[Greenbuilding] Mushroom insulation ~ SIP

[Dan Barry]

How would these compare in insulation value?
SIPs made with styro and other foams must have a fire rating, is this the
same?
How could I "heat" the walls to stabilize mushrooms, maybe just solar heat
the building without much insulation.  It might not be as absurd as it
seems.

I really just need it for central Texas dry heat.
