Subject: [nbne] top of wall
Thanks for getting feedback to our questions. I was most interested
in the top of wall issue. Dr. Straube says air barrier, no vapor
barrier, but why. That's what I was most wanting to know, why? Is it

My question assumes that attic insulation is resting on top of the
bale wall. Is it safe to allow vapor to migrate into, say an
insulated cieling/ roof? These insulated roofs seem to be problem
areas for moisture. A vapor barrier at the top of the wall would not
be like having a vapor barrier on the outside since there is
insulation piled on top, or perhaps it may be a cold enough spot to
