RE: [GBlist] benign wall insulation

[Reuben Deumling <deumling@socrates.Berkeley.EDU>]

I've succeeded in obtaining a sufficient quantity of cotton 
insulation for this project, and I am wondering what (if any) vapor 
barrier might be appropriate on the inside of this insulation.  This 
stuff comes in batts, but not with any backing.  Does anyone on this 
list have experience with installing cotton insulation?  Thanks for 
any insights.
