A panel-like/sheet-like finishing element (11) for covering floors and walls, for example in the renovation of old buildings, is provided with heat-insulating and sound-absorbing properties if its interior (15) is provided, between outer covering layers (12, 13), with channel-forming undulating supp
A panel-like/sheet-like finishing element (11) for covering floors and walls, for example in the renovation of old buildings, is provided with heat-insulating and sound-absorbing properties if its interior (15) is provided, between outer covering layers (12, 13), with channel-forming undulating supporting structures (16) filled with high-density coarse granules (21). The supporting structures (16) are connected to the covering layers (12, 13) along the vertex lines (17) so as to provide wet-strength action, and the interior (15), between these covering layers, is sealed by enclosing edging strips (19) to provide wet-strength action, with the simultaneous inclusion of moisture-tight, but vapour-permeable, supporting layers (20) on covering layers (12, 13). If this finishing element (11) is mounted vertically, the granule-filled channels (14) run horizontally.

1. Sheet-like finishing element comprising, in its interior between upper and lower cover layers or separating layers, supporting structures which undulate in cross-section in a curved or angular manner and define channels filled with granular material, wherein the upper and lower cover layers or separating layers and the supporting structures have highly-filled tough pulp polymer comprising natural gelatine or starch adhesive or aqueous silica solutions or even synthetic resin as a binding agent, andwherein the finishing element is fully wet-strength sealed by means of edging strips. 2. Finishing element according to claim 1, characterised in that, in cross-section, the supporting structures have an extension which either meanders in the shape of a hollow cuboid or is triangular or sinusoidal. 3. Finishing element according to claim 1, characterised in that channels of the supporting structures which extend orthogonally to the cover- and separating layers are closed by the cover layers and the separating layers. 4. Finishing element according to claim 1, characterised in that its interior has upright hollow members as supporting structures. 5. Finishing element according to claim 1, characterised in that the supporting structures are connected cohesively to the cover layer. 6. Finishing element according to claim 1, characterised in that at least one of the cover- or separating layers is fitted with a moisture-resistant yet vapour-permeable protective layer. 7. Finishing element according to claim 1, characterised in that its cover- and separating layers and/or its supporting structures have long-fibred amorphous natural or artificial mineral wool. 8. Finishing element according to claim 1, characterised in that the granular material in the channels is burned silica sand. 9. Finishing element according to claim 4, characterised in that the upright hollow members are upright honeycomb structures of either triangular or hexagonal cross-section. 10. Finishing element according to claim 5, characterised in that the supporting structures are wet-strength bonded to the cover layers. 11. Finishing element according to claim 5, characterized in that the supporting structures are connected cohesively to the cover layers and the separating layer. 12. Finishing element according to claim 11, characterised in that the supporting structures are wet-strength bonded to the cover layers and the separating layer.
