Does anyone know of a source,to get a metal clad stove board.I see them and have one that is 36"x52".But my new old stove requires a 52"x44".I have not been able to source one.I really don"t want to lay tile if I can help it. And I have saw pre-fabbed tile hearth"s but they are expensive. If any info on the stove board please let me know.
