Complete range for windows and doors The SIEGENIA GROUP produces and supplies a comprehensive portfolio of products and systems that provide room comfort. While SIEGENIA is one of the world's leading companies for fittings, ventilation and building technology, KFV covers the entire field of modern locking systems for doors. The complete range for windows and doors is rounded off by SIEGENIA-AUBI Sicherheits-Service GmbH, which positions itself on the market with products, solutions and services for burglary protection and window repairs. Product development at the highest level The group of companies consistently focuses on "solutions inside" - holistic solutions for the modern living and life of tomorrow that correspond to the trends of the time and combine economical processing with contemporary design and high end user benefits. In addition to the development of high-quality products, this also includes openness to country-specific and customer-specific solutions. Fourth generation family business The fourth generation owner-managed company was founded in 1914 by Wilhelm Jäger, who manufactured small iron and stamped parts for the Siegerland-based equipment manufacturing industry. From 1919, son-in-law Adolf Frank expanded the portfolio to include fittings for the German furniture and window industry - a development that was consistently continued by his successors Gerhard Frank (1947-1988) and Wieland Frank (1988 to today). After Wieland Frank acquired AUBI Baubeschläge GmbH in 1998, the company was merged and renamed SIEGENIA-AUBI in 2003, followed three years later by the takeover of KFV. Today, the group of companies has numerous production and sales locations in Germany and abroad. Full imprint at: http://www.siegenia.com/de/imprint.html
