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.

Temperature Control

Your geographic area will, to a great extent, influence the type of insulation that will provide the best performance. If you live in a mild climate and your building is used for farm equipment storage, insulation may not be necessary. If you are planning to have employees working in a building, you should probably install insulation, particularly in areas where temperatures are extreme. Energy savings will quickly pay for insulation if the building will be climate controlled.

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.

RECREATIONAL

Todays sports, conditioning and recreational centers represent a multi-billion dollar business which continues to grow each year. Attractive, ultra-modern facilities are springing up everywhere, offering a myriad of activities to meet the recreational demands of our society.

Immense clear span, low cost-per-square-foot, and low energy costs are vital to the successful construction and operation of recreational facilities. Whether your need is for a tennis, bowling or health club facility, computerized design and manufacturing help our design engineers create building systems that meet the precise demands of recreational facilities with an eye to architectural designs that fit into any surrounding. Our engineers have designed and manufactured buildings for sports courts, sports fields, game rooms, locker rooms, roller rinks, ice rinks, riding arenas, recreational centers and every other pastime you can imagine. The most important element in the design of all these facilities was combining practicality with efficiency, while providing for the customers' needs. Equestrian buildings provide excellent examples of how the flexibility of these custom designs allow for cost-effective solutions to those specific needs. Your dealer can value-engineer a dollar-saving building system that fits the bill, whether your needs include an arena, a barn or a complete riding facility. Available from one stall to one hundred, with a center row or in a shed-row design, our value-engineered horse barns give you maximum space with a functional layout designed to streamline your horse operations. Riding arenas are available fully-enclosed or as a roof-only structure. Clear span arenas are available up to 240 feet wide and in unlimited lengths. Our engineering department and your dealer can work with you to custom design a structure which maximizes your building site with attached barns, tack rooms, or hay storage areas.

Panel Profiles

Roof Panel Profiles - Our standard roof sheeting is the "PBR" panel, which is available in bare Galvalume Plus® as well as a variety of colors. Wall sheeting is available in "R" and "PBR" panel. Depending on the color and your geographic location - PBR panels may not be available for certain colors.

Liner Panels - For liner panels we offer a low-rib 29-gauge panel. Liner panels are an interior covering for the walls of a steel building. Like exterior walls, liner panel consists of 3-foot wide panels that are attached to the framing in the same manner as exterior sheeting. Full-height liners run from floor to roof. Partial-height liners typically attach to the girt at 7'4" and extend a few inches above it. Buildings with liner panels must have a base connection for the bottom of the panel (see base conditions).

Advantages - Liner Panels enhance appearance, providing a finished look for the interior. The biggest advantage is that liners protect the insulation and the outside walls. Because un-reinforced insulation facings tear easily, and even the best-reinforced materials can be damaged, liner panels are the intelligent solution to protect your investment. Although 26-gauge exterior walls can withstand a lot of punishment, a steel liner will protect your building's interior and performs at a lower cost than other wall coverings, which will require their own framing.
