A wall bounds or subdivides spaces. Walls are usually vertical, or near vertical, planar elements, often designed to bear structural loads. It can also simply be an architectural element which is non-load bearing.
A removable partition is a wall that is either movable, such as folding wall or a sliding wall, or can be easily removed as a removable partitioning or mounting wall. Movable walls do normally not define space boundaries and often belong to the furnishing system.
