Abstract: The invention comprises a thermal breaking system that can be used in the manufacture of windows, doors, and other building components. The thermal break system comprises first and second portions. Interposed between said portions is a thermal break. The thermal break and the portions define a longitudinal channel in which a thermal barrier is integrally formed. The thermal break can comprise a longitudinal flange to increase its adhesion to the thermal barrier. Further the thermal break can comprise four side walls that define a hollow center or void.
