THE COMPANY
Founded in 1992, our products proudly embody the "MADE IN GERMANY" seal. We design and manufacture industry-leading PVC and aluminum windows and doors, insect protection systems, ventilation systems, facade designs, and roller shutters, known for innovation, durability, and ease of maintenance, at our own production facilities.
OUR JOURNEY
Our beginnings trace back over three decades, starting as a small three-man glazing team. Initially specializing in installations and repairs, we encountered challenges with external suppliers. This drove our ambition to produce in-house and led to the founding of ISOGON Window Systems GmbH in 1992. As a valued manufacturer of plastic and aluminum components, ISOGON has established itself today as a 100% family-run business, deeply rooted in community and commitment and driven by our dedicated team.
