ABSTRACT:
This invention relates to heat-insulated structural section assemblies for use in window and door frames. There is disclosed a structural section assembly consisting of an inner and an outer structural metal section, connected to each other by at least one plastic heat-insulating bar held in longitudinally extending opposed grooves of said structural metal sections, and at least one leg integral with one of said structural sections and extending generally parallel to the plane defined by the panel of the window or door frame. Said leg extends from the end of a flange partially defining the groove in said one structural section and said groove-defining flange being forced under pressure onto said heat-insulating bar, said groove-defining flange having a thickened portion which extends the entire length of the assembly on its upper surface facing away from said heat-insulating bar so as to prevent the pressure roller from forming notches in the flange or leg.
