Untitled Document Earthbag Building What is Earthbag Building? Well, plainly enough, it’s a method of building using bags filled with earth. This newly released…

“Earth makes for excellent thermal mass, but has little value as an insulator, except that because the walls are generally quite thick, and it takes many hours for atmospheric temperatures to approach the interior portions of the wall. For this reason it would be best to provide some insulation in the wall system where extremes of temperature are found.”

actually, earth is a terribly inefficient insulator. it would take several feet of earth to measure up to a few inches of foam. a cheap, superb insulator would be strawbale because of it’s many air pockets (like foam). the earthbag building technique is great for hot, treeless areas, but in a temperate climate a log cabin would be more efficient.
