A panel, in particular a floor, ceiling, or wall panel, of a planar design having a top side, a bottom side and multiple side edges, which panel has a laminated structure of layers that are adhered to each other. The layers extend parallel to the plane of the panel, and include a core layer having a lower side and an upper side, and a top layer which is provided on the upper side of the core layer either directly or indirectly. At least two layers of the panel, in particular the top layer and the core layer, are directly or indirectly adhered to each other by an intermediate adhesive layer. The intermediate adhesive layer is composed of adjacent intermediate zones which include non-adhesive intermediate zones and adhesive intermediate zones, which intermediate adhesive layer establishes an adhesive strength between the two layers, such that a durable adhesion between the two layers is obtained, and a clean delamination of the two layers is allowed for when the two layers are subjected to a sufficient delamination force.

A decorative panel including a core provided with an upper side and a lower side, a decorative top structure affixed, either directly or indirectly, on the upper side of the core, a first panel edge comprising a first coupling profile, and a second panel edge comprising a second coupling profile designed to interlockingly engage with the first coupling profile of an adjacent panel, both in a horizontal direction and in a vertical direction. The core comprises at least one wool layer at least partially formed by man-made vitreous fibres bonded together by at least one cured thermoset polymeric binder material. The decorative top structure comprises at least one ceramic layer and/or glaze layer, wherein the decorative top structure is adhered onto the core with a waterproof adhesive.
