Our family-owned enterprise domiciled in Herdecke, Germany, looks back on more than 120 years of experience with innovative products. This long-standing tradition of know-how and continuous growth has made Dörken GmbH & Co. KG what it is today. As an independent subsidiary of Ewald Dörken AG managed by the third Dörken generation, we think in terms of decades, not business years. Thus, we are able to make long-range plans and act sustainably even in dynamic markets.

KG one of the leaders in the European market for building materials. For more than 50 years, high-quality laminated sheets for roofs, façades, and cellars have been made in Herdecke under the brand name DELTA®.
Where roofs and cellars are concerned, our most important tasks include taking steps to ensure greater safety and better protection from moisture, as well as contributing materially towards saving energy. This is why we develop products tailored to specific functions in collaboration with building-material manufacturers, planners, and craftsmen. The result: holistic, sustainable solutions 'from cellar to roof' that stand out mainly because of three merits: they are safe in application, user-friendly, and durable
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 conforming to DIN EN ISO 9001:2000, DIN EN ISO 14001, and EMAS II – the so-called eco audit. By doing so, we voluntarily undertake to further develop our corporate environmental protection system beyond legal requirements and in conformance with specific environmental objectives, and to prove this conformance by complying with strict criteria.
