Gretsch-Unitas GmbH Baubeschläge

More than just products: Gretsch-Unitas adopts a system-oriented approach. Owing to the range of products, the fabricator can obtain harmonised, compatible components in a one-stop service.

This reduces storage space and increases flexibility: the new series of panic locks 21/23 for timber and steel doors means that eight different versions of a lock can be installed in one and two-leaf escape and fire protection doors.

The OTS 73x series of slide-rail closers with practical modular system: by making the slide rail, axle extension and mounting plate uniform for all application and assembly types, only 11 components are required in order to satisfy all conceivable functional requirements.

The SECURY multi-point locking system technology with extended functions and scope will be presented.

The requirements for windows used as facade elements are becoming more and more exacting. As well as the aesthetic demands on modern facades, planning needs to take account of aspects such as security, ventilation functions, and heavy sash weights.

As specialist in every facade opening method Gretsch-Unitas combines products from its established product range with innovative special components designed for one-off projects with specific customer requirements.

For the diamond-shaped, motor-driven Parallel-Projecting windows in the facade of the Musée d'Ethnographie in Geneva, the Parallel-Projecting friction stays were specially developed and produced as innovative engineering service in a special version. The framed window sashes of the museum with a size of 1250 x 4200 mm and a weight of 110 kg feature a retracting distance of 200 mm.

A frameless window emerged as a result of further development: the patent-protected profile construction with reduced number of components increases the design scope. When closed, the window is fully integrated into the facade. With a mullion width of 60 mm, large formats up to 1500 x 4000 mm with a sash weight of 400 kg can be realized. This window will be shown at the exhibition stand of Gretsch-Unitas Group.
