Types of Interior Door Frames

Before we discuss the types of Interior Door Frames, let us understand what the various components are. We will see that Beams are horizontal and transfer the weight of the opening above to jack studs. Then, we will learn about Lintels and headers, which transfer the load from the opening above to the jack studs. We will also see Astragals, which are vertical pieces of wood that form the center of the flush wall door opening.

Beams are horizontal in shape

Lintels and headers are the two structural pieces above the door frame. Lintels are found above door frames, window frames, garage doors, chimneys, and portals. Headers are commonly found above skylights and chimneys. Both of these structural elements are made of lumber or plaster moldings. Beams are generally shorter than headers. They serve the same purpose as headers. A double-wide header can hold the weight of a door opening ranging from four to six feet.

Beams are horizontal in shape and provide structural support. They are used on various parts of the house and in different types of structures. Beams are common on exterior door frames and in bearing walls. They transfer the load from the opening above to jack studs. Beams are a crucial part of the home’s framing system. If you’re planning to install an interior door frame, there are a few things you should know about beams.

Lintels and headers transfer the load from the opening above to the jack studs

Lintels and headers are horizontal elements above load-bearing walls. Often called headers, they are generally located at the exterior of the building. They consist of two pieces of lumber nailed together. They are designed to carry the weight of the door from the opening above to the exterior of the building. They come in two types, two-ply and three-ply. Many contractors opt for three-ply lintels.

In building exterior walls, cripples and headers should be installed at a distance of 73 inches above the bottom of the wall panel. These headers should be nailed using 16d sinkers and should extend at least 1/2 inch (13 mm) beyond the bottom of the wall panel. When installing interior doors, be sure to match the size and style of the prints with the jack studs and cripples.

Cripple studs are the mortise on one of the side jambs

Interior door frames have three basic parts, the top jamb, side chamfers, and side studs. A top jamb is 11/16 inches thick, while a side jamb is four to nine inches wide. The two are attached by heavy pieces of material laid on their edges horizontally to provide floor and ceiling support. The interior door’s hardware includes a latch bolt and a knob. Several of these pieces are called passage sets. Some of these doors also have a lock block, which is glued inside the door.

The mortise is a part of an interior door frame that serves as a support for the door itself. It’s located on a side jamb. If the door has a jack stud installed, it will support a header. The header is a horizontal piece of lumber that matches the stud width. A header can be two to twelve inches wide.

Astragal is a vertical piece of wood in the middle of the door opening

The Astragal is a vertical piece of wooden material that runs the full length of the door panel and protects the internal mechanisms of the door. Astragals are usually made of wood or aluminum but are sometimes made of a combination of both materials. The purpose of the Astragal is to provide a seal between the door and its frame, preventing the door from tipping over.

Astragals are often used in pairs of doors to prevent drafts. In addition to helping to keep out air leaks, they also prevent noise and moisture from entering the room. Because they are typically made of wood or metal, Astragals are also designed to dampen the sound of the closing door. However, they should not overlap with double vertical rod applications. An Astragal is not required for every type of door, though, so they are often used in conjunction with weatherstripping.

Options for casing

Interior doors with multiple layers are often considered a decorative design element and may be dressed up with different types of the casing. One of the most popular casing styles is the Colonial. There are other styles available, but they aren’t as elaborate as the Colonial. In fact, some people prefer the simpler Belly or Stafford style. There are also many different types of casing, including composite materials. Choose the one that best complements the style of your home.

There are two main styles of the casing for interior doors: molded and flat. Both types of casing join together in the butt or miter joints. Both types of the casing have to fit flat and be level with the door jamb. The butt style is ideal for homes with high ceilings. This style is less bulky than the mitered style and matches the depth of the base trim. You can use either type for your interior doors.


Whether you’re replacing an old, damaged hinge, or installing a new one, you need to learn about the different types of doors. A door hinge is a piece of hardware that attaches the door to its frame. This mechanism is usually made of two leafs, joined together by a pin. The leaves are attached to the frame and door by screws, and the pins are held together by knuckles.

When installing new hinges, you first need to make sure they’re plumb. You’ll need to measure the depth of each jamb from the bottom to the center of each hinge. Then, mark the location of each hinge with a level, then take it to the face of the frame. After making sure the door frame is square, reposition the hinges. Then, make sure the door is plumb by using a level to align the faces of the door frame and the casing.
