Last time I build a permanent hearth for my Englander 30 -NC. We have moved to a new house and I brought the stove. This time I am just going to build a hearth pad. My problem is the 30-NC takes an R factor of 1.5. I don't want something over 2 inches thick and would prefer thinner. Now in all practicality I ran my 30 all winter in the other house and the hearth never got hot. It was pleasantly warm but never got anywhere near what I would worry about. I had the leg set up. Now I did get quite a bit of heat out the front glass but that was not even on the hearth. The hot spot was in front a few feet on the carpet. However, I want to stay within the manufacturer's requirements. I would like to get micore or a ceramic board, but I can't find any local suppliers. I live in the Springfield, MO area. Any suggestions on where to get the stuff reasonably or a hearth set up that would work. I don't really care of the raised hearths. Thanks for the help.
