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.

Facings

In addition to acting as a decorative protection barrier, facings serve an integral part of the overall insulation system. Facings provide vapor barriers, light reflectivity and structural strength. In some cases, a reinforcement of fiberglass scrim is used for extra rigidity and greater impact resistance.

The effectiveness of a vapor barrier depends on three primary factors:

1) Location within the insulated section

2) Permeance

3) Proper installation

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.

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.

Steel Buildings

Why should I build with steel instead of wood? - The number one reason is strength. Steel buildings can withstand high load conditions. Steel buildings are fastened together with high-strength bolts and screws. The connections remain secure because there is little to no movement in the structural members and panels. However, wood connections in conventional construction become loose due to expansion and contraction and the result is warping of the wooden frame. Steel does not warp, shrink, or change with time so the connections remain secure. Wooden buildings can suffer damage do to insects such as termites, and this deterioration will reduce the quality of wooden buildings. Furthermore, metal building material is not a flammable substance so your insurance costs will be reduced.

How does the price of a steel building compare with others? - Conventional construction materials are affected by demand and availability; conversely, steel has remained relatively constant for many years. When it comes to pre-fabricated steel buildings it would be difficult to find a like structure to compare with the low cost of a steel building.

Is everything I need to construct my building included? - Everything you need to construct your new metal building will be included with the exception of the anchor bolts, which should be supplied by your foundation contractor.

What is Bay Spacing? - It is the space between 2 frames. For example, the end wall of the building is the End-Frame, and the distance between the End-Frame and the next column/rafter section is the Bay Space, or the distance between two column/rafter sections.

How do I assemble my steel building? - Steel building assembly couldn't be easier. We provide you with the necessary information to erect your steel building quickly and efficiently. Many of our clients erect their steel buildings on their own, although a professional contractor can also used at an affordable price.

Are the steel buildings painted? - Yes, the walls and trim are painted with a long-lasting factory-applied paint manufactured by a leading manufacturer of heavy duty, high performance protective coatings for steel building components. There is a wide selection of colors for you to choose from. You can select the wall panel, trim, and roof colors on the color chart section of our website.
