Demountable partition structure

A demountable wall system is disclosed providing metal studs adapted to be positioned along the joints between adjacent wall panels. The studs provide outer flanges which are positioned in kerfs along the edges of the panels and inner flanges which engage the inner surface of the panels. A U-shaped web system connects the inner flanges and is structured with the legs of the U-shaped web spaced from the adjacent flanges except at their extremities so that the legs cushion vibration or sound to minimize their transmission through the stud between the two sides of the wall. The inner flanges have a width exceeding twice the depth of the kerfs so that they engage panels beyond the kerf-weakened edges thereof.
