What Siegenia-Gruppe does

Siegenia-Gruppe, operating through its primary legal entity SIEGENIA-AUBI KG (headquartered in Wilnsdorf-Niederdielfen, Germany), is a German manufacturer of builder hardware and building-comfort systems. Founded in 1914, the group employs 1,001–5,000 people across German operational sites in Wilnsdorf-Niederdielfen, Hermeskeil, and Velbert (the latter is the base of subsidiary KFV Karl Fliether GmbH & Co. KG), and maintains localized country presence in 13 markets including Germany, Switzerland, France, Italy, the Netherlands, Poland, Spain, the Czech Republic, the UK, Ukraine, China, India, and Korea.

The company's product portfolio spans five categories: window systems, door systems, sliding door systems, ventilation systems, and smart systems, organized under two primary sub-brands — SIEGENIA (windows, ventilation, smart) and KFV (door locking systems, multi-point locks, panic hardware). Core technology platforms include the TITAN hardware system for timber, PVC, and aluminum windows, the ALU XT and ALU axxent PLUS aluminum hardware lines, the KFV multi-point locking and panic program, the PORTAL family of sliding and lift-and-slide door systems (supporting 150–400 kg weights with motorization options), the AEROMAT/AEROPAC/AEROPLUS WRG ventilation line including heat-recovery units, and connected building products such as the DRIVE motorization series, KNX-Gateway, IO-Modul, smart handles and sensors, and the SIEGENIA Comfort App.

Revenue is generated primarily through one-time hardware sales of components and finished units. The go-to-market is a hybrid B2B/B2C model: direct field sales target window and door manufacturers; specialist wholesale trade (Fachgroßhandel), specialist crafts businesses (Fachbetrieb), and system providers serve as channel partners; a dedicated architect and planner service handles specification-stage engagement; and the company's own e-commerce shop sells replacement parts, ventilation, and smart home products directly to end consumers. Pricing is not publicly disclosed and is handled via quote-based commercial sales for trade customers. The company is privately held under the SIEGENIA-AUBI KG partnership with wholly-owned subsidiaries KFV and SIEGENIA-AUBI Sicherheits-Service GmbH.
