Which type of fireproofing does not protect individual structural members?

Membrane fireproofing is designed to protect entire assemblies rather than individual structural members. It is typically applied as a coating to walls, ceilings, and floors, creating a barrier that is meant to protect the contents of a room as well as reduce fire spread. This type of fireproofing works by forming a layer that insulates and protects an entire surface area, rather than applying a thick coat to each member, such as beams and columns.

On the other hand, sprayed fire-resistant materials, cementitious fireproofing, and intumescent fireproofing are specifically designed to cover individual structural elements. These materials adhere to steel or concrete members and provide thermal resistance directly to those components, helping to maintain structural integrity in the event of a fire. By contrast, membrane fireproofing serves a different purpose, focusing on overall compartmentation in a building rather than the protection of specific structural elements.
