Can tar paper be used as a vapor barrier?

Not just for roofs and sidings, tar paper is great for floors, too. You'll also find wood floor underlayment made from materials such as cork, rubber and felt. These are all suitable as long as they satisfy NWFA's permeability requirements, although they may be more expensive than tar paper or kraft paper.
Will tar paper keep water out?
Roofing felt is also sometimes called “tar paper.” It's a compact, wool-like material, usually made of either condensed fiberglass or polyester fibers, that works as a support material for roof shingles. It is not a sponge-like material, as it repels water more than it absorbs it.
Is tar paper a good moisture barrier?

Does tar paper dry out?
Moisture trapped between tar paper and and structure has no way to dry as the paper doesn’t allow for free movement of vapour to allow drying. Being waterproof may seem like a good idea, but when it means wood or gypsum board don’t dry out if they get wet or damp then it becomes a haven for mould.
