Is it advisable to add an additional plastic vapor barrier to the paper backed insulation for a house in MS? The exterior walls are wood siding then foam board then the insulation and then drywall.
When we put the insulation back is it worth putting a plastic vapor barrier between the insulation and the drywall? I know this is common up north with the winters but would anything be gained by doing this down south where it gets really humid.
