About Roto Frank

More than 75 years ago Wilhelm Frank invented a product that we can't imagine was unknown up to that point: Tilt&Turn hardware for windows.

Equipped with this steel design, windows could not only be turned and opened for the first time, but could also be brought into the tilted position and the room ventilated via the resulting gap.

A small but practical invention? It's much more than that: It's part of major activity as a developer and the birth of a corporate group with technological expertise that is still held in high regard today.

But what will windows and doors have to do in the house of the future? And what do the occupants and users of a building expect from its openings? The people at Roto repeatedly ask themselves these questions and develop solutions that point the way to the future in response.

Worldwide leading hardware technology for windows and doors as well as major supplier for roof windows and loft ladders.
