Double Bubble Insulation is a multipurpose insulation for residential and commercial applications. Product is comprised of 2 layers of polyethylene bubble that are sandwiched between 2 layers of 99% pure aluminum foil.

The polyethylene encapsulated air bubbles serve as an effective thermal break as well as a vapor barrier, while the two outer layers of aluminum reflect up to 97% of all of the radiant energy.
