we are trying to install a fisher baby bear. We are wondering if there's a manufacturer of prefabricated stove board that we can simply buy and lay on the plywood floor instead of building a hearth. It would also be nice to simply hang stove board on the wall too. It seems if the stove board is made of a 1" piece of micore, sandwhiched between a sturdier material then that would have the r value of 2.2 and be enough to protect the plywood floor from the heat of the stove. My husband would like to do a quick hearth thats removeable as we have to move into this place in 2 weeks and will probably only have the stove in there for one winter before moving it else where. It would be nice to take the hearth with us. HyC makes a stove board that amazon says micore mineral board core wrapped with 30 guage steel. I can't however find the r value for the stove board. Are there stove boards with an r value of 2? Right now we have a bare plywood floor. our original plan was to screw a micore base directly under the stove about 16"x32". R value 1.1 for a 1/2" piece. Then two 1/2" layers hardie backer board 18" to the left and right sides and in front of stove. Behind the stove 12" of two layers of hardie backer board 1" total thickness. With one 1/2" hardie board under stove ontop of micore. Then some .50 cent tile cemented ontop of the hardie board. Behind the stove we are going through the wall and were told we could use tripple wall piping coming directly out of the back of the stove, through the wall (we bought a duravent through the wall kit to use) and all the way up to the chimney to reduce clearance between back of stove and wall. The clearance between the back of the stove and the 2x4 stud is 12inches. Currently there's nothing on the wall yet, just bare studs and no insulation. Our plan was to hang gold bond fire resistant drywall. then 1 inch copper spacers attached to a piece of Micore that's about 18" wide and extends the height of the stove. We were told by installing a heat shield on the wall with 1 inch spacers it would reduce clearance requirements to 12 inches from back of stove as long as all piping is tripple wall. My husband also wants to cut a piece of micore to fit the back and wrap a couple of inches around sides of stove to act as an additional heat shield but we're not sure how to attach that to the stove. We've seen a piece of steel attached to the back of a friends stove with an air gap between the stove and steel and it has provided extra heat protection for his wall which is fireresistant drywall. Hubbie was going to try and construct a similar type hanging heat shield from the micore.
