What does EIFS stand for in construction?

EIFS stands for Exterior Insulation and Finish Systems. This term refers to a type of exterior wall cladding system that provides both insulation and a finished surface in a single application. EIFS consists of insulation boards that are applied over a structural wall, typically followed by a base coat and a finish coat. This combination effectively enhances energy efficiency, improves thermal performance, and offers a variety of aesthetic finishes.

The choice of "Exterior Insulation and Finish Systems" accurately describes the system's primary function—protecting the building envelope while providing insulation. The other options do not reflect the specific terminology and function associated with EIFS; they either mix concepts or do not correspond to recognized industry standards related to insulation and finishing in construction. For example, concepts like energy efficiency and foundation solutions are too broad and not specific to the unique features of EIFS.
