Fireblocking is required if a wall exceeds which height?

Fireblocking is a crucial component in building construction, especially when it comes to preventing the spread of fire and smoke within walls. In North Carolina, as in many other jurisdictions, fireblocking is mandated whenever a wall exceeds a certain height. The requirement is specifically set at 10 feet.

When a wall reaches or exceeds this height, it creates additional space where fire can travel vertically through the wall cavities. Fireblocking acts as a barrier that helps to slow the passage of fire and smoke, providing occupants more time to escape and assisting firefighters in their response efforts.

Understanding this requirement not only emphasizes the importance of fire safety measures in construction but also highlights the necessity for compliance with local building codes to ensure a safe environment in residential and commercial structures.
