Abstract
A composite structure has a pair of parallel aluminum extrusions bridged by a polymer cap and defining a U-shape hollow. The hollow is filled with an expandable foam that adheres to and mechanically interdigitates with the extrusions, which have channels for receiving insertion legs of the extrusions and have extensions, which the foam encapsulates. End caps may be used to further delimit the hollow. The caps and the foam have a thermal conductivity less than that of the extrusions, providing a thermal break. An upper cap may be used and may incorporate features to compensate for the foam expansion. Excess foam may be trimmed. A forked tool may be used to hold the extrusions during joining.
