Description: aluminum foil bubble film
Aluminum foil bubble film is comprised of layers of polyethylene air bubbles (single/double) sandwiched two layers of 99% pure aluminum foil. The polyethylene encapsulated air bubbles serve as an effective thermal break as well as vapor barrier, while the two outer layers of aluminum reflect up to 97% of all of the radiant heating energy.
