Proper Ventilation of a BuildingProper 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. FacingsIn 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 Thermal Conductivity (K-Value)A unit used to express the amount of heat, in BTU's per hour, that passes through one square foot of homogeneous material that is exactly one inch thick and has a temperature difference of one degree Fahrenheit between its surfaces. As the K-Value decreases, so does the amount of heat permitted to pass through the material. Thermal Conductance (C-Value)A measure of the amount of heat that passes through materials of any thickness. Recommended Installation Methods of InsulationRoof 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.
