ABSTRACT:
This invention relates to mineral fiberboard products which are embossed to provide a decorative surface. In the invention herein a layered structure is formed before the embossing process that consists of the currently used mineral fiberboard on the bottom with an additional layer of a granulated fines material on the board surface. When embossed using the current process, the resulting composite board provides higher fidelity images than the unlayered embossed board.
