The key to success
"In the beginning, I traded in sound insulation for heating systems," recalled DOYMA founder Hans-Ullrich Ihlenfeldt. "Such products were not yet available on the German market: I imported these goods directly from Denmark. With success! By closely observing the construction sector, I recognized an unsolved problem for planners and tradesmen: the sealing of pipe penetrations in buildings! Such seals should be easy to install and provide a permanent, reliable seal against moisture. Consequently, we developed an innovative professional system consisting of a fiber cement lining pipe and sealing insert. A permanently tight and precisely fitting complete solution. We presented this new development at the ISH in Frankfurt in 1967. And it was a direct hit!"
DOYMA GmbH & Co grew out of the consistently pursued basic idea of safe building penetration and continues to write its entrepreneurial success story.
