Folding Aluminum Foldline Door
Are you interested?
FoldLine folding doors are a solution for rooms where it is desirable to open the interior to the outside as much as possible. The individual wings fold smoothly to the side, creating a wide passageway that connects the house to the garden or commercial space with an outdoor patio.
The system is based on the MB-86 platform, which is known for its high strength, insulation parameters and long service life. FoldLine enables larger wing formats, variable opening directions and a wide range of glazing types — from standard to acoustic and safety.
With its sleek design, smooth running and minimal maintenance requirements, the FoldLine is suitable for both family homes and modern commercial spaces where flexibility and a visually clean solution are important.
