This case involves 3 zones between production and offices + services. In the first zone is installed a fixed floor ( approx. 2×5m) to offer an invisible barrier to all operators walking in the room with no problem for the 4 doors used. The remainig 2 corridors needed a different solution as the floor is suspeded for IT and Power cables. Adhesive panels (60×60cm) on top of each tile were installed with no problem of any future needs of inspection or manitenance operations.
