Controlling Condensation

Two things must be present for condensation to occur: warm moist air and cool surface temperatures below the dew point. The proper control of these two factors can minimize condensation.

In metal buildings, we are concerned with two different areas or locations: visible condensation which occurs on exposed surfaces below dew point temperatures, and concealed condensation which occurs when moisture has passed through the vapor retarder and into interior roof and/or wall cavities and then condenses on a surface below dew point temperature.

Storage Buildings

It almost appears that almost every, home and garage is bursting at the seams. Surplus or unneeded equipment, furniture or other belongings clutter closets, attics and garages. But, the option of monthly storage fees does seem like a hefty price to pay just to hold on to the things you have.

Self-storage buildings are an easy way to put your money in someone else's pocket. Holiday decorations, childhood keepsakes and files all need to be retained for different reasons, but the cost of storage is a burden. Owning your own storage buildings is one way to lessen the expense of personal storage with a one-time quality investment.

The exciting thing about steel frame storage buildings is that you only buy them once. Mini storage is not as friendly you pay and pay, but you never own anything but the contents you placed in them. You may think that you don't need something as permanent as owning a personal storage building. But think about it - when are you going to let go of the things you have decided to save?

Facings as Vapor Barriers

The main function of facings is to act as a vapor barrier. While a vapor barrier may not necessarily be able to stop the flow of water vapor, it does an excellent job of minimizing the rate and volume of the flow. This prevents moisture from accumulating within the insulation blanket and the structure, which translates into consistent thermal values and lower heating and cooling costs.

Facings intended to serve as vapor barriers should be installed on the inner, heated surface of the insulation, where vapor pressure is the highest. This helps in preventing vapor from reaching the cooler air and condensing.

VAPOR BARRIERS PREVENT VAPOR FROM REACHING COOLER AIR AND CONDENSING.

Surface Air Film Coefficient (F)

The amount of heat flow in BTU's per square foot per hour between an exposed surface of a material and the adjacent air. It is the measure of the conductance of heat through the air film that clings to all surfaces.

On The Farm

I don't know of any farm operation that could get buy without barns for equipment storage, feed storage or any other general warehousing needs. Many older farms are now removing old wooden structures and replacing their old buildings with new steel structures. While the old antique tractor may look good in front of the old barn, many are weary of storing precious items in an old rotten structure. Steel is stronger, straighter and will last eons longer than wood. In a home, wood is fine. Houses are designed so that the wooden structural components do not have direct exposure to the elements, but on the farm it is often hard to prevent the outside from coming into the barn.
