An innovative use of Covestro's Makrolon polycarbonate sheet can be seen in the Breathing Skins showroom in Germany, which demonstrates a permeable outer envelope for buildings that adapts the indoor climate to the needs of the occupants.
Mimicking the natural permeability of skin, the facade has pore-like air ducts which can open and close and allow ventilation without creating a draft. The facade is more than 10 metres long, has an area of 25 square metres and is split into several elements. The load-bearing parts of the sandwich facade elements are all made of solid and transparent polycarbonate sheets.
Tobias Becker invented and obtained legal protection for the Breathing Skins facade technology while he was studying architecture at the University of Stuttgart. He has been presented with Germany's Federal Ecodesign Award in the Young Talent category in recognition of his project.
Covestro recently won the innovation award of the European Polycarbonate Sheet Extruders Organisation (EPSE) for this development.
