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.

Insulating Against Radiant Heat

Traditional forms of mass insulation, like fiberglass, are effective in preventing heat transfer by conduction and convection, but they less effect on radiant heat. Between 80 and 90% of the radiant heat striking fiberglass will pass through or be "emitted". Radiant transfer typically has as much impact on the temperature in a building as conduction and convection. For more information on radiant barrier facings click here.

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.

Frame Types

Unlike any of our competitors, we allow you to price all building frame types. Select from Clear-span or Modular rigid-frame buildings. We allow you the full flexibility to choose Gable, Single Sloped or Offset Peak building shape. By far, we offer the widest selection of building and frame types. For options not available through the online system, you will need to request a special quote.

Clear-span Frames - A clear-span rigid frame offers strength and economy. Since no interior supports are necessary, this design is best when you require large areas of clear and uninterrupted space. Factories, warehouses and agricultural buildings are just a few building types that may utilize a clear-span frame building. A clear-span design does have size limitations. As the desired width increases, the frames will become larger and heavier to carry greater loads across the length of the frame. At some point the cost will outweigh the benefit. Even so, clear-span buildings are still effective for buildings as wide as 150' feet and wider in some cases.

Modular Frames - Modular frames use interior columns to evenly distribute the load; reducing the cost of both the frame and foundation of extra wide buildings. The economical advantages become obvious when a building width is about 100' wide or wider. As a result, almost all buildings 100' wide or wider have interior support columns. Modular designs are often used for large factories and warehouses.

Single Slope Frames - Single slope frames have high and low eave heights creating a roof that "slopes" from side to side. To select a single slope design, you specify one eave height and define the roof pitch. Single slope designs are frequently used for strip shopping centers, offices, and RV/Boat storage facilities.

Just about every steel building has at least one framed opening. It is not unusual for buildings to have several openings. Most openings are created for an overhead door, but can be used for the installation of glass fronts or other entries. Most other online sellers offer "field located" framed openings, which require cutting and fabricating on the job site. Metal Building Depot always provides factory-located openings unless your project requires something otherwise.

Storage Building Plans

No architect or engineer is required to read steel building plans. Although they are technical, they are created so anyone can easily comprehend them. When your steel building package arrives, you will find a wealth of useful information and instructions on building installation. Storage building plans for steel storage buildings show common construction details. The floor plan is displayed so you know what, and in which order to do each task. If you have any difficulties, your steel building manufacturer can easily explain the process.

Another important thing you should remember is, since you are an integral part of the building design phase, you should be very familiar with the basic floor plan. But, if you need assistance with building plans, your supplier should explain the layout in a manner more complimentary to your way of thinking.
