Fire blocking can be required in walls over what height?

Fire blocking is a crucial fire safety measure designed to prevent the spread of flames and smoke through wall cavities. In many building codes, the requirement for fire blocking typically applies to walls that exceed a certain height, which often aligns with 10 feet.

When walls are built over this height, there is a greater risk for fire to travel within concealed spaces, and fire blocking serves to compartmentalize these areas, slowing down the progression of a fire. This means that for structures with walls taller than 10 feet, fire blocking is mandated to enhance safety and compliance with the building standards.

The other height options do not generally reflect the common code requirements that have been established to address fire hazards in taller structures. Therefore, the 10-foot mark represents a practical threshold for ensuring fire safety within building design and construction.
