One of the cornerstones of the EIFS Industry Members Association is the research on EIFS and the exterior wall that is initiated and sponsored by EIMA. In this section you will find information on EIMA's landmark research on the hygrothermal performance of EIFS and competing wall claddings. Phase III of this ongoing project will take the results of Phases I and II and, through simulation, demonstrate how they apply in all U.S. climatic zones.
