Innovative Aluminum Folding Sliding Doors
MB-86 FOLD LINE HD folding sliding doors represent the pinnacle of innovative folding systems, engineered with attention to detail and the highest quality standards. The doors meet stringent technical requirements and enable the creation of impressive opening sizes — up to 3 meters in height and up to 1.2 m in width. Three-chamber aluminum profiles with a construction depth of 86 mm for the frame and 77 mm for the sashes, combined with advanced thermal break technology (24 mm for frame and 34 mm for sashes) deliver exceptional thermal insulation performance. Doors can open outward or inward, with sashes configurable to your needs — configurations are available with up to eight sashes, including corner and panoramic variants. The system is compatible with the MB-86N window and door system, offers an extensive range of threshold solutions, and supports both double and triple glazing from 13.5 to 61.5 mm, including acoustic insulation and anti-burglary solutions.
