In 1967, master designer Manfred Diedrichsen, together with Alfred Sharkowski, founded in Germany a small business of improving simple curtain rods which people we using those days. And in span of a month they have already patented the design of their first invention. And up to now this German company produces modern wall and ceiling curtain rods in a very high-tech style. Interstil window systems are being constantly improved and getting more sophisticated and reliable every year. The implementation of various innovations has brought many international awards to the company. Many of those were given to the well knowd designer Frank Greiser, who has been working with Interstil for more than 10 years. |
