A substrate for use in a flooring system which has a subfloor and a decorative upper layer. The substrate is made in a continuous sheet which has a bottom surface, a top surface, side surfaces and end surfaces. The top surface and the oppositely facing bottom surface are essentially parallel to each other and are spaced apart by the thickness of the substrate. Voids are provided in the substrate, the voids are provided between particles of rubber or other similar material. When the substrate is positioned between the subfloor and the decorative top layer, the particles of rubber provide the strength required to prevent deformation of the substrate in the direction of the thickness and the voids contribute to the sound dampening characteristics required to provide decibel reduction across the thickness of the substrate.

Un substrat à utiliser dans un système de parquet comportant un plancher brut et une couche supérieure décorative. Le substrat se compose d'une feuille continue ayant une surface inférieure, une surface supérieure, des surfaces latérales et des surfaces d'extrémité. La surface supérieure et la surface inférieure lui faisant face à l'opposé sont essentiellement parallèles l'une à l'autre, et elles sont séparées par l'épaisseur du substrat. Des vides sont fournis dans le substrat. Ces vides sont procurés entre les particules de caoutchouc ou d'autres matériaux similaires. Lorsque le substrat est positionné entre le plancher brut et la couche supérieure décorative, les particules de caoutchouc fournissent la force nécessaire en vue d'empêcher la déformation du substrat dans le sens de l'épaisseur, et les vides contribuent aux caractéristiques d'insonorisation requises afin de procurer une réduction des décibels à travers l'épaisseur du substrat.
