This Architectural Drawing is Section of Door Framing Detail. An architrave is the piece of wood that goes around the door frame to cover the gap between the wall and the door frame. 32-1/2 inches. The rough framing should be 2-1/2 inches wider than the door itself. That leaves room for the 3/4 inch finish frame on each side of the door, and then 1/2 inch on each side for the shims between the finish frame and the rough frame. Many people confuse a door jamb and a door frame. Side jambs, head jambs, and mulls are the parts that make up the frame. Residential door frames are most often made of wood but can also be made of aluminum, fiberglass, or a composite material. Door frames can be purchased primed (ready to paint) or ordered with a factory finish in a variety of colors. A simple way to remember it is that a door jamb is part of a door frame. The flat surface that runs vertically up either side of the door frame is the jamb. For more details and information download the drawing file.
