This is a double-bubble radiant barrier: two layers of air bubbles bonded between two reflective aluminumized polyester faces. It reflects about 97% of radiant heat and is rated Class A / Class 1 on the ASTM E84 test. It is a radiant barrier, not a mass insulator, so it works best in attics, garages, sheds and behind radiators where blocking radiant heat is the goal. Compared with fiberglass batts it is thinner and easier to staple up, but it adds little R-value on its own.
