Often referred to as “synthetic stucco” (but not full-fledged concrete), an EIFS is a non-load bearing, exterior wall cladding system that consists of an insulation board attached either by adhesive or mechanically, or both, to the substrate.
The EIFS gets finished with an integrally reinforced base coat and a textured protective top coat.
There are a number of versions of EIFS. The most basic and conventional EIFS is called a “barrier EIFS” (also known as a traditional or conventional EIFS). Another type is called an “EIFS with drainage,” which is a barrier EIFS that has water drainage capability.
EIFS got introduced for commercial use in the United States in the late 1960s and later got used in residential applications.
