Mike, I'm sure that you write the above with the best intentions, but I certainly hope that anyone who is reading this list does not invest significant financial resources or chunks of time if he is building in accordance with the belief which you have stated above. Cob has nifty properties, but it's no more insulative than any other dense clay. There's nowhere near enough straw in it to provide significant insulation. The clay is just clay, and will insulate as well as any dry dirt, which isn't a lot. Cob works in certain situations (previously discussed) because it has a lot of mass. It also lends itself to low-tech, rounded, expressive architecture. In no way does its value as insulation come anywhere near modern-day insulation. I invite any who has actually lived in a cob building (and understands the difference between insulation and thermal mass) to tell me differently, and why. -Speireag. 0>>>>>>(--------------------- Speireag Alden, aka Joshua Macdonald Alden Joshua.M.Alden.91 at alum.dartmouth.org Usually found somewhere in the wilds of New Hampshire.
