Aluminium folding door with thermally-separated frame-lattice design. Design depth of 60 mm. Wall thickness of at least 2 mm.
Frame profiles are bolted together and glued to the leaves of the folding door using mitres. 50 mm finger-pinch protective rubber between the door leaves. Panels made of aluminium or insulating glass. The door leaves are suspended by horizontally-guided roller units and plastic-covered track rollers. The track rollers and door leaves are supported by dust-proof, maintenance-free ball bearings.
Adjustable hinges and guide bolts that are 20 mm thick. Covered bolt lock. Creating an opening for people to pass through occurs with no loss in stability.
