A comprehensive assessment of the state-of-the-art of water vapor control for modern, code-compliant, light-frame wall assemblies. The primary goal of this effort is to evaluate and reconcile existing building science knowledge and practices. An important secondary goal is to support the development of practical and comprehensive water vapor control requirements or recommendations that may be used as a basis to reach various audiences and serve multiple purposes, including building industry education and building code development. (See ASTM STP1599 for additional information.)
