    We go ahead sustainably

    Sustainability has been a hallmark of the DNA of a family company like Dörken from the start. No wonder, then, that life in such an environment is uniquely characterised by friendly coexistence between the young and the old generation. Within such a corporate culture it almost goes without saying that ecological progress is being made systematically as well; after all, the welfare of our grandchildren and their grandchildren is always at stake, too.  

    Quality management systems are a good thing, but a management system that combines quality, safety, economy, and environmental protection is much more forward-looking. For this reason, Dörken GmbH & Co. KG has established a combined quality, workplace safety, and environmental management system under DIN EN ISO 9001:2000, DIN EN ISO 14001, and EMAS II, a.k.a. eco-audit. Thereby, we voluntarily undertake to continue developing our corporate environmental protection in conformance with defined environmental objectives even beyond legal requirements and to document this by adhering to strict criteria.

    Our laminated sheets division was certified under EN ISO 9001 as early as 1994. Both in Germany and abroad, the quality of our products is regularly certified by independent institutes and experts. In matters of quality, we often go one step further: many products conform to a new standard long before such conformance is required in law. Our slogan 'DELTA protects property. Saves energy. Creates comfort.' is the leit-motif as well as the programme of Dörken GmbH & Co. KG: out of respect for nature, the aspect of environmental protection is strictly observed everywhere.

    But we proceed sustainably not only with regard to our products. Our employee training system is forward-looking too, and the training rate is high.

    Our engagement knows no bounds!

    In the Westphalian town of Herdecke, Dörken has expanded to the boundaries of the land that has been available for generations. To facilitate further expansion, we have been developing a site at Hagen-Vorhalle since 1999. Most recently, a state-of-the-art spunbond production facility was opened there in 2015.

    From our headquarters at Herdecke, a worldwide network of subsidiaries stretches to Belgium, France, Italy, Canada, Poland, Russia, Switzerland, Slovakia, Czechia, Turkey, and Hungary, including numerous sales partners. For manufacturing dimpled sheets, we have additional production sites in Canada and Turkey.

    There are many other countries where Dörken has been co-operating for many years with sales partners who not only have accepted Dörken's sales concept but live it. In this way, we not only export goods but influence standards and manufacturing guidelines, sales paths, and marketing and, not least, the personalised consultation of customers on the spot.
