Radiant barriers can sometimes help if you’re in an area with a LOT of sun and heat. Think places like Phoenix, AZ. In most other areas, radiant barriers don’t really get you much. If you do decided to try this though, I would make sure to use a perforated radiant barrier material so that you don’t have a vapor barrier which can sometimes cause some condensation issues when installed in this location.
