This is a 23.6-inch by 50-foot roll of double-sided aluminum foil bonded to a bubble core, sold with 60 self-adhesive pads. The foil faces reflect radiant heat, so it works as a radiant barrier on windows, garage doors, roofs and RV walls in both summer and winter. It is a cheap, low-commitment way to cut solar gain and drafts compared with rigid foam board or reflective film kits, but it is thin and has no R-value rating, so it slows radiant transfer rather than insulating like batt or foam. Owners use it for quick seasonal fixes and privacy; it is not a substitute for real insulation in a conditioned space.

Buyers treat it as a low-cost radiant barrier for windows, garages and RVs. They report it noticeably cuts sun heat and glare and is simple to cut and hang. Complaints center on thin material, weak adhesive pads and foil that creases or tears.
This reflective bubble foil insulation comes as a roll. It is made of double aluminum foil layers and a bubble-type material. The reflective surface blocks sunlight and helps keep heat out of windows in summer. It also reduces heat loss in winter, and the opaque foil surface adds privacy.
The surface resists scratches. You can cut the roll to size with a utility knife or scissors. The included self-adhesive pads hold it in place, and it can be removed again.
It can be used on windows, garage doors, garages, RV windows, roofs and houses.
