Abstract

Rolled T-beams of the kind used in suspended ceilings, act as vertical stiffeners in a wall liner for a back wall. The vertical stiffeners, reinforced from the back wall, keep the sheets of wallboard that form the wall liner vertically aligned and together. The weight of the wallboard liner is borne directly by the floor under the liner, without support by columns or studs.
