What is the most common type of Exterior Insulation and Finish System (EIFS)?

The most common type of Exterior Insulation and Finish System (EIFS) is the Barrier or face-seal PB-EIFS. This type of system utilizes a continuous layer of insulation on the exterior of a building, covered by a weather-resistant finish. It relies on a face-sealed approach, where moisture is intended to be diverted away from the building structure.

The popularity of Barrier EIFS arises from its ability to provide energy efficiency while allowing for creative architectural design. Additionally, this system is well-regarded for simplifying installation processes and reducing construction costs. It effectively integrates both insulation and aesthetic finishes, making it a preferred choice for many residential and commercial applications.

While other types of EIFS, such as drainage EIFS, are gaining traction due to their advantages in moisture management, barrier systems remain the most widely used in the industry. This is primarily due to their established track record, ease of installation, and the wide variety of design options they afford.
