Has anyone looked into this as a hearth insulation?
It is a mineral wool insulation block. I found this data sheet
http://www.dispro.com/upload/D1178.pdf
The rep at the local refractory supply mentioned it as a possible alternative to ceramic fiber board (which is what I am assuming SuperIsol is, I am having a bit of a tough time finding specs on it.)
For refractory cement he recommended Sparcast 30L, its a 3,000?F conventional castable that comes in 50# bags. It seems like overkill, but it is much cheeper than HeatStop from the fireplace supplier.
I am learning way more than I thought I needed to know about refractory products.
Thanks all for your input.
