ABSTRACT:
Disclosed is the utilization of two halves for a door with tops, bottoms, and sides defining circumambient outside portions and a window portion having tops, bottoms, and sides forming a window circumambient portion, in which the circumambient portion of the outside and the circumambient portion of the window opening constitute dams which will preclude the flow of a foaming material. When the two door halves are secured together, the interior voids are filled with an expanding foam such as a two part urethane. The foam can be inserted through ports in the bottom and/or the top. In the final form, the frame two halves are secured together adhesively by the foam which adheres to the entire inner skin of both halves. The foam also provides insulation. Additionally, the foam reinforced by the skins imparts substantial structural strength to the door.
