Insulating outside of block home?
I am building a earth-sheltered passive block home. I want to insulate it all from the outside. I have been trying to get Roxul Drainboard in 3.5 inches but cannot afford a whole truckload to do a small home. So I'm thinking of using 4 inches of XPS foam under slab and all walls.
Any suggestions for water proofing exterior of block and fastening XPS to all the walls?
