Door Frame Parts

Door frames are an essential part of any building's structure, providing support, stability, and security to doors. 

While most people are familiar with the basic concept of a door frame, understanding its various components can be beneficial for maintenance, repair, or installation purposes.

Header:

The header is a horizontal component that spans the top of the door frame. It distributes the weight of the structure evenly, ensuring stability and load-bearing capacity. 

Headers are typically made of wood, steel, or engineered materials, depending on the specific requirements and building codes.

Jamb:

The jambs are vertical components that form the sides of the door frame. There are two jambs: the hinge jamb and the strike jamb. 

The hinge jamb houses the hinges, allowing the door to swing open and closed. The strike jamb, on the other hand, includes the strike plate and latch, providing a secure closing mechanism.

Threshold:

The threshold is the bottom part of the door frame, forming the transition between the interior and exterior spaces.

It helps to seal the gap between the door and the floor, preventing drafts, water, and insects from entering. Thresholds are commonly made of metal, wood, or a combination of both.

Casing:

The casing, also known as trim or molding, is the decorative finishing component that surrounds the door frame. It enhances the aesthetic appeal and covers the joint between the frame and the adjacent wall. Casings can be simple and minimalistic or ornate, depending on the architectural style and personal preference.

Weatherstripping:

Weatherstripping is a crucial part of the door frame, especially for exterior doors. It is a sealant that prevents air leakage, drafts, and moisture infiltration. 

Weatherstripping materials vary but often include rubber, vinyl, or foam strips that are installed along the edges of the frame, creating a tight seal when the door is closed.

Hinges:

Hinges are the movable joints that allow the door to swing open and closed. They are typically attached to the hinge jamb and the door itself, providing stability and smooth operation. 

Hinges come in various types, including butt hinges, continuous hinges, and pivot hinges, each suitable for different door applications.

Strike Plate and Latch:

The strike plate and latch are essential components of the strike jamb, responsible for securing the door in the closed position. 

The latch extends from the door and engages with the strike plate when the door is closed, keeping it in place. The strike plate reinforces the area where the latch engages, ensuring a secure locking mechanism.

What Is the Edge of a Door Frame Called?

The edge of a door frame is typically referred to as the "door jamb." The door jamb is the vertical portion of the frame that the door is attached to, forming the sides of the door opening. 

It provides structural support and helps keep the door in place when closed. The horizontal part of the frame, which forms the top of the door opening, is called the "header" or "lintel."

What Is a Door Flange?

A "door flange" is not a standard term used in the context of doors or door frames. It does not have a widely recognized meaning or definition. 

It's possible that the term you're referring to is either a regional or industry-specific term, or it may be a miscommunication or a term used in a specific context that is not widely known. If you provide more information about the specific context or usage of the term, I can try to help you further.

What Is the Gap Around a Door Called?

The gap around a door is commonly referred to as the "door clearance" or "door gap." It is the space between the door and the door frame when the door is closed. 

The gap allows for smooth operation of the door, accommodating for factors such as swelling due to temperature or humidity changes. It also helps with noise reduction, as well as providing a barrier against drafts and maintaining privacy.

What Is a Door Escutcheon Plate?

A door escutcheon plate, also known simply as an "escutcheon," is a decorative or protective plate that is installed around a door lock or keyhole. 

It is typically made of metal or another durable material and is designed to cover the hole in the door where the lock or key cylinder is inserted.

The escutcheon plate serves multiple purposes. Firstly, it provides an aesthetically pleasing cover for the lock mechanism, enhancing the overall appearance of the door. 

Additionally, it helps protect the surrounding area of the door from wear, tear, and damage that may be caused by the repeated insertion and removal of keys or by general use over time.

Escutcheon plates come in various styles, shapes, and finishes to match different door designs and architectural aesthetics.

They can be found on both interior and exterior doors, and their installation is typically straightforward, involving attaching the plate to the door using screws or other fasteners.
