This is a double bubble radiant barrier: two layers of polyethylene air bubbles bonded between reflective metalized foil on one side and black vinyl-coated foil on the other. It reflects about 97% of radiant heat, emits under 3%, and is Class 1/Class A fire rated to ASTM E84 and ASTM E2599. It holds staples without tearing and resists compression, so it suits attics, garages, sheds and metal buildings where you want a thin reflective layer rather than bulk thermal insulation. Against fiberglass batts it is far thinner and easier to cut and staple, but it has little R-value on its own and works best as a radiant barrier or as a facing over existing insulation.
