ABSTRACT OF THE DISCLOSURE A flat composite body (1) comprising a top layer (2) containing fibers or filaments and a support layer (3), which is at least passively needle-bondable, with the two layers (2, 3) including between them an internal layer of granular particles (6), for example sand and being needle bonded to each other through the internal layer. A composite body (1) of this configuration may be used as a self laying carpet or carpet tiles. By means of sand additions, an especially favorable sound attenutation is obtained. The high level capacity and poor thermal conductivity provide positive behavior in a fire.
