A frame construction for a door opening comprises an elongated aluminum extrusion adapted to be secured to a wall defining the door opening. The aluminum extrusion includes first and second elongated spaced apart members each having an L-shaped profile and having first and second longitudinal free edges which form a channel configuration at least partly open-ended towards the door opening between the first free edges. The sides of the channel configuration are parallel to the plane of the door opening whereas the bottom walls thereof extend towards each other without joining one another. An insulating vinyl strip extends between the first free edges in order to close the open end of the channel configuration. The cavity thus defined is filled with an insulating structural filler material generally made of a rigid polyurethane foam. A thermal barrier is therefore provided in the frame construction as the L-shaped members of the aluminum extrusion are separated by the insulating strip and by the insulating filler material with the latter providing rigidity to the aluminum extrusion. The method for producing this frame construction initially has the bottom walls of the channel configuration integrally joining one another, thereby forming a U-shaped channel which is first closed by the insulating strip and then injected with the structural filler material. An elongated strip is then removed from the bottom wall of the U-shaped channel with the integrity of the frame construction being maintained by the rigidified insulating structural filler material.

A frame construction for a wall opening comprising a rigid metallic member adapted to be secured along a length of a wall defining the wall opening, said metallic member including first and second elongated, spaced apart members each having first and second longitudinal free edges, said spaced apart members forming a channel configuration at least partly open-ended towards the wall opening between said first free edges, an insulating strip means being provided and extending between said first free edges of said spaced apart members for closing the open end of said channel configuration and for defining an elongated cavity therein, an insulating structural filler material being provided in said elongated cavity, whereby a thermal barrier is provided in said frame construction between said first and second spaced apart members which are separated by said insulating strip means and said filler material, said frame construction to receive a leaf hinge thereon while maintaining said thermal barrier, the leaf hinge being positioned for at least partly overlying said insulating strip means while being spaced from at least one of said first and second spaced apart members of said metallic member for maintaining said thermal barrier, the leaf hinge being fastened to said frame construction by way of screws passing through said insulating strip means and threadingly engaging said structural filler material.
