Condensation Control

The condensation process occurs when warmer moist air comes in contact with cold surfaces such as framing members, windows and other thermally conductive accessories, or the colder region within the insulation itself (if moisture has penetrated the vapor retarder). Warm air, having the ability to contain more moisture than cold air, loses that ability when it comes in contact with cooler surfaces or regions. When this happens, excessive moisture in the air is released in the form of condensation. If this moisture collects in the insulation, the insulating value is decreased.

In dealing with condensation, air may be considered to be a mixture of two gases-dry air and water vapor. One thousand cubic feet of air at 75°F can hold up to 1.4 pints of water. At 45°F, it can hold only 0.5 pints.

Relative Humidity is a percentage measurement of the amount of water vapor present in the air in relation to the amount it is capable of holding at that temperature. Therefore, 50% Relative Humidity would mean that the air is carrying only one-half of the total amount of moisture that it could be holding at that particular temperature. Cold outside air is usually much drier than warm inside air. Therefore, you can lower the Relative Humidity by bringing in outside air to mix with and dilute the moist inside air. At 100% Relative Humidity, the air is "saturated."

The temperature at which the air is saturated and can no longer hold additional moisture is called the dew point temperature. Whenever air temperature drops below its dew point, excess moisture will be released in the form of condensation. Condensation problems are most likely to occur in climates where temperatures frequently dip to 35°F or colder over an extended period of time.

Metal Frame

What is a stronger material than metal? Metal frame buildings are nearly indestructible. You can certainly feel safe in even the worst weather in a metal frame structure.

Erecting a metal frame pre engineered building might sound like a difficult project, but despite this perception, it is really not the case. Metal frame structures are cut to precise measurements and a complete set of building plans will aid in the assembly process.

If you need help constructing your metal building, you will incur additional expenses, so be sure to factor construction cost into your budget when purchasing a steel building.

Before you Buy

Do you know the company you're doing business with? Is the supplier a member of the Better Business Bureau? Do they have a record of dealing honestly? Can they refer you to satisfied customers? Is the physical address to the company available? Can you visit them at their offices? Are they a real company with a history of quality manufacturing? Are they Active Members of the AISC (American Institute of Steel Construction) Do they post any affiliation with any steel building association? Do you know what you are paying for? Does the steel building contract give line-item prices? Will you receive comprehensive set of erection plans? Are you getting written 30-year paint and 25-year Galvalume Plus® warranties? Does the contract specify 26 gauge panels? Does their roof panels include a "purlin bearing" leg? Does the roof system have an Underwriters Laboratories Class 90 rating? Are you being supplied with premium fasteners with a lifetime red-rust warranty? Will your steel building have a sculptured trim package? Are all the clips welded to primary structural components? Are the framed openings factory located? Does the supplier have the ability to engineer a custom design? Will you receive an 80+ page fully illustrated erection manual? Does the supplier have an in-house customer service department? Does the supplier actually manufacture what they sell? Do they process and produce all their drawings in-house? Do they ask you to sign a contract and pay a deposit before you know the total cost?

Foundations

Do I need a foundation for my metal building? - Some people choose to pour a full slab foundation, however if you're planning on leaving the floor in a dirt or gravel condition, concrete piers will do the job just fine. Please contact a customer service representative if you don't plan to pour a full slab foundation.

Can you provide an engineer stamped foundation layout? - Yes, but in some cases your soil conditions play a major role in the type of foundation you can use. Contact our special sales department for more information. If using a local engineer, we will provide anchor bolt plans to aid your engineer in designing the foundation.

Do you supply the hardware to attach the frame to foundation? - No, the anchor bolts are usually supplied by a concrete contractor and placed when the foundation is poured.
