Wall is a steady, firm, monolithic, and extensive structure of different kind of materials, which its thickness being thin compared to the length and height; walls act usually as isolators of spaces from each other in the form of parts or rooms or being the preservers of a space. These vertical structures, in addition, are the carriers of building weight to the earth. In this study, most known wall types will be debated besides a wide technical focus on 3dimentional (3D panel's walls). Three dimensional walls consisted of two reinforced concrete layers and an insulator core with varying thicknesses to supply required attributes.
