linked to the insulation material made of glass fibers or wool and / or mineral fibers.

Parmi les trois couches du matériau-support, les couches extérieures sont constituées de feuilles ou de bandes métalliques minces, de papiers, traités ou non chimiquement, ou bien encore de feuilles minces en matière plastique. Le choix des matières utilisées dépend en règle générale du but et du lieu de leur mise en oeuvre. Elles devraient cependant en principe présenter des qualités telles qu'elles puissent satisfaire aux exigences imposées dans chaque cas pour ce qui concerne la résistance mécanique ainsi que leur résistance aux effets de la température, du feu et à l'attaque par des substances chimiques Elles servent en outre à protéger l'élément isolant au cours du transport, à faciliter son montage, à fournir une surface agréable à voir et à la protection contre les incendies.Mais plus particulière- ment les surfaces extérieures ont à assumer la fonction d'un barrage dit barrage contre le passage de la vapeur d'eau, c'est-à-dire qu'elles doivent séparer parfaitement l'un de l'autre deux milieux climatiques, la plupart du temps différents, situés de chaque côté de l'élément isolant.Among the three layers of the support material, the outer layers consist of thin metal sheets or strips, of paper, whether or not chemically treated, or else of thin plastic sheets. The choice of materials used generally depends on the purpose and location of their use. In principle, however, they should have qualities such that they can meet the requirements imposed in each case with regard to mechanical strength as well as their resistance to the effects of temperature, fire and attack by chemical substances. moreover to protect the insulating element during transport, to facilitate its assembly, to provide a pleasant surface to see and to protection against fires. But more particularly the external surfaces have to assume the function of a barrier said barrier against the passage of water vapor, that is to say that they must perfectly separate from each other two climatic environments, most of the time different, located on each side of the element insulating.

Pour fabriquer un élément isolant, on commence par lier entre elles, par exemple par collage, deux couches de matière constituées par exemple d'une feuille d'aluminium, dont la surface est continue. Ensuite on fixe sur une des couches extérieures le matériau d'isolation se composant de fibres de verre et/ou de substances minérales, par exemple de laine minérale. To manufacture an insulating element, one begins by bonding together, for example by gluing, two layers of material consisting for example of aluminum foil, the surface of which is continuous. Next, the insulation material consisting of glass fibers and / or mineral substances, for example mineral wool, is fixed to one of the outer layers.

Dans ce but, dans une première phase de traitement, les deux couches de matière présentant une surface continue sont liées entre elles par une matière adhésive appropriée ou par une substance capable d'assurer le cachetage dite cire à cacheter" ; puis dans une deuxième phase de traitement le matériau-support à plusieurs couches ainsi constitué est revêtu d'un enduit qui assure une bonne adhérence du matériau d'isolation sur le matériau-support.  For this purpose, in a first treatment phase, the two layers of material having a continuous surface are bonded together by an appropriate adhesive material or by a substance capable of ensuring the sealing known as sealing wax "; then in a second phase The multi-layer support material thus formed is coated with a coating which ensures good adhesion of the insulation material to the support material.

Il est à cet égard connu de commencer par enduire, indépendamment du matériau d'isolation, le matériau-support d'une couche susceptible d'assurer l'adhésion ou le cachetage. On choisit en général pour cela le procédé d'application d'une telle masse, qui sera appelée dans la suite "cire à cacheter", par laminage ou par engagement de cette "cire" dans une filière à large fente. Le matériau-support préalablement traité de cette manière est ensuite, dans une opération ultérieure, chauffé afin d'assurer sa liaison avec le matériau d'isolation en utilisant un moyen auxiliaire, par exemple un cylindre de chauffage, de sorte que la masse de cire à cacheter se plastifie, grâce à quoi se produit une liaison avec le matériau d'isolation et, après refroidissement, se trouve réalisée l'adhérence du matériau d'isolation sur le matériau-support.Il est en outre connu d'enduire, peu avant que se trouve réalisée la liaison du matériau-support avec le matériau d'isolation, ledit matériau-support, dont l'alimentation se fait la plupart du temps -sous forme de bande continue, de substances adhésives dissoutes ou en solution aqueuse, comme des dispersions, des émulsions ou des verres solubles. Les bandes ainsi enduites sont, immédiatement après, mises en contact avec le matériau d'isolation à la suite de quoi elles sont séchées. In this regard, it is known to start by coating, independently of the insulation material, the support material with a layer capable of ensuring adhesion or sealing. In general, the method of applying such a mass is chosen for this, which will hereinafter be called "sealing wax", by rolling or by engagement of this "wax" in a wide slit die. The support material previously treated in this way is then, in a subsequent operation, heated in order to ensure its connection with the insulation material using an auxiliary means, for example a heating cylinder, so that the mass of wax to seal becomes plasticized, whereby a bond with the insulation material occurs and, after cooling, the adhesion of the insulation material to the support material is achieved. It is also known to coat, little before the bonding of the support material with the insulation material is carried out, said support material, the supply of which is most of the time - in the form of a continuous strip, of dissolved adhesive substances or in aqueous solution, such as dispersions, emulsions or soluble glasses. The strips thus coated are immediately brought into contact with the insulation material, after which they are dried.

Quel que soit le procédé utilisé pour effectuer le dépôt ou l'enduction, il en résulte cependant des dépenses importantes de matériel et de traitement. En particulier lorsque pour la fixation du matériau d'isolation on utilise des substances adhésives, leur application et leur séchage après fixation du matériau d'isolation sur le matériau-support exige des dispositifs de haute valeur technique et un contrôle précis. Whatever the process used for depositing or coating, however, this results in significant material and processing expenses. In particular when adhesive substances are used for fixing the insulation material, their application and drying after fixing the insulation material on the support material requires devices of high technical value and precise control.

Il s'y ajoute encore les dépenses d'énergie entralanées par le séchage.Added to this is the energy expenditure incurred during drying.

Outre les inconvénients tenant à la technique de fabrication, un autre inconvénient sérieux des éléments isolants connus tient à ce qu'ils ne satisfont pas aux prescriptions exigées pour obtenir une haute qualification pour ce qui concerne la protection contre les incendies. Il subsiste notamment le danger qu'une flamme puisse, sans rencontrer d'obstacle, se propager le long de la couche de "cire à cacheter entre le matériau d'isolation et la couche de matériau-support voisine du fait qu'aucun barrage ne s'y oppose à cet endroit. In addition to the drawbacks relating to the manufacturing technique, another serious drawback of the known insulating elements is that they do not meet the requirements required to obtain a high qualification with regard to fire protection. There remains in particular the danger that a flame may, without encountering an obstacle, propagate along the layer of "sealing wax between the insulation material and the layer of neighboring support material because no dam opposes it there.

Il est en outre possible aussi, dans le cas où on utilise un matériau-support à trois couches de déposer sur l'une des couches extérieures un revêtement qui d'une part s'oppose à la propagation des flammes ou tout au moins gêne celle-ci et d'autre part permet d'obtenir une adhérence impeccable du matériau d'isolation sur le matériau-support. Mais un tel revêtement est d'un coût disproportionné et en conséquence entratne des dépenses supplémentaires, demande beaucoup de temps et est lié à la mise en oeuvre de machines spéciales. It is furthermore also possible, in the case where a three-layer support material is used, to deposit on one of the outer layers a coating which on the one hand prevents the propagation of flames or at least hinders that -this and on the other hand allows to obtain an impeccable adhesion of the insulation material on the support material. However, such a coating is disproportionately expensive and consequently involves additional expenditure, is very time-consuming and is linked to the use of special machines.

Le but de l'invention est en conséquence de fournir un matériau-support pour un élément isolant ser vant à l'isolation acoustique et/ou thermique, qui, du point de vue de la technique de fabrication soit considérablement moins exigeant en coût et en moyens et qui garantisse une liaison avec le matériau d'isolation qui satisfasse aussi aux sévères exigences imposées par la protection contre les incendies. The object of the invention is therefore to provide a support material for an insulating element serving acoustic and / or thermal insulation, which, from the point of view of the manufacturing technique is considerably less demanding in cost and in means and which guarantees a bond with the insulation material which also satisfies the severe requirements imposed by fire protection.

Ce problème est résolu selon l'invention du fait que l'une des deux couches ex-térieuresdu matériau-support comporte des trous constituant des emplacements d'adhérence entre d'une part le matériau d'isolation et d'autre part une couche, constituée par une substance capable d'assurer le cachetage, qui fixe la couche extérieure percée de trous sur une couche du matériau-support présentant une surface continue, ladite couche de cachetage présentant elle-meme une surface continue. This problem is solved according to the invention because one of the two outer layers of the support material has holes constituting adhesion locations between on the one hand the insulation material and on the other hand a layer, constituted by a substance capable of ensuring sealing, which fixes the outer layer pierced with holes on a layer of the support material having a continuous surface, said sealing layer itself having a continuous surface.

L'idée fondamentale qui constitue l'essentiel des dispositions conformes à l'invention est donc l'utilisation, comme moyen de fixation du matériau d'isolation sur le matériau-support, d'une masse de "cire à cacheter" qui fixe la couche du matériau-support entrant en contact avec le matériau d'isolation sur une autre couche du matériau-support présentant une surface continue et qui est également étendue suivant une surface continue. Il est donc possible de renoncer à déposer une nouvelle couche du matériau-support destinée à fixer le matériau d'isolation. De la sorte se trouvent supprimées d'autres opérations et les machines correspondantes. On fait ainsi une économie de personnel et de matières, comme par exemple de substances adhésives ou destinées à assurer le cachetage, de sorte que finalement le coût total de fabrication des éléments isolants se trouve lui aussi considérablement réduit. The basic idea which constitutes the essential of the arrangements in accordance with the invention is therefore the use, as a means of fixing the insulation material to the support material, of a mass of "sealing wax" which fixes the layer of the support material coming into contact with the insulation material on another layer of the support material having a continuous surface and which is also extended along a continuous surface. It is therefore possible to dispense with depositing a new layer of the support material intended to fix the insulation material. This eliminates other operations and the corresponding machines. This saves personnel and materials, such as adhesive substances or intended to ensure sealing, so that ultimately the total cost of manufacturing the insulating elements is also considerably reduced.

Grâce à l'utilisation d'un matériau-support constitué d'au moins trois couches (deux couches extérieures, une couche de liaison) dont deux présentent une surface continue et possèdent par conséquent une étanchéité à la vapeur d'eau suffisante, les qualités que l'on exige pour un matériau-support se trouvent, d'une manière particulièrement appropriée, réparties entre les différentes couches. Thanks to the use of a support material consisting of at least three layers (two outer layers, one bonding layer), two of which have a continuous surface and therefore have a sufficient vapor-tightness, the qualities which are required for a support material are, in a particularly suitable manner, distributed between the different layers.

La liaison entre le matériau-support et le matériau d'isolation est obtenue du fait que, lorsque l'on chauffe la "cire à cacheter", les trous sont seuls à entrer en contact avec le matériau d'isolation de sorte qu'il n'existe que des emplacements d'adhérence localisés sur des zones. Il est dans ce cas d'une importance particulière que la constitution, la dimension et la répartition de ces emplacements d'adhérence dans le plan de la couche du matériau-support qui est voisine du matériau d'isolation soient choisies de telle sorte que, compte tenu du lieu de mise en oeuvre de l'élément isolant complet, de la façon, qui dépend des conditions- locales, dont ont été façonnées les matières constituant le matériau-support ainsi que des caractéristiques de la substance capable d'assurer le cachetage - une propagation des flammes d'un emplacement d'adhérence à un autre emplacement d'adhérence soit totalement arrêtée dans le cas où un incendie éclaterait éventuellement au lieu de mise en oeuvre. Les zones des surfaces ne comportant pas de trous, lorsqu'elles sont constituées d'une couche non combustible, comme par exemple par une feuille mince métallique, constituent donc dans une certaine mesure des barrages qui interdisent en toute sécurité aux flammes de se propager dans le plan de l'élément isolant. Un élément isolant muni d'un matériau-support selon l'invention satisfait donc aussi aux exigences très sévères imposées par la prévention des incendies. The connection between the support material and the insulation material is obtained by the fact that, when the "sealing wax" is heated, the holes are the only ones to come into contact with the insulation material so that it there are only grip locations located on zones. It is in this case of particular importance that the constitution, the dimension and the distribution of these locations of adhesion in the plane of the layer of the support material which is adjacent to the insulation material are chosen so that, taking into account the place of implementation of the complete insulating element, in the way which depends on the local conditions, from which the materials constituting the support material have been shaped as well as the characteristics of the substance capable of ensuring sealing - propagation of the flames from one adhesion location to another adhesion location is completely stopped in the event that a fire eventually breaks out at the place of implementation. The areas of the surfaces without holes, when they are made of a non-combustible layer, such as for example by a thin metallic sheet, therefore constitute to a certain extent barriers which safely prevent the flames from propagating in the plane of the insulating element. An insulating element provided with a support material according to the invention therefore also satisfies the very severe requirements imposed by fire prevention.

La couche à surface continue capable d'assurer le cachetage, interposée entre la couche du matériausupport percée de trous et la couche du matériau support présentant une surface continue qui la limite, doit, dans les domaines de température convenant au cachetage, se prêter à une bonne liaison avec le matériau d'isolation et de plus, après refroidissement, garantir une liaison impeccable des différentes couches du matériausupport. Il est par conséquent avantageux que la substance destinée à assurer le cachetage soit un polyéthylène à haute ou basse pression. On peut également penser aux chlorures de polyvinyle ainsi qu'aux chlorures de polyvinylidène.On peut en outre utilise des p-olyest##s, ,d#s polyamides des polypropylèneS ou bien encore des mélanges ou des copolymères de ces substances ainsi que des résines synthétiques et des ionomères. Les couches du matériau-support maintenues assemblées par la "cire à cacheter" se composent de substances qui satisfont aux exigences qui s'imposent au lieu d'emploi envisagé du point de vue de la résistance mécanique et de la stabilité aux variations de température, à l'action du feu et des substances chimiques. The continuous surface layer capable of sealing, interposed between the layer of the support material pierced with holes and the layer of the support material having a continuous surface which limits it, must, in the temperature ranges suitable for sealing, be suitable for good bond with the insulation material and further, after cooling, guarantee an impeccable bond of the different layers of the support material. It is therefore advantageous if the substance intended to ensure sealing is a polyethylene at high or low pressure. We can also think of polyvinyl chlorides as well as polyvinylidene chlorides. We can also use p-olyest ## s,, polyamides of polypropyleneS or even mixtures or copolymers of these substances as well as synthetic resins and ionomers. The layers of the support material held together by the "sealing wax" are composed of substances which meet the requirements which are imposed on the intended place of use from the point of view of mechanical resistance and stability to temperature variations, to the action of fire and chemicals.

Il peut s'agir de feuilles ou de bandes métalliques minces, de papiers traités ou non chimiquement ainsi que de feuilles en matières synthétiques et de fibres de verre sous forme de laine ou de tissu. Ces matières garantissent non seulement une mise en oeuvre sans problèmes du matériau-support au moment de la liaison avec le matériau d'isolation mais elles sont de plus facilement pliables et flexibles et susceptibles de supporter des contraintes élevées. Elles présentent de plus une résistance élevée à la déchirure et à la propagation des déchirures qui s'amorceraient ainsi qu'en particulier la propriété d'assurer un bon barrage contre la vapeur d'eau.They may be thin metal sheets or strips, paper treated or not chemically treated as well as sheets made of synthetic materials and glass fibers in the form of wool or fabric. These materials not only guarantee trouble-free implementation of the support material at the time of bonding with the insulation material, but they are moreover easily foldable and flexible and capable of withstanding high stresses. They also have a high resistance to tearing and the propagation of tears which would initiate, and in particular the property of ensuring a good barrier against water vapor.

Bien qu'il suffise en général que le matériausupport se compose uniquement de la couche percée de trous et d'une autre couche de surface continue liée à la précédente par la masse de "cire à cacheter", il peut être avantageux dans certains cas d'intercaler entre ces couches du matériau-support, afin d'augmenter la résistance mécanique, un tissu, quelques fils longitudinaux, un treillis, un garnissage ou une toison de fibres. Although it is generally sufficient that the support material consists only of the layer pierced with holes and of another continuous surface layer linked to the previous one by the mass of "sealing wax", it may be advantageous in certain cases to '' insert between these layers of the support material, in order to increase the mechanical resistance, a fabric, a few longitudinal threads, a trellis, a filling or a fleece of fibers.

On peut également utiliser la face extérieure de la couche du matériau-support qui présente une surface continue comme face visible de sorte que sur ladite surface on peut apposer des symboles ou des caractères ou meme des dessins, par exemple à des fins publicitaires.One can also use the external face of the layer of the support material which has a continuous surface as visible face so that on this surface one can affix symbols or characters or even designs, for example for advertising purposes.

La propagdtion d'un front de flammes dans le plan d'un élément isolant peut, suivant un mode de réalisation préféré de l'invention, être empêchée à coup sûr lorsque l'aire des trous percés dans les surfaces et l'aire des surfaces non percées de la couche extérieure sont dans un rapport compris entre 2 : 8 et 8 :
Selon l'invention, les trous peuvent être des trous isolés de relativement grandes dimensions. Mais on a également la possibilité de rassembler en groupes des trous de petites dimensions. Pour ces deux modes de réalisation, il est important qu'il existe, entre les différents trous isolés ou bien entre les différents groupes d'emplacements d'adhérence, des zones suffisamment grandes de surfaces non percées de trous, qui puissent empêcher de façon efficace un front de flammes de se propager plus loin.The propagation of a flame front in the plane of an insulating element can, according to a preferred embodiment of the invention, be prevented without fail when the area of the holes drilled in the surfaces and the area of the surfaces not drilled from the outer layer are in a ratio between 2: 8 and 8:
According to the invention, the holes can be insulated holes of relatively large dimensions. But we also have the possibility of grouping small holes in groups. For these two embodiments, it is important that there exist, between the different isolated holes or else between the different groups of adhesion locations, sufficiently large areas of surfaces not drilled with holes, which can effectively prevent a front of flames to spread further.

A cet égard les trous peuvent être répartis dans le plan de la couche du matériau-support de façon régulière ou de façon irrégulière. Ils peuvent en outre présenter des contours réguliers ou irréguliers, identiques ou non. On peut envisager de prévoir des ouvertures rectangulaires, rondes, ovales ou ayant un contour anguleux quelconque. In this regard the holes can be distributed in the plane of the layer of the support material in a regular or irregular manner. They can also have regular or irregular contours, identical or not. One can consider providing rectangular, round, oval or having any angular outline.

Les trous peuvent être formés par perforation ou par poinçonnage d'une couche du matériau-support présentant à l'état initial une surface continue. Les petits morceaux de matière qui sont ainsi découpés peuvent avantageusement être envoyées au recyclage
Il est en outre possible de former les trous en rapportant, suivant des zones, sur une couche du matériau-support de surface continue, des bandes de même matière que le matériau-support. On peut en outre envisager de former les trous en disposant en croix des bandes de même matière que le matériau-support.Ces bandes peuvent par exemple être déroulées au moment de l'élaboration du matériau-support de rouleaux pouvant être décalés transversalement par rapport à la couche du matériau-support déjà enduite de la "cire à cacheter" de sorte qu'on obtient alors des dessins dans lesquels
o les bandes du matériau-support se superposent en croix ou tout au moins suivant une forme s'approchant de celle-ci et on obtient de cette -manière des zones où la surface est percée de trous et des zones où la surface n'est pas percée.The holes can be formed by perforation or by punching a layer of the support material having in the initial state a continuous surface. The small pieces of material which are thus cut can advantageously be sent for recycling.
It is also possible to form the holes by adding, along zones, on a layer of the support material of continuous surface, strips of the same material as the support material. It is also possible to envisage forming the holes by placing strips of the same material as the support material in a cross pattern. These strips can, for example, be unrolled at the time of the preparation of the support material for rolls which can be offset transversely with respect to the layer of support material already coated with "sealing wax" so that drawings are obtained in which
o the strips of the support material overlap in a cross or at least in a shape approaching it and we obtain from this way areas where the surface is pierced with holes and areas where the surface is not not breakthrough.

Enfin un mode de réalisation avantageux de l'invention consiste aussi dans le fait que les trous 3 sont obtenus en pratiquant, dans une couche du matériau= support présentant une surface continue, des fentes transversales puis en-étirant ladite couche. Il est avantageux dans ce cas que les fentes transversales soient disposées en lignes et décalées les unes par rapport aux autres. Leur longueur dépend des dimensions que l'on souhaite donner aux trous, une fois ceux-ci réalisés. Les fentes ne doivent bien entendu pas s'étendre sur la totalité de la largeurdUne bande ou lé du matériau-support. Après exécution des fentes, on étend ou étire le lé dans sa totalité ou seulement le tronçon de lé dont on a besoin. Dans cette opération le lé ou le tronçon de lé se rétrécit et les fentes s'élargissent pour former des trous. C'est dans cet état que le lé ou le tronçon de lé est ensuite lié à une couche du matériau-support de surface continue. Finally, an advantageous embodiment of the invention also consists in the fact that the holes 3 are obtained by practicing, in a layer of the material = support having a continuous surface, transverse slots then by stretching said layer. It is advantageous in this case that the transverse slots are arranged in lines and offset from one another. Their length depends on the dimensions that one wishes to give to the holes, once they have been made. The slots must of course not extend over the entire width of a strip or strip of the support material. After execution of the slits, the strip is extended or stretched in its entirety or only the section of strip which is needed. In this operation the strip or the section of strip narrows and the slots widen to form holes. It is in this state that the strip or the section of the strip is then bonded to a layer of the support material of continuous surface.

L'invention sera mieux comprise par la description de certains de ses modes de réalisation, donnés ici à titre illustratif mais nullement limitatif, qui en sera faite ciwaprès à l'aide des figures annexées qui représentent
- la figure 1, en perspective et à échelle agrandie plusieurs fois, un tronçon d'un élément isolant selon l'invention en coupe verticale
- la figure 2, une vue de dessus à échelle plus petite d'un tronçon longitudinal d'une couche du matériau-support, percée de trous, d'un élément isolant

- les figures 4 et 5, en vue de dessus à échelle réduite, des tronçons longitudinaux d'une couche du matériau-support dans laquelle on a pratiqué des fentes transversales, respectivement avent et après étirage.The invention will be better understood from the description of some of its embodiments, given here by way of illustration but in no way limiting, which will be made of them below with the aid of the appended figures which represent
- Figure 1, in perspective and on an enlarged scale several times, a section of an insulating element according to the invention in vertical section
- Figure 2, a top view on a smaller scale of a longitudinal section of a layer of the support material, pierced with holes, of an insulating element
FIG. 3, also a top view on a reduced scale of a longitudinal section of a layer of the support material, pierced with holes, according to another embodiment, and
- Figures 4 and 5, in top view on a reduced scale, longitudinal sections of a layer of the support material in which we have made transverse slots, respectively before and after stretching.

L'élément isolant 1 dont un tronçon est représenté sur la figure 1 se compose d'un matériausupport 2 comportant trois couches et d'un matériau d'isolation 3 lié au matériau-support 2. The insulating element 1, a section of which is shown in FIG. 1, consists of a support material 2 comprising three layers and an insulation material 3 linked to the support material 2.

Le matériau-support 2 comporte une couche extérieure 4 présentant une surface continue et réalisée en feuille mince d'aluminium ainsi qu'une couche 6 percée de trous 5, laquelle est également en feuille mince d'aluminium. Les deux feuilles d'aluminium 4, 6 sont liées entre elles par une masse 7 en polyéthylène, permettant d'assurer le cachetage, qui est étendue suivant une surface continue sur la couche extérieure 4. The support material 2 comprises an outer layer 4 having a continuous surface and made of thin aluminum sheet as well as a layer 6 pierced with holes 5, which is also made of thin aluminum sheet. The two aluminum sheets 4, 6 are linked to each other by a polyethylene mass 7, making it possible to ensure sealing, which is extended along a continuous surface on the outer layer 4.

Au moment de la liaison du matériau-support 2 avec le matériau d'isolation 3, par exemple en laine minérale, le matériau-support 2 est chauffé suffisamment pour que le polyéthylène 7 se plastifie et pour que par suite il se lie avec le matériau dtisolation 3 dans les zones où se trouvent les trous 5. Après refroidissement, le matériau d'isolation 3 adhère solidement au matériausupport 2. At the time of bonding of the support material 2 with the insulation material 3, for example mineral wool, the support material 2 is heated sufficiently so that the polyethylene 7 becomes plasticized and so that it therefore binds with the material insulation 3 in the areas where the holes are located 5. After cooling, the insulation material 3 adheres securely to the support material 2.

On peut voir sur la figure 2 que les trous 5 pratiqués dans la couche du matériau-support-6 qui se trouve en contact avec le matériau d'isolation 3 peuvent avoir diverses formes et être groupés différemment. It can be seen in FIG. 2 that the holes 5 made in the layer of the support material-6 which is in contact with the insulation material 3 can have various shapes and be grouped differently.

Ceci veut dire que l'on peut prévoir des ouvertures Sa isolées réparties sur la surface. Les ouvertures Sa peuvent avoir des contours identiques -ou non; Elles peuvent être réparties de façon régulière ou non sur la longueur d'un élément isolant 1 ou bien encore être rassemblées en groupes 5b. -
Comme le montre la figure 3, on peut envisager d'obtenir les trous 5 en disposant en croix des bandes du matériau-support 8, ces bandes 8 constituant alors l couche 6 du matériau-support.This means that it is possible to provide isolated openings Sa distributed over the surface. Sa openings can have identical contours - or not; They can be distributed evenly or not over the length of an insulating element 1 or even be grouped in groups 5b. -
As shown in FIG. 3, it is possible to envisage obtaining the holes 5 by placing strips of the support material 8 in a cross, these strips 8 then constituting the layer 6 of the support material.

Sur la figure 4 est représentée une couche 6- du matériau-support qui est munie de fentes transversales 9 disposées en lignes et décalées les unes par rapport aux autres. Pour obtenir les trous, la couche de matériausupport est alors allongée ou étirée de sorte que les fentes 9 s'élargissent pour donner des trous 5c #cependant que la couche du matériau-support se rétrécit. In Figure 4 is shown a layer 6- of the support material which is provided with transverse slots 9 arranged in lines and offset from each other. To obtain the holes, the support material layer is then elongated or stretched so that the slots 9 widen to give holes 5c # except that the layer of the support material shrinks.

Dans tous les modes de réalisation, il est important que la distance entre deux trous isolés 5, Sa, 5c voisins ou entre les groupes 5b d'ouvertures, voisins, soit suffisamment grande pour que ces zones superficielles constituent un barrage efficace à la propagation des flammes. In all the embodiments, it is important that the distance between two neighboring isolated holes 5, Sa, 5c or between the groups 5b of neighboring openings, is large enough for these surface areas to constitute an effective barrier to the propagation of flames.

Comme il va de soi et comme il résulte d'ailleurs déjà de ce qui précède, l'invention ne se limite nullement à celui de ses modes d'application, non plus qu'à ceux des modes de réalisation de ses diverses par-ties, ayant été plus particulièrement envisagés ; elle en embrasse, au contraire, toutes les variantes.  As goes without saying and as it already follows from the foregoing, the invention is in no way limited to that of its modes of application, no more than to those of the embodiments of its various parts. , having been more particularly envisaged; on the contrary, it embraces all its variants.
