The disclosure herein describes a door assembly wherein the front and rear sides each consist of a pair of opposite metallic stiles and of upper and lower metallic cross pieces which, when assembled, define a rectangular opening in the door. A rectangular frame is disposed at the periphery of this opening and is connected to the stiles and cross pieces through a series of moldings. Wood spacers are located at the outer periphery of the stiles and cross pieces while a core of rigid foam fills the interior space defined by the spacers, the stiles, the cross pieces and the moldings to form a bonded door. A second rectangular molding frame is used to secure a window unit inserted in the opening to the bonded structure.
