This is a roll of reflective foil insulation built around a closed-cell foam core, with a self-adhesive backing for sticking it to garage doors, ducts and other flat surfaces. The foil face reflects radiant heat while the foam slows conductive heat flow, so it works as a radiant barrier rather than as bulk cavity insulation. It suits garages, sheds, duct wraps and metal buildings where cutting and pressing panels into place is easier than framing. Compared with plain bubble foil, the foam core is stiffer and less prone to crushing, but it still delivers modest R-value on its own.
