The Development of OKALUX

The Beginnings

1963: The textile company Heinrich Otto KG is on the look out for a new business area outside of its own branch. A department in the subsidiary Fils-Textil experiments with hollow fibers of polyester granulate (capillaries).

1964: The first product is created: OKALUX.  Hollow fibers are compressed to slabs and inserted in the cavity of insulating glass panes. The light diffusing and heat insulating properties are very convincing.

1965: The first capillary products are presented to the public at the Environmental Fair in Dusseldorf. The response exceeds all expectations.

OKALUX is founded as an independent company. The name is derived from the first letters of the department name and the Latin word for light – Otto Kapillar Lux. Production is in a garage in Kreuzwertheim. OKALUX has only five employees.

1971: OKALUX builds its own production hall in Marktheidenfeld. The company now has about 30 employees and its first commercial agents.

Early 1970s: OKALUX supplies building projects for Europe’s largest packaging manufacturer Schmalbach-Lubeca as well as for the Olympic Games in Munich – two important contracts that pave the way to the company’s success.

Establishment on the Market

1974: First foreign representatives are set up in Austria and Switzerland.

1976: OKALUX makes its product debut at the world’s leading trade fair BAU in Munich.

Starting 1976: OKALUX‘ continuous growth is also reflected in the steady expansion of its headquarters. New production or warehouse facilities are built almost every five years. A milestone is the construction of a modern administration building in 1994.

1976 – 1980: The sphere of activity grows – foreign representatives in France and Great Britain join in.

1980: OKALUX now employs 60 people.

Beginning of the 1980s: International contracts become part of the project portfolio early: starting 1980 renovation of Westminster Palace in London, 1984 extension of the Museum of Modern Art in New York.

Mid-1980s: Energetically optimized building shells come into public focus. The product of the moment is OKASOLAR – an insulating glass with an integrated light directing system.

Starting 1988: OKALUX launches a widely praised product Innovation: Transparent Heat Insulation façades, as shown in the Youth Education Center Windberg in the Bavarian Forest.

End of the 1980s: An important milestone: Mercedes in Rastatt with the largest contract volume in the history of the company to date – 30,000 square meters of OKALUX.

1991: In the meantime, OKALUX is involved in building projects around the globe. The leap to Asia is achieved with the Temasek Polytechnic School in Singapur by James Stirling, Michael Wilford and Associates.

1995: OKALUX establishes foreign representation in the USA.

Laying the groundwork for the future

International business is reinforced by a number of new representatives outside of the German-speaking area.

2000: A highlight: The complex overhead construction of the Great Court in the British Museum London by Foster + Partners.

2002: OKAWOOD timber grids were created in collaboration with the architectural office of Mahler Günster Fuchs. This is a glass element with filigree timber grid insert.

2004: OKATECH expanded metal is created in collaboration with the architect Rem Koolhaas. The glazing with expanded metal emphasizes the technical appearance of the Seattle Central Library.

2005: With its OKACOLOR, OKALUX is the first company ever to use digital print on glass.

2008: OKAGEL complements the product portfolio. An extreme example of application for the insulating glass filled with aerogel is the British Research Station Halley VI in Antarctica.
