The extruded and expanded polystyrene for building’s insulation has been used mostly in form of blocks. Additionally, polystyrene has a large potential for being sculpted into curved forms at an expense of material waste. In this project, the emphasis is placed on creating no waste material out of polystyrene, while approximating doubly curved surfaces for facade application. The design process allows for quick variations by changing the parameters for insulating layers, width of the ribbons, protrusion from the facade and similar. The entire fabrication process is done by means of an industrial robot and hotwire cutting procedure. More information can be found in the article.
