Condensation - It can seem like a tropical rain forest inside an unprotected metal building. 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.

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 framing and sheeting rapidly radiate the sun's heat into a building.  

Cold - 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.

Insulation In Metal Buildings That Lose R-value 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 metal building - 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 framing. If you insist on using fiberglass, use it in conjunction with Prodex Total, so the Prodex can keep the moisture out of the fiberglass.

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 Buildings That Don't Protect Against Radiant Heat Transfer

Like fiberglass, spray foam insulation doesn't protect against radiant heat transfer. Without a radiant barrier, when your roof gets hot it radiates solar-generated heat down. 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  Metal Building Insulation Solves Condensation, Heat and Cold Challenges

Prodex Total Eliminates Condensation in Metal Buildings

condensation in metal building

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. 

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 Keeps Your Metal Building Warm

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 building and your insulation must work in these conditions.

How To Insulate A Metal Building - 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. Pinching 6 inches fiberglass between the framing and sheeting is not easy. It's really tough having to use a wire mesh to hold fiberglass in place on an existing building. Spray foam is not DIY friendly.

Prodex Total can be installed before or after your metal sheeting. For fastest and easiest installation, install before applying your sheeting.

New Buildings: lnstall the insulation over your purlins and girts (sandwiching it between the sheeting and the purlins/girts). Existing Buildings: lnstall the insulation on the underside of your purlins and girts. For instructions: Metal building installation methods

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 interior.

I finally completed my 60" X 42" steel building using your insulation between the steel studs and the metal sheeting. I was amazed at the temperature difference. The metal is not allowed to adversely heat the building and the temperature is cooler than under a shade tree because of the breeze created within the door openings. The reflective foil also provides a tremendous amount of light reflection inside the building creating a very bright look inside. I am amazed and presently surprised that the thin foil actually worked so well.

I installed Prodex in my 40'x40'x14' Steel garage when I bought the building it came with the 4" thick 6' wide white vinyl that was hard to work with because of it's weight and bulkiness. The weather was rainy and it was just my wife and I installing the insulation and steel sheeting. Trying to find something easier to work with I found your product I ordered enough to line the entire garage it was grate to work with. When the garage door company cam to install the garage doors on January 02/2010 the temperature outside was 10 degrees and windy. After they had the door tracks fastened enough to hold the doors in place they light there portable gas salamander I was impressed with how quickly it warmed to 40 degrees and healed the heat after they turned it off.
