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 2×8 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?
