Single Bubble Insulation – Foil/Foil – 4′ x 125′ (500 sq ft)

EcoFoil Single Bubble Foil Insulation provides an effective radiant heat solution for moderate-climate structures such as pole barns, metal buildings, basement walls, crawl spaces, and storage units. Its polyethylene bubble layer forms a built-in air gap that slows heat transfer and helps limit frost and condensation caused by temperature differences on opposite sides of the material. At approximately 1/8″ thick, this lightweight insulation is easy to cut, position, and secure with basic tools.

Important: All seams must be taped to ensure the insulation performs as a continuous vapor barrier. This product is not designed for under-slab applications, as the radiant barrier surface remains exposed. For slab or radiant floor projects, use EcoFoil Under Slab Insulation, where the barrier is fully encapsulated.
