Ultra-light prefabricated walls (facades), with the ability to be multifaceted, recycle and connect all kinds of internal coverings

These walls have three main layers and several sub-layers, which solve the disadvantages of the current facade of buildings; they are environmentally friendly, light weight, and dynamic in term of design and appearance, and due to their pre-fabricated and sliding construction, construction operations with them are much faster than traditional methods. They are thermally and acoustically insulated and prevent fire from entering the building. These economic walls are resistant to earthquake and reduce labor, and construction pollution.
