What is the difference between a fire wall and a fire barrier smoke limiting wall?

A firewall is a structural barrier designed to prevent the spread of fire between different sections of a building, providing a high level of fire resistance and often extending from the foundation to the roof. In contrast, a fire barrier smoke limiting wall primarily aims to limit the passage of smoke and hot gases, while still offering some level of fire resistance, but not to the same extent as a firewall. Fire barriers can be used to compartmentalize spaces for smoke control, whereas firewalls are meant to safeguard against fire propagation.
