摘要： A floor panel and a floating floor system incorporating the floor panel include a floor panel having a top layer and a bottom layer. The top layer has a top surface and a bottom surface. The top surface has a visible decorative pattern. The bottom layer has a top surface and a bottom surface. The top surface of the bottom layer is adhered to the bottom surface of the top layer such that the bottom layer is offset from the top layer in a direction of length and width and a marginal end portion of the top surface of the bottom layer and a marginal end portion of the bottom surface of the top layer is exposed. At least one of the marginal end portions has an adhesive, and a ratio of a thickness of the top layer to a thickness of the bottom layer is about 5 or greater.
