Which of the following statements is true about EIFS siding?

EIFS (Exterior Insulation and Finish System) siding is often referred to as "synthetic stucco." This is because it provides a similar aesthetic appearance to traditional stucco while utilizing modern materials and techniques. EIFS is composed of multiple layers, including an insulation board, a base coat, and a finish coat, allowing for enhanced energy efficiency and design versatility. The term "synthetic" highlights that while it mimics the look of traditional stucco, it is fundamentally made from materials that are not typically found in traditional stucco applications.

While the other options describe different types of materials or installation methods, they do not accurately characterize EIFS siding. For instance, fiberboard is a type of engineered wood product used in various applications but is distinct from EIFS. The idea that EIFS comes in rolls or is easy for a homeowner to apply isn't accurate either, as its installation is complex and usually requires professional expertise to ensure durability and proper insulation. Thus, recognizing that EIFS is indeed a synthetic stucco provides clarity on its function and application in modern construction.
