Simple, slim frames and a flush exterior look make Josko’s innovative FixFrame lift-and-slide doors a captivating choice. This innovation won the Red Dot Product Design Award 2009. The award is recognised internationally as a seal of quality for design. The sliding wing is available on the outside as a high-end, optional solution with flush-fitting layered glass or with an almost flush-fitting aluminium frame. The continuous transition to the ground on the outside is barrier-free. The ground outside meets the slim rail of the wing. This lift-and-slide door is also available as "Platin HS", a compact installation part with no elements to be joined.
