Traditional stucco and EIFS (Exterior Insulation and Finish System) may look the same at first glance. However, these two types of exterior cladding serve different purposes and have many key differences. 

First: exterior cladding is a broad term for the outer layer of a building. This layer can be made up of many different materials: brick, wood, specialty siding, stucco, plaster, or EIFS. Oaks Brothers Inc is a commercial exterior contractor with decades of skill, knowledge, and experience.

What are Stucco & EIFS?

Stucco 

Stucco is traditionally made from sand, lime and/or Portland cement, and water. This mixture can be tailored to the needs of the building — more cement makes it durable, while more lime makes it moldable. Some versions incorporate glass fibers or acrylics for added strength. In terms of aesthetics, stucco provides a variety of options: it can be smoothed or textured, and pigment can be added for a range of finish options. 

EIFS

EIFS is sometimes referred to as synthetic stucco, but that’s not an accurate term. It’s not a synthetic version of stucco, it’s an entirely different system. EIFS consists of layers that protect the building and create a high = performance shell, or building envelope. The layers include a water resistant barrier, an insulation board typically made of polystyrene foam, a reinforced base coat made of polymer-modified cement, and a finish coat that is both protective and decorative. 

How Do EIFS and Stucco Compare? 

Both materials offer design versatility and exceptional durability — which makes the choice hard when picking between the two. Here’s where these two materials differ: 

Cost 

On average, stucco is slightly less expensive than EIFS up front. However, this very much depends on the scope and complexity of your project. And, stucco refers to just the exterior cladding, while EIFS offers insulation properties around the exterior of your building as well. Stucco generally requires a separate insulation product to be installed underneath. 

Maintenance

Both stucco and EIFS will show dirt and need to be cleaned regularly. Beyond that, EIFS generally has a lower maintenance cost over time as its flexibility makes it resistant to cracking, and it’s designed to withstand moisture. 

Stucco is a rigid material that can crack and settle, or deteriorate over time due to temperature changes. In addition, moisture can enter these cracks, and weaken the structure and finish.    

Energy Efficiency 

Traditional Stucco offers minimal insulation properties, with an R-value of .2 per inch. EIFS, on the other hand, is designed to be energy efficient and provides an R-value of up to 6.5 per inch. EIFS can reduce a building’s energy usage by up to 45%.  

Appearance 

Stucco offers a traditional look, and can be finished in multiple different textures including smooth, which is even and regular, sand, which has a lightly pebbled texture, dash, which is rougher and more pronounced than sand, and Santa Bardara, which is smooth but slightly irregular to give a rustic look. 

EIFS offers more versatility. Its lightweight and flexible composition means it can be molded into nearly any shape for intricate architectural details like arches and columns. It can also mimic other exterior cladding styles, providing a finished look that matches your architectural designs whether it’s wood, brick, limestone, or other materials. 

EIFS and Stucco for Commercial Construction 

Either EIFS or Stucco may be the right choice for your commercial construction projects. Neither is a one-size-fits-all solution, but both stucco and EIFS have their benefits.

EIFS is an excellent choice for large-scale construction projects. Its ease of installation and flexibility for new construction or retrofit projects make it a clear logistical choice. Beyond that, its energy efficiency and fire resistance mean it adheres to strict building codes and can provide a long-term cost benefit as it significantly reduces energy consumption. 

Stucco, while less insulating, provides inherent fireproofing properties. It’s also very strong and durable. Though it can crack, with proper maintenance over time, it will last for decades. Finally, its traditional look and rustic texture is often sought-after, especially in historic communities and the Southwest U.S.
