Spray Foam and Batt Insulation
I thought I recently read an article on the Building Science website talking about problems installing batt insulation over spray foam - moving the dewpoint to the spray foam layer and causing the batt to get moist where it meets the foam. Now I can't find it anywhere and am wondering if I understood it correctly.
Can anyone explain this to me better or point me to more information. Thank you so much.
