The NK2-180 Double is a 2-ply fold-up door. Due to its rigid 180 mm wide frame construction, it is particularly suitable as a large exterior door. The width of a single door can be up to 16 m, and the height 20 m. When using an elevating support post system with multiple doors, the door width is unlimited. For very dirty and dusty locations (for example energy wood chip storages) there is a special “dusty room model” available. The door fabric always comes UV-coated, and it is possible to add burglary prevention mechanisms to it, as well. Windows are also available for this door; or the entire fabric can be partially translucent.
