The FFW7026 is a framed double insulated glazing folding system which operates like an accordion. There are hinges incorporated on the vertical profile, to enable the concurrent movement of all the panels, just by pulling only one of them. The ultra-thin vertical profiles, except for a unique aesthetic look, allow perfect sealing between the panels. This system is suitable for large height openings. There is a threshold as an option for additional protection of mild environmental elements.
