Are You Confused by the Difference Between Stucco and EIFS?

Many people view two entirely different cladding systems, stucco and EIFS, as the same.  It is true that on the surface, these appear to be similar. But what is going on beneath the outer layer is the difference.

Stucco is a durable and attractive exterior coating for buildings and homes. The material may be applied over wood, steel, or masonry subsurfaces to provide an distinct and beautiful appearance. Stucco offers a truly classic look and requires very little maintenance.

EIFS (Exterior Insulation and Finish Systems) is a far more involved technology than a pure cladding. It is a technologically advanced and improved system to minimize energy costs while providing attractiveness with durability. EIFS consists of integrated composite layers that start with the interior subsurface and build out to a textured finished coating that may look like a stucco application.

More About Stucco

Stucco has withstood the test of time for centuries. Classic examples of the incomparable beauty and charming style of stucco remain throughout Europe and North America today.  The popular Italian Style (1890-1935) of architecture promoted stucco as the essential cladding for buildings constructed in this mode.

The development of Portland cement as the binder in stucco in the mid-1800s ignited the spread of stucco coverings throughout Europe, North America, and South America during the twentieth century. In the United States, it is rare to drive through an upscale neighborhood without seeing several homes with stucco cladding.

How is EIFS Constructed?

Starting with the interior substrate, the first component is the foam insulation board that is attached to the inner subsurface with an adhesive. Next, an acrylic or polymer-based material is applied over the insulation board as a base coat. A heavy-duty reinforcement mesh is then applied to the adhesive-covered insulation. The mesh is intended to create a uniform support within the walls, spreading any outside forces evenly throughout the structure.

A moisture drainage gap is created by inserting building paper between layers that will crinkle and disappear over time. This cavity allows any penetrating moisture to drain and escape though flashing systems or weep screed below.

The final step is the application of a textured finish coat of crack-resistant acrylic copolymer material. While the coating looks much like stucco, it is less brittle and can withstand building shifts and settling better than other claddings.
