Fireblocking is required in walls over what height?

1. 6 feet

2. 8 feet

3. 10 feet

4. 12 feet

The correct answer is: 10 feet

Fireblocking is a crucial safety measure in construction that helps to slow the spread of fire and smoke within a building. According to the North Carolina Building Code, fireblocking is required in walls that exceed a certain height to minimize the risk associated with fire travel through concealed spaces, such as wall cavities. When a wall rises above 10 feet, the potential for fire to travel through additional vertical openings increases. This is why fireblocking is mandated for walls over this height. The blocks create barriers that interrupt the pathways fire might take, which can significantly enhance the safety of the structure and its occupants. In this case, the requirement is set at 10 feet, which aligns with the standard fire safety practices and building codes to ensure that structures are built with sufficient precautions against fire hazards.
