Is bubble wrap good for insulation?

Is bubble wrap good for insulation? 

In short, the answer to this question is, yes! At EcoFoil we get this question quite often and our response is the same each time. We start off with a little education on what our bubble insulations are and how they work. We then discuss the size of rolls we have, as well as what finish our rolls come in. Lastly, we discuss how easy it is to install the product. Before we know it, there is another bubble insulation lover out there.


EcoFoil Single Bubble vs EcoFoil Double Bubble

What is the difference? To answer this question, we need to take a look at how the bubbles function in the insulation.

Bubbles are filled with air, which make a great insulator because they provide a barrier to keep the heat from transferring from one material to another. Some common items in our everyday lives that use air for insulation are coffee mugs, double pane windows and thermal mugs. This phenomenon is also what prevents condensation from forming.

As the names suggest, our single bubble insulation has one layer of bubbles, while our double bubble insulation has two layers of bubbles. EcoFoil Double Bubble insulation provides the most effective thermal break so I always recommend it for larger scale projects such as metal buildings, pole barns, and workshops.

However, there may be times when 5/16” is too thick. In those cases, EcoFoil Single Bubble insulation, which measures just 3/16", is an excellent choice.
