Renovation and
construction within existing buildings  

Nowadays, renovations are preferred to new builds, as more and more buildings are being renovated and converted – and for good reason. Renovating existing buildings addresses the urgent issues of climate protection, sustainability and resource conservation. Repair work, modernisation, conversion, expansion and reconstruction are therefore all part of a sustainable trend. In this context, modern hinge technology is essential for using heavy-duty doors retroactively on existing steel frames, as it allows a conscientious, sustainable approach to be taken towards existing construction components down to the smallest details.

Meet current
requirements

Standards, regulations and requirements for fire protection and soundproofing change constantly, so it’s important to always keep an ear to the ground when it comes to hinge technology. Special safety precautions for finger protection, particularly in buildings intended for children, disabled people and people with dementia and public buildings, should also be taken into account. Various models from the VARIANT series help to overcome these special challenges.

Door renovations in existing buildings

The intention behind the open structure of the building constructed from 1965 to 1969 according to the designs of Berlin architect Paul Baumgarten was to convey the idea of democratic transparency. When it came to installing the VARIANT Compact hinge system, the existing frame construction was preserved. With the receiver integrated in the door leaf and the system being fastened to the frame side, this is an optimal solution.
