A door has a core that includes a first major surface having one or more first recesses, a second major surface opposite to the first major surface, and fire retardant material such as intumescent material applied to the first recesses and no more than about 20 percent by surface area of a remainder of the first major surface excluding the first recesses. A door skin includes an interior surface, an exterior surface, at least one contoured panel portion establishing a protrusion extending on the interior surface and an opposite depression extending into the exterior surface, and fire retardant material such as intumescent material applied to at least one of the protrusion or the depression and no more than about 20 percent by surface area of the remainders of the interior surface excluding the protrusion and the exterior surface excluding the depression.

A fire rated door includes a core, a first decorative panel and a second decorative panel. The core includes: (a) a gypsum-based fire resistant center panel having a bottom, a top, a first side, a second side, a first end and a second end, wherein the gypsum-based fire resistant center panel is made of a first gypsum-based fire resistant material, and (b) an extruded gypsum-based fire resistant border attached to the first side, the second side, the first end and the second end of the gypsum-based fire resistant center panel, wherein the extruded gypsum-based fire resistant border is made of a second gypsum-based fire resistant material having a higher density than the first gypsum-based fire resistant material. The first decorative panel is attached to the top of the gypsum-based fire resistant center panel and the extruded gypsum-based fire resistant border. The second decorative panel is attached to the bottom of the gypsum-based fire resistant center panel and the extruded gypsum-based fire resistant border.

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.

A door for rail vehicle has a frame-type door main body and covering metal sheets. The door main body is formed of profiled elements, which are connected to each other by way of corner connectors. The covering metal sheets are arranged on two opposite sides of the door main body. The profiled elements are connected to each other exclusively by way of a fixed but releasable connection by the corner connectors. A fire protection material is arranged between at least one covering metal sheet and the frame-type door main body in such a way that the fire resistance and the thermal insulation of the rail vehicle door are increased.

A swinging type fire door includes a frame having opposite top and bottom walls and opposite first and second side walls each extending from the top wall to the bottom wall. A first tube is coupled to the top wall. A second tube is coupled to the bottom wall. An inner wall has a first end coupled to the first tube and a second end coupled to the second tube. A filler material is positioned between the inner wall and at least one of the side walls.
