Window technology
The name Gretsch-Unitas is a combination of the name of the company founder Viktor Gretsch and his UNITAS metalware factory where the successful Unitas Horizontal-Pivot window hardware was manufactured. The patent for sliding door hardware was registered as early as 1924 and in 1958, with the invention of the Lift&Slide system and subsequent further development in 2017 to a fully barrier-free Lift&Slide door, the HS ePOWER, Gretsch-Unitas group set standards that have had a profound effect on the market up to the present day.
Effortless tilting, turning, lifting and sliding

Hardware is produced for all kinds of window shapes, profiles, materials and opening types – such as Parallel-Slide, Parallel-Slide lightweight, Tilt&Slide, Lift&Slide, Fold&Slide and Tilt&Turn. Owing to its special systems expertise, Gretsch-Unitas can be your reliable partner – whether you need standard hardware with high quality workmanship or a special solution adapted to individual requirements.
Gretsch-Unitas provides new solutions which provide convincing answers to current challenges in the industry and therefore sets the trends for the future in the international market. At the same time tried-and-tested products are also continually developed thus securing their active future. After all, GU group nurtures a distinctive culture of innovation. More than 1,400 patents GU has registered up till now for its designs are testament to this. They set standards in the industry – now and in the future.
In-house development is a particular strength of the brands. After all, the GU experts always adopt a system-based approach when working on new solutions and products. While they have a full overview of the individual product and its strengths, they also look beyond the product and consider the networking options and potential compatibility with the Gretsch-Unitas solutions world. This approach to development is possible because the engineers always keep the overriding objectives of applying the technology – such as security and comfort, barrier freedom and efficiency – in their sights.
The right hardware for every window solution
This is because windows have developed into internationally traded goods to an increasing extent over recent years. As a result, fabricators in this global market have got to offer many different variants. This is where Gretsch-Unitas sets the standards as a tried-and-tested partner to the window industry. After all, GU has the right hardware solution for every window.

Standard hardware intelligently supplemented – special solutions
Modern, creative architecture places very high demands on the design and function of facades. Their form and function can be implemented thanks to the unusual expertise from Gretsch-Unitas. This is because experts take project-related special parts developed exclusively for individual projects as innovative engineering work and combine them with elements from the tried-and-tested GU assortment. In this way, the requirements for novel opening types and shapes of windows can be met whilst retaining unique aesthetic appeal, while the costs for the fabricator remain totally competitive.
