I have a cabin with a single layer of berber carpet, no padding. I believe that if I pull up the carpet and put better carpet with padding, that I could stop some air infiltration from under the cabin. I definitely could uncover some spaces that need to be caulked.
But, I was considering if I should put down some thick visqueen directly over the tongue and groove flooring, and stick it with double face tape, THEN put the padding and carpet. Would the visqueen create a place for condensation? Would this be advisable, or would the padding serve the same purpose and allow the wood to breathe a little so as to avoid mold?
What would you do? I know I can't make it air tight, but right now, I have a lot of sealing to do, and I figured I'd start with the big stuff.
Thanks
