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 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.
Claims16
A floor panel being rectangular and oblong and comprising a substrate and a top layer provided on said substrate;
- wherein said top layer is at least composed of a print and a transparent thermoplastic layer situated above said print, the top layer extending over the substrate along a top planar surface of the floor panel parallel to a length of the floor panel,
- wherein said transparent thermoplastic layer has a thickness of less than 1 millimeter, the transparent thermoplastic layer is based on a material selected from the group consisting of polyvinyl chloride, polyurethane and polypropylene, and the top layer further comprising a lacquer layer located above and separate from the transparent thermoplastic layer and selected from the group consisting of a UV-hardening lacquer layer, an electron beam-hardening lacquer layer and a polyurethane lacquer layer, and
- wherein said floor panel at one or more edges comprises a chamfer defined as extending obliquely relative to the top planar surface of the floor panel at said one or more edges, wherein said lacquer layer is omitted on a top surface of said chamfer and terminates at the chamfer from extending along the top planar surface of the panel as part of the top layer, wherein two of said floor panels arranged in a coupled condition have a lacquer-free V-groove formed by corresponding parts of said chamfer, and wherein said lacquer-free V-groove defines a width larger than the thickness of the transparent thermoplastic layer, wherein a portion of the top layer beneath the lacquer-free V-groove of two of said floor panels in the coupled condition contact one another.
