Abstract: An improved simulated authentic divided-light windows, includes an internal muntin grid structure sandwiched between the panes of a double-glazed sealed window pane, and an external muntin grid removably attached to each side of the sealed window pane. The internal grid is equipped with multiple neodymium magnets, which are embedded in the grid structure at regular intervals, while the back side of each of the outer muntin grid structures is equipped with multiple steel or iron inserts which align with the neodymium magnets when the outer grids are positioned, as intended, on the sash. Outer grids used on the inside of a building can be made of wood or plastic. Outer grids used on the exterior of building are preferably made of extruded aluminum or other weather resistant material. The steel or iron inserts are threadably secured or adhesively bonded to apertures in the back side of the grid.
