Comparing Metal Building Insulations - Prodex, Fiberglass, Spray and Bubble
Don't buy a metal building if you're not going to insulate it -
You'll experience excessive heat, cold and water!
- Metal building condensation - It can seem like a tropical rain forest at times inside an unprotected metal building. A temperature difference between the outside and the inside of your building will create condensation (dripping on the sheeting) - Similar to what happens when you leave a cold can of beer outside on a summer day.
- The sun's rays on the metal surface transfers radiant heat inside making it unbearably hot and humid inside the building during summer months.
- Cold winter temperatures on the metal sheeting turns the sheeting cold. The cold sheeting creates the effect of an ice box making it even colder inside the building than outside.
The term "metal building" also means steel building, metal barn, metal shed, metal shop, metal bldg, metal building kit, riding arena, pre fabricated metal buildings, prefab metal buildings, pre-engineered buildings, prefabricated metal buildings.
A Complete Metal Building Insulation System -- Requires an insulation that prevents condensation, radiant heat transfer and has an R-value that is unaffected by humidity. Given this demand, most insulations perform poorly in metal buildings.
Fiberglass Metal Building Insulation Loses R value
Once fiberglass insulation gets wet (and it will get wet, due to condensation in a metal building) it will lose R-value! Water trapped between fiberglass insulation and the exterior of the building will also cause mold, fungus growth, rust and oxidation - Conditions that will degrade the metal and shorten the service of the building. 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. Is R-value meaningless?
Spray Foam Metal Building Insulation Doesn't Stop Radiant Heat Transfer
In addition to being very expensive, spray foam insulation won't prevent radiant heat transfer (the primary source of heat-flow in and out of your metal building). Without a radiant barrier, when your metal roof gets hot (as in summer) it radiates solar-generated heat down. This often results in it being hotter in your building than out. It's also suggested you supplement open cell foam with a vapor barrier. Why not get the vapor barrier all in one product?
Bubble Wrap Metal Building Insulation Collapses in Time
If bubble insulation is punctured or smashed, its core (center) collapses. 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 suggest you order Prodex Total because of the quality of its core, if your budget only allows for bubble wrap, we suggest our single bubble insulation over double bubble. You'll get virtually all the benefits of the double bubble while saving money.
To meet the unique insulation requirements of a metal building, you need a total insulation system - Prodex Total Insulation = Radiant barrier + Reflective Insulation + Vapor barrier.
Condensation in A Metal Building - It can feel like a Rain Forest
The most reported problem by metal building owners is condensation. In addition to being a vapor barrier (perm rating less than 1), Prodex Total Insulation also eliminates condensation. When a cold surface comes in contact with warm air it creates moisture on the surface (cold bottle outside in summer).
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.
Hot In A Metal Building - Radiant Heat Transfer
Ever wonder why it's so hot and wet inside a metal building in the summer and so cold and wet in winter? 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 transfers the sun's heat into a building, and in cold weather it rapidly transfers the heat out of your building. When warm air comes in contact with the cool metal sheet, condensation occurs.
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.
Cold In A Metal Building - Colder Inside Than Out
Once metal gets cold its transfers the cold downward often making it colder inside the building that out. To combat this you need an insulation that doesn't lose its thermal protection when you need it most!
The Prodex R-value 16 is not affected by humidity. Other insulations such as fiberglass lose R-value once damp (and it will in a metal building). Once fiberglass insulation gets damp, it will stay damp. Once damp, it loses R value. Not only will you have trapped moisture in the blanket causing rot, rust, oxidation, mold etc, the damp blanket will provide less and less R value as the moisture builds. Couple this with the fact that fiberglass insulation does not prevent radiant heat transfer (primary source of heat flow) and you can see why fiberglass insulation is not the recommended insulation for metal buildings.
MORE Benefits of Prodex Total Metal Building Insulation
Protecting Contents 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 ).
Preventing 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.
Making Installation Easy
It's a lot easier and less expensive to install a 5mm roll of Prodex than a bulky 6 inch roll of fiberglass. Pinching 6 inches fiberglass between the framing and sheeting is not easy. Prodex Total can be installed before or after your metal sheeting. For fastest and easiest installation, install before applying your sheeting. Installation methods I-beam frames : Installation methods Quonset Huts
Deadening 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.
Increasing Lighting Efficiency
Prodex provides a bright, attractive finish to your building. It reflects the light, making it easier to light the building interior.
