Controlling Water Vapor
This chapter discusses various measures one can take to control water vapor and indicates that water vapor is of interest to the detailer because of the issues that it can create if it condenses on or within building components. A building's mechanical system is often designed to decrease the amount of water vapor inside a building by ventilation, by dehumidifying the air with an air?conditioning system, or both. In warm and humid locations, interior air pressure should be slightly higher than outside to reduce the inflow of humid air. To block condensation, surfaces inside a building's thermal envelope should be detailed so that their temperatures will always remain above the dew point temperature of the air. In many climates, a vapor retarder sheet should be installed on the warm side of any insulating material to prevent condensation of moisture within the assembly. Water vapor must be given an easy escape route from the cold side of any vapor retarder. Where condensation may occur within a building, one must provide channels and weep holes that allow gravity to remove the moisture without damage to the building.
