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.

Visible Condensation

To effectively control visible condensation, it is necessary to reduce the cold surface areas where condensation may occur. It is also important to minimize the air moisture content within a building through the use of properly designed ventilating systems.

Metal Buildings

Maybe you have already purchased a small backyard storage unit. If so, you have more than likely discovered that it offers inadequate space. A custom designed metal building can still easily fit in your backyard and provide you with the space you need.

Steel buildings can be designed to your specifications; these buildings are complement to your home. Youngsters appreciate the extra space to play, practice, or hang out with their friends. If you are in need of extra space but can't afford pricey construction work, a pre-engineered metal building is the way to go.

Commercial Buildings

It is said that close to 90% of all new commercial construction is a steel building system. The ease of construction makes a new steel building system more attractive to builders and owners alike. From carwashes to skyscrapers steel has, and will continue to lead the way. Steel buildings are great for workshops or manufacturing facilities, classrooms or church buildings, metal buildings are fast replacing less adaptable building systems. Today, more than ever our world is growing faster and more competitive. Architects and professional building designers are becoming more aware of the benefits of steel from a construction and economical standpoint. As new steel building systems are introduced, we see the bottom line improving on construction projects of all kinds. The ease of construction and versatility makes a steel building attractive for a variety of uses.

Overall Heat Transmission Coefficient (U-Value)

A unit used to express heat passage through a complete building section, including air films. U-Values serve as a basis for determining transmitted heat loss. The lower the U-Value, the higher the insulation value.
