Heat, Air and Moisture Transport Properties of Three North American Stuccos

摘要

Heat, air, and moisture transfer models that are used as practical building design tools require reliable inputs to provide meaningful results. One of these inputs is the set of heat, air, and moisture transport properties of materials. For any given class of building materials the properties may vary within a broad range. This paper reports the porosity, density, matrix density, thermal conductivity, equilibrium moisture content, water vapor permeability, water absorption coefficient, liquid diffusivity, and air permeability of regular lime stucco, regular portland cement stucco, and acrylic stucco which are commonly used in North America. The experimental and analytical procedures follow either international standards or well established methodologies.
