Reflective Insulation Roll, Double Foil 48 in x 25 ft

Reflective insulation roll helps block radiant heat to keep interiors cooler in summer and warmer in winter. This double-sided aluminum foil barrier uses an EPE foam core to slow heat transfer while adding vapor control for more stable indoor comfort. Cut it to fit windows, RVs, roofs, garage doors, and workshops for fast DIY upgrades with a lightweight, foldable roll that stores easily between projects.

• Delivers 3-in-1 performance: radiant barrier + insulation + vapor control for year-round temperature stability.


• Reflects ≥95% radiant heat to reduce heat gain on hot days and limit heat loss in cooler seasons.


• Cuts easily to size for custom fits on windows, RV panels, roof cavities, garage doors, and more.


• Resists tears and punctures for durable handling in tight spaces, corners, and high-contact areas.


• Folds and carries cleanly for storage, travel builds, and quick retrofits without bulky materials.

Use this foil-faced thermal insulation roll where heat intrusion or temperature swings are a problem—sun-facing windows, RV roofs, metal garages, sheds, and attic access points. The double reflective foil surface helps bounce radiant energy away, while the foam core adds a consistent insulation layer without heavy weight. Measure your area, cut with scissors or a utility knife, and shape to your application for a cleaner, more comfortable space. Grab yours today and start sealing up the hot spots.
