Abstract

The transparent envelope theme was born and developed with the invention of the “rotule” (kneecaps), or the articulated bolt fastening that has eliminated the perimeter frame support, essential raw. Have been so made the large glass surfaces, "sails Crystal" all-glass, with a few supporting components and thin cables for bracing. But has also continued to use other systems, such as punctual studs or VEC (glass glued with structural silicone), as in the Lingotto in Turin by Renzo Piano Bubble, or has returned to the classic frame, even on complex geometries, like sailing for the Fiera di Milano Massimiliano Fuksas. The performance targets, in the field of transparent wrappers, are now facing not so much in search of extreme lightness and reduced support components, but rather, the level of comfort of use, in terms of light control (solar screens, solar shading, tents) and energy flows (dual-chamber glass, low-emissivity treatments, double skin facades). One of the novelties in the field of transparent packaging is now made by ETFE (Ethylene Tetrafluoroethylene), a transparent film that is used in layers to form the "pillows" inflated with air. The internal pressure gives mechanical stability to the cushions and the capacity to carry the loads of snow and wind, while the presence of the air chambers makes the cushions of the excellent insulating elements from the thermal point of view. One can easily understand what benefits can be obtained and made, with a weight of 3 kg / sqm, a casing having the same insulating power of a 60 kg / sqm glass room. Ideal for large covers, where the supporting structure can become the ETFE was used for the Water Cube of the recent Olympic Games in Beijing (PTW Architects), but already in 2000 had made possible the construction of the biospheres of Eden, very lightweight and flexible Project in Cornwall (Nicholas Grimshaw), the first closed casing in which the contained weight of the air is greater than the weight of the casing itself. A recent example of use is the new multimodal station in Northeast Paris, the RER E, designed by AREP Group and entry into service in December 2015.
