Double Sided Bubble Radiant Barrier reflects heat and provides an additional R-Value
Foil Bubble wrap is a double sided aluminum bubble pack radiant barrier. It is available as Single Bubble (SB) which is approximately 1/8″ thick or Double Bubble (DB) which is approximately 1/4″. The bubble pack in the center of this double bubble insulation provides a fixed air space and thermal break. Reflective bubble wrap insulation is only available as a Non-Perforated radiant barrier.
Foil Bubble insulation is most commonly used in metal buildings, pole barns, crawl spaces, masonry walls, basements, duct wrap, and applications where other insulation is not present.
