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.

Gutters & Downspouts

These are generally not required on steel buildings. However, use of these components often enhances the appearance of a building, control drip, splash and drainage.

Gutters and downspouts are an optional accessory that serves as trim. Gutters dramatically improve the appearance of buildings, and we recommend them for most building applications. Downspouts control the water falling from the roof, preventing the water from splashing up on the sides of the building.

On every Metal Building Depot building, die-formed ridge caps are used to cover the peak opening in the center ridge of the building. Some sellers provide a ridge roll cover that must be sealed with closures. Installing ridge roll trim is not an easy task. Over time the exposed foam closures deteriorate and there can be potential leak problems. Our die-formed ridge caps match the panel profile perfectly and are formed to fit the pitch of the roof. Die-formed ridge caps create an almost seamless transition across the roof.

Steel Building Packages

Steel building kits are shipped with all the required hardware to construct a solid structure. Forget about running around town looking for bolts or brackets with steel building packages. When investigating steel building packages, request information about the different options that are available from each steel building manufacturer. Panel material or galvalume colors can complement any building and help to exceed your expectations. You can begin with more standard steel building packages and adjust them suit your specific needs.

Working with veteran professionals is the best way to build your new steel building. Completing the steps that help you decide on different configurations for your pre-engineered building insures your ultimate satisfaction. Each part of the design process should be explained and offered for your approval. Steel building manufacturers should be acquainted with commonly asked questions and should be able to anticipate your concerns.

Other Metal Building Details

Fasteners: Self-drilling fasteners are designed for rapid drilling without slipping of the drill point, thus reducing walking and surface marring. The neoprene washer keeps your building watertight as well as providing vibration dampening.

Structural Bolts: We provide all the nuts and bolts to assemble your building through pre-punched holes.

Closure Strips: Our Steel Buildings come with closure strips which when installed provide weather tightness. The closure strips are pre-formed to match the profile of the panels.

Ridge Cap: The ridge cap is designed to match the slope and contour of the roof providing a tight seal along the ridge of the building.

Trim, Flashing, Gutters & Downspouts: All our buildings come with standard trim to give the building a finished clean look. Optional Gutters and Downspouts provide additional protection from the elements.

Plans and Drawings: We provide a full set of anchor bolt plans for the placement of anchor bolts in the foundation. We also provide engineered stamped and certified construction prints. In addition we provide an in depth erection manual to walk you through the erection of your building.

Frame Features

Connection Clips - Specially fabricated clips are designed to securely connect structural components. Many companies supply only blank plates that must be cut, drilled and/or welded to components before assembly can begin. In some cases it may require many hours of work to connect required clips. Metal Building Depot details and supplies each clip and placement to every building manufactured. We factory weld all clips onto rigid frames and guarantee the correct placement of all component connections. Don't waste your time and money attaching clips that should have been factory located.

Structural Bracing - Most buildings under 60' have sufficient diaphragm action or "panel shear" that provides all the bracing needed to stabilize the building. In some cases of high winds, seismic or snow loads may cause more stress than panel shear can handle, so additional reinforcement may be required. In these extreme cases we will employ the use of X bracing to reinforce the frame. In situations where X bracing cannot be used a wind column is an excellent addition to strengthen a vertical rigid frame column. A portal frame is sometimes used in extreme load circumstances. Portal frames are fairly expensive and only necessary in rare circumstances.
