Abstract
A floor panel has a rectangular and oblong shape, and includes a substrate and a top layer provided on the substrate and forming a decorative side of the floor panel. The top layer is composed of a print provided on a carrier sheet and a transparent thermoplastic layer situated above the print. The substrate has a thickness from 2 to 10 millimeters and forms at least half of the thickness of the floor panel. The substrate is a polyurethane-based substrate, and the transparent thermoplastic layer is polyurethane-based. The floor panel has a length of more than 1.1 meters and has a plurality of reinforcing layers situated outside the center line of the substrate. A reinforcing layer may be provided in combination with the substrate and the top layer.
Claims13
A floor panel, wherein said floor panel is rectangular and comprises a first and a second pair of opposite edges, and an upper surface, wherein the upper surface consists of a global decorative side and at least a chamfer on one of the first and second pair of opposite edges;
- wherein said floor panel comprises a substrate and a top layer provided on said substrate;
- said top layer forming at least said global decorative side of said floor panel and being composed at least of a synthetic material film carrying a print, a transparent thermoplastic layer situated above said print and a lacquer layer as a topmost layer in said top layer, wherein the synthetic material film is a PVC-based film, wherein a common thickness composing the synthetic material film, said print, said transparent thermoplastic layer and said lacquer layer is between 0.5 and 2 millimeters;
- said substrate being a board material having a density of more than 650 kilograms per cubic meter and forming at least one half of a thickness of said floor panel;
- said substrate being a vinyl-containing and/or polyethylene-containing substrate;
- wherein said print, at said global decorative side, has a global level within the top layer and extends downward at the chamfer, wherein said chamfer is straight or curved, and is adjacent to said global decorative side, said chamfer extending below the global level of the print;
- wherein said print and said lacquer layer extend uninterruptedly from on the global decorative side of the floor panel over an entirety of said chamfer;
- wherein said top layer, including the synthetic material film, the print, the transparent thermoplastic layer and the lacquer layer, extends over the chamfer and comprises a pressed-down material part at said chamfer and said substrate at a location of said chamfer comprises a locally compressed portion.
A floor panel, wherein said floor panel is rectangular and comprises a first and a second pair of opposite edges, and an upper surface, wherein the upper surface consists of a global decorative side and at least a chamfer on one of the first and second pair of opposite edges;
- wherein said floor panel comprises a substrate and a top layer provided on said substrate;
- said top layer forming at least said global decorative side of said floor panel and being composed at least of a synthetic material film carrying a print, a transparent thermoplastic layer situated above said print and a lacquer layer as a topmost layer in said top layer, wherein the synthetic material film is a PU-based or PP-based film, wherein a common thickness composing the synthetic material film, said print, said transparent thermoplastic layer and said lacquer layer is between 0.5 and 2 millimeters;
- said substrate being a board material having a density of more than 650 kilograms per cubic meter and forming at least one half of a thickness of said floor panel;
- said substrate being a polypropylene-containing and/or polyethylene-containing substrate;
- wherein said print, at said global decorative side, has a global level within the top layer and extends downward at the chamfer, wherein said chamfer is straight or curved, and is adjacent to said global decorative side, said chamfer extending below the global level of the print;
- wherein said print and said lacquer layer extend uninterruptedly from on the global decorative side of the floor panel over an entirety of said chamfer;
- wherein said top layer, including the synthetic material film, the print, the transparent thermoplastic layer and the lacquer layer, extends over the chamfer and comprises a pressed-down material part at said chamfer and said substrate at a location of said chamfer comprises a locally compressed portion.
