I made a thread the other day about closing in my fireplace with pics and a member here called coog brought it to my attention that I had insufficient top on my hearth. This site has been a life saver for me on this project. Anyway I have been looking for some Micore 300 fiber board and cant find it anyplace around here.I even had out tool purchaser at the machine shop where I work check on it.He found one place that had some. $48 for a sheet which is great but they want $238 to ship it which I think is nuts. I called a fireplace store about 35 miles from me and he doesn't carry it but he does carry Hearth and home HX3..He says they usually only put one layer down but my manual calls for two layers of 1/2" Micore 300.My manual says 1" of hearth and home HX4 is fine. They carry HX3,Anyone know what the difference is?
