Voids created at the intersection of a fire barrier and a nonfire-resistance rated assembly must be filled at which locations?

Voids at the intersection of a fire barrier and a nonfire-resistance rated assembly must be filled at both the roof assembly and the exterior wall assembly to maintain the integrity of the fire barrier. This is essential because fire barriers are designed to resist the passage of fire and smoke, providing necessary protection between different sections of a building. If voids are present at these locations, they can create potential pathways for fire and smoke to spread, thereby undermining the purpose of the fire barrier.

By filling these voids, you ensure that the fire barrier performs its intended function, which is crucial for occupant safety and compliance with fire codes. This adherence to safety protocols helps limit the spread of fire, protecting lives and property within the building while also aiding in the overall fire safety strategy of the structure. The need to fill the voids in both locations reflects a comprehensive approach to fire safety in building design and construction.
