Abstract
The present invention relates to a door assembly which has a lower door assembly and an upper door assembly, and the upper door assembly and a lower door assembly can be connected. In addition, the upper door assembly is at least partially made of composite materials. Thus, the upper door assembly can be completely constructed with composite materials or it can be constructed of a hybrid material which consists of composite materials and steel. Furthermore, the door assembly can have trim molding integrated into the upper door assembly during the molding process. In the alternative, the door assembly could have an upper door assembly where attachment areas are molded into the upper door assembly which will allow for trim molding to be easily attached to the upper door assembly.
