PUBLIC and CHURCH

Serving the building needs of America's churches, schools and local, state or federal government is a challenge. A church in Tennessee (above) employs a 60-foot clearspan structure with a specially designed hip-roof to accommodate a spacious open sanctuary. Wood and drywall were used to cover the massive steel beams that meet in the center and support the heavy, built-up roof system. Outside, the application of brick gives the feeling of strength and permanence.

Advantages of Metal Buildings

LOW COST - Our steel buildings are more economical than conventional methods due to the originating costs and reduced labor. Complete steel buildings are delivered to the jobsite and quickly erected. QUICK CONSTRUCTION - On average, a steel building system can be completed in approximately two-thirds the time required for conventional construction. BETTER APPEARANCE - The appearance of steel buildings can easily be enhanced with stucco, stone, brick or glass. Metal building systems can attain a remarkable exterior that will merge with the ambiance of the building's surroundings. LOW ENERGY CONSUMPTION - A suitably insulated metal building can drastically decrease heating and cooling expenses. Insulated roof and wall systems preserve and reassure thermal efficiencies. LOW MAINTENANCE - Extended life materials reduce maintenance, and eliminate troubles such as structural deterioration, rotting and insect damage. EXPANDIBILTY - It is easy to enlarge a building by removing the end walls, erecting new framework and adding matching wall and roof panels. In most situations, the original end wall panels can be reused.

Steel Buildings vs. Conventional Construction

A great advantage of pre-engineered buildings is that they can be relocated if required. Since your building is shipped to you with a complete set of instructions, detailed engineering drawings and a shipping list, you can erect you steel building without consulting a construction company. This also means that should you someday decide to relocate, you can take down your building and erect it elsewhere.

Adding partition walls in a steel building allows one building to be a meeting room, or office and storage facility and another to be a restaurant. Building with steel gives you the ultimate in design flexibility. You can either own one outright or purchase a steel building to rent to others. Your one time cost is regained sooner rather than later when you rent it as mini storage or public meeting space. Steel buildings can be designed with a almost unlimited amount of options.

If you have a need for a new building, don't make a decision until you have explored your options with a qualified steel building manufacturer. The Steel Building Network has reviewed a wide range of manufacturers, suppliers and building industry professionals, and we know that no matter what your intended use, there is steel building system to suit your needs. Getting I contact with the right company to get your questions answered is the first step in having your building needs met.

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.

Heat Transfer

Effectively controlling temperature in a steel building requires insulation to be present along exterior walls and roof. When a temperature differential is present in an enclosed steel building, heat will work from warmer areas to colder areas until the temperature in the building has stabilized. At the point of thermal stabilization, the cooler (and heavier) air will be present at lower elevations and warmer air will be present at the roofline. The function of insulation is to help stabilize air temperature at more desirable levels. When it is hot outside, preventing heat from transferring into the building is the goal, and of course in the winter we want heat to remain inside.

Heat transfer occurs in three ways:

Conduction : Occurs in a solid or liquid when heat from one object is transferred by touch to another object. An example of this occurs when a pot on a stove will heat up by conductive heat transfer from an electric coil.

Convection : Occurs with the physical movement of air. There are two types of convectional heat movement. The first is natural, where hot air rises displacing the cold air and moving it down. The second type is forced or mechanical convection. This occurs when an object, like a fan, physically moves or "forces" the air to move.

Radiation : Occurs when an object is warmer or hotter than the air around it. For example, the sun, which is hotter than everything around it, radiates heat waves that travel through the air and is either absorbed by or reflected by the surface it comes in contact with.
