Insulating a P.W.F. (Permanent Wood Foundation)
I purchased a house with a PWF a few years ago in southern Michigan. I am interested in finishing the basement now, and would like some advice on insulation options for the walls. The pwf is constructed of 2×6’s on 12″ centers with 3/4″ exterior plywood. From what I can see the outside is wrapped with a some type of poly / plastic wrap, and I don’t believe there is any exterior foam type insulation. I would say most of the walls are completely below grade, but certainly some portions that are not – if that impacts the insulating plan. The floor is a concrete slab, it does have drainage below with a sump-pump.
Please let me know if there are any other pertinent details that are needed…
Thanks in advance.
