<p>Flexible base web of a construction covering, such as floor or wall covering or a roofing comprises a main layer (1) extending over the greatest part of the thickness of the web. The main layer is constituted of a non-woven mineral fibre mat containing predominantly discontinuous mineral fibres, such as rock wool or slag wool or glass wool fibres which are bonded to each other mechanically. A thin layer (2) containing thermally bondable fibres (1) is interposed between the main layer (1) and a coating layer (3) of polymeric synthetic material.</p> |
