[Cob] Double walls

[Amanda Peck]

If you have access to Rob Roy's books on cordwood masonry--especially the 
latest--check it out--he likes to use a double (all earthen, sometimes) wall 
with insulation inside.  If cordwood masonry works, since there are cob 
houses hundreds of years old in England--if not Denmark--I'd guess you are 
fine with wood in cob.  My copy's loaned out, but he should tell you how to 
put a plate on the top.

anchor's the right word.

Does anyone have any experience with double cob walls with insulation in 
between? We live in Denmark where the climate is rather cool, and massive 
cob walls will let out too much heat in the winter. So we're thinking about 
making the outside walls double, 10-15 inches each (the roof will carry 
itself), with recycled paper-insulation in the middle.

We suppose that we will have to use something to anchor (is that the right 
word in english?) the two wall-parts together. Of course we can buy some 
plastic hooks, but we would like to use wood. The question is whether wood 
will go bad when buried in cob.

Any tips?
