EcoFoil Double Bubble Foil Insulation is primarily used in pole barnsmetal buildingsbasement wallscrawl spaces, and storage units located in moderate and colder climates. Double bubble insulation combines the heat-shielding properties of solid radiant barrier with two layers of polyethylene bubbles, which acts as a built-in air gap that reduces contact between temperatures on either side of the product. The double 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 1/4"), 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.


A radiant barrier and vapor barrier, all in one product

Not only does Double 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. 

 

Radiant barrier vs traditional insulation

Radiant barrier bubble insulation works differently compared to traditional insulation like fiberglass and spray foam.

  • Traditional insulation works to absorb heat and is measured by R-value. The higher the R-value, the thicker the material and the more heat it can absorb. 
  • Radiant barrier bubble insulation, on the other hand, reflects heat back to its source (whether that's your furnace or the sun.)

When used together, these two insulation types can provide a highly effective one-two punch that will keep your building warmer in the winter and cooler in the summer.

R-Value Of Radiant Barriers

Because these two insulation types have different purposes, their effectiveness is measured differently. Rather than rating by R-value, all radiant barrier products are measured by their reflective and emissive properties. When installed properly with an air gap on one side of the product, double bubble insulation will reflect heat away from your building in the summer, and keep heat in during the winter.

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.  



EcoFoil Double Bubble Foil Insulation is not to be used under concrete slabs. For under concrete slab or radiant floor insulation applications, we recommend EcoFoil Under Slab Insulation.

thinner than described

have not had it installed long enough to know how well it will do. i will say the company shipped the product fast with tracking and was delivered on time. everything arrived in good shape it’s just maybe 3/16 of an inch thick not the 5/16 as advertised.

Great product. Does what it says it does

Love the insulation

Worth every penny! Highly recommend the double bubble insulation. The only complaint is that the tape is a waste of money and does not need to be sold until reengineered, I wasted $150 on tape. After wiping the insulation down to remove any dirt particles the tape did not stick after 12 hours and ALL of it came down. The Insulation itself is awesome and has made a world of difference in our cow barn and we highly recommend it. Great product for the dollar.

The roll I received was seamed rather than a full roll. I did not expect that.

Works well but too flimsy

Now that I finished insulating the ceiling in my 24x30 metal garage, I can say that there is quite a noticeable difference and temperature and it looks great. However, doing this on an existing building, I found the product to be very flimsy making it a little more difficult than I have planned.
