A site visitor just turned me on to a potential hearth material called Rescor (view at http://www.m-r-c.co.il/Media/Uploads/360SPEC.pdf ).
My questions: would the values listed under "Thermal Conductivity (BTU-in. /Hr. Ft2 ºF)" be the R-values per inch of the variations of this material listed? And if so, what temperature would be applicable? It seems to me a hearth will never get hotter than 500f, so I would guess that would be the line to use.
