EcoFoil Single Bubble Foil Insulation is designed to improve comfort and reduce moisture issues in moderate-climate structures such as pole barns, metal buildings, basements, crawl spaces, and storage areas. A single layer of polyethylene bubbles creates a built-in air gap that helps limit heat transfer and reduces condensation caused by temperature differences on either side of the material. At approximately 1/8″ thick, it is lightweight, easy to handle, and works well in both new construction and retrofit applications. The white/foil version provides the same thermal benefits as foil/foil but features a clean white finish for a more polished interior appearance.

Radiant Heat Reflection & Vapor Barrier Performance

This insulation reflects radiant energy to help maintain more stable temperatures throughout the year. When seams are fully taped, it also functions as a vapor barrier by blocking air and moisture movementan important benefit
