Abstract: A compound portal frame extrusion profile of that type employed in the manufacture of insulated portal frames for windows or sliding doors and the like, wherein the compound portal frame profile is fabricated by means of a cooperative mechanical clamp assembly structure provided integral to a set of separate lineal portal frame profile extrusion components and a fabrication method is employed based on the utilization thereof which enables the interim lineally aligned interlock connection of the separate portal frame profile extrusion components, in turn being of either two dissimilar colors or materials or a combination thereof respectively for the interiorly and exteriorly outward facing finished compound portal frame extrusion profile component members, to thus form an intercommunicating resin receiving trough for containing and supporting the progressive injection deposit therewithin of a thermally non-conductive resin-bonding material by which is formed a structural interlock connection joinably between t
