A core for a fire rated door includes a fire resistant center panel and an extruded fire resistant border. The fire resistant center panel has a bottom, a top, a first side, a second side, a first end and a second end. The fire resistant center panel is made of a first fire resistant material. The extruded fire resistant border is attached to the first side, the second side, the first end and the second end of the fire resistant center panel. The extruded fire resistant border is made of a second fire resistant material having a higher density than the first fire resistant material.

A system and method for making a door having first and second door skins and an internal frame. The top and bottom surfaces of the frame are coated with an adhesive and the frame is placed on a first door skin. The second door skin is then placed on the opposite surface of the frame. The assembled components are then pressed to bond the first and second door skins to the frame with a pressed having platens. Movable shims may be used to vary the pressed force and pressing area.

A door pressing system for pressing interior passage doors, exterior entry doors, bi-fold doors, and/or closet doors features a multi-door pressing station including first and second presses, a loading device, and a discharging device. The pressing station is configured to alternatively move the first and second presses into operative alignment with the loading and discharging devices. The press in operative alignment delivers a pressed assembled door to the discharging device and receives an assembled door layup to be pressed from the loading device. The other press that is out of operatively alignment presses an assembled door received therein. Additional methods and systems are also provided.

The present disclosure relates to the technical field of door processing, and in particular to a door with a plastic-wood co-extruded skeleton and a processing method thereof. The door includes a door skeleton, including four multilayer boards; where the four multilayer boards form a rectangular frame structure; an outer surface of each multilayer board is wrapped with a PVC wrapping layer, and an outer side of the PVC wrapping layer is attached to an SMC door skin; a PU filling foam is filled between an outer periphery of the door skeleton and a wall structure outside the door skeleton.

A soundproof door assembly for use in reduction of sound transmitted from one side of the door to the other side, having an STC number at least STC 36 determined in accordance with ASTM E413-10 and E90-09, comprising a soundproof door having a thickness of 30-80 mm, which comprising two door skins, one formed as a front door skin and the other formed as a rear door skin for the soundproof door respectively; a quadrilateral frame, constituted by a top rail member, a bottom rail member, a left stile member and a right stile member to seal the perimeter of the door skins; and a multiple-layered core, to form a concrete inner portion of the door, which comprising three layers of a hard-soundproof material that blocks sound with high frequency over 500 Hz, wherein each of the door skins includes an aperture aligned and devoid of any soundproofing core thereby forms a window of the soundproof door for accommodation of a glass pane.

A plurality of stacked door skins is provided, the plurality including at least first and second door skins each including at least one inner panel, an outer body portion surrounding the at least one inner panel, and at least one contoured portion surrounding the at least one panel and interconnecting the at least one panel to the outer body portion. The at least one contoured portion includes a substantially V-shaped indent area adjacent to and within the outer body portion, a planar area that is substantially parallel to the outer body portion and is adjacent to and within the substantially V-shaped indent area, and a declining area adjacent to and within the planar area and terminating at the inner panel.

A ventilator door brings fresh outside air into a structure through an outside opening and a fan or blower pulls outside air into a duct in the door. The air flows through the duct and into the structure through an inside grill remote from the outside opening. Heat is transferred from the flow of air to a heat sink disposed in the duct to cool the fresh air flowing into the duct. A regenerative heat sink may be used to capture heat from a flow of air from inside the structure and transfer the captured heat to a flow of outside air flowing into the structure. An inside opening in the door generally opposite to the outside opening. The air flow through the openings is controlled by movable panels by aligning or by misaligning openings in the movable panels with the openings in the outside and inside panels. A microprocessor controls the movable panels and the fan or blower in response to sensors inside and outside of the door.

A door skin is provided that includes at least one inner panel, an outer body portion surrounding the at least one inner panel, and at least one contoured portion surrounding the at least one panel and interconnecting the at least one panel to the outer body portion. The at least one contoured portion includes a substantially V-shaped indent area adjacent to and within the outer body portion, a planar area that is substantially parallel to the outer body portion and is adjacent to and within the substantially V-shaped indent area, and a declining area adjacent to and within the planar area and terminating at the inner panel. A door including at least one door skins and a doorframe is also provided.

A security door hinge assembly is provided, comprising a door frame structure, having at least a head member, a first jamb member and a second jamb member, and at least one door leaf. The door leaf further comprises a leaf frame structure, having at least a top rail member, a bottom rail member, a hinge stile member and a lock stile member; an inner leaf panel, mounted to a first side of said leaf frame structure and extending past said hinge stile member, so as to form an inner leaf flange; an outer leaf panel, mounted to a second side of said leaf frame structure, opposite said first side, and extending past said hinge stile member, so as to form an outer leaf flange, and wherein, in use, said door leaf is operable between a first closed position and a second open position. The security door hinge assembly further comprises a hinge chamber positioned between said first jamb member and said hinge stile; a hinge-mount bracket, coupled to said first jamb member; a hinge mechanism, having at least one pivot axis and which is located within said open hinge chamber and adapted to pivotally mount said door leaf to said hinge-mount bracket, and wherein, in said first closed position, said inner leaf flange is in an exteriorly overlapping engagement with at least a portion of said hinge mount bracket, so as to prevent access to said hinge mechanism.

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.
