Radiant Barrier Insulation Roll, 48 In x 250 Ft, 6.5 Mil

Radiant barrier insulation roll helps reduce heat transfer for cooler summers and warmer winters in RVs, roofs, garages, and windows. Built with double-sided aluminum foil over a PE woven fabric core, this 6.5 mil reflective insulation is designed to bounce radiant heat and slow thermal loss. The roll cuts cleanly for fast DIY coverage, then folds for compact storage between projects.

When heat builds up fast, the right reflective insulation can make a noticeable difference in how a space feels. Use this woven radiant barrier as a heat reflective shield behind panels, under roofing, or across large window areas to help manage radiant heat where standard coverings fall short. With long roll length and durable layered construction, it’s ready for big coverage jobs and quick touch-ups alike. Grab yours today and start insulating the areas that take the most sun.
