Portavant 80 automatic by VITRIS is an innovative, automatically operated, all-glass sliding door system for use in luxuriously appointed residential and office environments. Compared to manually operated all-glass sliding doors, Portavant 80 automatic has the advantage of offering no barriers to access and of being much easier to go through as no pushing or pulling is needed. The purist design of the sliding rail enables it to be discreetly incorporated into the system, so that it fits unobtrusively into any environment and optically harmonises with every style of interior design.
