Interesting, all of the info I have read on using a layer of insulation on any thermal mass construction was to have the insulation layer on the outside of the mass to help regulate it from outside temps. Also, Owen Geiger makes note of a layer of insulation on the outside of the earthbag structure. Interesting Idea to think on. Plan on Building a earth bag home within the next year or starting to break ground.

Hello! My wife and I had the opportunity to visit the Majors earth bag home on two occasions, so yes you can use crushed limestone in the bags and no you do not have to add clay if using this fill material. The crushed limestone felt to me like a stone wall, extremely solid.
