[Cob] Coblist Digest, Vol 9, Issue 98

[Damon Howell]

That's funny. It does say in the book that it is the discretion of  
the official to allow the use of non-approved materials, and he's  
allowed to carry out what tests he sees fit in order to approve it.  
So it's not exactly the code that's bias, but the officials who want  
their job to be as easy as possible. That's perhaps why they lean  
towards pre-approved building materials. But occasionally one comes  
across an official who's eager to learn cob. The insulation value is  
a sharp jab to cob because no matter what it will never have a high R- 
value. Thermal mass isn't considered in code, which is silly to say  
the least.

We all know that to put insulation into the cob walls ruins it's  
ability to breath properly and messes with the thermal mass so until  
someone invests the money to prove thermal mass to the Building Code
