Abstract：Starting from the functional principles and current application status of waterproof vapor-permeable layers as well as vapor barriers,this paper analyzes the implications and requirements of a key performance indicator-water vapor transmission performance.Based on China's thermal design zoning,targeted design schemes are proposed for different climatic scenarios to pre-vent water vapor from infiltrating into the building envelope,thus avoiding damage to the insulation and durability of the building.
