How to compare radiant barrier foil insulation to radiant barrier paints. This video goes through the different variables with installing radiant barrier spray paint so you can get a good understanding of the differences between radiant barrier paint and radiant barrier foil insulation. **Spoiler alert** the paints technically are not "radiant barriers" since they do not reflect at least 90% of the radiant heat!

Radiant Barrier AtticFoil ALWAYS reflects 97% of the radiant heat. Different radiant barrier paint reflect between 15-75%. When you consider that plus variables such as painting the rafters, how thinly the paint is applied (or if water is added to the paint) can all affect the final effectiveness, it's a no brainer.
