Known as EIFS (Energy Insulation and Finish System) or synthetic stucco, this nonload bearing wall system is found on many residential homes, buildings, offices, shopping malls, hospitals, hotels, and more. EIFS is considered by industry professionals and architects to be the superior cladding product for energy conservation.

A key element of external insulation systems is that it wraps the walls with continuous insulation and a waterproof air/moisture barrier. This prevents the penetration of moisture into the building envelope, which may otherwise damage a structure and promote mold growth. It also minimizes thermal bridging and air infiltration and lowers energy consumption. EIFS also complies with NFPA 285 and other fire-resistant tests.

EIFS is an exterior cladding system that is typically applied over wood or steel studs and sheathing to provide structural integrity and moisture control. This multilayered construction consists of rigid foam insulation, a waterproofing layer, a base coat with glass fiber reinforcing mesh embedded within, and a textured finish. A drainage plane is located between the water-resistive barrier and the insulation board, which allows moisture to escape the wall without causing damage.

The flexibility of the EIFS system provides designers and builders increased creativity, architectural appeal, and aesthetics without sacrificing functionality. It is economical, easy to install, and doesn’t diminish interior square footage. Expanded polystyrene insulation can be cut or molded to create complex shapes and details like arches, keystones, cornices, columns, window details, sculptures, and more. The finishes are available in a wide variety of colors and textures.
