Evaluation of Water-Resistive Barrier Performance in Stucco Walls ✓ Most Recent

This paper describes the results of a detailed laboratory evaluation and field demonstration of innovative residential building assemblies and construction practices intended to reduce the risk of moisture penetration and mold growth in walls with stucco cladding. Laboratory experiments and field demonstrations of water-resistive barrier (WRB) options in stucco walls are reviewed, with special focus on window installation methods and insulated wall assemblies subjected to moisture loading conditions. Additional laboratory evaluations, as well as consensus performance and prescriptive standards supported by field data and validated models, are recommended.
