Vapor Barrier Radiant Barrier AtticFoil® Single-Sided Solid 48″ Wide - Not for Attic Use!

We do not recommend using this product in a vented residential attic. The 48″ wide single-sided 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 pure foil insulation is rated as a VAPOR RETARDER & it 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.  If you're unsure if this product is right for your application, we encourage you to contact us to speak with a specialist about your project.  Install with an air gap on the foil side that is at least 1/2" or more for the radiant barrier performance.
