Homestead heritage – Hearth Pad Construction

[chad101]

After collaborating w/ allot of people on this forum and talking to customer service @ Woodstock. I ended up buying a heritage stove.

I bought a 4'x 4' "stove pad" ($400). But, the dealer will not order it until Monday.

I'm thinking about building my own hearth pad to save money. I have a 40 (4"x 8"x 16") concrete blocks. This is more than enough for a 5'x 5' hearth pad. Menards has a sale on natural stone tile (granite & marble tiles). I was thinking about laying tile over the blocks and wonder if this combination would be sufficient in R value.

I doubt it. Concrete doesn't have much R-value at all and the heritage has a high R-value requirement. The owner's manual will give you the R-value of some common building materials and if you're lucky, you can find some micore which could be included in your pad and eliminate the need for other special R-value consideration. The durock and tile will finish the job in that case. I couldn't fine micore so I used the "dead air apce" as specified in the owner's manual to provide the bulk of the required R-value.
