Reflective Insulation Roll, Double-Sided Foil, 6mm, 4x100 ft

Double reflective insulation roll helps reduce heat transfer by reflecting radiant energy, keeping spaces cooler in summer and warmer in winter. Built with double-sided aluminum foil and dual-layer air bubbles, this 6 mm radiant barrier insulation also supports vapor control for garages, windows, RV roofs, house walls, and attic or bungalow roof projects. Cut it to size for fast DIY installs and fold it away when not in use.

• Delivers ≥95% thermal reflectivity to help block solar heat and reduce heat loss


• Combines radiant barrier, insulation, and vapor control in one multi-layer roll


• Resists tears and punctures with scratch- and wear-resistant foil bubble construction


• Fits garages, windows, RVs, roofs, walls, and sheds for year-round temperature support


• Installs easily—cut to shape, apply as needed, then fold for compact storage

Upgrade your build or retrofit with a lightweight thermal insulation roll designed for quick coverage and consistent performance. The double aluminum foil surface helps reflect radiant heat, while the trapped air-bubble layers slow conductive transfer—ideal for hot garages, sun-facing windows, and RV or camper roof areas. Use it as a heat reflective shield behind panels, under roofing, or along doors to improve comfort with minimal bulk. Grab yours today and size it exactly to your project.
