Does midwest cabin w/o insulation need VB
I have a cabin in central Missouri with T111 siding that needs replaced. It does not have insulation in the walls. I do not plan to put any insulation in the walls. I do not know if there is a vapor barrier. If I replace the T111 with Hardiepanel or LP Smart Side panels, should I put in a vapor barrier under the panels? If so, what do you suggest?
