The door panel is pivotal in providing access, privacy, and security, making it a fundamental component of front doors.

Jamb of the Front Doors

Within the realm of front door components, the door jamb plays a crucial role as a vertical section running along the sides of the door frame. It provides structural support and stability to the door, reinforcing its integrity. Positioned perpendicular to the door panel, the door jamb ensures proper alignment and facilitates smooth opening and closing of the door. The door jamb is an integral part of the overall framework, contributing to the durability and functionality of front doors.

Front Door Still

When examining the parts of front doors, the sill takes its place as a crucial part located at the bottom of the door frame. Positioned horizontally, it rests flush against the floor, providing a stable base for the door.

The sill serves multiple functions, including acting as a threshold, sealing the gap between the interior and exterior, and preventing drafts, water, and debris from entering the space.

It plays a pivotal role in maintaining front doors’ integrity, insulation, and overall functionality.

Entry Doors Threshold

Located at the bottom of the door frame, the threshold is a barrier to keep wind, water, and external elements from entering your home. It features a slight slope towards the outside, facilitating proper drainage and preventing water accumulation.

The threshold acts as a strong defence against the elements, enhancing the insulation and weatherproofing of your front door, ultimately contributing to a comfortable and secure living environment.

Rail of Entry Doors

Often employed as decorative elements, they can divide the door into distinct sections.

Rails serve both functional and aesthetic purposes, enhancing the door’s overall design and visual appeal. With their decorative potential, they contribute to the door’s style and character, allowing for creative variations and customization.

By incorporating rails, front doors can be transformed into visually captivating and structurally engaging architectural design elements.

Positioned at the bottom, the door sweep lies flat against the threshold, creating a secure barrier against drafts and external conditions. By maintaining a tight seal, the door sweep enhances the overall weatherproofing and insulation of the door, contributing to a comfortable and protected interior environment.

Out-Swing or In-Swing

In-swing doors are designed to open into the room, meaning that when you are inside your home, they are pulled towards you when you open them. On the other hand, out-swing doors open towards the exterior, so when you are inside your home, they are pushed away from your body when opening.

These two types of door swings provide different door placement and functionality options, allowing for flexibility in design and space utilization.

Astragal for Double Front Doors

In front door designs incorporating double doors, an astragal is a vertical piece that runs between the panels.

By serving as both a decorative and functional element, these parts of the front doors aid in establishing an aesthetically pleasing division between the doors.

The astragal provides structural support and enhances the overall stability of the double door system.

Additionally, it helps to improve insulation and weatherproofing by minimizing drafts and preventing the ingress of external elements. The astragal is an essential component in the construction and aesthetics of front double doors.

Glass or Glazing

Glazing also called the glass in a front door, is the window-like feature within the door itself. Its primary purpose is to allow natural light to enter the space and brighten the doorway.

Typically, the glass in a front door consists of two panes, providing insulation and enhancing energy efficiency. The glazing not only adds aesthetic appeal but also contributes to the overall functionality and ambiance of the entrance, creating a welcoming and well-lit atmosphere.

Sidelights of Your Front Doors

Sidelights are stationary windows affixed to an entry door’s sides. They are commonly characterized by their tall and narrow design, serving to enhance the architectural appeal of the front of your home.

Sidelights play a dual role by adding visual interest and allowing natural light to illuminate the entryway. By incorporating sidelights, you can create a brighter and more inviting atmosphere while simultaneously accentuating the aesthetic charm of your home’s facade.

Entry Door’s Transoms

A transom is a stationary glass window installed above the door and sidelights. Positioned horizontally, it is an architectural feature that allows ample natural light to enter your entryway. By incorporating a transom, you can enhance the brightness of your entry while adding a touch of elegance to the overall design. Transoms contribute to a well-lit and welcoming atmosphere, creating a visually appealing focal point above the door and sidelights.


Grilles are decorative elements that are used to create the appearance of divided lites in front doors. They can be positioned between the panes of insulating glass, known as grilles-between-the-glass, or installed on the outside of the glass.

Grilles add design interest and allow you to customize the look of your front door. By incorporating grilles, you can achieve a traditional or classic aesthetic reminiscent of doors with individual divided glass panes. Grilles contribute to the overall visual appeal of the door, providing a distinct and personalized touch to its appearance.
