Company profile of the inventor of the modern louvre windows - HAHN Lamellenfenster GmbH

HAHN Lamellenfenster GmbH – The company profile of the louvre window inventor

The roots of the Frankfurt-based company GLASBAU HAHN go back to the year 1829, founding year of the joinery and glazing company J. R. Schön. In 1870, under the direction of Heinrich Hahn, the Company became known as Glaserei & Glashandel HAHN. 

HAHN has been involved with natural ventilation since the 1950s.

HAHN Louvre Windows since 1953


Back in 1981, GLASBAU HAHN was the first company in the world which developed an insulated Louvre Window

Since then, the "HAHN Louvres" have set a standard in the field of ventilation, and are synonymous with innovation and quality. Louvre windows are customized: with a wide range of single, double or triple glazing or insulated panels, with wooden or aluminium blades or even with special materials such as stone panels. They protect against ball strikes, are burglar-resistant, fall protection safe, sound insulation certified and can be used for smoke extraction as well as for daily ventilation. HAHN louvre windows can either semlessly integrated into a facade or stand out as an attractive part of its design.

Architects and construction companies use HAHN louvre windows to benefit from the experience of an industry expert that has made its name in the field of individual solutions.
