Cob: RE: RE: Insulation - vermiculite

[Grace Benjamin]

Hello All

Vermiculite is the fluffy, white, lightweight material often found in 
commercial potting mixes.  You can buy it seperately, and it has the texture 
and consistency of polystyrene (styrofoam) "popcorn" just much, much smaller 
pieces.  I assume Lyle's intent is to incorporate it evenly into the cob 
mix, just like it is mixed into potting soil- and for very much the same 
reason- to keep air spaces in the mix.

While a terrific idea, my only concern is denigrating the stability of the 
wall as a whole; has anyone tried this?

Grace

You know, John, I was just going to ask the same thing...

Lyle or Holly,

Please clue the rest of us (or at least John and I, I guess) in to the magic
of vermiculite...  Is this some miracle additive to insulate with?
