On 17 August 1973, Gerhard Rosenberg founded aquatherm GmbH - in the basement and garage of his private home. His ambitious goal? To revolutionise the market. This vision gave rise to the world market leader for plastic pipework systems made of polypropylene for plant construction and building services: aquatherm. Why polypropylene? Because of its outstanding ecological properties and high temperature and pressure resistance. Today, we are represented in around 70 countries around the world with our long-standing partners.
