A sheet adapted for installation as substructure to a non-anchored floor comprises a laminate (1) of a moistureproof, shock absorbing and porous layer (2), a substantially gasproof layer (3) and a shock absorbing fibrous layer (4). The laminate is manufactured of a porous polymer material, a web of a gasproof foil and a web of fibre material. The webs are seamed together along the edges, where respective zones of the foil are in face to face contact. In this way, it is possible to obtain a barrier layer which is gasproof, impermeable to rising moisture and which has good properties regarding sound attenuation, shock absorption, heat insulation, and ease of installation. |
