Insulation in Steel Arch Building - Prodex Total

Prodex Total Keeps Your Quonset Building Warm

Winter temperatures turn metal sheeting cold. The cold sheeting chills the inside of your building making it like an ice box  - colder inside the building than out.

The Prodex Total R-value is not affected by humidity. This feature cannot be over emphasized. There will always be some humidity in a metal arch building and your insulation must work in this condition.

Radiant Heat - Mid-summer sun rays hitting the metal sheeting radiates downward (inside). It can make it unbearably hot and humid inside. The metal skin magnifies the heat of the summer and frigid temperatures of the winter. Metal is a very good conductor of heat and cold. In hot weather, metal sheeting rapidly radiate the sun's heat into a building. 

Condensation - It can seem like a tropical rain forest inside an unprotected metal quonset. It's worse on those days where there is a greater contrast between temperatures at night vs. day. The morning sun hitting the cool metal sheeting will create a drip. When warm air comes in contact with the cool metal sheet, condensation occurs. A temperature difference between the outside and inside of your building creates condensation - Similar to what happens when you have a cold can of beer outside on a hot day.

Insulation In Quonset Homes and Buildings That Lose R-values Due to Moisture

Once fiberglass insulation gets wet (and it will get wet, due to condensation) it will lose R-value! Water trapped between fiberglass insulation and the exterior of a building will also cause mold, fungus growth, rust and oxidation - Conditions that will degrade the metal and shorten the service of the structure. In addition, fiberglass insulation does not prevent radiant heat transfer (the primary source of heat-flow in and outside your building).

Take a look at the white vinyl facing the next time you're in a quonset (if you can still find fiberglass in a quonset) - It will be either sagging, or sagging and flaking. This is due to the added weight of water. Behind the white vinyl is a wet, mold filled blanket that will eventually cause the white vinyl to crack and fall off. At some point, when you're exposed to the toxic fibers, you'll be forced to remove the insulation - Hopefully before it does too much damage to the metal sheeting.

Once metal sheeting gets cold it creates a situation where it's colder inside the building than out. To combat this you need an insulation that doesn't lose its thermal protection (like fiberglass) when you need it most - Cold damp conditions!

Insulation For Steel Arch Buildings That Doesn't Protect Against Radiant Heat Transfer

Like fiberglass, spray foam insulation doesn't protect against radiant heat transfer. Without a radiant barrier, when your sheeting gets hot it radiates solar-generated heat inside. This often results in it being hotter in your building  than out. Since open cell foam providers suggest you supplement open cell foam with a vapor barrier. Why not get the vapor barrier, insulation and radiant barrier all in one product?

Prodex Total  Quonset Hut Insulation Solves Condensation, Heat and Cold Challenges

Prodex Total Prevents Radiant Heat Transfer in Metal Buildings

Prodex reflects 97% of the radiant energy (primary source of heat flow) that strikes it - Which also protects your animals from Black Globe Effect. Prodex also reflects back the heat inside your steel building. Each unit of radiant heat energy that is reflected away from your barn 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. Fiberglass and spray foam insulation do not prevent radiant heat transfer.

Prodex Total Eliminates Condensation in Metal Buildings

Prodex eliminates the moisture (condensation) from forming on the metal sheeting. It does it by making the temperature of the metal sheeting on the building approximately the same on the inside as the outside. When the heat or cold from outside comes through the metal skin it hits the outside aluminum facing of Prodex and is reflected back upwards through the underside of the metal sheeting. This process keeps the metal sheeting 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 metal skin. This also helps in preventing condensation.

How To Insulate A Quonset Hut - Install Instructions

It's a lot easier and less expensive to install a 5mm roll of Prodex than a bulky 6 inch roll of fiberglass or spray foam. It's really tough having to use a wire mesh to hold fiberglass in place. Spray foam is not DIY friendly.

More benefits of Prodex Total Insulation

Protects Content From Vapor

Prodex is a class 1 vapor barrier. A vapor barrier (moisture barrier) refers to any material that prevents moisture from passing through the walls or roof of a building. This material can be plastic or better yet, Prodex Total Insulation - 13/64 inch, 5mm closed cell polyethylene foam covered on both sides with .0012-inch (00.03mm) aluminum foil facing. Prodex Total Insulation (Vapor Barrier, Class 1. perm<0.1 ).

Prodex Insulation 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.

Prodex Total 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's interior.

How do I know this is a great product?

Prodex Total is ICC-ES recognized. BBB link bottom right of every page. Real-time customer comments on every product page. Independent reviews (bottom right of every page).

To meet the unique insulation requirements of a metal building you need a total insulation system -  Prodex Total Insulation = Insulation + Radiant barrier + Vapor barrier.

Reviews - What to Believe


Helmuth Serjogins: Thursday, August 27, 2009


Hey there! I used your insulation to insulate my steel building which I bought from "SteelMaster" steel buildings. The building manufacturer recommended using fiberglass type insulation. I used your top of the line insulation because I knew here in Wisconsin condensation would be a problem during the winter months. I have radiant in-floor heat and keep it set at 45 degrees F. If the building was kept closed up, it probably would dry out (as it does on weekends), but I run a mobile tool business and the overhead door is opened at least twice a day, five days a week. Also add the moisture when the ice melts off the truck and you have a wet environment. If I had gone with the fiberglass insulation it would have "water-logged" in a short time, not to mention the smell of it. Your product allows the moisture to just run off and still retain product stability and form. Soooooooo..... contact the steel building companies and have them sell your product instead of the fiberglass stuff! Everybody will win, you can even use me for an endorsement!
