Hi Charmain,

Do you know what amount of R you get with a light straw clay wall? Have you
built a regular cob wall then, with forms, done a light clay wall on the
interior from floor to ceiling? How did you design the forms for all the
curves? How did the light clay stay up on the cob walls? any separation?
