Attic with a roof truss based on the external one, brick knee wall.
In new residential buildings, the attic usually has a designed brick wall to raise the roof truss.. This allows the entire floor area to be used for utility purposes.
Due to the strut forces transferred by the roof truss to the wall lath, The knee wall should have concrete bracings with the ceiling bead and an additional beam under the wall panel. The reinforced concrete frame made in this way effectively protects the knee wall against tipping over.
