History
ISOVOLTA was founded in 1949 in Werndorf near Graz, Austria, under the name "Österreichische Isolierstoffwerke Kommanditgesellschaft H. Turnauer & Co". The commissioning of the plant built in 1962 in Wiener Neudorf and the associated relocation of the headquarters formed a milestone in ISOVOLTA's history. The consistent expansion of the product portfolio — for example with technical high-pressure laminates for the electrical, leisure and aircraft industries as well as laminates for the furniture industry — and the founding of subsidiaries such as "Thermax Brandschutzbauteile GmbH" formed the pillars for sustainable corporate growth. International expansion began in the mid-1980s with the founding of production and sales locations in India, the USA, China, Spain, Romania, Mexico, Germany and France. The split of ISOVOLTA into ISOVOLTA AG and ISOMAX AG in 2002 allowed a more precise focus and better concentration of business activities and thus supported healthy growth.
