    Thank you, though my son deserves at least as much credit. Without his carpentry and mudding and being too dense to refuse to climb the scaffolding to build the chimney, I'd still be putting it together!

    Thanks. That looks great. Right now, we're leaning towards 1x6 boards as trim, with a little strip of moulding (door stop material?) that goes over the edge of the slate tiles.

    Wytheville I have worked with a bunch of folks from there. This world just keeps getting smaller and smaller.

    Mineral Fiber Board ( Micore 160 ) 1/2" 1.270
    Ceramic Board ( Rescor 360 )
    1/2" 1.110
    Ceramic Board
    ( Fiberfrax Duraboard LD ) 1/2" 1.100
    Mineral Fiber Board ( Micore 300 )
    1/2" 1.030

    Does anyone have any sources for the products listed above? I have looked at premade stove boards and they are smaller than I need, have an R value of 1.x and are not that cheap or attractive.

    I found the micore 300 at Menards; anyone else has any sources for any of the products listed above?

    I got the durock for my hearth install from lowes. They didn't have a board in the thickness that I wanted/needed so I did a double layer which worked out just fine.

    Yes, I have a Lowe's that I can visit for the durock but need a source for the insulating materials; Lowe's does not carry any of the products listed above. Trying to see if anyone has a cheaper source. Money is tight and every penny counts.

    Right where I want to be.
    I've heard the Micore is pretty spendy, but it's your best option if it's all you can get, and you want/need to keep the hearth low.
    I had no idea Menards had it.
    ETA: 2 layers of Micore, then one Durock and you've exceeded the R requirement.
    You'll likely need most of a full sheet of the Micore, if not all to make the hearth the required size.
    If you plan to tile, that adds almost nothing to the value. Tile can be had VERY inexpensively.

    Yes, I have seen tiles on clearance at Lowe's and thinking that is the cheapest for the final surface. The stove specs says R2 below the stove to combustibles and I would think that includes any framing materials for the hearth. Therefore, that would mean framing out in steel studs and having enough air space. I think the easiest way to build the hearth is two layers of the micore, then the durock, then whatever finished product. I have looked at premade floor protectors and they appear to only come in R1; so two would be needed. Plus they are not cheap either to get one in the correct size; I have seen prices of around $400.00 and up.

    I have not been able to find a retail location for any of the other products.

    Of course I don't actually have a stove yet :-(.

    You don't need anything under the Micore for more insulative purposes. If you want to raise the stove some, that's where the framing comes in.
    A bunch of us on here have raised hearths. Mine's about a foot high, because I've got bad knees, and I got real tired of kneeling to start/tend a fire. My knees thank me every day.

    Could you stack four or five layers of 1/2" Durock? That'd get you there and still be pretty low.

    How much is Durock nowadays? Compare the price of 5-6 3'x5' pieces of Durock to the Micore.
    I bet the price is fairly close.

    I recently bought it at $10 or $11 a sheet at Home Depot. Cheap comparatively.

    IIRC; and don't hold me to this, but I think the OUTFIT that I bought my "micore" thru online was out of Canada. Twas probably more $$$ than if I could've found a USA source, but it wasn't outrageous.

    Well, she's gonna' need a sheet or 2 of the Durock plus the Micore, OR just 5-6 sheets of Durock. Hmmm.
    What's the R-value of the Next Gen Durock? I thought I heard .39 somewhere.

    Micore is the way to go IMHO...................for the simple fact that how are you gonna fasten 4-6+ layers of durock to a solid foundation in order to meet the R2 value the 13NC requires. Just saying!!

    The 13NC is "A LITTLE BIG STOVE"!!!! It'll heat my 1200ft poorly insulated and laid out ranch house without a problem in temps down to around 0*F. She'll struggle a bit in temps lower than that............................but it's due mainly to my house lay out and firebox size.
