Comment réduire le bruit dans une cage d'escalier ?

L’isolation acoustique d’un escalier consiste à réduire la propagation des bruits à l’intérieur du logement. Pour réaliser une isolation phonique de l’escalier, vous allez vous appuyer sur la loi de masse, et surtout la loi de masse – ressort – masse. La première utilise des matériaux massifs destinés à absorber les bruits. La deuxième loi, plus intéressante pour l’isolation phonique des escaliers en rénovation, atténue les bruits sans alourdir l’escalier. La cage d’un escalier en métal est une chambre d’écho puissante pour les bruits que font les pas sur les marches. Poser sur les murs des panneaux ou des plaques de produit isolant réduit le phénomène. Utilisez au choix des plaques d’isolant phonique, du tissu phonique tendu sur des cadres en bois et garnis de laine minérale, des panneaux d’isolant à découper. Solution 1 : isolation acoustique par revêtement sur l’escalier Isoler des escaliers en métal qui font trop de bruit dans une maison commence par la pose d’un revêtement isolant : installation d’isolants acoustiques sur les marches ; pose d’isolants acoustiques sous les marches. Achetez un produit autocollant ou un isolant à coller. Différents matériaux isolants existent, que vous pouvez découper facilement à la forme de chaque marche : tapis de sol en bitume modifié en polymère ; plaques d’élastomère de polyuréthane ; tapis anti-vibrations absorbant acoustique ; plaques de caoutchouc mâché et fibres synthétiques. Vous pouvez exploiter le potentiel isolant des matières suivantes : laine minérale ; mousse acoustique ; plaque acoustique ; dalle acoustique. On joue ici avec le pouvoir d’absorption phonique des isolants pour réduire la résonance des bruits par l’ossature de l’escalier et le volume sous l’escalier. La première est de contrôler les impacts de pieds sur les marches lors de la montée. Les nuisances sonores, nous l’avons vu, se créent par impact – résonance sur les matériaux. La seconde est le remplacement des marches ou de l’escalier.

Les solutions acoustiques de soniflex permettent d'optimiser de manière ciblée l'insonorisation des pièce d'habitation et des cages d'escalier. Absorbeurs acoustiques pour murs & plafonds – Nos absorbeurs muraux soni ELEMENT ou nos plaques acoustiques soni COLOR réduisent les réflexions sonores gênantes et la réverbération. Tableaux & éléments acoustiques – Des absorbeurs acoustiques fonctionnels au design attrayant, par exemple soni HEXAGON et soni PICTURE, qui mettent en valeur visuellement les pièces d'habitation & les cages d'escalier. Isolation acoustique des portes – Mit soni PORTA, la porte devient une barrière acoustique et empêche le flux de bruit indésirable entre les pièces. Surtout dans les espaces de vie ouverts, les pièces hautes ou les bâtiments anciens avec une construction en dur, une réduction ciblée du bruit par des panneaux acoustiques ou des éléments de plafond peut rapidement apporter une amélioration sensible. Nos produits d'insonorisation soniflex sont faciles à monter et offrent une solution durable contre les réverbérations gênantes et la transmission du bruit.

Considérer l’isolation acoustique des cages d’escalier dès la conception des copropriétés permet en effet d’éviter des problèmes et des inconvénients lorsque les bâtiments abritent de nombreuses réalités différentes avec des habitudes différentes. SYLCER, notre solution dédiée à l’atténuation du bruit causé par le piétinement dans les escaliers, a été spécialement conçue pour être facilement installée sous les sols en céramique, normalement installés dans les cages des copropriétés. Cet isolant en rouleau a été conçu pour garantir une absorption efficace du bruit provenant du va-et-vient continu dans les escaliers et, par conséquent, pour permettre une réduction significative de la gênante propagation sonore générée par la structure en béton typique des escaliers. Nos isolants acoustiques Mustwall B sont constitués de panneaux couplés composés de granulés de caoutchouc SBR et placoplâtre. Cette composition leur confère une significative capacité de réduction du bruit provoqué par la voix des personnes, ce qui en fait des alliés idéaux dans l’isolation acoustique des cages d’escalier, contribuant à créer un environnement plus calme et plus confortable pour tous les résidents de la copropriété. Nos panneaux isolants Mustwall B possèdent également une capacité exceptionnelle de réduction du bruit généré par les vibrations provenant de l’activité constante de montée et de descente des ascenseurs. Cette caractéristique en fait le choix optimal pour améliorer l’isolation acoustique des murs des cages d’ascenseur, contribuant ainsi de manière significative au bien-être acoustique des résidents de la copropriété.

Vous devez recourir à une insonorisation encore appelée par isolation pour ne plus entendre de bruit ou d’écho au niveau de votre cage d’escalier. Utiliser la technique des salles de cinéma, vous pouvez installer des cadres en forme de cadre que l’on recouvre de tissu. Ces cadres ont pour but d’éviter le rebondissement du son grâce au tissu qui est capable d’absorber toute la sonorisation. Alors, pourquoi ne pas adopter cette technique au niveau de votre cage d’escalier en l’habillant avec des cadres en tissu pour limiter l’écho considérablement. Un tapis peut servir de chemin d’escalier afin de faire cesser l’écho. Cependant, ce tapis ne sera pas suffisant à lui seul si votre escalier est en bois parce qu’il y aura un bruit qui va se percevoir d’un côté à l’autre. Il vous faudra donc ajouter des éléments qui permettent d’amortir ce bruit en utilisant des cadres en tissu pour éliminer totally le bruit. Vous pouvez aussi utiliser de la mousse acoustique au niveau de vos marches d’escalier pour empêcher l’écho des pas, cette solution donne un résultat surprenant en réduisant l’écho au niveau de la cage d’escalier. La laine minérale est également un bon isolant, c’est un véritable absorbant acoustique qui lutte efficacement contre la réverbération et retries ces bruits.
