Open or Closed Cell Foam Insulation?
I live in the Northeast and I am finishing my basement. I plan on using spray foam insulation and having it sprayed directly on the poured concrete walls.
I am very confused by the competing claims of open vs. closed cell contractors.
My basement has been dry for the 5 years since the house was built, but I am wondering about moisture from the concrete and/or penetration from the surrounding soil. (The foundation has been sealed on the exterior but not insulated.)
Is it better to go with the closed cell that will act as a water vapor barrier or use open cell that will allow the moisture to dry to the interior of the basement?
I am getting conflicting views on this, please help!
