Can someone give me the code reference for interior vapor barrier
requirements over insulation.  I'm specifically trying to find the
requirement (if any) for a vapor barrier over open cell foam.  The research
I've done seems to indicate the need for a vapor barrier over open cell but
there seem to be a few other opinions out there as well with regards to our
part of the country.  Just wondering if the code addresses this specific
situation.  I'm sure this question will also spark a good foam vs. anti-foam
debate so I look forward to learning from that as well.

 

Thanks

 

Ken
