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 a rear wall having an irregular profile and associated longitudinal edges, with the inner component configured to engage the longitudinal edges of the outer component. The longitudinal edges also include 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.
