I've got an old house and the walls have zero insulation in them. In as much as my house is a wooden structure (no brick), I have read some articles about using loose/blown-in insulation, however, as there is no vapor barrier to the interior or exterior walls and the insulation will trap moisture and eventually cause wood rot a the base of the walls where the moisture condensates at.
I'm interested in insulating my home's exterior walls and maybe spray foam might be the answer. My interior walls are lath and plaster and the outside walls are pine with 2 x 4 studs between. If I get a contractor to do a spray foam insulation into the walls, they would have to do it from the exterior.
A couple of questions:
1. Will the spray foam create a vapor barrier or would I encounter the same moisture problems as I would with loose blown-in insulation?
2. Any recommendations as to open vs closed cell foam?
Any other advice or recommendations would be greatly appreciated.
Thanks!!!!!!!
