You would then build forms on the inside between studs and fill the gap with the slip-straw, tamping it down as you go. You can finish it with a mud plaster. You could also use cob where you wanted a more organic aesthetic. I have worked with this method and if you go this route make sure you get it ever so lightly coated so that you can gain a higher Rvalue as normal straw clay won't give you more that an R1 per inch and you don't want to go over 12". I still find strawbale to much faster and easier and better insulation value. I prefer to think of straw clay for interior walls.

Is this a stupid idea? The barn is somewhat old, but the structural beams appear to be in good shape. Would there be a problem with placing the cob right next to the wood? Maybe cob is not the way to go, I just want to use natural materials. Some other method may be more insulative, as well. I would appreciate any ideas. thx, Zon from Kansas Chris, Not to discourage you from cob, but you might consider slip-straw if you already have existing walls. I am planning to do this to an existing barn. Slip-straw is loose straw coated in a clay slip.
