Which joint type connects a floor and wall?

The joint type that connects a floor and a wall is referred to as the Floor-to-Wall joint. This joint is critical in construction as it helps provide necessary structural support and an effective barrier against fire and smoke from one compartment of a building to another.

The Floor-to-Wall joint facilitates the transition between these two major structural elements, ensuring that the integrity of firestop systems is maintained across this boundary. Proper detailing and installation of this joint contribute to the overall fire-resistance rating of the building and help prevent the spread of fire and smoke throughout the structure.

While other joint types such as Head-of-Wall are important in different contexts, they specifically address the connection at the top of walls to ceilings or roof structures. Similarly, Curtain Wall and Wall-to-Wall joints serve specific design and functional purposes but do not pertain directly to the connection between floors and walls in the same foundational sense as the Floor-to-Wall joint.
