Sky Lights

One of the most popular options available for metal buildings is a skylight. High quality translucent panels are an available option to any building. Skylights allow a great deal of light into a building. An adequate number of skylights will provide enough illumination for daytime work in a building, without the need for additional lighting. A standard configuration is to put two skylights per bay.

Metal Building Kit

Purchasing your new metal building kit. You should be cautious when buying a metal building kit. Not every manufacturer uses high quality materials or fabricates to the latest industry standards. You don't want to purchase a building from a manufacturer (or broker) whose building parts were produced in a factory without the benefit of a skilled eye to oversee the process.

A pre-engineered metal building should come with a complete and comprehensive set of blueprints. When a qualified steel building manufacturer puts its seal of approval on your building design you can rest assured of its structural integrity. You can expect detailed documentation about the building's fabrication and its specific code requirements as well.

Before you purchase a metal building kit you should attempt to create a basic plan for its end use and design. Working with a professional steel building company should ensure that all facets of your building are taken into consideration. They can explain the building options and codes in detail so you have the accurate building specifications.

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.

Surface Air Film Coefficient (F)

The amount of heat flow in BTU's per square foot per hour between an exposed surface of a material and the adjacent air. It is the measure of the conductance of heat through the air film that clings to all surfaces.
