Prodex adds an extra layer of credibly by submitting insulation rolls to the ASTM Rima International verification program. By having a third party verification, Prodex assures its clients that the insulation complies with industry standards, and is suitable for any construction system.

Beware of pitchmen for fiberglass and other mass insulation products. Ask them: "Doesn't the R-value you post come from the air pocket in the fibers? Isn't your testing done in an environment with no moisture? Why don't you show the parameters of your testing? Unlike mass insulation products, we provide the parameters of the testing. Every R-value on website is displayed as a link. Every R-value link goes to the parameters of the testing. 

You get more than insulation when buying Prodex Total. You also get an air, radiant, and vapor barrier! Even if you have fiberglass insulation, you should still use Prodex Total to add r-value and keep moisture plus heat out of your fibers.

48 INCH - Prodex Total 5M Plus Insulation - Combines the benefits of insulation with vapor, air and radiant barrier protection. That means you'll have a cool, dry structure in the summer and a warm, dry structure in the winter

Prodex works great in hot and cold climates. 

In addition to being the best  metal building insulation, it is also a vital component in a complete house insulation system. 

Fiberglass used as metal building or pole barn insulation results in condensation, loss of R-value, and heat gain.

Reflective Insulation - The R-values of reflective and mass insulation are based on the same fundamental equation -- The ability to stop heat transfer.

My Pole Barn

December 8th, 2020
I have built a 42 X 74 X14 pole barn. I decided to use Insulation 4 less for the side walls as I am going to finish off the walls. I live in northwest Ohio and it gets cold here. I have installed the 5M insulation as per the instructions. The temperature has been in the low 30' this December. I keep the heat set at 45 degrees when I'm not working out there. Evenings I go out to check the heat consistency with the use of an Infrared Camera. All of the walls are a constant reading. I have thermostats all around the barn so I can evaluate the consistency of my Radiant Tube heating coming from the Ceiling. All thermostats read 50 degrees which is warmer than my Heating Units setting of 45 degrees. It has to do with the reflectiveness of the 5M insulation I guessing as to why the barn is warmer than the main setting. Very impressed with this.

Great Product and Fast Delivery!

December 7th, 2019
I was skeptical at first but I must say I'm pleased with the product and delivery time. I ordered the 24 inch and the 48 inch. It was flexible and installed easily in my crawlspace. I put the 24 inch in between my studs and the 48 inch below. Previously, I had fiberglass and a lot of mold. I'm sure that wasn't very healthy for me. I remember ordering on a Monday and was surprised to see them on my porch a couple days later.

A/C Relief

July 22nd, 2019
I doubled the size of my shop. It is now 3200 square feet. I added a 5 ton A/C system. The walls were insulated but the open ceiling was not. The new unit would not keep up with the load. I forgot to mention that the shop has a metal roof. I purchased Prodex insulation online and had a contractor install it on the underside of the rafters. The A/C went from not being able to keep up to being able to keep the shop whatever temperature I like.
