In order to soundproof a tiling (2), an intermediate layer is interposed between the latter and its rigid support (1), which layer consists essentially of a prefabricated thin board adhered along its two faces respectively against the upper face of the rigid support and against the lower face of the tiling, the said board itself comprising two elementary layers adhered against each other, namely a lower sheet (5) consisting of fibres embedded in bitumen and an upper septum (6) of bitumen containing no fibrous elements. <IMAGE> |
