Product details:

EcoFoil Single Bubble Foil Insulation is primarily used in pole barnsmetal buildingsbasement wallscrawl 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. Our white/foil variety offers the same benefits as foil/foil, but with a white finish that faces towards your finished space, providing a more "finished" look.

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.  


Why choose a 6' roll?

EcoFoil Single Bubble White Insulation performs the same regardless of what size roll is used. A common reason for choosing our 750 sq. ft. roll is if it provides savings in installation cost or time to install. Because this roll is considered "over-sized", it makes it more expensive than our standard 4' roll. As a result, it is often more economical to go with the 500 sq. ft. roll in the same amount of square footage needed for an application. If you need assistance comparing the costs, or for a custom quote, please give us a call at (888) 349-3645 and we would be glad to help walk through this to ensure you get the product that is right for you!

A radiant barrier and vapor barrier, all in one product

Not only does Single Bubble Insulation reflect radiant heat, when properly installed with tape it also acts as a vapor barrier, preventing the passage of moisture and other unwanted particles which can cause mold. In order to establish a vapor barrier, you must tape all seams and joints to prevent air passage, keeping moisture and other particles from passing through. 


Ecofoil Single Bubble Reflective Insulation is made from a single layer of polyethylene bubbles, sandwiched between two highly reflective surfaces with a metabolized coating. This product is classified as Class 1/Class A in accordance with the ASTM-E84-09 fire test standard. The product was mounted in accordance to ASTM-E2599-08. It is lightweight, durable, and is easy to handle and install.
