What does EIFS stand for?

EIFS stands for Exterior Insulation and Finish System. This term refers to a type of building exterior wall system that provides insulation and a finished surface in a single application. EIFS is widely used in commercial and residential construction due to its energy efficiency, versatility in design, and aesthetic options.

The system typically consists of an insulation board that is attached to the exterior wall sheathing, followed by a base coat and reinforcing mesh, and a finish coat that offers weather protection and color. This method improves thermal efficiency by reducing air leaks and increasing insulation performance.

Understanding EIFS is crucial for building inspectors as they must assess the installation, maintenance, and performance standards of such systems to ensure they meet building codes and address potential moisture infiltration issues.
