Reflective Insulation Roll, Double-Sided Foil, 48 In x 100 Ft

Reflective insulation roll helps reduce heat gain in summer and heat loss in winter, supporting more comfortable indoor temperatures in RVs, homes, garages, and workshops. Built with a double-sided aluminum foil radiant barrier around an EPE foam core, it reflects radiant heat while adding insulation and vapor control. Easy to cut, fit, and fold for storage, it’s a practical option for windows, roofs, and doors.

• Delivers radiant heat reflection (≥95%) to help keep spaces cooler in hot weather and warmer in cold seasons


• Combines radiant barrier + insulation + vapor control in one roll for multi-surface energy management


• Fits DIY installs by cutting to size for windows, RV panels, garage doors, attics, and roof lines


• Resists tearing and punctures with double foil faces and dense foam core for jobsite handling


• Stores easily by folding flat for transport between projects, vehicles, and seasonal use

Use this foil insulation roll anywhere you need a lightweight thermal insulation layer without bulky batts—behind wall panels, under roof decking, over window coverings, or as a removable heat reflective shield for RV and van builds. The double reflective faces help bounce radiant energy away from the living space, while the foam core slows heat transfer for steadier comfort.
