About aluplast

Milestones in aluplast's company history

A leading innovator in just 30 years

The family-owned company aluplast was founded in Ettlingen (near Karlsruhe in Germany) in December 1982 by Manfred J. Seitz. It has taken aluplast a mere 30 years to transform into a global company, while also protecting its roots as a family-run business.
The company is now managed by Dirk Seitz (CEO) and Patrick Seitz (CMO), the original founder's two sons. In January 2016, Stefen Walter joined the aluplast management team, taking over the areas of production, logistics, quality management and planning operations in his role as COO. Eric Bobay became the final director to join the aluplast team on 1 June 2017: As CBDO, he is in charge of strategic business development.

The existing energeto® system is marketed as a high-end foam-based product and has some of the best stats on the market, even with low construction depths. "energeto® | foam inside" is therefore rated the best window in its class.
