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.

Steel Frame

Metal buildings are strong. It is the nature of their design. Because they are built to survive the harshest conditions, you can rest assured that you investment will last for years to come. The basic design provides great structural stability, even in an earthquake or windstorm. The rigid steel frame reinforces the secondary structural framing system. Any building is only as good as its foundation. A steel frame is the ultimate starting point for your building.

The last thing you need to worry about is the structural integrity of your office, shop or storage buildings. An advantage with pre-engineered buildings is there are no roof shingles for you to worry about replacing later. A smart investment is one that requires the least amount of cost now and in the future. Steel frame buildings are just such an investment.

Wall Installation

Labels on wall insulation rolls indicate the length as well as the number of pieces that need to be cut from each roll. We recommend that all rolls be cut from a clean location to avoid staining the insulation facing.

1) Cut the dimensions of the insulation from the base angle to eave strut or rake plus 6"-12" extra.

2) Attach one end of the insulation to the base angle using double-faced tape.

3) Pull from the other end to stretch the insulation tightly outside the girts to the eave or rake, and attach with double-faced tape.

4) Make sure the facing is toward the interior of the building and attach the panel to the structure.

5) Install the next roll in the same manner, with edges butted snugly. Then fasten the tabs using one of the methods described.

Recommended Installation Methods of Insulation

Roof insulation rolls are cut to lengths that will cover the distance from eave to eave, leaving a one-foot overhang on each side of the building.

1) Start at the end of the building and temporarily secure one end of the roll by attaching the insulation to the eave strut with double-faced tape.

2) Pull the insulation across the purlins with the vapor barrier toward the building interior. Double-faced tape attached to the opposite end of the insulation will keep tension on the roof roll while the metal panels are being attached over the insulation.

3) Install the next roll in the same manner, making sure the rolls are stretched tight, aligned properly and closely butted.

4) Fasten tabs using one of the methods described on the following page. Any rips or tears must be covered with matching facing tape to ensure a tight vapor seal.

5) Trim excess insulation flush to prevent it from acting as a wick and moving water into the building.
