Heller Kunststoffe was founded as a sole proprietorship in 1979 by the current managing director Manfred Heller. After starting with simple standard PVC profiles, the company quickly expanded its capabilities.
With an in-house development department, combined with the in-house toolmaking department, the product range expanded, and from then on, the company also processed PVC substitutes, as they wanted to present customers with individually tailored solutions, just like they do now.
A branch was opened in 1994 at the Friedewald location near Bad Hersfeld.
In 1998, the old premises became too cramped and the company moved to Hohe Straße 85 in Herborn-Seelbach to be able to continue to meet customers’ requirements in terms of both quality and availability.
In 2016, the Herborn location was expanded to include an additional production hall and warehouse.
