This spacer for paneled hollow-core doors has an H-beam configuration, with a first flange connected along its length to a second flange along its length by a web. The web is perpendicular to both the first and second flanges. A hollow-core door is assembled by placing the spacer between two door skins. Once the door is assembled, the web is parallel to the door skins. To accommodate the variation in distance between the bottom and top skins that is created by the raised panels, the bottom edge of each flange has one or more bottom notches that fits closely over the raised portion of the panel in the bottom skin and one or more top notches that fits closely over the raised portion of the panel in the top skin. Preferably only two or three spacers are used in a paneled door, each spacer extending the length of the door.

A door frame component is provided. The door frame includes: a front wall, a rear wall, an outer wall and an inner wall; a length of the front wall being substantially the same as a distance between the inner wall and the outer wall; an internal cavity at least partially defined by space between the inner wall and outer wall; and opposing first and second gripping sections defined in the internal cavity at least partially by first and second internal flanges in the internal cavity. The frame has sufficient structural integrity such that when the frame is cut height wise between the first and second internal flanges into front and rear sections, the front section can support a door on its own without the rear section.

A door panel comprising a body having front and rear door skins sandwiching, at least partially, two stiles, which together delimit an interior for injection of filling material. At least one of the stiles comprises a hollow structure with a partitioned hollow interior that extends along substantially the entire length of the body to offer mechanical strength to the door and to provide foundation for installing door fittings.

A metal door frame for a door opening comprising at least one first door frame segment for upper or side portions of the door opening, the at least one first door frame segment having a first molding flange, a first jamb face adjacent to the molding flange, and a first stop flange adjacent to the jamb face. The metal door frame includes at least one second door frame segment for upper and side portions of the door opening, the at least one second door frame segment having a second molding flange, a second jamb face adjacent to the molding flange, a second stop flange adjacent to the jamb face, a second stop face adjacent to the stop flange, and a third stop flange adjacent to the stop face. The metal door frame includes a thermally insulative layer between the first door frame segment and the second door frame segment.

Systems and methods for pressing a door assembly involve one or more die sections installed in a press, wherein the die sections each have a raised section that contacts and supports a recessed panel portion of a door skin of the assembly during the pressing operation to facilitate crushing of portions of a core of the door assembly that underlie the recessed panel portion of the door skin. The die sections may be made of plastic and readily changed out for different sizes or styles of doors.

A door includes a door frame, first and second door skins having rectangular outer peripheries and inner openings, and a frameless glazed unit received at the openings. The door skins include exterior surfaces facing away from the door frame and opposite interior surfaces facing and secured to opposite sides of the door frame. The exterior and interior surfaces of the first and second door skins establish integral lips and grooves of the first and second door skins. Opposite sides of the frameless glazed unit directly contact and are sealed by the integral lips and sealant and/or adhesive contained in the grooves of the first and second door skins.

A welded steel door including a pan having a bottom surface forming a first face of the door and flanges extending on opposite edges thereof forming opposite side edges of the door, the flanges having a lid engaging surface spaced from the bottom surface, a lid having a top surface forming a second face of the door opposite the first face, opposite edges of the top surface each having a hem mated with a respective lid engaging surface of each flange, the hem including a portion of the top surface folded back on itself, and a plurality of welds securing the lid to the pan. The welds extend between the portion of the top surface of the lid folded back on itself of each hem and the respective lid engaging surface of each flange and are thereby concealed.
