Navigating the World of Doorway Terminology
Whether you’re a homeowner embarking on a renovation, a contractor tackling a new build, or an architect designing a dream home, clear communication is key. And when it comes to doorways, that means knowing your stuff. Understanding the precise names for all the parts of a doorway ensures everyone’s on the same page during design, construction, and repairs.
This article serves as your comprehensive guide to the names and functions of every component that makes up a doorway. We’ll dive into the anatomy of a door, from the frame that supports it to the hardware that allows it to function, and even touch on different door types and features.
So, whether you’re planning a DIY project, working in the construction industry, or simply curious about how doors are put together, this guide offers valuable insights. We’ll start with the core components of the doorway itself, then move on to the door leaf, and finally, we’ll cover the hardware and decorative elements that complete the look.
Let’s demystify the world of doorways, one part at a time and help you find the right names for parts of a doorway.
The doorway frame: The foundation
Before we get to the door itself, it’s important to understand the parts of the doorway frame. The frame is really the foundation that supports the door and allows it to function properly.
The rough opening: Preparing for installation
The rough opening is the framed opening in the wall where the door unit will be installed. It has to be the right size to accommodate the door frame and leave enough space for shimming and adjustments.
Typically, the rough opening is about 2″ taller and 2″ wider than the actual door unit. That extra space lets you level and secure the frame properly.
Key components of the door frame
The door frame is made up of several important parts, each with its own job to do:
- Jamb: These are the vertical pieces that line the sides of the opening. They give the door structural support and can be made of wood, metal, or composite materials.
- Head (Door Head): Also called the door head, this is the horizontal piece that goes across the top of the door frame. It connects the two jambs and gives the top of the doorway a finished look.
- Sill: The sill is the horizontal piece at the bottom of the door frame, providing a base for the door. For exterior doors, the sill is often sloped to help water run off.
- Threshold: This is the horizontal piece that bridges the gap at the bottom of the doorway, providing a transition between the interior and exterior floors. Exterior thresholds often have weatherstripping to seal the gap and block drafts.
The door leaf: construction and components
A door isn’t just a flat slab of wood or metal. It’s a carefully constructed unit, and each part has a name and a purpose.
Core components of the door slab
Let’s take a look at the parts that make up the main structure of the door:
Stiles: the vertical edges
The stiles are the vertical planks that run along each edge of the door. They’re what give the door its stability and provide a place to attach hardware like hinges and locks. Without strong stiles, your door wouldn’t be very secure.
Rails: the horizontal supports
Rails are the horizontal pieces that connect the stiles at the top, bottom, and sometimes in the middle of the door. They tie the whole structure together and add to its strength.
Panels: filling the space
Panels are the decorative or functional infills between the stiles and rails. They can be made of wood, glass, or composite materials. Panels can be flat, raised, or have decorative designs, and they contribute a lot to the door’s overall look.
Door core types: providing insulation and strength
The inside of a door is just as important as the outside. The core material determines how secure, soundproof, and insulated the door is.
Solid core: enhanced security and soundproofing
Solid core doors are filled with a solid material like wood, particleboard, or a composite. This makes them very secure and great at blocking out noise.
Hollow core: lightweight and economical
Hollow core doors have a honeycomb or other lightweight material inside, making them more affordable and easier to handle. These doors are fine for interior use where security isn’t a major concern.
Staved lumber core (SLC)
A staved lumber core is made of narrow strips of lumber glued together. By limiting the width of the lumber strips to around 2 1/2 inches, the manufacturer can create a stable core that’s less likely to warp or crack.
Glazing and lites: adding light and style
Many doors have glass panels to let light in or add a decorative touch.
Door-lite (lite)
A lite is simply a glazed opening in a door that allows light to pass through.
Faux lite
A faux lite looks like a glazed opening, but it’s purely decorative and not transparent.
Tempered glass: safety and durability
Tempered glass, also called safety glass, is designed to break into small, relatively harmless pieces if it shatters. This makes it a much safer option for doors than regular glass.
Door Hardware: Functionality and Security
Door hardware isn’t just decorative; it’s essential for a door’s functionality and security. Here’s a breakdown of the different components.
Hinges: Enabling Movement
Hinges are what allow a door to swing open and closed, connecting the door slab to the frame. There are several types:
- Barrel hinges: These are your standard, everyday hinges.
- Pivot hinges: These hinges allow a door to swing from a pivot point, often used for heavier doors.
- Concealed hinges: These are hidden when the door is closed, offering a clean, minimalist look.
- 3-D adjusted hinges: These hinges can be adjusted in three dimensions to ensure the door hangs perfectly straight and aligned.
- Non-mortise butterfly hinges: These decorative hinges don’t require a mortise (a recessed cut) for installation, making them easier to install.
Locking Mechanisms: Ensuring Security
The locking mechanism is what keeps your door securely closed.
- Lockset: This is the complete locking system, including the knob or lever, latch, and strike plate.
- Deadbolt: This provides an extra layer of security, typically operated with a key or thumb turn.
- Latch bolt: This is the part of the lock that extends from the door and engages with the strike plate, holding the door closed.
- Strike plate: This metal plate is mortised into the door frame, and the latch or bolt engages with it to secure the door.
- Mortise lockset: This type of lockset requires a pocket (mortise) to be cut into the edge of the door for installation. These are often found on older or high-security doors.
- Multi-point locking system: This system secures the door at multiple points along the frame, significantly enhancing security.
Handles and Knobs: Operation and Style
These are what you use to operate the door.
- Door handle: A lever-style handle used to open and close the door.
- Door knob: A round or oval knob used to operate the latch and open the door.
- Pull: A handle used to pull the door open, often found on screen doors or sliding doors.
Additional Hardware: Functionality and Convenience
These components add convenience and functionality.
- Door closer: A device that automatically closes the door after it’s opened, common in commercial settings.
- Magnetic catch (magnetic lock): A device that uses magnets to hold the door closed, often used on cabinet doors or closet doors.
- Door stop: A device that prevents the door from hitting the wall or other objects when opened.
- Flush bolt (dead bolt): A bolt that sits flush with the surface of the door when retracted, often used on inactive doors in a double-door setup.
Decorative elements and finishing touches
Beyond the basic structure, doorways offer plenty of opportunities to add visual interest and protect your home from the elements.
Moldings and trim: Enhancing aesthetics
Moldings and trim are your chance to add a personal flourish to your doorways.
- Casing: This is the decorative molding that goes around the door frame, hiding the space between the frame and the wall.
- Brickmould: This exterior trim surrounds the door frame. Brickmould is often used to create a nice-looking transition between the door and the outside wall.
- Crown entablature: This ornamental molding sits on top of the door frame and adds a touch of elegance.
- Baseboard (plinth): This decorative molding covers the joint where the wall meets the floor. It’s often matched to the door casing for a unified look.
- Wood molding: Decorative wood trim adds detail and visual interest to the door and the doorway.
Weather protection: Sealing the elements
Weather protection isn’t just practical; it can also contribute to the overall look of your doorway.
- Weatherstripping: Weatherstripping seals the gaps around the door to keep out drafts, water, and save energy.
- Door sweep: A door sweep attaches to the bottom of the door to seal the gap between the door and the threshold. This keeps out drafts and insects.
- Astragal: On double doors, an astragal is a vertical molding that seals the gap between the two doors when they’re closed.
Decorative glazing options
Glass can be a great way to add light and style to your doorway.
- Grilles: Grilles are decorative grids placed over the glass in a door.
- Muntin: A muntin is a strip of wood or metal that separates panes of glass in a door or window.
Door types: A brief overview
There are a surprising number of door styles out there. Here are a few of the more common ones:
In-swing vs. out-swing doors
The terms “in-swing” and “out-swing” simply describe which direction the door moves when you open it.
- In-swing door: This is a door that opens inward, into the room.
- Out-swing door: This is a door that opens outward, away from the room.
The choice between in-swing and out-swing usually comes down to space considerations and what’s allowed by local building codes.
Other common door types
- Barn door: A door that slides along a track. Barn doors are often used to create a rustic or modern look.
- Bifold door: A door that folds in sections when opened. Bifold doors are great for closets or other small spaces.
- Bypass door: A door that slides horizontally past another door. These are also commonly used for closets.
- French door: A door with multiple glass panes. French doors are often used in pairs to create a wide opening between rooms or to the outside.
- Louver door: A door with angled slats that allow air to circulate while still giving you privacy.
- Pocket door: A door that slides into a pocket in the wall when opened, saving space.
- Double acting door: A door that swings open in either direction.
