Floor panel
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 millimeter 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.
