This is a roll of double-sided aluminum foil bonded to a polyethylene bubble core, sold in a 47.2 in x 10 ft sheet. It works by reflecting radiant heat rather than blocking conducted heat, so it is best used as a radiant barrier on windows, garage doors, attics, roofs and RV walls. It is thin, light and easy to cut with scissors or a utility knife, which makes it a low-effort first step for a hot room or a cold draft. It is not a substitute for batt or foam insulation, and its real-world gain depends on an air gap and a tight seal at the edges.

This reflective bubble insulation sheet has aluminum foil on both sides and a polyethylene air bubble core. It reflects radiant heat and reduces heat transfer. That helps limit unwanted solar heat in warm weather and heat loss in colder seasons.
The material is lightweight and flexible, and it can be cut to fit different spaces. It is suitable for windows, RVs, garage doors, attics, roofs, and other areas where reflective insulation is needed. Install it with suitable tape or fasteners, depending on the surface.
The sheet is supplied folded. Unfold it and trim it to fit your project.
