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 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. Prodex Reviews
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 (13/64 inch) closed cell polyethylene foam covered on both sides with .0012(00.03mm) aluminum 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.

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:
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.
Radiant barrier Only:
Typically perforated with a mesh woven into a single metalized surface.
The Prodex Total Difference (two reflective surfaces + a foam core) - Prodex Total is More than a Radiant barrier - It's Also a Reflective Insulation (R-value 16) And a Vapor Barrier - All in one product! Seals around nails (no leak). Keeps its shape over time (doesn't collapse). 19 db noise reduction. R-value unaffected by humidity. Passes new E-84-10 flame and smoke tests. Energy Star Qualified, ICC-ES Recognized, Member of US Green Building Council - Made with 100% recyclable virgin raw materials.
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. Prodex = R 16 + radiant barrier + vapor barrier.
