We add value to windows and doors.

The SIEGENIA GROUP offers a wide range of products which add value to windows and doors. With its TITAN, ALU and PORTAL product groups, together with the AERO and DRIVE ones, the company is one of the world’s leading suppliers of hardware, ventilation and building technology. In addition to that, KFV provides a complete range of modern locking systems for doors. This comprehensive group of products is completed with the SIEGENIA-AUBI Sicherheits-Service GmbH, which offers products and services for intruder protection and window repairs. Taken together, this results in a high-performance product portfolio for fabricators, designers and architects – from hardware technology for windows and French windows to building technology solutions for building automation and intruder protection to wall and window ventilation, multi-point locks, as well as emergency doors and automatic locks.

1914


On 6 April 194 Wilhelm Jäger (1914-1937) establishes the “Kaan-Marienborn Pressing and Punching Company”

1919


At the end of the war, his son-in-law, Adolf Frank, enters the fledgling company as managing director, which is then known as JÄGER, FRANK and Co. GmbH. It is now that the company begins to successfully manufacture furniture fitting and hardware; and due to his training in the fittings industry both at home and abroad, the young Adolf Frank had valuable experience in this field.

1937


However, the 1920s and 1930s were marked not only by an economic upturn, but also by setbacks, and so it turns out to be the right decision of Adolf Frank - who becomes sole managing shareholder of the Jäger-Frank KG in 1937, by then a limited partnership - to gradually switch production to modern window ventilation hardware.

1937


After the retirement of Wilhelm Jägers, the company becomes the limited partnership JÄGER, FRANK & Co. KG. Adolf Frank is now the only managing partner.

1945


Together with his son, Gerhard Frank, who returned from the war in 1945, Adolf Frank succeeds in rebuilding the company that was badly damaged in the war.

1945


Gerhard Frank (1947-1988) returns from captivity as a prisoner of war and enters the company on 1 July 1945. With the spirit of innovation, openness and persistence, Gerhard Frank moulds the small family business into an international organisation under the experienced eye of his father, Adolf Frank.

1949


In 1949 new screw-on furniture fittings were launched, which no longer had to be set into timber. These included the FAMOS cupboard fitting and the SIEGENIA bed fitting.

1952


The expansion of the company is closely linked to the Federal Republic of Germany’s “economic miracle” and is based primarily on the window ventilation hardware product range, which is sold under the name of SIEGENIA at home and overseas.

1954


The first non-handed turn and tilt fitting captures the market in 1954 and gives the company a distinct competitive edge. ”Turn & tilt“ describes both functions of the window, which allow it both to open and to tilt for ventilation.

1955


And just one year later, the first concealed turn and tilt fitting appears. Fully integrated in the window frame, it renders the mechanism of the turn and tilt window invisible and thus fulfils contemporary architectural requirements.

1955


1955 was the year that the SIEGENIA brand was officially born. The name – which had already been in use since the end of the war – is registered as a trademark with the German Patent Office.

1957


As personally liable partner, Gerhard Frank becomes co-owner of the SIEGENIA company.

1958


With the SIAL, the first night ventilator for windows, which is operated via handle and pull rod, is launched on to the market.

1961


The SOLID, DUAL and VARIANT hardware represent the new generation of concealed turn and tilt hardware from the SIEGENIA company. All three types of hardware are based on a concealed push rod mechanism. The difference between the three types is the location of the operating handle: on the lower sash bar (VARIANT), above the corner gear (SOLID) or laterally centred on the window sash (DUAL).

1962


In the following years the company grows rapidly: 1962 sees the acquisition of a new administration building in Eisenhüttenstraße. JÄGER-FRANK KG now employs over 200 people

1964


1964, the same year as his father dies, Gerhard Frank receives the Diesel gold medal for numerous inventions.

1964


1964 sees 50 years of “Jäger-Frank KG Hardware for the Construction and Furniture Industries“ being celebrated.

1966


Jäger-Frank KG produces the first single operation turn and tilt fitting for aluminium windows with the LM 1000.

1967


The second plant opens in the new Weißtal industrial area of Niederdielfen. The new production facilities here include a modern electroplating system and part of the administration.

1968


The SIEGENIA-COMPACT turn and tilt fitting, which sits on the sash rebate, comprises of just two pre-assembled components form: this simplifies installation considerably and gives the sash greater stability.

1969


The GLOBAL: single operation turn and tilt fitting with “all-round locking”, consisting of pre-assembled components.

1970


In the meantime, SIEGENIA has become such a famous brand that, in 1970, Gerhard Frank renames his company SIEGENIA-FRANK KG.

1970


In the same year, he receives the Order of Merit of the Federal Republic of Germany for services to business.

1972


With the development of the turn and tilt fitting, FAVORIT, of which over 250 million have now been sold, SIEGENIA provides key fabrication benefits for modern window production. For the first time, SIEGENIA launches a fitting that enables the window manufacturer to give windows the “turn and tilt” function in just a few steps, using a manageable number of hardware components that can be easily combined.

1972


On 1 April 1972 the first sales office is opened in Eugendorf near Salzburg (Austria).

1973


In 1973 SIEGENIA presents the “trial gear”, setting new standards in window production: firstly, the retaining pocket for the lock case of the gear is produced in one drilling process and no longer requires the time-consuming process of having to be routed into the rebate. Today, both the component concept and the gear drilling are standard on turn and tilt hardware.

1974


At the start of 1974, the finished-products warehouse, packing and dispatch are relocated to plant II in Wilnsdorf-Niederdielfen.

1978


Thousands of fittings leave the new Plant II in Niederdielfen daily and soon additional production facilities are needed. The production halls in Niederdielfen continue to be extended gradually up to 1984. Fortunately, the two oil crises of 1973 and 1979 interrupt the growth of the company only briefly.

1981


At the start of the 1980s, the product range is expanded to include lift and slide hardware for large sliding windows and doors, and also sound-insulated ventilation.

1982


With around 1300 m² of floor space, the new staff building is opened. In addition to a kitchen and dining room and a training room on the ground floor, washing and changing facilities are located in the basement.

1983


The SIEGENIA AEROPAC is a high-performance and energy-saving wall ventilator, which keeps road, rail and air traffic noise pollution outside, whilst providing a supply of fresh air even with windows closed.

1984


In a further section of the building, a new wing with an area of 4000 m² is put into operation. With a total 29,000 m² of production and warehousing space, the most modern manufacturing facilities provide conditions for ensuring consistent quality. The company employees 700 people and exports more than 20% of its products.

1987


PSK PORTAL is the response to the demand for greater assembly efficiency, for greater operating convenience and for greater security. The first tilt and slide fitting, which can move sash weights of up to 150 kg is launched on the market.

1988


The move from the third to the fourth generation occurs unexpectedly in 1988, as Gerhard Frank dies in the October of this year following a serious illness, aged 68. His son, Wieland Frank, aged 29, takes over the reigns of the family business, becoming managing director and personally liable shareholder.

1989


In the wake of political upheaval in Germany and Eastern Europe following the fall of the Berlin Wall in 1989, the company increases its expansion into other European countries, as well as into markets in the Middle and Far East. Eleven sales and distribution sites are established and the existing ones are expanded.

1989


The family business sets further industry standards in terms of streamlined window production in 1989, with the introduction of the first clamp-on turn and tilt hardware for aluminium profiles.

1994


The double-cup routing for corner and top hinges in timber windows – already prepared in the profile – facilitates painting and the positioning of the pivot point components as well as screw fixing.

1996


With the relocation of the head office from Kaan-Marienborn to the new building in Wilnsdorf-Niederdielfen, the consolidation of administration and production into Niederdielfen – today’s headquarters – is complete. The timelessly modern and exceptional architecture of the new building wins an award from the Association of German Architects in 1997.

1998


With the acquisition of the AUBI Baubeschläge GmbH in Hermeskeil (Rheinland-Pfalz) in 1998, Wieland Frank expands the product and customer portfolio, thereby laying additional and important foundations for the growth of the business in international markets.

1998


And from AUBI a development emerges, which is now an industry standard: the so-called “sash lifter”, which continues to lift the window sash even when sashes start to drop over time as a result of their own weight.

1999


In 1999 SIEGENIA introduce a further innovation in the form of the first parallel window hardware (PAF). The window sash can be partially opened parallel to the frame for night ventilation and the window is also intruder resistant to RC2 in the night ventilation position.

2000


Between 2000 and 2004 SIEGENIA opens plants in China and Poland to serve the rapidly expanding markets in Asia and Eastern Europe.

2002


Simultaneously, the company brings out another innovation into the market, which revolutionises the manufacturing process for window production: the TITAN iP hardware system enables hardware components to be fitted prior to assembly for the first time, offering huge flexibility.

2003


Five years after the acquisition, AUBI Baubeschläge GmbH and SIEGENIA-FRANK KG are merged to form the existing SIEGENIA-AUBI KG.

2004


2004 sees the founding year of the SIEGENIA-AUBI Sicherheits-Service GmbH with its site in Reinsfeld, which specialises in products, solutions and services for retrospective intruder protection on pre-installed windows and for window repairs.

2005


The ventilation technology product group moves to the Lehnscheid site in Wilnsdorf.

2006


2006 SIEGENIA acquires the German market leader for high quality door hardware and locking systems, KFV Karl Fliether GmbH & Co. KG in Velbert. This acquisition completes the product range of SIEGENIA, making the company one of the leading providers of integrated solutions and systems for window and door functionality, and the decentralised ventilation of rooms.

2007


All components that are not cut to length have the new ”Click-Coupling Point“ This coupling point enables linkage and extensions to be installed very quickly. These components are simply pushed in and the coupling point snaps in automatically.

2008


SIEGENIA-AUBI is the first hardware manufacturer in the world to get the ift Q-certification mark.

2008


2008 is the year in which the SIEGENIA-KoPiBo (3D-ComfortMushroomBolt) begins its triumphant march through the TITAN AF hardware range. As the result of its flexible height adjustment, the KoPiBo always compensates for airgap tolerances perfectly and thus reduces adjustment time considerably. Window installers are delighted by it and window users appreciate how easy the smooth-running window is to use.

2013


Today, each of the four German manufacturing sites is responsible for the development and production of one particular product range within the broad SIEGENIA product portfolio; the manufacturing site in Poland has taken on the manual assembly operations which are no longer cost-effective in Germany and the manufacturing site near Peking supplies the Chinese and Asian markets.

2013


New challenges will emerge for SIEGENIA as a result of a world that is becoming increasingly more tightly networked. SIEGENIA products, for example a motorised entrance door lock, a motorised window or sliding door drive, or an energy-efficient, multi-functional ventilation device, can be used in various ways in an “intelligent and networked house” and controlled via a smartphone or the home management system.

2014


Currently, more than 2,800 employees worldwide look after the development, production and sales of products with the SI and KFV trademarks to customers in 80 countries around the world. “The ideas and guiding principles of my great grandfather, grandfather and father have endured, but only innovations and constant constructive change will ensure the continued existence of our company."

2014


The current new construction of an exhibition centre with integrated test centre, together with the building of a state-of-the-art surface treatment plant in Niederdielfen are an indication of the company’s continuous modernisation process.

2014


Investment in both the future and in the location are a clear commitment to the products “Made by SIEGENIA”. The company’s centenary motto, “More drive than ever” underlines the fact that the group will continue to strive to make windows and doors functional and to ensure that fresh air is something everyone should experience.
