摘要
The subject application is directed to a composite spacer bar for use in glazing units. The spacer bar includes a low-thermally conductive inner component and a low-thermally conductive outer component that partially encases the inner component. The inner component has four walls of a predetermined thickness that define a chamber containing a low-thermally conductive material. The thickness of the outer component is substantially less than the thickness of the inner component. The outer component also includes associated longitudinal edges, with the inner component configured to engage the longitudinal edges of the outer component. The outer component also includes a portion that extends a predetermined distance into the top wall of the inner component. The composite spacer bar is also configured to receive a linear key member that is configured for insertion into the chamber so as to join ends of the spacer bar.
