A door is a movable barrier used in buildings to provide access. Doors are held in place by a door frame. The earliest doors date back to ancient Egypt and were made of wood. Different types of ancient doors included those made of olive wood, elm, cedar, oak and cypress. Modern doors come in many styles and materials depending on their purpose and location within residential or commercial buildings. Common door types include French doors, sliding doors, bifold doors and flush doors.

1. WHAT IS A DOOR
A door is defined as a movable barrier , secured in an opening , known as a
door way through a building wall or partition for the purpose of providing
an access to the inside of a building or rooms of a building.
A door is held in position by a door frame , the members of which are
located at the sides and top of the opening or door way.

2. HISTORY OF DOORS
The earliest in records are those represented in the paintings of
the Egyptian tombs, in which they are shown as single or double doors, each in
a single piece of wood. In Egypt, where the climate is intensely dry, there would
be no fear of their warping, but in other countries it would be necessary to
frame them, which according to Vitruvius (iv. 6.) was done with stiles (sea/si)
and rails (see: Frame and panel): the spaces enclosed being filled with panels
(tympana) let into grooves made in the stiles and rails. The stiles were the
vertical boards, one of which, tenoned or hinged, is known as the hanging stile,
the other as the middle or meeting stile. The horizontal cross pieces are the top
rail, bottom rail, and middle or intermediate rails. The most ancient doors were
in timber, those made for King Solomon's temple being in olive wood (I Kings vi.
31-35), which were carved and overlaid with gold. The doors dwelt upon
in Homer would appear to have been cased in silver or brass. Besides Olive
wood, elm, cedar, oak and cypress were used. A 5,000-year-old door has been
found by archaeologists in Switzerland.[2]
SOME TYPES OF ANCIENT DOORS

3. LOCATION OF DOORS
• The designer or the planner should observe the folowing rules while deciding the location of
door
• The number of doors should be minimum for a room for better movement and for no
obstruction in the room
• From view point of utility of the accommodation and privacy of the occupants , doors ,
should preferably be located near the corner of a room
• The location , number and size of the windows are decided considering various factors
• From view point of good ventilation and free air circulation inside the room , the doors ,
should be located opposite walls facing each other

9. DESIGN AND STYLE
• Many kinds of doors have specific names, depending on their purpose. The most common variety of door is
the single-leaf door which consists of a single rigid panel that fills the doorway. Many variations on this basic
design are possible, such as the double-leaf door ordouble doors and French windows that have two adjacent
independent panels hinged on each side of the doorway.
• A half door or Dutch door[7] or stable door is divided in half horizontally. Traditionally the top half can be opened
to allow a horse or other animal to be fed, while the bottom half remained closed to keep the animal inside. This
style of door has been adapted for homes.Saloon doors are a pair of lightweight swing doors often found
in public bars, and especially associated with the American west. Saloon doors, also known as cafe doors, often
use bidirectional hinges which close the door regardless of which direction it is opened by incorporating springs.
Saloon doors that only extend from knee-level to chest-level are known as batwing doors.
• A blind door, Gibb door, or jib door is a door with no visible trim or operable components. It is designed to blend
with the adjacent wall in all finishes, and visually to be a part of the wall, a disguised door.[8]
• A barn door is a door characteristic of a barn. They are often/always found on barns, and because of a barn's
immense size (often) doors are subsequently big for utility.
• A French door is a door style consisting of a frame around one or more transparent or translucent panels (called
lights or lites) that may be installed singly, in matching pairs, or even as series. A matching pair of these doors is
called a French window as it resembles a door-height casement window. When a pair of French doors is used as a
French window, the application does not generally include a central mullion (as do some casement window pairs),
thus allowing a wider unobstructed opening. The frame typically requires a weather strip at floor level and where
the doors meet to prevent water ingress. An espagnolette bolt may allow the head and foot of each door to be
secured in one movement. The slender window joinery maximizes light into the room and minimizes the visual
impact of the doorway joinery when considered externally. Often, the doors of a French

preserving privacy and preventing the passage of light to the interior. Being relatively weak structures, they are most
commonly used forwardrobes and drying rooms, where security is of less importance than good ventilation, although a very
similar structure is commonly used to form window shutters. Double louvred doors were introduced into Seagate, built in
Florida in 1929 by Gwendolyn and Powel Crosley, that provided the desired circulation of air with an added degree of privacy
in that it is impossible to see through the fins in any direction.
• A composite door is a single leaf door that can be solid or with glass, and is usually filled with high density foam. In the
United Kingdom, it is common for composite doors to be certified to BS PAS 23/24[9] and be compliant with Secured by
Design.
• 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 H Mason 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.
• A moulded door has the same structure as that of flush door. The only difference is that the surface material is a moulded
skin made of MDF. Skins can also be made out of hardboards.
• A ledge and brace door is a door made from multiple vertical planks fixed together by two horizontal planks (the ledges) and
kept square by a diagonal plank (the brace).
• A wicket door is a pedestrian door built into a much larger door allowing access without requiring the opening of the larger
door. Examples might be found on the ceremonial door of a cathedral or in a large vehicle door in a garage or hangar.
• A bifold door is a door unit that has several sections, folding in pairs. Wood is the most common material, and doors may
also be metal or glass. Bifolds are most commonly made for closets, but may also be used as units between rooms.
• A sliding glass door, sometimes called an Arcadia door or a Patio door, is a door made of glass that slides open and
sometimes has a screen (a removable metal mesh that covers the door).
• Australian doors are a pair of plywood swinging doors often found in Australian public houses. These doors are generally red
or brown in color and bear a resemblance to the more formal doors found in other British Colonies' public houses.
• A false door is a wall decoration that looks like a door. In ancient Egyptian architecture, this was a common element in a
tomb, the false door representing a gate to the afterlife. They can also be found in the funerary architecture of the desert
tribes (e.g., Libyan Ghirza).

BATTENED AND LEDGED DOOR
This is the simplest form of door which is frequently used for
narrow openings . The use of this type of door is prefered where
cost is main factor rather then the strength and material.

29. FRAMED AND PANELLED DOORS
Frame-and-panel doors nearly always look pretty good. The reason is that
harmony automatically results from the construction: as you can see in the
drawings, all the lines follow the architecture of the frame. Nevertheless, if
you build without paying attention to proportions and details, while the door
might not run all the way to ugly, it probably won’t look its best. There are
many small decisions to be made, and getting them right is what makes a door
really pleasing to the eye.

52. REVOLVING DOORS
A revolving door has several wings or leaves,
generally four, radiating from a central shaft,
forming compartments that rotate about a
vertical axis. A revolving door allows people to
pass in both directions without colliding, and
forms an airlock maintaining a seal between
inside and out.
A pivot door, instead of hinges, is supported on
a bearing some distance away from the edge, so
that there is more or less of a gap on the pivot
side as well as the opening side. In some cases
the pivot is central, creating two equal
openings.

55. REVOLVING DOOR

56. SWING DOORS
Most doors are hinged along one side to allow the door to
pivot away from the doorway in one direction but not in
the other. The axis of rotation is usually vertical. In some
cases, such as hinged garage doors, the axis may be
horizontal, above the door opening.
Doors can be hinged so that the axis of rotation is not in
the plane of the door to reduce the space required on the
side to which the door opens. This requires a mechanism
so that the axis of rotation is on the side other than that in
which the door opens. This is sometimes the case in trains
or airplanes, such as for the door to the toilet, which
opens inward.
A swing doors has special double-action hinges that allow
it to open either outwards or inwards, and is usually
sprung to keep it closed.

59. APPLICATIONS OF DOORS
Architectural doors have numerous general and specialized uses. Doors are
generally used to separate interior spaces (rooms, closets, etc.)
for privacy, convenience, security, and safety reasons. Doors are also used to
secure passages into a building from the exterior for reasons of safety
and climate control.
Doors also are applied in more specialized cases:
A trapdoor is a door that is oriented horizontally in a floor or ceiling, often
accessed via a ladder.
Blast-proof doors are constructed to allow access to a structure but also to
provide protection from the force of explosions.
A garden door is any door that opens to a garden or backyard. This term is
often used specifically for French windows, double French doors (with lites
instead of panels), in place of a sliding glass door. The term also may refer to
what is known as patio doors.
A jib door is a concealed door, whose surface reflects the moldings and
finishes of the wall. These were used in historic English houses, mainly as
servants' doors.
