We used a 6" layer of a cob/pumice mixture underneath our radiant adobe
floor. Pretty hard to put an R value to it but it seems to be working well.
Pumice has to be mined so it is not completely green. Perlite would work but
it is also mined and then fired in a kiln. Both seem(completely subjective)
like a better alternative to XPS. EPS is often made from recycled material -
can be a little greener. Our locale is very dry and the soil drains well so
I do not worry about the straw in the mixture rotting.
