Reflective Insulation Roll, 48 In x 50 Ft, 3.2 mm

Double reflective insulation roll helps reduce heat gain in summer and heat loss in winter for a more comfortable interior. This foam-core radiant barrier combines double-sided aluminum foil with EPE foam to reflect radiant heat and slow heat transfer, making it a practical choice for windows, RVs, roofs, garages, and DIY insulation projects. Lightweight, cut-to-fit, and easy to store when not in use.

Use this thermal insulation roll anywhere you need a fast, clean way to manage radiant heat—whether you’re improving an RV, lining a garage door, or adding a reflective layer under roofing and wall panels. The double-sided foil surface works in multiple orientations, while the foam core adds separation to slow heat transfer. Measure your area, cut to shape, and install using your preferred tape or fasteners for your surface. Grab yours today and start dialing in comfort with less temperature swing.
