[Cob] Cob R Value

Hi Cobbers,

We have an home energy consultant reviewing our cob house plans. She wants to know the R value of cob. I heard around 0.7/inch, but only anecdotally. Does anyone know of any tests or work done to come up with an accurate range for R? To contrast the consultant had heard the value was closer to R1 for a 24" wall.

Thanks,

Steve
