Must Know Door Terminology
Doors, we use them every day, but how well do you really know them? For experts in the trade, it’s important to know all the different types of doors and their features, so they can be constructed perfectly. Customers looking to install Special Purpose Doors for their business should also be informed on all of the parts that make up a door, so they can be sure they know exactly what they are looking for.
For those looking to install Special Purpose Doors for their business, it is important to first understand door terminology, as well as the parts and styles that are associated with different areas of installation. Here are some door terms, and where you will likely see them
General Door Terms
• Sliding doors – open side to side on a track, can come in both single and double sliding designs.
• Swinging doors – swing open on a hinge. In-swing doors open into a building while out-swing doors open away. These can also come as a double swinging door.
• Folding doors – can come either as a single or bi-folding door and fold like an accordion.
• Side by side doors – Also known as double doors or French doors, these are two swinging doors hung side by side.
• The Slab – this is the part of the door unit that moves within the frame.
• Active or inactive – active doors are commonly in use, while inactive doors are usually locked and do not move.
• The r-value – this is the door’s resistance to heat flow and describes a doors insulation effectiveness. The higher the value the better the door’s resistance.
Door Frame Terms
The frame of a door is just as essential as the main slab which moves within it. Here are some terms that describe door frames:
• The casing – this is an aesthetic moulding that encases the opening.
• The jambs – the sides of the frame that attach to the door slab via hinges.
• The stop – this runs along the frame’s perimeter and stops your door from swinging too far.
• The threshold – also called the sill, this sits below where the door is hung
• Transoms – decorative glass panels above the door
• Sidelights – decorative glass panels to the side of the door
Swinging Doors Terms
Swinging doors are the most common type of door. They are the main choice for entryways, where they provide a barrier between a building and the outside world, so it’s important for them to be strong and to insulate against the elements. Swinging doors can come in both single and double size, which are both suited for different uses.
There are specific parts and terminologies that are specific to swinging doors, here are some common terms that you might come across:
• Glass inserts – these are slabs of glass inlaid into the door for decorative purposes.
• Panels – raised or recessed sections, also installed for decorative purposes.
• Rails – horizontal panels, however, there are different types depending on their location. The top is called the top rail, the bottom is called the bottom rail, while the lock rail runs where the lock is located.
• Stiles – the vertical panels on a door, similarly to rails, there are top, bottom and rail stiles.
• Weatherstripping – a foam strip that insulates against drafts.
• Lockset – the system that keeps your door locked.
• Right hanging or left hanging – refers to the side of the door that the hinges are on.
Sliding Doors Terms
Sliding doors are different from swinging doors as they slide along railes, rather than swing from a hinge. They are also usually used in different areas and for different purposes, and their designs make them effective for high traffic solutions. Sliding doors are built differently to other doors, so they have a few unique parts that only apply to them:
• The sliding panel – the panel that moves.
• The fixed panel – the panel that stays in place.
• Tracks – the panels slide within a track. A lower track runs along the bottom and upper track on the top.
• The latch – the mechanism that unlocks the door.
