Does any one know where or if Alaska Stoves specifies and R-Value for the hearth pad? I've looked all over and can't seem to find a specification. I don't find anything in the manual or on the stove data plate. I have the channing 2. Not having a R-value is making it a bit difficult to design a hearth pad that will meet requirements and yet be pleasing to my wife :-)

Thank you.

Regards,
Ed

Hi Fred,
I'll be building my own. Just trying to figure out the required R-Value so that I can calculate what materials and thicknesses to use.

For example, how many sheets of concrete board would be sufficient? Would a piece of 24 GA sheet metal be needed also? Etc.

Ed

Did you get your hearth built?
I switched from wood to coal last year. My wood stove was small so I had built a platform for it to sit on which was about 1 foot tall. 2x12 frame. And I had added 2 sheets of cement backer board, a coat of cement and added 1/4" tile. It worked good. I thought the floor was getting a bit warmer than I liked so I put a lowes fire board under the stove. It worked just fine. Now that I had changed to coal the foot tall base was just too tall to climb up every time I had to add coal. I removed that base and made a new one. I wanted a change - a new look and I didn't want the black lowes stove board sitting on top. So.. I built a 2 1/2 tall frame. Lined the bottom with stove board then poured 2" of concrete on top. Leveled it out and added solid clay bricks to make a solid base for the stove to sit on. It's about 5" tall and the heat from the stove warming the base doesn't concern me anymore.
