Fiberglass Insulation Under-Performs In Metal Buildings - Condensation, Mold and Loss of R-value Problems
Solving Your Heat, Cold and Condensation Problems
Metal buildings require an insulation that doesn't just protect from the cold - It also must provide protection from radiant heat and condensation.
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 sheeting will create a drip. A temperature difference between outside and inside your building creates condensation - Similar to what happens when you leave a cold can of beer outside on a hot day.
- Heat - Mid-summer sun rays hitting the metal sheeting radiates downward (inside). It makes it unbearably hot and humid inside.
- Cold - Winter temperatures turn metal sheeting cold. The cold sheeting creates the effect of an ice box making it colder inside the building than out. This also adds to the condensation problem.
Fiberglass Insulation Loses R-value Due to Moisture In Metal Buildings
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 that 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!
Solution - Prodex Total Reflective Insulation
New Prodex Total 5M Plus - R17. 5mm (0.2") closed cell polyethylene foam covered on both sides with reflective reinforced foil facing. Roll Sizes :
New White Prodex Total 5M Plus: R15.3. 5mm (0.2") closed cell polyethylene foam with reflective reinforced foil facing on one side and plastic white finish film on the other side.
New Prodex Total 10M Plus - R22. Twice as thick as regular Prodex Total. 10mm (0.4") closed cell polyethylene foam covered on both sides with reflective reinforced foil facing.
Any metal building or pole barn that uses fiberglass insulation rather than Prodex Total will have moisture issues (typically hidden behind facing), Loss of R-value (consequence of the moisture) and heat gain.
It can feel like a Tropical Rain Forest in A Metal Building With Fiberglass
On the other hand, 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.
Fiberglass Insulation Does Not Prevent 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 insulation does not prevent 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 radiate the sun's heat into a building.
In cold weather it rapidly releases the heat out of your building. When warm air comes in contact with the cool metal sheet, condensation occurs.
