The uninsulated folding sliding door ASS 50 FD.NI is the ideal choice in areas where thermal insulation is not required. The door system can be opened fully in passages or used to extend business rooms and offices. The door leaf stack folds easily with minimal force and slides to the right and/or to the left to save space. The individual units are simply folded into a small space and pushed into the corner - quickly, compactly and very quietly. Schüco ASS 50 FD.NI offers the same ease of operation as the thermally insulated Schüco ASS 70 FD series and can be seamlessly combined with other Schüco systems.
