EcoFoil Single Bubble Foil Insulation is designed for moderate-climate buildings that need dependable radiant heat control and moisture protection. Commonly installed in pole barns, metal buildings, basements, crawl spaces, and storage areas, this insulation features a single bubble layer that creates a built-in air gap. This helps reduce temperature transfer and limits frost or condensation when warm and cold surfaces meet. At only 1/8" thick, the material is lightweight, flexible, and easy to install with basic tools.

Important: All seams must be taped to maintain a continuous vapor barrier. This prevents moisture passage and allows the insulation to perform as intended. EcoFoil Single Bubble Foil Insulation should not be used under concrete slabs, as the foil surface would be exposed. For slab applications, EcoFoil Under Slab Insulation is recommended.

Radiant Heat Reflection for Metal Buildings & Utility Spaces

With 96% reflectivity and only 4% emissivity, this reflective insulation significantly reduces radiant heat transfer. Unlike traditional insulation that relies on R-value and absorbs heat, radiant barriers reflect heat away from the surface. When required to meet a specific R-value, this product works best when paired with traditional insulation materials.

Lightweight, Easy-Install Insulation for a Finished Look

The thin, flexible construction simplifies installation in tight or irregular spaces. The white/foil version adds a cleaner interior appearance, making it a good choice for exposed applications where aesthetics matter. It cuts easily, installs quickly, and adapts well to a wide variety of building materials and framing layouts.
