Which of the following is NOT a type of framing used in residential construction?

Truss framing is often referred to in the context of roof systems or floor systems rather than as a framing system for the overall structure of a building. Unlike platform, balloon, and post-and-beam framing, which focus on the structural framework that defines the walls and is common in residential building, trusses are typically prefabricated components that are used to create the roof or floor structures.

In residential construction, platform framing involves building the structure one floor at a time on top of the last, balloon framing involves long, continuous wall studs that extend from the foundation to the roofline without horizontal breaks, and post-and-beam framing uses vertical posts and horizontal beams to create a more open interior space. These framing types provide the main structure and support for the walls, floors, and roofs of buildings, while trusses serve a specific function within that framework. Therefore, identifying truss framing as not a type of residential framing reflects its unique role compared to the other methods listed.
