Floor panel and methods for manufacturing floor panels

A floor panel having a rectangular shape and at least two opposite edges, the floor panel comprising:

• a substrate, wherein the substrate includes a PVC board having an average density of more than 300 kilograms per cubic meter, and wherein the PVC board includes filler materials selected from the group consisting of chalk, wood fiber, and sand;
• and
• a top layer provided on the substrate, wherein the top layer is fabricated from a vinyl material, and includes a motif formed by a print, and a transparent or translucent layer situated above the motif;
• wherein at least two separate layers are embedded in the PVC board, the at least two separate layers increasing the bending stiffness of the PVC board, the at least two separate layers being situated at a distance from the center of the PVC board, a first one of the at least two separate layers being situated between the center of the PVC board and the top layer, a second one of the at least two separate layers being situated between the center and a side of the PVC board opposite the top layer, the at least two separate layers being selected from the group consisting of a glass fiber cloth and a glass fiber fabric;
• and
• coupling means for allowing the floor panel to become locked to an adjacent floor panel, wherein the coupling means is located at the at least two opposite edges of the floor panel, and wherein the coupling means is formed out of the material of the PVC board and the top layer.
