Comparing Prodex to Reflectix, Tekfoil, Eco foil, Tempshield, etc

Reflectix Foil Insulation, E shield, Low e, Radiant Guard, Rfoil, Tempshield, Eco foil insulation, Tekfoil Reflective Insulation, Energy Shield Insulation and Solar Guard vs. Prodex Total Insulation

All of the radiant barrier appear to be quality products -- Each prevents radiant heat transfer (the primary source of heat-flow). The above products are composed of either no center core, single bubble, double bubble, fiberglass or closed-cell foam membranes (centers).

Let's start our discussion by defining the difference between a radiant barrier and reflective insulation. A radiant barrier is a single reflective surface used alone that faces an open space, such as a wall cavity or attic. A reflective insulation is an insulation system typically composed of closed-cell foam, fiberglass, mylar air-bubbles or shredded newspaper plus (2) low emittance reflective surfaces plus trapped air spaces.

  •  The difference between a radiant barrier and reflective insulation is one reflective surface vs. two reflective surface AND the membrane (the core between the reflective surfaces)!

The Prodex Difference:

Rather than one reflective surface, Prodex has two. Rather than mylar air-bubbles, fiberglass or shredded newspaper, Prodex Total Insulation core is composed of closed cell polyethylene foam. Rather than metal film, Prodex Total is made with reflective reinforced the foil. 

Having two reflective surfaces allows Prodex Total to reflect energy both directions! The outer reflective surfaces reflects out the heat or could coming in structure - The inner reflective surface reflects back the cool air from your air-conditioner or the warm heat from your furnace!

Take a look at the photo below. Even if you didn't know anything about radiant barriers, which product would you choose? The obvious choice from the photo is Prodex Total Insulation. It has a high quality core that keeps its shape when exposed to forces. Prodex Total has a nominal thickness of 5mm (0.2 inch) closed cell polyethylene foam covered on both sides with reflective reinforced foil facing. Under pressure, the Prodex micro-cells do not collapse. With a pressure of 6 PSI, Prodex Total compresses just 6%. With the load relieved, it takes back its initial shape. The density of the foam is between 1/25 lb/ft (sq). This gives the material real body.

Prodex Difference: 


  • Reflective reinforced foil on each side of closed-cell polyethylene foam center
  • Seals around nails (no leak)
  • Keeps its shape over time (doesn't collapse)
  • Rippled surface increases airflow
  • Green Product 
  • Passes stringent fire tests

Foil Only           Single Bubble        Double Bubble    Prodex Total

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).

Single vs. Double Bubble Insulation - Radiant Guard, Reflectix...

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 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.

Foil Only Radiant Barriers - Tekfoil, Eco foil, Rfoil, Tempsheild...

Typically perforated with a mesh woven into a single metalized surface. It's not insulation. 

Other Radiant  Barriers vs. Prodex Total

Prodex Total:

Radiant barrier + Insulation + Vapor Barrier + Air barrier - All in one product! Seals around nails (no leak). Keeps its shape over time (doesn't collapse). R-value unaffected by humidity, ICC-ES Recognized, Green Product Certified. 

One solution for Heat, Cold, and Water. It keeps your house and building cool in summer, warm in winter, and dry all year. Prodex Total works great in hot and cold climates.

My contractor had never done IR barrier before. By the end of the job, they were standing in the house to get out of the heat. "It's COOL in here. I Like this stuff." was their comment.

We bought Prodex for a couple framed buildings 45”x45” and a couple of Quansets. We attached them all so they formed a U. In late July I stuck a thermometer through the Prodex to see how hot it was on the other side. It was 130 degrees. Where I was standing it was only 80 degrees. No question it made all the difference in the world.

I had used the double sided foil to insulate my barn. Upper and lower floors. It has a concrete lower floor 36' x 36'. The upper loft is 15' x 36' with 9 foot ceilings. When it is a cold 27 out, it's a constant 43 to 45 in the lower level. I purchased the 4' rolls by 100ft. or so. My studs were 24" apart so I cut the rolls in half. I like the clean simplicity of the installation. I used 1/2" x 1/2" staples.
