The Modular System, movable glass partitions of Grupsa, come characterized by their functionality and easy use to optimize the division between areas. There are a wide variety of forms and customized designs that give the necessary flexibility to subdivide areas for specific purposes even in certain hours thanks to a simple manual performance of opening and closing. The plant drawing of a Movable Glass Partition can be straight, circular, polygonal, angular and ellipsoidal leaving a clear area when they are piled up within the prking. The MS-150 allows, at the same time, for the authorised passage of people when they are closed, through an integrated pivoting door.
