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.

Recommended Installation Methods of Insulation

Roof insulation rolls are cut to lengths that will cover the distance from eave to eave, leaving a one-foot overhang on each side of the building.

1) Start at the end of the building and temporarily secure one end of the roll by attaching the insulation to the eave strut with double-faced tape.

2) Pull the insulation across the purlins with the vapor barrier toward the building interior. Double-faced tape attached to the opposite end of the insulation will keep tension on the roof roll while the metal panels are being attached over the insulation.

3) Install the next roll in the same manner, making sure the rolls are stretched tight, aligned properly and closely butted.

4) Fasten tabs using one of the methods described on the following page. Any rips or tears must be covered with matching facing tape to ensure a tight vapor seal.

5) Trim excess insulation flush to prevent it from acting as a wick and moving water into the building.

COMMERCIAL OFFICES

Your place of business should and can be more than just a place to work. It should reflect your company's image and be no less comfortable, functional or attractive than your living environment. Entry-ways and lighting, interior wall placement, and location of restrooms are as important in your office building as they are in your own home. Properly planned, your facility will serve your needs for many years to come, and you will avoid future changes or costly remodeling.

Modern ceiling and interior wall systems are very easily adapted to our manufactured building components using standard methods. For instance, perimeter sheet rock walls may be installed by simply attaching metal furring strips (hat channel) to the secondary wall framing members (girts). Similarly, acoustic panel or dry-wall ceilings may be installed by simply wrapping the ceiling suspension wires around the secondary roof framing members (purlins). Additionally, port-a-wall systems may be installed as needed throughout the structure.

Additional loads from heating and air conditioning systems, dropped ceilings, electrical conduit and lighting fixtures, or large mechanical sprinkler systems can be accommodated easily at your request with minimal cost, assuring a full roof-load certification.

The building components may represent a small percentage of the total cost of your office budget. Therefore, we are careful to ensure that the main structural components we provide will be reliable, helping to protect your investment against any water seepage, leaks or storm damage that can deteriorate your office complex.

When selecting the manufacturer of your building components, careful consideration must be given to both function and price. Your dealer will encourage you to have an architect review all aspects of your building plan, including lighting requirements, window heights, storage space, carpet wear ability, entrances, landscaping, parking and signage, to ensure you of a facility that will maintain its value and be a source of pride for years to come.

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.

Benefits Of Pre Fabricated Metal Buildings

Reasons people choose one thing in place of another are normally are obvious and easy to recognize. Choosing the right kind of steel building system can be a little more difficult. All pre-fabricated metal buildings are not created equal. There are many elements of design and customization that make them very different and the differences are not always obvious. Please brows our preferred vendor listings. There you can find in-depth information about many quality-building suppliers.

Regardless of your intended purpose, whether to store equipment or use as a metal shop building, pre fabricated steel structures offer many advantages. Insulation and temperature control options and extras like customized paneling and many color choices add uniqueness and style.

The main advantage of a pre fabricated metal building is its simple assembly. Steel Buildings are shipped complete with all the accessories and hardware needed for construction. In many cases, you could have a steel building delivered and erected before most conventional builders could complete the initial planning.

To learn more about the benefits of pre fabricated metal buildings, contact a manufacturer. Along with a price quote, they can give you an idea of the customization options and floor plan styles available. Top companies provide the advice of skilled professionals to assess your needs to match you with the right building.
