2 Don'ts When Buying Insulation For Metal Buildings
1. Don't buy insulation that loses R-value if wet. Insulation gets wet in metal buildings due to condensation
Condensation In A Metal Building
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.
Condensation Damages Contents In A Metal Building
Protect your valuable contents from damaged caused by moisture.
Using Prodex Total as your metal building or warehouse insulation will eliminate 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 reflective 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 reflective layer of Prodex metal warehouse insulation keeps the heat (heater) or cold (air-conditioning) inside the warehouse from getting to the metal skin. This also helps in preventing condensation.
Fiberglass Losing R-value And Cracking In Metal Building
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. Avoid an insulation that collects moisture, attracts mold, cracks and needs to be replaced. If you insist on using fiberglass, use it in conjunction with Prodex Total, so the Prodex can keep the moisture out of the fiberglass.
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.
We repeat! If fiberglass is used as metal building or pole barn insulation rather than Prodex Total, you'll have moisture issues (typically hidden behind facing), Loss of R-value (consequence of the moisture) and heat gain.
2. Don't buy insulation that that doesn't stop radiant heat transfer.
Radiant Heat Magnified in a Metal Building
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.
Fiberglass and spray foam don'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. Prodex Total steel building insulation solves radiant heat problems. Since open cell foam providers suggest you supplement open cell foam with a vapor barrier. Why not use a steel building insulation that includes a vapor barrier and a radiant barrier? The cheapest way to insulate a metal building is to use one product that includes everything!
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.
Your metal building insulation shouldn't only protect from cold - It also must protect from radiant heat and condensation.
Colder In A Metal Building Than Out
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.
