Fire walls must be constructed of noncombustible materials, except for those of which type of construction?

Fire walls are designed to prevent the spread of fire between different sections of a building, and they must be constructed of noncombustible materials to serve their purpose effectively. However, certain types of construction are allowed some flexibility with fire wall requirements.

Type V construction is characterized by its wood frame structure, which is the most combustible type of construction. In Type V buildings, the use of fire walls may be adapted somewhat because the entire structure is often framed with combustible materials. In this context, while it is still preferred to use noncombustible materials for fire walls, there may be allowances or alternative approaches to ensure safety without strictly adhering to the noncombustible requirement that applies to other building types.

This is particularly relevant as general fire codes may provide some leeway for fire walls in Type V constructions due to differences in fire load, building height, and occupancy requirements, which may align with the types of materials used in its overall construction. Hence, understanding the context of how Type V structures operate, including their inherent fire risks, justifies why alternatives may exist regarding fire wall material composition.
