2. Doors may be defined as an openable
barrier secured in a wall opening. It is
provided to give an access to inside of a
room.
It consists of two parts:-
1. Door frame
2. Door shutter

3. SOME TECHNICAL TERMS
FRAME:- It is an assembly of horizontal and
vertical members, forming an enclosure, to which
the shutters are fixed
SHUTTER:-These are the openable parts of a door
or window.
HEAD:-This is the top or uppermost horizontal
part of frame
SILL:-This is the lowest or bottom horizontal part
of a window frame, not provided in door frames.
HORN:- These are the horizontal projections of a
frame..

4.  The number of door should be kept minimum
 The location of door & window should meet functional requirements
of the room.
 The door should not be kept in the centre of the wall.
 The window should be located in opposite wall, facing a door or
another window, to achieve cross ventilation.
 From the point of view of fresh air, a window should be located on the
northern side of of a room.
 The sill should be located about 70 t0 80 cm about floor level of the
room.

5. Types of doors mainly classified on the basis of-
 Arrangement of components
 Method or manner of construction
 Working operations
 Metal doors
On the basis of arrangement of components:-
This includes four types:-
1. Battened & ledged doors
2. Battened, ledged and braced doors
3. Battened, ledged and framed doors
4. Battened, ledged,braced and framed doors

6.  These doors consist of vertical boards
called battens which are nailed or screwed
to the horizontal members, called ledges .
Often the battens are a-bout 15 to 18 cm
wide and 2 to 3 cm thick. Doors made
with narrow battens like these have a
better appearance.
Battened & ledged doors
This is a ledged and battened door to which
braces have been added to prevent sagging.
These braces must slope upwards from the
hinge edge of the door, and they are housed
with a skew notch into the ledges.
Battened, ledged and braced doors

7.  It is improved version of battened and ledged
doors with provision of frame. Two vertical
members known as styles are provided
Battened, Ledged & Framed Doors
Battened, Ledged , Braced & Framed Doors
Same as above with extra braces.
These doors consist of a frame made up of stiles (a), a
top rail (b), a bottom rail (c) and sometimes an
intermediate rail (d). into this framework a plywood
panel (e) is fitted. This panel may fit into a groove or a
rebate.
Framed & Panelled Door

8.  These are provided where the visibility of the interior
of the room is required.
Glazed or Sash Doors
The flush door with a framed core is a type of door that we
frequently make in Rural Building. This door consists of a
frame which has stiles, top and bottom rails, and narrow
intermediate rails. It is covered on each side by a sheet of
plywood Plywood-covered flush doors cannot be used where
they will be exposed to rain and sun.
Flush Doors
These permit free ventilation through
them and at the same time maintain the
privacy of the room.
Louvered Doors

9. .
Wire gauged doors
Wire gauge or fly proof door shutters are
fixed to provide free air circulation and
prevent mosquitoes, flies, insects etc.
from entering into the building
These are provided only at public places
to provide entrance to one and exit to
the other person.
Revolving Doors
A sliding door is a type of door which
opens horizontally by sliding, whereby
the door is either mounted on or
suspended from a track
Sliding Doors

10.  A door that swings on a double
hinge; opens in either direction
Swing Doors
Collapsible Steel Doors
Mainly provided in godowns, workshop,
public windows and etc.
A roller shutter, roller door or sectional
overhead door is a type of door or window
shutter consisting of many horizontal slat
hinged together. The door is raised to open it
and lowered to close it. On large doors, the
action may be motorized. It provides
protection against wind and rain.
Rolling Steel Shutter Door

11.  Mainly provided in godowns,
workshop, public windows and etc. It
is quite strong.
Mild Steel Sheet Door
Corrugated Steel Doors
Exactly same as the above type, except
that corrugated steel sheets are welded
to shutter frame instead of MI sheets.
These are composite doors of plywood
and mild steel and are reasonably fire
proof.
