Three-chambered, heavy-duty aluminium sections with a design depth of 86 mm for frames and 77 mm for door leaves
The central chamber of the sections is equipped with thermal breaks with a width of 24 mm for frames and 34 mm for door leaves, which translates into high thermal insulation of the construction.
Specialist fittings designed for the MB-86 FOLD LINE system guarantee comfortable functioning of door leaves with a maximum weight of 100 kg
Large permissible dimensions allow the construction of doors with leaf heights of up to 2,700 mm and widths of up to 1,000 mm
Different versions of threshold solutions: classic (with a swing seal) or convenient (with a low threshold)
A large glazing range of 14 to 61.5 mm allows the use of both one- and two-chambered sealed units, including specialised ones: with improved sound insulation or burglary resistance.
