HomeAdvisor lists that there are benefits to both Synthetic and Traditional Stucco siding.
“Synthetic stucco siding was developed in postwar Europe as a way to patch walls. When builders realized how energy efficient the material was, it was soon used as an alternative to traditional stucco. Because of this, in the 1970s energy crisis it became widely popular. Because of the multiple layering, EIFS is a better insulator than traditional stucco siding. It is also more flexible, allowing ornate keystones, cornerstones and other accents that traditional stucco previously could not hold. And unlike poorly installed traditional stucco, synthetic stucco does not yellow or fade, which occasionally forces homeowners to paint over their stucco.”
“The benefits of traditional stucco come in wetter conditions, as it is less likely to absorb water (and be damaged by it) than synthetic stucco siding. Similarly, synthetic stucco is a lighter material. Traditional stucco siding will hold up better to dings, hail, and woodpeckers. And while EIFS is more energy efficient, it is a small matter of degree. Both will be fire resistant, a great barrier to sound and the elements, and both come in a variety of styles and colors.
EIFS is slightly more expensive but the difference in cost is minimal. The benefits of each are best weighed for your own personal need. If you live in a wet area, or have children who like to hit golf balls against your home’s walls, you might consider traditional stucco. If you want to use stucco for ornate design, or are concerned about energy efficiency, you might consider synthetic.”
We have owned 3 synthetic stucco homes, have never had any issues, and will continue to build another one!!
