People ask us what the difference between BlueTex™ insulation and bubble foil products is and the main difference is what it is made from. BlueTex™ is made of pure aluminum foil bonded to an EPE (2mm and 3mm) or XPE (6mm) foam creating a super combo that blocks radiant heat and provides an excellent vapor barrier too. Because we use pure aluminum on all of our products, you don't have to worry about performance or lasting-power; the same can't be said for similar insulations that use inferior materials.
We’ve been in business since 2006 when Ed started AtticFoil.com. Even from the very beginning we had questions about insulation for metal building projects. Sadly, we just could not ever recommend a foil and foam (or foil and bubble) product because they just were not durable enough to earn our endorsement.
DID YOU KNOW? Most bubble foil products use what’s called MPET or metaled film also known as “mylar” basically it’s a potato chip bag. The aluminum in bubble foil products is actually “vapor applied” so it is 1/200th the thickness of the pure aluminum sheet we use in our products and applied to a clear sheet of plastic. Basically, bubble foil products are 100% plastic and will degrade over time due to the intense heat coming off the metal on a building.
All BlueTex products use a PURE ALUMINUM LAYER that is 200 times thicker than the aluminum on metalized film products. This layer ensures a durable product that will not degrade from heat from the metal building. Plus BlueTex™ uses high-density foam as its core, so you get a strong, fire-resistant base that can handle heat and vapor with no problem.
This is one of the biggest reasons we developed BlueTex™ insulation. We have made it super durable and installers tell us all the time how much they love this product because no matter how hard you pull, you can’t tear it! You can throw a baseball against it without leaving a mark, and you can even power-wash it if it gets dirty.
Below are some photos of buildings that have/had bubble foil insulation. As you can see, the product becomes brittle and flakes off after time. The problem with bubble foil products is that they are 99.999% plastic. Watch this video of a guy who documented his bubble foil failing.*Click on an image to enlarge it.*
Don't waste your time with these inferior options, BlueTex™ insulation is the superior vapor barrier and radiant barrier choice for metal building insulation.
