Traditionally, they feature a vertical sliding mechanism within a boxed frame. Today’s sash box windows retain the period charm while meeting modern performance standards. They are available in timber for an authentic, heritage appearance; and aluminium and uPVC for low-maintenance, durable, contemporary alternatives.
