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.

Perm Rating

The perm rating, or permeance, is a measure of the amount of water that passes through one square foot of material per hour. The lower the perm rating, the more effective the barrier. A facing material with a perm rating of 0.1 or less is considered excellent. Anything with a rating above 1.0 is not considered a vapor barrier.

Metal Buildings for Retail

Every retailer knows the importance of the manner in which merchandise is housed and displayed. In the highly competitive arena of retail sales, appearance can make a tremendous impact on attracting customers and influencing purchasing decisions.

Your retail facility can be enhanced with decorative brick, wood, stucco, glass, aggregate panels, landscaping and signage. A Metal Building Depot Acceptance Corporation dealer can help you with efficient designs and a more delightful appearance, yet stay within your budget.

Strip malls throughout the nation are being built with steel, utilizing the ability to add on or incorporate other fascia items - representing savings of up to 30% over other conventional construction methods. Owners and developers have come to realize that the pace at which a steel building system can be designed, manufactured, delivered and completed, is measurably less than that of any type of conventional construction. The short completion time and overall durability of steel building systems assure a more efficient turnkey project, as well as a quick return on the initial investment.

Thermal Conductance (C-Value)

A measure of the amount of heat that passes through materials of any thickness.

Concealed Condensation

Concealed condensation is the most difficult to deal with and can be the most damaging to any kind of structure. This type of condensation may be controlled in metal buildings by the proper ventilation. Additional condensation control can be accomplished by venting the cold cavities of the walls and roof.
