Abstract

The insulating material consists of a first layer (2) of a non woven felted material weighing preferably between 350 and 4000 g/sq m, and a second layer (3) of a spun calendered non-woven material weighing preferably between 60 and 150 g/sq m. The two layers are attached to either side of a layer of plastic mesh (4) weighing preferably between 80 and 120 g/sq m. After laying the insulating material a coating (C) is poured onto it and allowed to set before laying tiles (D).

Description

La présente invention a pour objet un nouvel isolant phonique et un procédé pour réaliser un carrelage mettant en oeuvre un tel isolant phonique. The present invention relates to a new sound insulator and a method for producing a tiling using such a sound insulator.

On connaît des isolants phoniques constitués par une couche épaisse d'un matériau fibreux, destinés à être mis en place sous un parquet flottant par exemple. Acoustic insulators are known which consist of a thick layer of fibrous material, intended to be placed under a floating parquet for example.

L'isolant phonique selon l'invention se caractérise par le fait qu'il comporte
- une première couche de non-tissé présentant une masse par unité de surface comprise entre 200 et 1000 g/m2, de préférence entre 350 et 400g/m2,
- une deuxième couche de non-tissé présentant une masse par unité de surface comprise entre 40 et 200 g/m2, de préférence entre 60 et 150g/m2,
et par le fait que lesdites première et deuxième couches sont fixées respectivement de part et d'autre d'une structure réticulaire en matière plastique.The sound insulation according to the invention is characterized in that it comprises
a first layer of nonwoven having a mass per unit area of between 200 and 1000 g / m2, preferably between 350 and 400 g / m2,
a second layer of nonwoven having a mass per unit area of between 40 and 200 g / m2, preferably between 60 and 150 g / m2,
and by the fact that said first and second layers are fixed respectively on either side of a plastic reticular structure.

Grâce à l'invention, les structures des première et deuxième couches peuvent être adaptées respectivement à la nature du support sur lequel est posé l'isolant et à celle du revêtement recouvrant l'isolant. Thanks to the invention, the structures of the first and second layers can be adapted respectively to the nature of the support on which the insulation is placed and to that of the coating covering the insulation.

Dans une réalisation préférée, ladite grille présente une masse par unité de surface comprise entre 40 et 300 g/m2, de préférence entre 60 et 120g/m'.  In a preferred embodiment, said grid has a mass per unit area of between 40 and 300 g / m 2, preferably between 60 and 120 g / m 2.

Toujours dans une réalisation préférée, la première couche de non-tissé est constituée par un non-tissé aiguilleté et la deuxième couche de non-tissé est constituée par un non-tissé spun calandré. Still in a preferred embodiment, the first layer of nonwoven is constituted by a needled nonwoven and the second layer of nonwoven is constituted by a calendered spun nonwoven.

L'isolant phonique selon l'invention présente de bonnes caractéristiques sur le plan de l'isolation phonique, est relativement léger et permet en plus le coulage d'une chape directement à son contact. The sound insulation according to the invention has good characteristics in terms of sound insulation, is relatively light and also allows the pouring of a screed directly in contact with it.

En outre, l'isolant phonique laisse avantageusement respirer le support sur lequel il est posé, ce qui est utile lorsque le support est constitué par une dalle coulée peu de temps avant la pose de l'isolant phonique. In addition, the sound insulation advantageously allows the support on which it is placed to breathe, which is useful when the support consists of a poured slab shortly before the installation of the sound insulation.

L'invention a encore pour objet un procédé caractérisé par le fait qu'il comporte les étapes consistant à
- déposer un isolant phonique tel que précité sur le support à recouvrir, la première couche de non-tissé étant au contact de ce support,
- couler une chape sur l'isolant phonique,
- laisser sécher la chape,
- poser un carrelage sur la chape.The invention also relates to a method characterized in that it comprises the steps consisting in
depositing a sound insulator as mentioned above on the support to be covered, the first layer of nonwoven being in contact with this support,
- pour a screed on the sound insulation,
- let the screed dry,
- lay a tile on the screed.

L'invention sera mieux comprise à la lecture de la description détaillée qui suit, et à l'examen du dessin annexé sur lequel la figure unique représente de façon partielle et schématique un isolant phonique selon l'invention, la deuxième couche de non-tissé étant partiellement désolidarisée de la grille dans un coin pour laisser apparaitre cette dernière. The invention will be better understood on reading the detailed description which follows, and on examining the appended drawing in which the single figure partially and schematically represents a sound insulator according to the invention, the second layer of nonwoven being partially detached from the grid in a corner to reveal the latter.

On a représenté sur la figure annexée des dalles D de carrelage fixées sur une chape C recouvrant un isolant phonique conforme à l'invention. There is shown in the appended figure tiles D of tiling fixed on a screed C covering a sound insulator according to the invention.

Cet isolant phonique présente une structure composite constituée par
- une première couche 2 d'un non-tissé aiguilleté à fibres synthétiques dont la masse par unité de surface est comprise entre 350 et 400 g/ml
- une deuxième couche 3 de non-tissé à fibres synthétiques spun calandré présentant une masse par unité de surface comprise entre 60 et 150 g/m2, ces première et deuxième couches étant fixées de part et d'autre d'une grille 4 en polyéthylène ayant une masse par unité de surface comprise entre 80 et 120 g/m2.This sound insulation has a composite structure consisting of
- a first layer 2 of a needled nonwoven with synthetic fibers whose mass per unit area is between 350 and 400 g / ml
a second layer 3 of nonwoven with synthetic spun calendered fibers having a mass per unit area of between 60 and 150 g / m2, these first and second layers being fixed on either side of a grid 4 of polyethylene having a mass per unit area of between 80 and 120 g / m2.

Pour fabriquer l'isolant phonique, on assemble d'abord l'une des couches à la grille après avoir fait fondre superficiellement cette dernière sur une face, puis on fait fondre superficiellement l'autre face de la grille pour assembler l'autre couche. To make the sound insulation, one of the layers is first assembled to the grid after having melted the latter on one side, then the other side of the grid is melted to assemble the other layer.

La première couche 2 est destinée à reposer sur le support à recouvrir tandis que la chape C est coulée au contact de la deuxième couche 3. The first layer 2 is intended to rest on the support to be covered while the screed C is poured in contact with the second layer 3.

La chape C peut présenter 5 mm d'épaisseur par exemple. The yoke C may have a thickness of 5 mm for example.

La grille 4 est réalisée par un procédé d'extrusion connu en lui-même, et présente dans l'exemple considéré des mailles en forme de losange.  The grid 4 is produced by an extrusion process which is known per se, and in the example under consideration has diamond-shaped meshes.

A titre d'exemple, l'épaisseur de la première couche est de l'ordre de 3 mm, l'épaisseur de la grille de l'ordre de 1 mm et l'épaisseur de la deuxième couche de l'ordre de 1 mm également. For example, the thickness of the first layer is of the order of 3 mm, the thickness of the grid of the order of 1 mm and the thickness of the second layer of the order of 1 mm also.

Le non-tissé constituant la deuxième couche 3 permet d'éviter les infiltrations du matériau constituant la chape C à travers l'isolant phonique. The nonwoven constituting the second layer 3 makes it possible to avoid infiltration of the material constituting the screed C through the sound insulation.

Bien entendu, l'invention n'est pas limitée à l'exemple de réalisation qui vient d'être décrit. Of course, the invention is not limited to the embodiment which has just been described.

On peut notamment utiliser une grille présentant une structure réticulaire différente.  One can in particular use a grid having a different reticular structure.
