Hollow core door apparatus for preventing the build up of pressure in a room having a register through which air flows into the room and the door includes an inside door skin and an outer door skin, and the door skins includes openings through which air flows into and out of the room and which openings have substantially the same area to provide for a non-linear flow of air through the door to prevent the build up of pressure in the room. An embodiment combining a noxious gas absorbent material with the pressure build up prevention capability is also illustrated.

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.

An adjustable sliding door system for building a sliding door for use in delimiting a part of a room in an opening and extending from the floor to the ceiling of the room is adapted to run in a track positioned opposite it on, respectively, the ceiling and the floor of the room. The adjustable sliding door system has two profiles constituting the sides of said sliding door and surface elements mounted between the profiles and constituting the surface of the sliding door. The adjustable sliding door system has a plurality of surface elements adapted to be mounted overlapping and in continuation of each other in a length corresponding to the height of the opening. This embodiment has the advantage that, based on few standard elements, a very flexible solution is obtained for building a sliding door of any height and where colors/decors may be varied according to personal desires.

The present invention is directed to a method of making a door having first and second door facings and an internal doorframe. An interior side of a first facing is coated with quick acting adhesive. A frame is placed on the coated interior side about the periphery of the first facing. The frame is then coated with quick acting adhesive. An interior side of a second facing is placed on the coated frame. The facings and frame assembly are then compressed to form a door. The present invention also provides for an automated system of making the door.

Molded articles are provided. An exemplary molded article includes an inner panel portion, a main body portion, and a contoured portion extending between and interconnecting the inner panel portion and the main body portion so as to surround the inner panel portion and be surrounded by the main body portion. The contoured portion includes contoured corner segments and contoured intermediate segments extending between respective pairs of the contoured corner segments. The contoured intermediate segments have a first maximum thickness. The contoured corner segments have a second maximum thickness. The first maximum thickness of the contoured intermediate segments is greater than the second maximum thickness of the contoured corner segments. Related methods, assemblies, and apparatus are also provided.

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 door having acoustical sound isolation properties includes a rail or stile having surfaces with a first, second and third planar portions stepped inward from and parallel to each other. Blocking layers are disposed parallel to and below one of the door surfaces, with each blocking layer having an edge with an extending flange contacting and extending along the second planar portion of the third surface of the stile or rail. The flanges of the blocking layers restrict movement of the layers toward each other. Soft acoustical material is disposed in the door interior. Flexible transition layers extend along the stile or rail third planar portions and extend over the blocking layers and the soft acoustical material to provide support against denting forces to the door.

The present invention is directed to a method of making a door having first and second door facings and an internal doorframe. An interior side of a first facing is coated with quick acting adhesive. A frame is placed on the coated interior side about the periphery of the first facing. The frame is then coated with quick acting adhesive. An interior side of a second facing is placed on the coated frame. The facings and frame assembly are then compressed to form a door. The present invention also provides for an automated system of making the door.

A method of manufacturing a hollow core door is disclosed, as wall as a corresponding hollow core door. The method includes the steps of providing a solid flat door skin, moisturizing the flat skin, applying a conditioning resin thereto, pre-heating the flat door skin, and thereafter pressing the flat door skin between a pair of heated platens in a press in order to reform the flat skin into a molded skin including a plurality of panels defined therein. The press continuously closes in order to reform the flat skin into the molded skin, with the rate of press closure being a function of the determined hardness of the flat skin to be reformed. The resulting door skins have an improved bond strength, and are efficiently manufactured.

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.
