ABSTRACT:
A door panel having an insulating foam core and a pair of rigid inner and outer skins preferably formed of steel or other metal. The skins have side flanges with hook portions that mechanically interlock. The interlocking flanges provide a method of mechanically attaching the inner and outer skins of the panel to each other by utilizing the compression and spring back of the core during assembly. A resilient thermal barrier element is interposed between the interlocking flanges to prevent them from making direct contact with each other while at the same time sealing the joint, the thermal barrier element also including a cushioning bead engagable with a similar bead of another door panel to provide a weather seal therebetween. The method of making the panel is also disclosed.
