Abstract: A method to cast-in-place thermal barriers to create a hollow tubular extrusion is disclosed herein. Clips, configured to engage and lock with a first and a second extrusion profile, maintain a pocket with precise tolerances into which liquid polyurethane is poured. The clips easily engage in a manner to form a hollow tubular extrusion assembly. Once the assembly is made, it becomes very difficult to take the assembly apart. This feature allows the first and the second extrusion profiles to be cut to length or handled without the potential of the assembly coming apart prior to pouring the liquid polyurethane. Once the polyurethane cures, there is no need to remove the clips because the clips are made from a very low conductance material, and the clips can remain as part of the finished product thus saving the expense of removing and discarding the part.
