Under cabin insulation
I am planning my cabin build and I want to insulate the floors. The supporting beams will sit 12" off the ground, resting on Metal Techno posts, with 2x8 floor joists over the beams (16 OC). Not only do I need to insulate correctly but I most make sure that it is done in a way that insures no rodents can get in there.
I had this in mind: a 6mil plastic sheet that will be between the joists and exposed to the soil under the cabin basically. Over this, I will place 1/2" OSB - hanging between the joists, while insulation batts are resting on top of it=between the joists. This will crate an air tight environment between the joists.
I was told that this is a bad idea as the plastic sheet will trap moisture between the joists and create a mold issue.
Any thoughts or recommendations?
