North Carolina Building Contractor License Practice Exam

Which of the following is a requirement for the high points of framed walls in a building?

1. Must be waterproof

2. Must be insulated

3. Must be reinforced

4. Must be capped with sheathing

The correct answer is: Must be capped with sheathing

Capping the high points of framed walls with sheathing is essential for several reasons related to the structural integrity and moisture management of the building. Sheathing serves as a critical component in construction, providing structural support, bracing the walls against lateral forces, and enhancing the overall stability of the structure. Moreover, it acts as a protective barrier, helping to minimize the potential for moisture infiltration, which can lead to issues such as mold growth and wood rot. In the context of building practices, the high points of framed walls are particularly vulnerable to environmental elements, making it important to ensure they are properly capped. This capping with sheathing also creates a level surface for the subsequent application of siding or other exterior finishes, which further aids in waterproofing and insulation aspects by ensuring a tight seal at the wall's apex. On the other hand, while waterproofing, insulation, and reinforcement are important elements in a building’s overall construction strategy, they are not specifically required at the high points of framed walls in the same way that sheathing capping is. Capping with sheathing is a standard building practice that addresses multiple concerns related to structural integrity and environmental protection, emphasizing its necessity in construction protocols.
