Abstract

A decorated flooring member constructed using the DPL process and comprises a high density fiberboard (“HDF”) core and a wear layer that has an EPLF rating of AC5. In operation, the flooring member of the present invention will exhibit similar characteristics to an HPL constructed flooring member while retaining the cost benefits of a DPL constructed flooring member.
