AbstractThis paper presents results from an ongoing program of research investigating the performance of water-managed direct~applied finish system (DEFS) and exterior insulation and finish system (EIFS) wall c1addings. These wall claddings incorporate water management into their design by combining the use of a sheathing membrane with flashing and weeps to direct any incidental intruding Water out of the cladding. These systems are designed around a rainscreen principle. Rainscreen designs assume that some water will penetrate beyond the exterior face of the wall that must be removed by a second line of defense. The water-managed DEFS and EIFS systems provide the opportunity to combine a "stucco look" architectural style with traditional wall cladding water-managementfeatures.
