The 48″ wide solid is a vapor barrier & radiant barrier in one! If you're looking for a vapor barrier that also reflects radiant heat, this is the right product. This foil is rated as a VAPOR RETARDER will block/trap moisture. This material can be paired with a traditional roofing underlayment or be used in a crawlspace to stop moisture from coming up. It's also popular for SCIF and EMF shielding applications.
