What Are Double Doors Called? Find The Right Term For Your Entryway

When architects, contractors, and homeowners discuss interior and exterior access points, the question often arises regarding what double doors are called. While the simple answer is often "double doors," the specific terminology can vary based on function, design, and placement. Understanding the distinct names for these paired entries is essential for anyone involved in construction, renovation, or selling a property, as it clarifies communication and ensures the correct hardware and installation methods are specified.

Defining Double Doors

The term "double doors" refers to a pair of door leaves that operate together to create a single, large opening. These doors can be configured in several ways, but the two most common are the "closer and jamb" setup and the "Dutch door" variation. In a standard closer and jamb configuration, two doors are mounted on a single frame, with one typically operating as the primary access point while the other is passive. This setup is dictated by the hardware, specifically the hinges and the alignment of the door frames, which must be precise to allow the two leaves to move symmetrically.

Single Double vs. French Doors

It is important to distinguish between a true "single double" door and a "French door." While both involve two panels, the construction differs significantly. A single double door consists of two solid panels that operate as one unit, usually leading from a hallway into a kitchen or from a lobby into an office. Conversely, French doors are characterized by large panels of glass set within a wooden or metal frame. If the glass panels are the primary component and they open outward or slide, they are classified as French doors, not standard double doors, although the function of providing wide entry is similar.

Architectural and Functional Classifications

Beyond the basic mechanics, double doors are categorized by their role within a building's envelope. An entry that faces the exterior and is designed to handle weather, security, and high traffic is often referred to as an "external double entrance" or "front double doors." These usually incorporate security features and may include a transom window above. In contrast, interior passages might utilize "double pocket doors," which slide into the wall to save space, or "double barn doors," which are mounted on exposed tracks for a rustic or modern aesthetic.

• Exterior Double Entrance: The primary point of entry for a building.
• Double Pocket Doors: Interior doors that slide into the wall cavity.
• Double Barn Doors: Sliding doors often used for decorative purposes.
• Double Revolving Doors: Used in high-traffic commercial buildings for climate control and security.

The Role of Thresholds and Hardware

The specific name of a double door setup is often linked to its threshold and hardware. A "double sliding door" requires a specific track, while a "double folding door" uses hinges that allow the panels to fold like an accordion. In commercial settings, the term "double wide door" is frequently used in specifications to differentiate the opening size from standard single access doors. This precise language ensures that contractors order the correct astragals, handles, and safety mechanisms required for the opening.

Aesthetic and Design Considerations

Homeowners and designers frequently seek specific terminology when looking to enhance curb appeal or maximize interior light. For glass double doors, the term "double glazed door" refers to the insulation properties of the glass, which features two panes with a gas-filled spacer. For wood frames, the look might be described as "board and batten double doors," which refers to the vertical grooved panels overlain by narrow strips. Knowing these terms helps in searching for inspiration and ensuring the final product matches the intended vision.

Historical and Specialty Names

Historically, large double doors were often called "coach doors" because they were standard in horse-drawn carriages and early automobiles, designed to allow easy entry and exit. In modern real estate, you might encounter the term "grand entrance" to describe a dramatic double door foyer in a luxury home. While these are not technical classifications, they are part of the vernacular used to describe the function and feel of the space, indicating significance and grandeur rather than just utility.
