Abstract
A sealed glazing unit simulating the appearance of a traditional divided-lite window has spaced apart parallel co-extensive glazing sheets interconnected by a peripheral seal. Muntin grid elements are located on at least two surfaces of the glazing sheets in mutually aligned registration, the elements being of a width sufficient to create a visual illusion of solid muntin bars within the glazing sheet cavity. Each of the muntin grid elements has on one side a relatively dark shade facing interiorly of the glazing unit and in the opposite side a relatively light shade facing exteriorly of the glazing unit, the combination of these shades creating the visual appearance of solid muntin bars within the cavity. Muntin grid elements within the glazing unit are preferably in the form of strips of plastic material adhered to the cavity glass surfaces, whereas muntin grid elements on the exterior surfaces of the unit can alternatively be formed as relatively thick members e.g. of wood, or of hollow aluminum or plastic.
