DESCENDING WINDOWS

Kollegger Metallbau is official distribution partner of

HIRT swiss descending windows can be found in private houses and business premises all over the globe. At the push of a button, HIRT swiss descending windows slide downward and open up the room in an unforgettable way. Descending windows are essentially “retractable windows” and are the ideal solution wherever indoor and outdoor spaces blend together – in the living room, for the pool house and the garage, or in event spaces. Descending windows can easily withstand extreme climatic conditions and have proven their worth in the harshest weather conditions.

After 15 years of fruitful collaboration and after having become absolutely confident of the uniqueness of the descending windows system, our CEO Martin Kollegger decided in 2016 to become associate at the foundation of HIRT swiss descending windows. He also joined the governing board. We are looking forward to conjointly realize numerous exciting descending windows projects for exceptional customers in the future.

Kollegger Metallbau did realize many of these sophisticated descending windows projects all over the world.
