Abstract
A composite frame particularly for windows, doors or the like is composed of two metal sub-frames spaced apart from each other. Each of the sub-frame is formed with outwardly extending flanges to define the respective recesses therebetween. A pair of elongated insulating members are inserted into said respective recesses to interconnect the sub-frames to each other. The insulating members are provided with grooves of circular shape to receive the outwardly extending flanges which are deformed to engage the insulating members. At least one elongated gripping element is provided in the assembly which is inserted into a recess formed in each insulating member; the gripping element bears against the respective one of the outwardly extending flanges thereby increasing the coefficient of friction of the insulating member relative to the metal sub-frames. A method of inserting the gripping element which may be made of wire or of elastic cord is disclosed in the application, which gripping element is placed into the respective recess provided in the insulating member.
