Introduction of Door Frame

Important Point

A door frame is basically a type of framework that supports the door and it includes parts of a door frame like sill, side jambs, head jambs, etc.

Wooden or timber material is used to construct the door frame most of the time.

In, modern days various other materials are also used to construct the door frames such as fiberglass, aluminum, composite materials, etc.

Technically, a door frame is a combination of horizontal and vertical members that support the whole door.

Generally, in the door frame, a border has been provided to make it more attractive and beautiful.

The door frame is opted according to the size of the opening of the door. Basically, the cost of the door frame depends on the size of the door, if the door is larger then the cost of the door frame is also increased.

Parts of Door Frame

The door frames have different members, their characteristics are also different

1. Sill

The sill is one of the important portions of the door frame. The sill is fastened or sealed with the door.

The main advantage of using a sill is it prevents the bending of vertical door members’ frames after the construction.

Sill also has different advantages like it prevents dust & entry of insects inside the room under the door.

Sill also has a few disadvantages which is it creates an obstruction in the time of cleaning or moving.

2. Door Jambs

Door jambs are also a very vital member of the door frame. Door jambs are basically two vertical members that support the door openings.

There are also side jambs which are attached to the face of the door for opening and locking.

3. Head Jambs

The head jamb is also a horizontal member which is situated at the top of the door frame. Head jambs hold the whole structure from the top of the frame.

4. Horn

The horn is another member of the door frame which is the horizontal projection of the top and bottom portion.

The main advantage of using a horn is it fixes the door frame in the wall opening.

The threshold is a piece of wood that is placed at the portion of the floor and the bottom of the door.

Threshold also helps to drain out the rainwater at the outside direction to open and close the door easily.

Standard Size Door Frames

The door frame size depends upon the size of the door, if the door size is big then the frame size is also larger and if the door size is small then the size of the door frame will also be less.

If we consider the standard size of the door is 6 ft 8 inches (not considering the door frame width) then the door frame will cover some extra space.

Naturally, the door frame is wider than the door openings. The width of the door frame post varies between 2 to 4 inches. So, the total width of the door frame is-

Total width of door frame = Width of door frame + width of door + width of door frame

Which is,

Total width of door frame = 2” + 36” + 2”
Total width of door frame = 40”
The calculation of the height of the door frame is the same as the previous one-
Height of door frame = Height of door + width of door frame
Height of door frame = 6’8” + 2”
Height of door frame = 6’10”
So, the overall size of the door frame is 82” x 40”
