Open-cell foam with Tyvek?
We will be starting a new home next year. We are located in the mid lower peninsula of Michigan. We are going with the standard 2×6 exterior framed wall, with sheathing, Tyvek, and vinyl siding on top of that. I am pretty much convinced of open cell foam inside the walls.
My question is, using open cell foam is the Tyvek a good idea for the external face of the walls (just under the vinyl siding? Any issues with this?
