Isolation thermique extérieure pour toitures.Exterior thermal insulation for roofs.
La présente invention concerne une isolation thermique extérieure pour toitures du type indiqué dans la revendication 1.The present invention relates to external thermal insulation for roofs of the type indicated in claim 1.
5 Habituellement, une isolation extérieure pour toitures comporte une couche de cailloux ou de fins galets en guise de ballast au-dessus des blocs isolants. Cette couche de ballast remplit deux*fonctions, à savoir, en premier lieu, empêcher un vide 10 situé au-dessus de la toiture de soulever les blocs et, en second lieu, réduire l'effet d'érosion exercé par la lumière solaire sur la matière plastique des blocs. La couche de ballast ne contribue pas à assurer l'isolation thermique.5 Usually, exterior insulation for roofs comprises a layer of pebbles or fine pebbles as ballast over the insulating blocks. This layer of ballast fulfills two * functions, namely, firstly, to prevent a vacuum 10 located above the roof from lifting the blocks and, secondly, to reduce the erosion effect exerted by sunlight on the plastic of the blocks. The ballast layer does not help provide thermal insulation.
15 Un objet de la présente invention est de fournir une isolation pour toitures du type indiqué ci-dessus, isolation dans laquelle, outre ses fonctions connues, la couche de ballast contribue également pour une large part à assurer l'isolation thermique de 20 la toiture.An object of the present invention is to provide insulation for roofs of the type indicated above, insulation in which, in addition to its known functions, the ballast layer also largely contributes to ensuring the thermal insulation of the roof. .
Suivant l'invention, on réalise cet objet dans une isolation extérieure selon la partie caractérisante de la revendication 1.According to the invention, this object is produced in external insulation according to the characterizing part of claim 1.
Des dalles de laine minérale sont en mesure 25 d'égaliser les différences de pression dues à leur structure fibreuse. En conséquence, la laine minérale fait office de ballast et elle augmente le poids des blocs de mousse plastique situés en dessous, les empêchant ainsi de se soulever lorsqu'un vide existe au-30 dessus de la toiture. La laine minérale liée résiste aux intempéries et n'est pas décomposée par la lumière solaire, si bien qu'elle remplit les conditions habituellement imposées à un ballast. En réalité, la laine minérale seule pourrait être utilisée comme isolation 35 jj thermique extérieure pour toitures, mais ses propriétés 2 , * ! isolantes sont réduites de 25-40% en raison de la struc ture fibreuse qui permet la diffusion. La combinaison de la laine minérale et d'une mousse plastique résistant à la diffusion assure une importante réduction des 5 pertes par diffusion dans la laine minérale, de sorte que l'on obtient des propriétés d'isolation proches de la valeur théorique.Mineral wool tiles are able to equalize pressure differences due to their fibrous structure. As a result, the mineral wool acts as a ballast and increases the weight of the plastic foam blocks located below, thereby preventing them from rising when a vacuum exists above the roof. Bound mineral wool is weather resistant and is not broken down by sunlight, so it meets the conditions usually imposed on a ballast. In reality, mineral wool alone could be used as external thermal insulation for roofs, but its properties 2, *! insulation are reduced by 25-40% due to the fibrous structure which allows diffusion. The combination of mineral wool and diffusion-resistant plastic foam provides a significant reduction in diffusion losses in mineral wool, so that insulation properties close to the theoretical value are obtained.
De préférence, l'isolation est conçue comme indiqué dans la revendication 2. Ce système simplifie 10 la manutention au cours de la construction et également lorsque les blocs doivent être enlevés, par exemple, au cours d'une inspection de la membrane imperméable ! à 11 e au.Preferably, the insulation is designed as claimed in claim 2. This system simplifies handling during construction and also when the blocks are to be removed, for example, during an inspection of the waterproof membrane! at 11 th to.
L'invention sera décrite ci-après plus en 15 détail en se référant à l'unique dessin annexé qui est une vue en coupe d'une isolation thermique extérieure selon l'invention.The invention will be described below in more detail with reference to the single accompanying drawing which is a sectional view of an external thermal insulation according to the invention.
! Sur une structure 1 supportant la charge, par exemple, un tablier en béton, on a déposé une mem-20 brane 2 imperméable à l'eau, par exemple, un feutre r bitumé. Cette structure ne limite nullement l'inven tion et les exemples ci-dessus illustrent simplement j des matériaux de construction classiques utilisés dans l'industrie du bâtiment. Aucune condition n'est imposée 25 à la structure 1 ou à la membrane 2 imperméable à l'eau, ! hormis leur aptitude à supporter les charges normales | et leur étanchéité à l'eau. Sur la structure 1 et t.! On a structure 1 supporting the load, for example, a concrete deck, a waterproof mem-20 brane 2 was deposited, for example, a bituminized felt. This structure does not limit the invention in any way and the examples above simply illustrate conventional building materials used in the building industry. No condition is imposed on the structure 1 or on the waterproof membrane 2,! apart from their ability to bear normal loads | and their water tightness. On structure 1 and t.
| · la membrane 2, on pose des blocs d'isolation thermique ! 3 constitués d'une mousse plastique ou d'une matière j 30 plastique expansée. On sait que cette couche possède | un haut degré d'imperméabilité à la vapeur d'eau et j.| · Membrane 2, thermal insulation blocks are installed! 3 made of plastic foam or expanded plastic.

} qu'elle n'est pas hygroscopique. Parmi les matériaux appropriés, il y a la mousse de polyuréthane à cellules fermées ou éventuellement des granulés comprimés de 35 polystyrène expansé. Afin d'empêcher un vide se créant t ψ * j } 3 \ S ' î au-dessus du tablier de soulever les blocs de mousse I 3, on prévoit, sur ces derniers, une couche de ballast ! ayant des propriétés d'égalisation de pression. Suivant | l'invention, cette couche est constituée de dalles 4 l 3 de laine minérale avec des fibres qui sont liées à | leurs intersections au moyen d'un agent liant. Il est préférable d'utiliser une laine minérale ayant une résistance mécanique suffisante pour supporter le poids s d'une personne marchant avec des chaussures souples.} that it is not hygroscopic. Among the suitable materials are closed cell polyurethane foam or possibly compressed granules of expanded polystyrene. In order to prevent a vacuum being created t ψ * j} 3 \ S 'î above the deck to lift the foam blocks I 3, a layer of ballast is provided on the latter! having pressure equalizing properties. Next | the invention, this layer consists of slabs 4 l 3 of mineral wool with fibers which are linked to | their intersections by means of a binding agent. It is best to use mineral wool with sufficient mechanical strength to support the weight of a person walking with flexible shoes.
| 10 Cette condition est remplie par une laine minérale ] ayant un poids spécifique de 150 kg/m3, pour obtenir I ainsi un ballastage de 20 kg/m2 au moyen d'une dalle d'une épaisseur de 135 mm. La laine minérale protège | l'isolation en mousse plastique contre la lumière solai- 15 re et cette isolation protège également la laine minérale contre la diffusion de la vapeur si bien que, dans i la pratique, les deux matériaux d'isolation ont à peu ! près la capacité d'isolation théorique.| 10 This condition is fulfilled by a mineral wool] having a specific weight of 150 kg / m3, to thus obtain ballasting of 20 kg / m2 by means of a slab with a thickness of 135 mm. Mineral wool protects | the plastic foam insulation against sunlight and this insulation also protects the mineral wool from vapor diffusion so that, in practice, the two insulation materials have little! close to the theoretical insulation capacity.
Il est possible de poser les deux couches 20 du matériau isolant avec des joints décalés, mais une inspection de la membrane 2 étanche à l'eau est plus i simple si les joints des deux couches sont mutuellement en alignement et, en particulier, si la laine minérale i f et la mousse plastique sont collées ensemble en un 25 Λbloc à deux couches.It is possible to lay the two layers 20 of the insulating material with offset joints, but an inspection of the waterproof membrane 2 is simpler if the joints of the two layers are in alignment with each other and, in particular, if the yew mineral wool and plastic foam are glued together in a 25 Λ two-layer block.
