Description

Membrane thermo-acoustique et isolante Thermo-acoustic and insulating membrane
La présente invention a pour objet une membrane thermo-acoustique radiante, comprenant une ou plusieurs couche(s) de support de polyéthylène, polypropylène, de polyester ou de métal tel que de l'aluminium, du bronze, du cuivre, sur laquelle ou lesquelles ou entre lesquelles est laminée une couche de granulats de caoutchouc de grosseur variant entre 2 à 30 mèches, issus de pneus hors d'usage ou autres. Des composantes fibreuses telles que des fibres de bois, fibres minérales, fibres synthétiques ou fibres végétales peuvent être laminées ou mélangées avec les granulats pour assurer une meilleure adhérence de ces derniers sur la membrane.The present invention relates to a thermo-acoustic radiant membrane, comprising one or more support layer (s) of polyethylene, polypropylene, polyester or metal such as aluminum, bronze, copper, on which or or between which is laminated a layer of rubber granules of size ranging from 2 to 30 wicks, from tires out of use or other. Fibrous components such as wood fibers, mineral fibers, synthetic fibers or plant fibers can be laminated or mixed with the aggregates to ensure better adhesion of the latter to the membrane.
En pratique, les granulats de caoutchouc et/ou les fibres sont fixés à la couche de base à l'aide de bitume élastomère à chaud et/ou de latex et/ou de polyuréthane. L'épaisseur du laminât de granulats sur la couche est de Va" à 5A" (environ 3 mm à 16 mm).In practice, the rubber granules and / or fibers are attached to the base layer with hot elastomeric bitumen and / or latex and / or polyurethane. The thickness of the laminate of aggregates on the layer is 5 to 5 mm (about 3 mm to 16 mm).
Les granulats de caoutchouc et/ou les fibres peuvent être déposés sur toute la surface de la couche de support ou seulement une partie de celle-ci, qui a alors une forme de damier avec une partie sans granulat et une partie avec granulats. Les granulats peuvent aussi être disposés en rangées, les rangées de granulats étant par exemple de 6" (environ 15 cm), les rangées intermédiaires de 2' (environ 5 cm)'. La largeur et la distance des rangées ou la disposition en damier peut bien entendu varier en fonction des besoins.The rubber granules and / or the fibers may be deposited on the entire surface of the support layer or only a portion thereof, which then has a checkerboard shape with a non-granulated portion and a granulated portion. The aggregates may also be arranged in rows, the rows of aggregates being for example 6 "(about 15 cm), the intermediate rows 2 '(about 5 cm) .1 The width and distance of the rows or the checkerboard arrangement can of course vary according to the needs.
La membrane selon l'invention est destinée à être installée sur un plancher, sous une chape de béton d'une épaisseur de préférence égale à 1 Vz" (environ 38 mm), sous une chape de ciment léger auto-nivellant ou sous une feuille de contreplaqué. Une fois installée, la membrane permet de donner une suspension au plancher, en plus de permettre une optimisation thermique, radiante et acoustique de ce même plancher.The membrane according to the invention is intended to be installed on a floor, under a concrete screed of a thickness preferably equal to 1 Vz "(about 38 mm), under a self-leveling lightweight cement screed or under a sheet Once installed, the membrane provides a suspension to the floor, in addition to allowing a thermal, radiant and acoustic optimization of the same floor.
En usage, elle agit comme un ressort entre le fini plancher et sa structure.In use, it acts as a spring between the floor finish and its structure.
La membrane selon l'invention est donc particulièrement bien adaptée pour un usage dans le domaine de la construction résidentielle. Elle peut en fait s'adapter à toutes les structures de bois, de béton et de métal. Elle peut également recevoir divers produits de fini de plancher tels que du bois, céramique ou autres. Tel que précédemment mentionné, le rôle principal de la membrane selon l'invention est d'insonoriser les planchers contre les bruits d'impact tout en étant radiante.The membrane according to the invention is therefore particularly well suited for use in the field of residential construction. It can actually adapt to all structures of wood, concrete and metal. It can also receive various floor finish products such as wood, ceramics or others. As previously mentioned, the main role of the membrane according to the invention is to soundproof the floors against impact noise while being radiant.
Des tests acoustiques effectués sur des échantillons préparés par le Demandeur ont permis d'établir des performances de haut niveau (par exemple : un indice d'isolement aux bruits d'impact (FIIC) aussi élevé que 65 et un indice d'isolement aux bruits aériens (FSTC) aussi élevé que 62).Acoustic tests on samples prepared by the Applicant have established high-level performance (for example: an impact noise isolation index (FIIC) as high as 65 and a noise isolation index (FSTC) as high as 62).

Le plancher ainsi réalisé comprenait, en descendant depuis sa surface supérieure vers le bas :The floor thus realized included, descending from its upper surface downwards:
- une couche de bois de finition de 3A" (environ 19 mm);- a layer of wood finish of 3 A "(about 19 mm);
- un panneau de bois aggloméré de haute densité de Va" (environ 16 mm);- a board of high density wood of Va "(about 16 mm);
- une dalle de béton de VΛ" (environ 38 mm);- a V d "concrete slab (approximately 38 mm);
- la membrane selon l'invention telle que décrite ci-dessus, d'une épaisseur de 9/16" (environ 15 mm);the membrane according to the invention as described above, with a thickness of 9/16 "(approximately 15 mm);
- un panneau de bois aggloméré haute densité de %" (environ 16 mm); et- a high density fibreboard of% "(about 16 mm), and
- des poutrelles ajourées de 13" (environ 330 mm), entre lesquelles se trouvaient de la laine soufflée), ces poutrelles étant associées à des barres résilientes de Yz" (environ 13 mm) supportant un panneau de placoplâtre ignifuge de %" (environ 16 mm).- 13 "(approximately 330 mm) openwork beams, between which were blown wool), these beams being associated with Yz" resilient bars (approximately 13 mm) supporting a% "fireproof plasterboard panel (approx. 16 mm).
Les tests effectués ont amené aux résultats suivants :The tests carried out led to the following results:
FIIC (Indice d'isolement aux bruits d'impact - Field impact insulation class) = 65 FSTC (Indice d'isolement aux bruits aériens - Field sound transmission class) = 62FIIC (Field impact insulation class) = 65 FSTC (Field sound transmission class) = 62
Ces tests ont donc confirmé que la membrane selon l'invention a bel et bien créé un excellent bris acoustique entre la dalle de béton et la structure du mur, en plus de former un bassin retenant l'eau lors de la mise en place du béton. These tests have confirmed that the membrane according to the invention has indeed created an excellent acoustic break between the concrete slab and the wall structure, in addition to forming a basin retaining water during the establishment of concrete .
