The substrate to which an EIFS is attached is not considered part of the EIFS. However, the substrate must be compatible with the EIFS, and be properly designed and installed for the EIFS to perform acceptably. EIFS components are shown in Figure 115.
EIFS are often applied to substrates treated with a moisture, air and/or vapour barrier. Barriers that are compatible with EIFS are provided or recommended by manufacturers. A typical EIFS arrangement with a vertical joint between panels is shown in Figure 116.
