This white bubble insulation, also called poly bubble insulation, has a single layer of polyethylene bubbles surrounded by a layer of radiant barrier on one side and a polyethylene sheet on the other for a cleaner appearance. The reflective foil works to reflect radiant heat from both directions while the bubble insulation provides mass for increased R value. Like all bubble insulation, this white single bubble insulation also works as a vapor barrier to prevent condensation while also stopping radiant heat transfer. Be sure to use white polypropylene tape for the seams for the most effective application.
