EIFS Testing
Exterior Wall Cladding Performance Study
EIFS Outperform other Exterior Wall Claddings such as Brick, Stucco and Cementitious Fiberboard Siding
The U.S. Department of Energy (DOE) through the Office of Energy Efficiency and Renewable Energy's (EERE) Building Technologies Program, and the EIFS Industry Members Association (EIMA) sponsored a study on energy efficiency and moisture control which was conducted by researchers at the Oak Ridge National Laboratory. The results of the landmark study provide for the first time ample real-world data demonstrating that EIFS clad wall assemblies with drainage (EIFS) outperform other typical U.S. exterior claddings (brick, stucco, cementitious fiberboard siding) during most of the year. The results also demonstrate that EIFS is an excellent exterior cladding choice for achieving key building performance goals in a hot and humid climate, specifically a mixed, coastal, Zone 3 climate.
