A door assembly and a frame member for a door assembly. The door assembly may include at least one door panel and a door frame having a plurality of frame members including a header and a pair of side jambs. The invention may also be considered a frame member including a storage compartment. The frame member may include a core; and a top piece adjoining the core to form a structural member. The core and the top piece may be a composite of cellulosic material and at least one other material. The top piece may be a two-piece top piece and may include hollow cavities. Also disclosed are door jamb frame members and mullion frame members.

The present invention provides a door frame comprising of two piece units and the method of installment to provide connection between the casing and the frame with a self-alignment system. This is done by a tongue and groove connection and plurality of prefabricated dowels that are specially formed to engage the grooves provided in the frame through the entire attachment area of the frame units together. The door frame units are being assembled and secured together by providing a solid reinforced assembly. In the door frame system of the present invention a strong square joint can be produced by inserting dowels at critical joints which is significantly stronger fastening mechanism than other fastening means such as nails, staples, etc. Low expansion reinforced foam fills the cavities of the frame and creates a solid bond between door system and casing.

A trim structure intended on one hand to receive a door, in particular an internal door, and on the other hand to be joined to a partition. The structure includes two lateral wails facing one another and spaced apart by a thickness. The thickness being adjusted with respect to the thickness of the partition such the lateral walls form an external surface that is flush with the external surface of the partition. when the structure is joined to the partition. A transverse end wall connects the two lateral walls. The transverse end wall includes a planar surface that is configured to butt up against the thickness of a vertical edge face of the door and a projecting element (15) forming a bearing surface for the door. The walls being formed from at least one composite panel, the panel comprising a central layer sandwiched between two facing layers.
