METAL MIXED BEAM / INSULATING MATERIAL FOR THE PRODUCTION OF THERMALLY BRIDGED METAL JOINERY, PROCESS FOR THE PRODUCTION OF SUCH A BEAM AND JOINERY OBTAINED

摘要

The invention relates to a beam (1) mixed metal / insulating material for the realization of metal joinery thermal break, said beam (1) comprising a core (2) polyhedric, preferably parallelepipedic, thermally insulating material, and two metal profiles (3) solidarisable by snap-fastening to the core (2) in a position in which they extend on either side of the core (2) resting on one of the faces of the core ( 2) and are able to form one, the outer apparent face of said frame, the other, the inner apparent face of said frame. Each section (3) and the core (2) are, in the state secured to one another by snapping, further coupled to each other by an adhesive connection (4).
