The modular wall comprises a steel structure containing galvanised, cold-formed steel studs with different cross-sectional shapes: ‘C’ (100 x 40 x 10 X 1), ‘U’ (75 X 40 x 10 X 1) and ‘Z’ (75 X 25 X 1). Each wall module is 1.2 m wide and 2.49 m high. Figure 1 shows the steel structure containing insulation between the steel pro- files as well as in the external layer.
