Foil double bubble foil with multipurpose insulation, which is comprised of 2 layers of polyethylene bubbles that are sandwiched between 2 layers of 99% pure aluminum foil. The polyethylene encapsulated air bubbles served as an effective thermal insulation as well as vapor barrier, while the two outer layers of aluminum reflect up to 97% of all of the radiant energy. This product is also available in a Foil Single Bubble Foil format.
