A spacer bar for use in an insulated glazing unit (IGU) has an elongate strip 230 forming an external wall and two side wall strips (224, 226) mounted perpendicular to the wall. The side walls are spaced apart to form a cavity 222, and are positioned inward of the edges of the external wall to each provide a ledge (232, 234) for accommodating a glazing pane (212, 214). Another strip 220 may be located across the free edges of the side walls to enclose the cavity. The enclosure may contain a desiccant material, and the covering strip may also include perforations 236 that allow the flow of gas to and from the enclosure. The ledges and outer faces of the side wall can be coated with an adhesive or sealant (240, 242) for adhering glass panes. Also disclosed is an IGU including the spacer bar and its method of manufacture. |
