Double Bubble Insulation Compared to Single Bubble

Bubble insulations are composed of either one (single bubble) or two (double bubble) layers of air bubbles sandwiched between two metalized surfaces. Once either is punctured, it collapses. Single bubble has a nominal thickness of 5/32 inch. Double bubble measures 5/16 inch. These measurements bear little resemblance to the effective measurement of the products (see photos above).

We see little difference between the performance of single and double bubble insulation. The latter simply has a second layer of air bubbles (A balloon with more air). Although we strongly recommend Prodex Total over either, if your budget doesn't allow you to purchase the quality of Prodex, we suggest you order a single bubble insulation rather than a double bubble. You'll get virtually all the benefits of the double bubble while saving money. We do not offer double bubble because we aren't able to justify its pricing relative to Prodex Total or single bubble.

Prodex Total Insulation vs. Double Bubble Insulation

Double Bubble Insulation and Prodex Total are both suitable for metal buildings, pole barns, homes, attics, roofs, walls, crawlspaces, garages and more - These silver colored insulations provide R-value, a radiant heat barrier and vapor barrier protection.

Take a look at the photos above. Even if you didn't know anything about double bubble or Prodex Total, which one would you choose? The obvious choice is Prodex Total. It has a high quality core that keeps its shape when exposed to forces. Prodex Total has a nominal thickness of 5mm (13/64 inch) closed cell polyethylene foam covered on both sides with .0012 (00.03mm) aluminum foil facing. Under pressure, the Prodex micro-cells and do not collapse -- With a pressure of 6 PSI Prodex compresses just 6%. When the load is relieved it takes back its initial shape. The density of the foam is between 1.25 lb/ft (sq) - 1.87 lb/ft (sq). This gives the material real body. 

Foil Only Radiant Barriers

Foil Only radiant barrier are typically perforated and composed of two metalized surfaces with a mesh woven in for strength. It is not a vapor barrier - It is not insulation. Because foil only products have no membrane (substance between the layers of reflective material) transference of heat and or cold can occur. Bubble insulation solves the issue of heat and cold transference by using air bubbles between the reflective surfaces. We recommend a bubble insulation over a foil only product.

Summary: Bubble insulation is superior to foil only radiant barriers because it has an inner substance. Bubble insulation provides a radiant barrier, a vapor barrier and thermal protection. The better value bubble insulation is single bubble because it provides virtually all benefits of the double bubble insulation while costing less. Because bubble wraps have a core composed of air rather than closed cell polyethylene foam, they lack the long-term consistency in performance of Prodex Total Insulation.
