History

Tradition Ahead of its Time

We don’t leave anything to chance on the way to the future. That’s because the window and door market expects innovative solutions for the challenges that an increasing internationalisation, market concentration and differentiation brings. We are therefore focusing on high product quality and innovation, giving the market new impetus.

We use the great potential of two traditional firms: the family business SIEGENIA-FRANK KG and the former Krupp-Hoesch subsidiary AUBI hardware GmbH thus enabling us to keep one decisive step ahead.
