What should the siding not be considered the only barrier to?

The siding of a building should not be considered the only barrier to water intrusion because it is just one aspect of a comprehensive moisture management system. While siding serves as the first line of defense against the elements, it is important to recognize that there are multiple layers and materials involved in preventing water from penetrating into the building. This includes the house wrap, flashing, and drainage planes, among other features.

Proper installation and maintenance of these layers are essential for effectively managing moisture and protecting the structural integrity of the home. If the siding is improperly installed or damaged, water can bypass it and lead to significant issues such as mold growth, wood rot, and damage to insulation and structural components. Therefore, relying solely on siding to prevent water intrusion does not take into account the full system of water management that should be in place.

Other options involve barriers to air, sound, and insulation, which are influenced by different construction practices and materials, making them less relevant in the context of moisture protection specifically.
