Specifications
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.
Radiant Heat Reflection for Metal Buildings & Utility Spaces
Single Bubble Foil Insulation reflects 96% of radiant heat and emits only 4%, helping maintain more stable temperatures in unconditioned or partially conditioned spaces. Radiant barriers are evaluated by reflectivity and emissivity instead of R-value, making them a strong complement to traditional insulation. When paired with fiberglass or foam, this product enhances overall system performance in both warm and cool seasons.
Lightweight, Easy-to-Install Bubble Insulation
The thin bubble layer provides structure without added bulk, making it ideal for tight or awkward spaces where traditional insulation is difficult to install. When taped properly, the material forms a moisture-resistant barrier that helps control condensation and supports long-term building health.
