All the heat resistant rock is there at the pro Services area Andy heat resistant sheet is also there at the pro Services area you'll need to put that up first to keep the heat off of the walls and then believe it is $20 a sheet The Rock varies in price is just all depending on the style and color that you want it can go from $0.62 a piece all the way up to a dollar 5 apiece the tile is in the back of the store and it goes from $0.35 a sheet piece 2 $2.50 at sheet or you can just buy it by the piece you don't have to buy it in the sheets and you can also install this with liquid nails which is in the paint area and it can be anywhere from $2.20 to be to $4 a tube
I would probably go to Lowe's and to that stone area they have a firewall that you can put up that's pretty simple just have to ask the questions that's about all I can tell you sorry or try Home Depot
