Door Components

Door Frame

A door frame is the essential structure that supports and secures the door, ensuring it operates smoothly and remains aligned. It consists of three main parts: the head (top horizontal component), the jambs (vertical sides), and the sill (bottom horizontal component).

Exterior door frames are particularly crucial as they provide protection against weather elements and enhance security. These frames can be crafted from various materials, including wood, aluminum, fiberglass, and composite materials, each offering different benefits in terms of durability and maintenance. Whether primed or factory-finished, exterior door frames come in a range of colors to match your home’s aesthetic.

Door Panel

The door panel, often referred to as a slab, is the main body of the door that swings open and closed. It can be a single solid piece or divided into smaller sections by stiles (vertical components), rails (horizontal components), and mullions (vertical or horizontal bars between panels).

Door panels are made from a variety of materials, such as wood, metal, and composite materials, each chosen for their specific properties like durability, insulation, and aesthetic appeal. Exterior door panels are designed to withstand harsh weather conditions while providing security and energy efficiency.

Door Jamb

The door jamb is a critical part of the door frame, consisting of the vertical sections on either side of the door opening. There are two side jambs and a head jamb, which is the top horizontal part. Together, these components form the supportive structure that holds the door in place.

Door jambs can be made from materials like wood, aluminum, fiberglass, and composite materials, chosen for their strength and resistance to wear. Properly installed door jambs ensure that the door operates smoothly and securely.

Door Hardware

Hinges

Hinges and locksets are vital components of door hardware, ensuring both functionality and security. Hinges are the metal parts that attach the door to the door frame, allowing it to pivot open and closed. They come in various styles and finishes to match the door’s design and ensure smooth operation.

Locksets

Locksets are the mechanisms that secure the door. A typical lockset includes a lock, latch, and strike plate. The lock stile is the vertical part of the door panel that houses the locking mechanism.

For added security, a metal plate installed on the door frame, known as a strike plate, reinforces the area where the latch engages, protecting against forced entry. Exterior door hardware is specifically designed to endure weather conditions while providing robust security and ease of use.

Door Comparison

Entry vs. Patio Doors

Entry doors excel in security, insulation, and curb appeal, often made of sturdy materials like steel or fiberglass. Patio doors, by contrast, emphasize functionality and natural light with glass-dominant designs. While entry doors protect and impress, patio doors connect and illuminate.

Solid Wood Doors vs. Hollow Core Doors

Solid wood doors offer unmatched durability, insulation, and elegance, suitable for premium interiors and exteriors. Hollow core doors are lightweight, affordable, and easy to install, making them ideal for low-traffic interior spaces. While solid wood doors excel in longevity, hollow core doors provide budget-friendly functionality.

Steel vs. Fiberglass Doors

Steel doors provide superior security and durability, making them a top choice for entryways. Fiberglass doors balance durability with aesthetic versatility, often mimicking wood textures while requiring less maintenance.

How to Install a Door

Installing a door requires precision, preparation, and the right tools to ensure a professional finish. Whether you are working with prehung doors, slab doors, or specialty doors like barn doors, having the appropriate equipment is crucial.
