Components of Doorways
When framed in wood for snug fitting of a door, the doorway consistsof two verticaljambs on either side, a lintelorhead jamb at the top,and perhaps a thresholdat the bottom. When a door has more thanone movable section, one of the sections may be called a leaf.
Lintel - A horizontal beam above a door that supports the wallabove it. (Also known as a header)
Jambs - The vertical posts that form the sides of a door frame,where the hinges are mounted, and with which the bolt interacts.
Sill - A horizontal beam below the door that supports the frame
Doorstop - a thin slat built inside the frame to prevent a door fromswinging through when closed, which might break the hinges.
Architrave - The decorative molding that outlines a door frame.(called an Archivolt if the door is arched). Called doorcasingorbrickmoldin North America.

Materials Used on Doors
A hollow-core flush interiordoor is a common choice for newconstruction.
It has a frame made of solid wood
boards that are typically about 11/2 inches wide. A cardboardwebbing runs through the interiorto provide rigidity and prevent
drumming. These doors can last for decades if
treated gently, but can be dentedor punctured if hit hard.

Materials Used on Doors The most affordable choice is a
stamped hardboard interiordoor. The hardboard (sometimescalled by the brand name Masonite) isa fairly soft material, but is usuallycovered with a hard-baked paint.
Some hardboard doors are hollow-core, while others are filled with foamor particleboard. These can look greatfor years if treated gently, but they are
easily dented; if they become wet forprolonged periods, the hardboard willswell.
Both conditions are difficult to repair.

Materials Used on Doors
A solid-core flush exterior door is
made much like a hollow-core interior
door, but the space within the wood
frame is filled with solid particleboard.
These are very heavy but not as
durable as other exterior doors. If notkept protected with paint, the veneer
may delaminate from the
particleboard.
If the particle board gets wet, the doorcan become unusable.

Materials Used on Doors
Insulated Wooden-panel doors, made
for interior and exterior applications, havea classic appeal.
Solid wood has good strength and
insulating properties. Hardwoods such as
oak are very resistant to denting;softwoods such as pine are more easily
dented but are still quite durable.
All exterior doors must be protected with
paint or finish to prevent them from
warping or cracking. Some exterior wood-panel doors have a foam core, for added
insulation and stability.

Materials Used on Doors A stave-core (also called "core-
block") exterior door looks like a
standard wood-panel door, but it is
made of several thin pieces of wood
that are laminated together.
The laminated core is then covered
with a wooden veneer. This method
makes for an extremely stable door.
However the veneer is liable to peel if
the door is not kept protected with
stain or paint.

Once considered an option only for

Some have a steel face with a
foam core for insulation. Othershave a core made of foamwrapped in steel, with a woodveneer applied to the exterior.
The result is a door with goodinsulating properties that is alsovery strong and burglar resistant.

Glass-panel doors need to bewell built, especially if they are
exterior doors.
Individual glass panes are often
referred to as "lights" (or "lites"). Be sure to get gas-filled thermal
glass panes for an exterior door,
and make sure the glass is well
sealed against the stiles and
rails.

A flush door is a completely smooth door,having plywood or MDF fixed over a light
timber frame, the hollow parts of which are
often filled with a cardboard core material.
Skins can also be made out of hardboards,
the first of which was invented by William HMason in 1924.
Called Masonite, its construction involved
pressing and steaming wood chips into
boards. Flush doors are most commonly
employed in the interior of a dwelling,although slightly more substantial versions
are occasionally used as exterior doors,
especially within hotels and other buildings
containing many independent dwellings.

Components of a Flushed Door
Many modern doors, including most interior doors, are flush doors: Stiles and rails - As above, but usually smaller. They form the outside edges of the door.
Core material: Material within the door used simply to fill space, provide rigidity and reduce
druminess.
Hollow-core - Often consists of a lattice or honeycomb made of corrugated cardboard, or thin wooden
slats. Can also be built with staggered wooden blocks. Hollow-core flush doors are commonly used as
interior doors.
Lock block - A solid block of wood mounted within a hollow-core flush door near the bolt to provide asolid and stable location for mounting the door's hardware.
Stave-core - Consists of wooden slats stacked upon one another in a manner similar to a plank &
batten door (though the slats are usually thinner) or the wooden-block hollow-core (except that the
space is entirely filled).
Solid-core - Can consist of low-density particle board or foam used to completely fill the space within
the door. Solid-core flush doors (especially foam-core ones) are commonly used as exterior doors
because they provide more insulation and strength.
Skin - The front and back faces of the door are then covered with wood veneer, thin plywood, sheet
metal, fiberglass, or vinyl. The wooden materials are usually layered with the grain alternating direction
between layers to prevent warping. Fiberglass and metal-faced doors are sometimes given a layer of
cellulose so that they may be stained to look like real wood.

Components of a Panel Door
Stiles - Vertical boards that run the full height of a door and compose itsright and left edges. The hinges are mounted to the fixed side (known asthe "hanging stile"), and the handle, lock, bolt, and/or latch are mountedon the swinging side (known as the "latch stile").
Rails - Horizontal boards at the top, bottom, and optionally in the middleof a door that join the two stiles and split the door into two or more rows ofpanels. The "top rail" and "bottom rail" are named for their positions. The
bottom rail is also known as "kick rail". A middle rail at the height of the
bolt is known as the "lock rail", other middle rails are commonly known as"cross rails".
Mullions - Smaller optional vertical boards that run between two rails,and split the door into two or more columns of panels, the term is usedsometimes for verticals in doors, but more often (UK and Australia) itrefers to verticals in windows.
Muntin - Optional vertical members that divide the door into smallerpanels.
Panels - Large, wider boards used to fill the space between the stiles, rails,and mullions. The panels typically fit into grooves in the other pieces, andhelp to keep the door rigid. Panels may be flat, or in raised panel designs.
Lite - a piece of glass used in place of a panel, essentially giving the door awindow.

Automatic / electric doors are powered open and closed either byelectricity, spring, or both. There are several methods by which itis activated:
1. A sensor detects traffic is approaching. Sensors forautomatic doors are generally:
A pressure sensor - e.g., a floor mat which reacts tothe pressure of someone standing on it.
An infrared curtain or beam which shines invisible lightonto sensors; if someone or something blocks thebeam the door is triggered open.
A motion sensor which uses low-powermicrowave radar for the same effect.
A remote sensor (e.g. based on infrared or radiowaves) can be triggered by a portable remote control,or is installed inside a vehicle. These are popular for
garage doors.2. A switch is operated manually, perhaps after security
checks. This can be a push button switch or a swipe card.
3. The act of pushing or pulling the door triggers the open andclose cycle. These are also known as power-assisteddoors.
