What is the purpose of a water-resistant barrier on exterior walls?

To insulate the wall
To prevent water infiltration
To provide structural support
To enhance aesthetic appearance

The correct answer is: To prevent water infiltration

The primary purpose of a water-resistant barrier on exterior walls is to prevent water infiltration. This barrier acts as a protective layer that keeps moisture from penetrating the wall assembly, which can lead to various issues like mold growth, wood rot, and deterioration of structural materials. By effectively blocking water from entering the walls, the water-resistant barrier helps maintain the integrity and longevity of the building. Though insulation and structural support are essential components of wall assemblies, they serve different functions. Insulation is meant to regulate temperature and energy efficiency, while structural support is focused on holding up the building. Enhancing aesthetic appearance is also important, but it is not the primary function of a water-resistant barrier, which is specifically designed to keep water and moisture at bay to protect the structural health of the building.
