HISTORY

Our Story began about 20 years ago with the founding of a glazier. A three-man operation with a lot of creative energy. In the first years our activity was limited to the repair and installation of windows, doors and glass elements. Within a few years 15 employees were employed in the company. The windows were supplied by outside companies and we often had to contend with problems of quality and punctuality of our suppliers. This led to angry customers and we decided to manufacture the windows and doors on our own. To realize our goal of offering the customer a product from a single source, ISOGON Window Systems GmbH was founded in 1992. ISOGON has since become an established and experienced professional manufacturer of components made from plastics and aluminum.

Today the ISOGON Window Systems GmbH is a 100% family-owned company, supportive and with social responsibility towards its area. It's motivated employees are a guarantee for the long-term success of the company.

ISOGON - windows that perfect your home.
