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

Proper Ventilation of a Building

Proper ventilation in a building can be an effective measure for condensation control. The end use of the building must be the controlling ventilation design parameter, especially above drop ceiling areas. Ventilation system design should be done at the initial building design stage. Use of a design professional is strongly recommended to assure the best possible system.

CONDENSATION CAN BE MINIMIZED THROUGH CONSIDERATION OF CLIMATE, RELATIVE HUMIDITY AND THICKNESS OF INSULATION.

Controlling Condensation

Two things must be present for condensation to occur: warm moist air and cool surface temperatures below the dew point. The proper control of these two factors can minimize condensation.

In metal buildings, we are concerned with two different areas or locations: visible condensation which occurs on exposed surfaces below dew point temperatures, and concealed condensation which occurs when moisture has passed through the vapor retarder and into interior roof and/or wall cavities and then condenses on a surface below dew point temperature.

Overall Heat Transmission Coefficient (U-Value)

A unit used to express heat passage through a complete building section, including air films. U-Values serve as a basis for determining transmitted heat loss. The lower the U-Value, the higher the insulation value.
