The present invention relates to frames for use on windows and glass doors and methods of making same, and particularly, methods of making a thermally broken window or door frame made from two frame members that are connected by an insulating member. Existing methods of making thermally broken hollow frame members from two frame members either are complex and time consuming and complex or present difficulties in aligning the two frame members prior to pouring the thermal barrier material. The present invention provides the use of a guide to hold the frame members and am elastomersic gasket which forces the frame members tightly inot the guide and seals the liquid-receiving channel. The frame members can then be inverted in the guide and the process repeated to produce a hollow thermally broken frame.

La présente invention vise des cadres de fenêtres ou de portes en verre ainsi que les méthodes de fabrication connexes, et en particulier, les méthodes de fabrication de cadres à pont thermique rompu et constitués de deux éléments d'ossature raccordés par un élément isolant. Les méthodes connues de fabrication de tels types de cadres sont complexes et fastidieuses ou encore présentent des difficultés lorsqu'il s'agit d'aligner les deux éléments d'ossature avant la coulée du matériau destiné à assurer la barrière thermique. La présente invention fait appel à un guide servant à maintenir les deux éléments d'ossature et à une garniture en élastomère qui permet d'emmancher serré les éléments dans le guide et assure le scellement de la cannelure servant à recevoir le matériau isolant. L'ensemble peut ensuite être retourné et le procédé peut être répété aux fins de production d'un cadre à pont thermique rompu.
