EcoFoil Single Bubble Foil Insulation is designed for moderate-climate buildings that need reliable radiant heat control and moisture protection. Commonly used in pole barns, metal buildings, basement walls, crawl spaces, and storage areas, this insulation features a single polyethylene bubble layer that forms a built-in air gap. This reduces direct heat transfer and helps prevent frost and condensation when warm and cold surfaces meet. At just 1/8" thick and extremely lightweight, it installs quickly with minimal tools.

Vapor Barrier Note: When all seams and joints are taped, the insulation acts as a continuous vapor barrier that blocks air and moisture movement. This is essential for reducing the risk of mold and preserving the life of the structure.

Radiant Heat Reflection for Metal Buildings & Utility Spaces

With 96% reflectivity and only 4% emissivity, this insulation effectively reflects radiant heat rather than absorbing it. Radiant barriers are evaluated by reflectivity and emissivity—not R-value—so they are most effective when paired with traditional insulation in applications where a specific R-value must be met. Single Bubble Foil Insulation enhances overall system performance when used alongside fiberglass, foam, or other conventional materials.

Choosing the Right Roll Size for Your Project

The 6' roll performs exactly the same as any standard width. Many installers choose the oversized 750 sq. ft. roll to reduce labor time on large surfaces, but its size does make it more expensive than standard 4'-wide rolls. For most projects, two 500 sq. ft. rolls provide a more economical solution with identical thermal performance.
