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.

Secondary Framing

Secondary framing is created from rolled steel coated with a red-oxide primer finish in gages from 12 to 16 to provide an extremely rigid, and corrosion resistant structure. The following elements are formed as secondary framing:

Girts (walls) & Purlins (roof): These members run the length of the building providing rigidity, and a sturdy skeleton to attach the sheeting. They are rolled from steel coils 12,14 or 16-gauge steel, or thicker if needed. All girts and purlins are pre-punched for ease of assembly.

Eave Struts: This is a rolled member formed into a "C" to match the pitch of the roof. The eave strut is also made of 12, 14, or 16-gauge steel.

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.

Our Commitment to Quality

Our vision is to remain the industry leader through innovative, and professionally based services and to provide trusted and practical steel building solutions at competitive prices. Years of research and development, engineering input, computer programming and superior web design have allowed us to provide to you, the most innovative, unparalleled on-line design and pricing system in the world. Organizations large and small look to us for innovative solutions - we provide you with effective solutions to manage costs and promote customer satisfaction with every building. Within the industry, we stand alone in our innovation of design and engineering procedures and our ongoing commitment to customer service. The result? Affordability and an unprecedented ability to meet your specific needs.

Independence and Integrity: How We Conduct Our Business - What we do is important, but equally important is how we do it. From the beginning, we have taken the view that keeping up with our customer's demands requires objectivity, fairness, open processes, an attitude of respect, and adherence to best design and engineering practices. And, in part because we have always been independently owned, these core values remain at the center of our business ethic. In short, we believe integrity and excellence go hand in hand and our autonomy gives us the necessary freedom to put that belief into practice every day.

Knowledge and Innovation: Why We Excel: Year after year, we pursue a rigorous agenda of pertinent, unbiased research, probing the complexities of steel design. As an independent structural fabricator, we have no hidden agenda, no conflicts of interest, and no outside "dealer network" to protect. We objectively analyze patterns of our competitor's sales tactics, and routinely adjust pricing based on current market values. We seek to understand the causes of rising costs. And, most importantly, we use what we learn as the springboard for innovation. Staying in the "technological" front enables us to develop practical, workable strategies that will assure our continued success.

Pricing Excellence: What True Customer Service Means to Us - We think our customers should derive a real benefit from our online "real time" pricing program. That's why we define great service as giving customers what they most need and want. Knowledge empowers we help customers better manage their own needs, make wiser choices and lower their costs. We understand the importance of convenience too, so we made this automated service available to you at your leisure, day in and day out. We make quoting a steel building easy through our on-line pricing system. Make no mistake about it; our system is light-years beyond anything on the market today. Building on customer input, we created a broad range of user-friendly Internet tools that deliver the unprecedented ability to self-manage the design, pricing and purchasing of a new steel building. These tools include online member areas, building-specific accessory information, lease and finance information, our proprietary password protected quote storage, and a customized secure purchase area with multiple deposit payment options including credit card, personal check, and finance options.

Quality Products: Why We Put Structural Integrity First - The reason is simple: Your safety is our highest priority. Nothing illustrates our fundamental commitment to structural integrity and quality building design more clearly than our own proprietary design system. For example, we never consider any design until it has been demonstrated on the strength of clear and convincing scientific evidence to be safe and structurally sound. While cost is an important consideration, we consider the price of a building only after its structural merit has been established. You can be sure that we build our structures around the most advanced engineering practices.

Special Order Buildings: How We Deliver Results - Quality planning planning that begins anew with each customer makes all the difference. Our design specialists know that each customer presents unique circumstances and challenges. So we customize each plan, taking into account all the variables considering the implications from every angle. We also help take the guesswork out of decision-making. Using customer-specific data, our building design team can model results based on past experience and current available options so customer decisions are always well informed. The result is a collaborative solution fine-tuned to address both the customer's need to manage costs and design considerations.

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.
