Abstract
A floor, wall or ceiling panel comprises a core and a decorative top layer provided on the core. The core comprises a magnesium oxide-based board material, and wherein the aforementioned panel, on at least two opposite edges, is provided with coupling means allowing that two of such panels can be interlocked at the respective edges.
Claims23
A panel comprising a core and a decorative top layer provided thereon;
- wherein the core comprises a magnesium oxide-based board material forming at least half of a thickness of the panel, and wherein the panel, on at least two opposite edges, is provided with coupling means arranged for two of such panels to be interlocked at the respective edges;
- wherein the coupling means is arranged for locking in a horizontal direction and a vertical direction, the coupling means are formed as a tongue and groove connection such that the groove is bordered by an upper lip and a lower lip, the lower lip extending in the horizontal direction beyond the upper lip;
- wherein a first reinforcement layer is located along a first side of a thickness of the core and a second reinforcement layer is located along a second side of a thickness the core, the thickness of the core being defined between the first and second reinforcement layers;
- wherein the first reinforcement layer, on the first side of the thickness of the core is flanked by a second layer of the magnesium oxide-based board material;
- wherein the second layer of magnesium oxide-based board material comprises less fillers than at a central portion or central layer of the aforementioned magnesium oxide-based board material.
