My Jotul tdic came with a "hearth pad" i dont know if the owner built it, but i can tell you that it has at least a 1 1/2 inch thick piece of plywwood covered with cement board, then covered with tile. It must be around 3-4 inches thick. It is heavy as all h3ll too! My wife wants to build our own instead of using this one, which is ok with me! My question is that i cannot find what R value my stove requires underneath it during operation, and how to calculate the r value of a 1/4 inch piece of plywood and standard cement board (durorock?) and tile would be. I want it to be thin, but safe.
I have all the tools to build it, just dont know what the minimum thickness can be and the best materials to use
