A fire door with a frame for arrangement is provided in a wall opening with an opening plane, at least one fire door leaf to be opened at least in sections along an opening normal of the opening plane for fire-retardant closure of the wall opening, at least one vacuum insulation panel for reducing heat transport through the fire door leaf along the opening normal in a closed state of the fire door, and at least one leaf sealing element which connects the frame to the fire door leaf in a wind-tight manner in a closed state of the fire door. The leaf sealing element defines a leaf sealing plane in a closed state of the fire door, which is arranged parallel to the opening plane. A frame and a manufacturing method for the fire door is also provided.

Provided is a system and method of 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 press having upper and lower dies configured to impart a larger compression force toward a central area of the door skins. Wear resistant belts or membranes are provided to protect the door skins from being marred by the upper and lower dies during the pressing process.

A door for attenuating sound includes at least one core disposed between a front surface and a back surface. The at least one core includes a composition comprising vermiculite, for example, expanded vermiculite, and an inorganic bonding agent. Such a composition for the core has a density of at least 600 Kg/m.sup.3. The door has at least a sound transmission class (STC) rating or an outdoors/indoors transmission coefficient (OITC) being higher than 30.

The present invention relates to shaker doors with solid cores and methods for making the same. The shaker doors contain different core materials at the recessed panel than the raise peripheral region to provide dimensional stability and reduced distortion when the doors are exposed to high humidity. The devices and methods also provide for easy assembly of solid core shaker doors, including fire rated doors.
