Abstract
An entry door system constructed of panels having a metal skin filled with insulating rigid foam core and having a unique wood facing and whereby the system has exceptional insulating qualities while projecting the beauty of a wood door. The system includes door and side panel components of substantially the same construction, except for the size, and provides for a versatile arrangement of panel components which in different selected combinations can be secured together into a single unit ready to be installed. The wood facing of the core filled panels includes wood stile and rail facing pieces and one or more raised panel subassemblies comprising a base panel to which is secured a raised panel with decorative wooden beads located at their perimeters which creates a wood picture frame look on the outer surfaces of the panels.
