Can polyurethane vapor barriers be used along with another kind of vapor barrier?

Yes, polyurethane vapor barriers can be installed onto the paper facing of fiberglass insulation to create an even stronger barrier. This also helps to protect the insulation underneath. The polyurethane sheeting can also be used on its own if it is attached directly to the roof’s wooden decking or the attic’s rafters, trusses or floors.
