Cob: Questions about wool- air gap venting in roof

[D.J. Henman]

David's mail seems to have answered why my wool clothes were a feast for 
moths.

However, I still prefer the idea of a clay light straw around fire 
areas.   Ideally, if you have a fire place in a central area you need no 
insulation, but rather mass around it to store the heat for when the 
fire goes out.      Wool seems alfright for attic and other applications.
