For more than half a century, aluminium has proved its modernity and its reliability as material on the building site. Through its qualities and aesthetics, the light metal material is used everywhere where other materials can offer no satisfactory solution. Küffner has already used this knowledge in the door sector for more than 25 years and set its evolution emphasis with the invention of the double-leaf light metal frame. On account of the timeless elegance and the aesthetic functionality of the aluminium frame, used for subsequent mounting - one could call it the "wood frame made of aluminium", meets with general approval, equally amongst customers, as in the case of architects and designers.
Küffner developed aluminium base profiles as well as a program of wall protective profiles that can be easily mounted an base of a clear shaping language of the aluminium frames for doors and glazings.
Küffner developed further door solutions through the frequent use of corrosion-resistant aluminium frames, base and wall protective profiles in hospitals, nursing homes and schools. The Küffner space-saving door and disabled person door is an essential contribution to the everyday life of mentally and physically disabled people in public, whilst also making it a "design classic".
