ABSTRACT:
An improved thermal barrier extrusion in which a longitudinal metallic channel body has a left side and a right side which are connected together by thermally insulating material. A plurality of projections extending from the channel body sides into the thermally insulating material are provided which have cross-sectional configurations whose width increases away from the base or point of attachment to create bidirectional locking of the thermally insulating material to the channel body sides to reduce longitudinal shrinkage of the insulation material and increase resistance of the thermal barrier to fracture damage.
