Blonde Girl Posing At The Wall

Portable walls, such as room dividers or portable partitions, are used to take a large open space and effectively divide it into smaller rooms. Portable walls can be static such as cubicle walls, or they can be wall panels mounted on casters to provide an easy way to reconfigure assembly space. They are often found inside schools, churches, convention centers, hotels and corporate facilities.
Etymology
It is notable that English uses the same word to refer to an external wall, and the internal sides of a room. This is by no means universal, and many languages distinguish between the two. In German, some of this distinction can be seen between Wand and Mauer, in Spanish between pared and muro.
