History
Vitrocsa was invented in Switzerland in 1992 by watchmaking engineer Eric Joray, who redefined architecture by making window frames invisible. In 1989, Eric Joray created Orchidées Constructions SA to develop and construct greenhouses and conservatories, building more than 800 traditional conservatories in a few years. In 1992, he invented the Vitrocsa minimalist window, entirely manufactured in the Swiss town of Saint-Aubin-Sauges in a former watchmaking building. In 1993, the Vitrocsa 1001 and 2001 windows were launched, and the first Vitrocsa window was installed in a villa close to Geneva, created by Swiss architect Andrea Bassi. In 1994, Eric Joray registered the Vitrocsa trademark and the first patent for the Vitrocsa sliding system. In 1995, several traditional conservatories were created using Vitrocsa 2001 windows. In 1996, with the collaboration of Swiss architect Andrea Bassi, Vitrocsa came up with a new design for the Vitrocsa 3001 window. In 2000, multiple extensions of homes and new-builds were constructed using Vitrocsa 3001 windows. In 2002, Vitrocsa developed the guillotine solution and launched in the European market. The company states it now exports its systems to more than 60 countries across five continents, and its micromechanical components and systems are designed in Yverdon-les-Bains, Switzerland.
