This is a 36-inch by 15-foot roll of double-layer aluminum foil around a bubble core, sold with 65 pairs of 2 cm hook-and-loop tape for mounting without drills. It reflects radiant heat rather than adding bulk insulation, so it works best on windows, garage doors, RV walls and other surfaces where you want to cut solar gain or keep heat in. It cuts with scissors and folds flat for storage, which makes it more flexible than rigid foam board but less effective than thick batt or spray foam where real R-value matters. Owners use it as a cheap seasonal fix, not a permanent building material.

The fowong Reflective Insulation Roll is an aluminum foil bubble insulation that measures 36 inches by 15 feet. The aluminum foil improves reflectivity and provides heat insulation, which helps reduce stress on heating and cooling systems. A vacuum laser layer blocks heat conduction.
It can be used on windows, RVs, cabins, cars, attics, garages, walls, floors, sheds and greenhouses. It cuts easily with scissors, and the tear-resistant construction handles repeated use. It also helps protect privacy on windows.
The roll comes with 65 pairs of 2 cm hook and loop tape, so no drilling is needed. The tape attaches to wood frames and vinyl and removes cleanly for seasonal use. The insulation folds flat for off-season storage. It ships folded, so it may arrive with creases, which rebound and repair over time without affecting use.
