What is the R value of Double bubble reflective foil insulation?

Most brands of foil-faced bubble wrap are only 3/8 inch thick or less, and have an R-value of only 1.0 or 1.1. Since the product often costs more per square foot than 1-inch thick rigid foam rated at R-5, why would anyone use bubble wrap as insulation?

How much R value does Radiant Barrier add?

Radiant barrier on its own has NO R-value; R-value is attributed to materials slowing conductive heat. AtticFoil™ works to block radiant heat (97%) coming in to the attic by stapling it to the rafters, but it has no R-value.

How good is bubble wrap insulation?

How Good of an Insulator is Bubble Wrap? Bubble wrap is an excellent insulator thanks to small pockets of air trapped within the bubbles. After applying bubble wrap insulation to your windowpane from the inside, tiny bubbles serve as a network of many insulating pockets filled with air.
