Open- or Closed-Cell Spray Foam
I’m currently building a house with 2×4 exterior walls in climate zone 4. the walls are sheathed with 5/8 inch cdx plywood and will have peel and stick WRB [ Henry VP 100 ]and then all the exterior walls will have a layer of 2and1/8 inch EPS foam sheathing . A vented rain screen and board and batten siding. My question is will open cell spray foam be ok to use in the walls and bandboards?
