Knee walls are alternatively known as what?

Knee walls are indeed alternatively known as dwarf walls. These are short walls that typically extend from the floor to the ceiling or to a higher point, such as the eaves of a sloped roof. They are often used in attics or under sloped ceilings to support rafters while providing usable space in the area. Dwarf walls can help define a space, support framing elements, and provide stability without extending to full height, which is characteristic of knee walls.

The other options do not accurately describe knee walls. Ceiling beams are structural elements that help support the ceiling, while load-bearing walls are walls that support the weight of the structure above them. Ridge beams refer to structural members that run along the ridge line of a roof, supporting the roof framework. Each of these plays a different role in construction compared to knee or dwarf walls, highlighting the unique function and definition of knee walls.
