What is the Difference between Single Bubble and Double Bubble Insulation?
Bubble insulation is composed of either one (single bubble) or two (double) layers of air bubbles sandwiched between two metalized surfaces. Once either is punctured, it collapses (POPS)! 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 (photos above).
We see little difference between the performance of single and double bubble wrap 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 single bubble insulation rather than a double bubble. You'll get virtually all the benefits of the double bubble while saving money.
Because bubble insulation has a core composed of air rather than closed cell polyethylene foam, it lacks the long-term consistency in performance of Prodex Total 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.
Unlike foil only products (no inner substance), Prodex Total protects against the energy transferred via conduction and convection. Prodex is a radiant barrier + insulation + 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!

Prodex Total Insulation Solves Condensation, Heat and Cold Challenges
Any metal building or pole barn that uses fiberglass insulation rather than Prodex Total will have moisture issues (hidden behind facing), Loss of R-value (consequence of the moisture) and heat gain. Prodex Total is also a vital part of a complete house insulation system.

Prodex Total Eliminates Condensation
Prodex eliminates the moisture and ice dams from forming on roof and walls. When the heat or cold from outside comes through the sheathing it hits the outside aluminum facing of Prodex and is reflected back upwards through the underside of the sheathing. This process keeps the sheathing temperature consistent on both sides. In addition, the inside layer of aluminum in Prodex reflects away the heat (heater) or cold (air-conditioning) from inside the building, from getting to the sheathing. This also helps in preventing condensation
Prodex Total Insulation (Vapor Barrier, Class 1. perm<0.1 ).
Prodex Total Prevents Radiant Heat Transfer
Prodex Total reflects 97% of the radiant energy (primary source of heat flow) that strikes it. Prodex also reflects back the heat inside your building or home. Each unit of radiant heat energy that is reflected away from your building or home in the summer, and each unit that is reflected back during the winter, means less operation of your heating and air conditioning system - Less wear and tear on your equipment - Less money you pay in utility costs.
Prodex Total Keeps You Warm
The Prodex Total R-value is not affected by humidity. This feature cannot be over emphasized. There is humidity in every location. Your insulation must work in these conditions.
Prevents Rodents, Bugs and Birds from Nesting
Unlike fiberglass insulation, Prodex does not provide for the nesting of rodents, bugs and birds. Rodents, bugs and birds aren't able to digest the aluminum.
Deadens Sound of Rain and Hail
Metal skin on a building can exaggerate the sound of rain and hail. Prodex has an excellent 19db sound deadening.
Increased Lighting Efficiency
Prodex provides a bright, attractive finish to your building. It reflects the light, making it easier to light the building interior.

4 ft x 125 ft roll. Single bubble reflective insulation composed of 1 layer of 5/32 inch (4mm) polyethylene bubble sandwiched between one metalized, low emissivity surface and white polyethylene.
Bubble insulation lacks the quality core and reinforced surface of Prodex Total. It takes more than metalized film and air to make a quality insulation. If you only have metalized film 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 reinforced foil to make a great insulation.
