Abstract
Description
L'invention a pour objet un nouveau matériau isolant thermique composite, à base de fibres minérales, plus particulièrement un matériau comprenant une bande de feutre en fibres minérales, recouverte sur l'une de ses faces d'une feuille protectrice pratiquement étanche à l'air et aux vapeurs. Un tel matériau peut être avantageusement utilisé pour l'isolation thermique de toitures, de planchers ou de parois à ossature en bois.The subject of the invention is a new composite thermal insulating material, based on mineral fibers, more particularly a material comprising a strip of felt made of mineral fibers, covered on one of its faces with a protective sheet which is practically waterproof. air and vapor. Such a material can advantageously be used for thermal insulation of roofs, floors or walls with wooden frames.
Diverses solutions ont été proposées à ce jour pour résoudre de façon optimale le problème de l'isolation thermique des toitures. La technique la plus courante consiste à disposer entre les pièces maitresses de la toiture un matériau isolant essentiellement fait de fibres minérales, telle de la laine de verre ou de la laine de roche par exemple. Un tel matériau peut se présenter sous formes de plaques ou de rouleaux dont les dimensions sont plus ou moins adaptées à la situation rencontrée. Une fois mise en place, la laine de verre ou de roche peut être fixée à des éléments de toitures au moyen de clous ou d'agrafes, par exemple, ou se maintenir en place sous l'effet d'une certaine compression latérale.Various solutions have been proposed to date to optimally solve the problem of thermal insulation of roofs. The most common technique consists in placing between the center pieces of the roof an insulating material essentially made of mineral fibers, such as glass wool or rock wool for example. Such a material can be in the form of plates or rolls whose dimensions are more or less adapted to the situation encountered. Once in place, the glass or rock wool can be attached to roofing elements by means of nails or staples, for example, or be held in place under the effect of a certain lateral compression.
Dans certains cas, les panneaux ou feutres à base de fibres minérales peuvent être doublés, sur l'une de leurs faces, d'une feuille protectrice faisant office de pare-vapeur. Une telle feuille protectrice peut être soit disposée séparément, au cours d'une manipulation complémentaire, soit être préencollée à la face externe de la masse de fibres minérales : les feuilles pare-vapeur connues à ce jour sont en papier, en aluminium ou encore en matériau composite à base de papier ou d'aluminium par exemple. Dans certains cas, notamment lorsque le matériau isolant se présente sous forme de rouleaux, la feuille protec trice comporte des languettes de fixation latérale. Une fois disposé entre deux poutres d'une toiture par exemple, ledit matériau est maintenu en place au moyen des languettes clouées ou agrafées à même la poutre.In some cases, the panels or felts based on mineral fibers can be lined, on one of their faces, with a protective sheet acting as a vapor barrier. Such a protective sheet can either be placed separately, during additional handling, or be pre-glued to the external face of the mass of mineral fibers: the vapor barrier sheets known to date are made of paper, aluminum or else composite material based on paper or aluminum for example. In some cases, especially when the insulating material is in the form of rolls, the protective sheet trice has lateral fixing tabs. Once placed between two beams of a roof for example, said material is held in place by means of tabs nailed or stapled to the same beam.
Les feutres ou panneaux sans revêtement sont maintenus en place par la compression latérale de la masse de fibres minérales.The uncoated felts or panels are held in place by lateral compression of the mass of mineral fibers.
On a cependant constaté de nombreuses imperfections quant à l'isolation thermique ainsi recherchée. C'est ainsi qu'au cours de vérifications a posteriori, on constate que bon nombre d'espaces de toitures ne sont pas remplis, ce que l'emploi de pare-vapeur en papier ou aluminium ne permettait pas de déceler lors de la pose, étant donné l'opacité du matériau utilisé. En effet, bien que les toitures soient construites sur la base d'éléments de dimensions standardisées (espaces entre deux poutres par exemple), des inégalités subsistent et des feutres de dimensions standard ne peuvent pas s'adapter à toutes les situations. Ceci se marque encore plus nettement dans des bâtiments anciens et sur des toitures à pans multiples, à la charpente relativement complexe.However, numerous imperfections have been noted with regard to the thermal insulation thus sought. This is how, during retrospective checks, it is noted that a good number of roof spaces are not filled, which the use of vapor barrier made of paper or aluminum did not make it possible to detect during installation. , given the opacity of the material used. Indeed, although the roofs are built on the basis of elements of standardized dimensions (spaces between two beams for example), inequalities remain and felts of standard dimensions cannot adapt to all situations. This is even more marked in old buildings and on multi-sided roofs, with a relatively complex frame.
Les imperfections dans l'isolation thermique mentionnées plus haut sont encore accentuées sous la pression d'un fort vent externe et, dans de nombreux cas, les normes d'isolation actuelles et celles en préparation ne sont plus respectées. Actuellement, l'homme de métier est dépourvu de solution simple et efficace permettant de surmonter les inconvénients relevés plus haut, notamment d'un matériau garantissant lors d'une seule opération de pose isolation thermique optimum et étanchéité à l'air et aux vapeurs.The imperfections in the thermal insulation mentioned above are further accentuated under the pressure of a strong external wind and, in many cases, the current insulation standards and those in preparation are no longer respected. Currently, the skilled person is devoid of a simple and effective solution to overcome the drawbacks noted above, in particular of a material guaranteeing during a single installation operation optimum thermal insulation and air and vapor tightness.
Une solution nouvelle et originale est proposée à l'aide d'un matériau isolant thermique selon la revendication 1. La planche de dessin annexée illustre à titre d'exemple l'une des exécutions de l'invention :

- . figure 2 : est une vue en plan (de dessus) de ce même matériau,

- . FIG. 2: is a plan view (from above) of this same material,
- . Figure 3: is an illustration of the use of the material according to the invention, for the thermal insulation of a roof.
Selon l'invention, le matériau isolant comprend une bande de feutre 1, de préférence rectiligne, en fibres minérales. A titre de fi bres minérales, on peut avantageusement utiliser de la laine de verre ou de la laine de roche, ou encore toute autre fibre minérale appropriée. Dans une exécution préférentielle de l'invention, on utilise de la laine de verre dont la masse volumique peut être avantageusement comprise entre 6 et 18 kg/m³ environ. Il s'agit là d'un matériau facile d'emploi et aisément compressible, soit latéralement lors de sa mise en place entre deux poutres, soit pour l'emballage des rouleaux en usine (taux de compression de 2,5 à 5 fois).According to the invention, the insulating material comprises a
La bande 1 comporte en outre, sur sa face externe 2 (c'est-à-dire du côté de l'usager) une feuille protectrice 3 faite d'un matériau polymère translucide, voire transparent selon les cas, ignifugé. Un tel matériau doit être en effet translucide sinon transparent, pour permettre le contrôle visuel de l'insertion de la bande 1 entre deux poutres par exemple. Il doit être en outre difficilement combustible pour des raisons de normes et de sécurité fort compréhensibles. Les fumées de sa combustion ne doivent pas contenir de résidus toxiques comme des résidus chlorés par exemple. En outre, le taux d'opacité de l'air par les fumées de sa combustion sera minimum, soit compris entre 0 et 50%.The
On utilise de préférence un matériau du type polyoléfine tel le polyéthylène ou le polypropylène, ignifugé au moyen de techniques courantes. On peut utiliser de façon avantageuse une feuille de polyéthylène dont l'épaisseur varie de 0,07 à 0,7 mm ou plus selon les cas. De telles feuilles protectrices en polyéthylène présentent la résistance mécanique souhaitée pour le maintien en place et la manipulation du matériau selon l'invention ; simultanément, elles possèdent une souplesse suffisante pour ne pas être trouées ou déchirées accidentellement lors des opérations de pose ou une fois le matériau isolant mis en place. Une telle souplesse ne se retrouve pas dans les pare-vapeur connus, en papier ou en aluminium.A material of the polyolefin type, such as polyethylene or polypropylene, is preferably used, flame retarded by means of current techniques. One can advantageously use a polyethylene sheet whose thickness varies from 0.07 to 0.7 mm or more depending on the case. Such protective polyethylene sheets have the mechanical strength desired for holding in place and handling the material according to the invention; at the same time, they have sufficient flexibility so as not to be punctured or torn accidentally during the laying operations or once the insulating material is in place. Such flexibility is not found in known vapor barriers, paper or aluminum.
Selon l'invention, la feuille protectrice 3 est de dimensions telles qu'elle dépasse de part et d'autre de la bande 1, de sorte que les portions latérales excédentaires 4, 5 de feuille protectrice 3 fassent office d'organe de fixation du matériau isolant (voir à ce propos figure 3). Cette fixation peut être réalisée à l'aide de tous moyens connus tels des clous en "U", des agrafes ou des joints auto-collants par exemple. Des joints d'étanchéité complémentaires en matériau polymère compatible peuvent être en outre disposés entre deux languettes adjacentes, qui seront alors superposées lors de la pose du matériau selon l'invention. On peut ainsi assurer une étanchéité à l'air optimum, notamment à de l'air sous pression tel un fort vent externe.According to the invention, the
Selon l'invention finalement, la feuille protectrice 3 n'adhère qu'à la portion centrale 6 de la face externe 2 de la bande de feutre 1. De la sorte, on ménage sur ladite face 2 deux zones latérales longitudinales 7, 8 libres de toute adhérence. La portion correspondante de la bande de feutre peut être alors aisément comprimée latéralement (flèches sur figures 1 et 2), de plusieurs centimètres par exemple, pour s'adapter aux erreurs de parallèlisme de deux poutres ou à toute autre disparité rencontrée dans la construction d'une toiture charpentée. Dans la zone d'adhérence 6 réservée, la feuille 3 peut être simplement collée à la face externe 2 de la bande 1. Cet encollage peut être réalisé en pleine surface, par points distribués symétriquement dans ladite zone 6 ou par bandes ou stries parallèles. Il existe dans le commerce spécialisé des colles présentant les qualités requises pour la fabrication du matériau selon l'invention.According to the invention finally, the
