R Value of Marble?

[Bron]

Hey all ! Still looking for micore in upstate ny. i hear there is some in rochester. It's a short drive and is probably what i will do .Wanted to ask though ! my brother has some insanely large slabs of marble varying in thickness from 1 to 2 inches in his garage.. The stuff was torn out of his house by previous owners. At one time there was a large fireplace in there, and this marble was all over the place. Is a shame but S*%t happens right? I Bet it was beautiful.. Anyways i was trying to figure out R value of this stuff . Anyone have any clue?

In general....(not with respect to the site in the link)...I wouldn't place a lot of stock in what you read on the internet. If the answer is important, check the information with other sources.

Having said that just about any "rock" is going to have an Rvalue of less than one.

You might also want to check the site you're currently on (Hearth.com). There's a list of common materials and their R-values which I used last year to find the R-value of slate. It may be in the HearthWiki under "hearths". Anyway, Meister is correct. Most stone has a very low R-value.
