An aluminium-glass curtain wall inter-storey band  produced as a mullion and transom construction. It is a curtain wall element located in the ceiling area. It is the section of the curtain wall within its connection with the interstorey ceiling, extending from the top edge of the aluminium transom above the ceiling of one storey to the bottom edge of the transom on the storey below the ceiling.
