Comparing Foil Insulation

Which Foil Insulation Would You Choose?

Foil Only                      Single Bubble Foil Insulation   Double bubble Foil Insulation      Prodex Total

Foil insulation - foil foil, single bubble, double bubble and Prodex

Take a look at the photos above. Even if you didn't know anything about foil insulation, you would likely select the correct product - Prodex Total Foil Insulation. Why? - Because you get more insulation! There are some cases where more doesn't translate to more value - Why R-value of mass insulation is almost meaningless.

Prodex Total 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. Prodex seals around nails - That's important - Most installation methods require stapling, nailing or screwing the foil insulation to a surface.

Prodex Total, Single Bubble and Double Bubble foil insulations, are all suitable for metal buildings, pole barns, homes, attics, roofs, walls, crawl spaces, garages etc - Providing R-value, a radiant heat barrier. Foil only products are not recommended for these applications. 

Double Bubble and Single Bubble Foil Insulation - Balloons That Burst

Double bubble and single bubble foil insulation is composed of either one (single bubble) or two (double bubble) layers of air bubbles sandwiched between two metalized surfaces. The rows of air bubbles play the important role of separating the reflective foils. These products are more than just a radiant barrier, they're considered foil insulation.  Unfortunately, air is not as effective a separator as closed cell foam; therefore, long-term performance can be a concern.

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

Foil Only Products Are Not Insulation

Foil only products are typically perforated and composed of two metalized surfaces with a mesh woven in for strength. It is not a vapor barrier, it has no R-value - It is not insulation per se. It's a thin layer of reflective low emissivity film installed with an airspace to block radiant heat transfer between a surface that radiates heat. We refer to these products as foil only radiant barriers.

Quality Core Surrounded by Reflective Foil Facing = Quality Foil Insulation

Prodex Total Foil Insulation - Unlike foil only products (no inner substance), This foil insulation protects against the energy transferred via conduction and convection. Prodex is a radiant barrierreflective insulation (R-value 16) + Vapor Barrier. More than just a radiant barrier, Prodex Total is one solution for Heat, Cold, and Water. Prodex prevents condensation, heat from coming in and heat from getting out of your building!

Unlike bubble foil insulations, Prodex total micro-cells don't collapse in time. Rippled surface promotes air-flow. Increased lighting efficiency. Because the Prodex core is closed cell foam instead of only air bubbles, it also seals around nails, provides 19dB contact sound reduction, Class 1 vapor barrier with a perm<0.1., ICC-ES recognized and Energy Star Qualified. It is composed of 13/64 inch, 5mm closed-cell polyethylene foam covered on both sides with .0012-inch (00.03mm) aluminum foil facing).

Prodex Difference: Energy Star Qualified : ICC-ES Recognized : R 16 unaffected by humidity : Prevents condensation : Prevents 97% of radiant heat transfer : Vapor barrier : Core sealed on both 175' side with flange : Elastic : 19dba contact noise reduction : 90 degree celsius (194 fahrenheit) contact temperature rating : UV resistance : Does not promote mold or mildew : Does not provide for nesting of rodents, bugs or birds : Seals around nails (no leak) : Reflective aluminum foil on each side of 5mm (13/64) closed-cell polyethylene foam center : Keeps its shape over time (doesn't collapse) : Rippled surface increases airflow :  Member of US Green Building Council - Made with 100% recyclable virgin raw materials : Over 2 billion square feet sold worldwide

Order Button foil insulation


It takes more than foil and air to make a foil insulation. If you only have foil and a mesh than you don't have insulation. If your product is composed of air bubbles it's subject to collapse in time or lose effectiveness when punctured. It requires a quality core of foam and aluminum to make a good foil insulation.
