Which term describes a vertical assembly of materials designed to restrict fire spread with protected openings?

The term that accurately describes a vertical assembly of materials designed to restrict fire spread with protected openings is a fire partition. Fire partitions are typically designed to limit the spread of fire within a building and are constructed to survive specific fire resistance ratings. They often feature openings, such as doors or windows, that are protected with fire-resistive assemblies to maintain the overall fire resistance of the partition.

Fire walls, while also important in fire protection, differ from fire partitions in that they are load-bearing structures that not only restrict fire spread but also provide structural separation between different buildings or areas within a building. Fire space and fire panel do not accurately represent established terms used in fire safety standards or codes applicable to building construction and fire prevention.
