I agree about removing what is there under those conditions. However I
don't recommend batts for this use. Blown in insulation will provide some
vapor barrier and will help seal air leaks that are likely to be plenty. I
would not use plastic as I have heard of too many situations in these old
homes that doing so ended up trapping moisture where it caused problems.
