EcoFoil Single Bubble Foil Insulation is primarily used in pole barns , metal buildings , basement walls , crawl spaces , and storage units located in moderate climates. Single bubble insulation combines the heat-shielding properties of solid radiant barrier with a layer of polyethylene bubbles, which acts as a built-in air gap that reduces contact between temperatures on either side of the product. The layer of bubbles effectively combats the formation of frost and condensation that can occur when temperature differences are extreme on either side of the material. It's very thin (approximately 1/8" thick), lightweight, and installs easily with minimal equipment.
Important - You must tape any seams on the insulation. By doing this, the product acts as one sheet and maintains the moisture barrier. EcoFoil Single Bubble Foil Insulation is not to be used for under slab applications as the radiant barrier product is exposed. We offer a specific EcoFoil Under Slab Insulation where the radiant barrier is encapsulated between two layers of bubbles.
R-Value Of Radiant Barriers
Rather than rating by R-value, all radiant barrier products are measured by their reflective and emissive properties. EcoFoil single bubble insulation is 96% reflective and 4% emissive, meaning the product only allows 4% of radiant heat to pass through.
There are some companies out there posting big R-Value numbers for their radiant barriers, but those numbers are rating the entirety of the system—including the product, air gap, and other building materials. In reality, most radiant barriers by themselves have little to no R-Value. If you need to satisfy a building code of a specified R-Value, we recommend the use of a traditional insulation in conjunction with our radiant barrier in order to meet code. For more information on R-values, see our How It Works page or contact a member of our friendly service team via chat, by calling (888) 349-3645, or using the form here .
